Sebastião Salgado is renowned for his poignant portraits that depict humanity’s struggles in a tumultuous world. His impactful work covers significant events, from the assassination attempt on U.S. President Ronald Reagan to conflicts in Africa, the Balkans, and the Middle East, and also chronicles the lives of workers and immigrants around the globe.

After documenting the Rwandan genocide, Salgado faced a personal crisis and withdrew to his family’s Brazilian farm, disheartened by the environmental devastation. Motivated by what he observed, he dedicated himself to restoring the Atlantic rainforest, which reignited his passion for photography. His acclaimed project, Genesis, captures the planet’s “untouched and undestroyed” areas, from Alaska’s mountains to the Amazon’s indigenous communities. These journeys transformed him into a staunch environmental advocate, as expressed in a separate interview.

Glaciers is a newly released book posthumously showcasing 65 breathtaking black-and-white images of glaciers, taken during Salgado’s Genesis project. These captivating frames capture both grand and subtle movements within frigid landscapes. The main image features a parade of penguins leaping from an iceberg into the turbulent waters of the South Sandwich Islands, while another captures a seabird swooping near an ice tower within the same region.

However, these majestic images remind us that glaciers are rapidly vanishing, with approximately 1,000 disappearing each year. The situation is dire: current projections indicate that nearly 80% of glaciers may be lost by 2100, which includes vast regions in western Canada, the United States, and the Alps.

Stunning Close-Up of Arp 4 Captured by Hubble Space Telescope

Discover the latest stunning image captured by the NASA/ESA Hubble Space Telescope, showcasing Arp 4, an intriguing visual pair of galaxies located in the constellation Cetus.

For more details, explore Arp 4, which features the bright spiral galaxy MCG-02-05-050a alongside the larger spiral galaxy MCG-02-05-050.

Located within the constellation Cetus, this galaxy pair was first discovered by Dutch-Canadian astronomer Sidney van den Bergh in 1959.

Arp 4 stands as the fourth entry in Halton Arp’s Atlas of Peculiar Galaxies and belongs to the section focusing on “Galaxies with Low Surface Brightness.”

“The term ‘Arp 4’ derives from the Atlas of Peculiar Galaxies compiled by astronomer Halton Arp during the 1960s,” Hubble astronomers explained.

“These ‘unusual galaxies’ were chosen for photography to illustrate their distinct and non-standard shapes, providing insights into galaxy evolution.”

Hubble’s mission has transformed our understanding of galaxies, revealing captivating examples from Arp’s Atlas, including Arp 4.

The initial galaxies in this catalog, including Arp 4, exhibit low surface brightness, rendering them faint and challenging to observe.

“The larger galaxy, cataloged as MCG-02-05-050, features fragmented arms and a dim disk, perfectly fitting this description,” the astronomers noted.

“In contrast, its smaller counterpart, MCG-02-05-050a, is considerably brighter and more dynamic as a spiral galaxy.”

“Crucially, these galaxies are not in close proximity,” the researchers emphasized.

“The prominent blue galaxy, MCG-02-05-050, lies 65 million light-years from Earth.”

“Meanwhile, the brighter, smaller galaxy MCG-02-05-050a is positioned at an impressive 675 million light-years, over ten times farther away.”

This positioning likely suggests that MCG-02-05-050a is the more substantial of the two, while MCG-02-05-050 is relatively smaller.

“This visual pairing is simply an unlikely coincidence,” the astronomers added.

“Despite the absence of a physical connection, we can enjoy the unique sight of Arp 4 as an enthralling duo adorning our night sky.”

Nocturnal Spiders Employ Captured Fireflies as Luminous Lures to Entice Prey

Sheet Web Spider Psechrus Clavis is known to utilize the coloration and web of its own body as visual cues to effectively capture and consume insects. Interestingly, it doesn’t immediately eat the male fireflies, referred to as Daifan Lampaloid; instead, these spiders retain them on the web, allowing the fireflies to continue emitting bioluminescent signals for up to an hour. This observation has raised intriguing questions among a research team from Tunghai University, the University of New South Wales, the Sydney Institute of Technology, and the National Museum of Natural Sciences in Taiwan.

Researcher I-Min TSO and colleagues at Tunghai University documented Psechrus Clavis retaining fireflies on the web while these insects continued to emit bioluminescent light for up to an hour.

They noted that the spiders periodically check for the captured fireflies.

Fascinated by this peculiar behavior, the researchers designed an experiment to see if it serves as a hunting strategy.

The experiment involved placing firefly-like LEDs on the actual sheet spider web, using other webs as controls.

The results indicated that the web with LEDs attracted three times as many prey compared to the control web.

This figure increased to ten times more prey when actual fireflies were visible.

The findings affirm that the presence of captured fireflies enhances the spider’s hunting success.

Researchers also discovered that the majority of captured fireflies are male and likely mistaken for potential mates.

“Our findings underscore the previously unrecognized interaction where Firefly Signals, intended for sexual communication, also benefit spiders,” remarked Dr. TSO.

“This study provides new insights into how sit-and-wait predators can adapt to attract prey, revealing the intricate complexities of predator-prey interactions.”

“This behavior may have evolved in sheet web spiders as a way to avoid the energy costs associated with producing their own bioluminescence, similar to anglerfish.”

“Instead, spiders can leverage the allure of their prey’s glow to attract their own targets.”

Video recordings taken during the experiments show sheet web spiders employing various tactics when interacting with different prey species.

The spider swiftly consumes a moth caught in the web but takes its time with the trapped fireflies.

“The varying treatment of prey suggests that spiders may use specific cues to differentiate between prey species and adjust their responses accordingly,” explained Dr. TSO.

“We hypothesize that the bioluminescent signals of fireflies help spiders to fine-tune their handling behavior towards different types of prey.”

This study was published in Journal of Animal Ecology.

Captured a Single Electron at an Unmatched Speed

Rapid detection of individual electrons proves challenging

agsandrew/shutterstock

Now, detecting a solitary electron with a resolution of a trillion can be achieved in a mere second. This breakthrough could be crucial for advancing new generations of quantum electronic devices.

While conventional electronic circuits are packed with numerous electrons, their interactions often diminish their efficiency and performance. Is it possible to effectively manage a single electron to create a speedy and efficient circuit that operates with one electron at a time? Masaya Kataoka from the UK’s National Institute of Physics (NPL) and his team have advanced this objective by developing highly precise techniques for electron detection.

They introduced two electrons at different locations within a thin layer of the semiconductor gallium halide arsenide. The charged particles moved rapidly toward each other. When their paths drew near, the force between the electrons caused them to diverge, altering their trajectories. The researchers tracked one of the electrons and leveraged this deflection to identify the other electrons. They managed to detect it within 6 trillion interactions, which is roughly 100 times quicker than previous methods.

“Our experiments can be regarded as electrons acting as the world’s smallest sensors, detecting the world’s smallest object,” remarks Kataoka.

Team member John Fletcher at NPL explains that interactions among electrons can occur over trillion-second intervals. With this timescale now achievable, researchers are beginning to explore what two electrons do within a device and leverage this knowledge to design new electronic innovations.

Vyacheslavs Kashcheyevs from the University of Latvia believes this work could mark a pivotal point in the creation of a new generation of electronic devices reliant on high-speed single electrons. He elaborates that a single electron is inherently a quantum entity, which means future devices may harness their quantum characteristics directly, similar to their current applications in quantum computing and communication.

Researchers envision that a single-electron device could accomplish tasks akin to those performed by quantum devices that utilize a single photon, yet it would be significantly smaller. Such electron-based devices could even be integrated onto chips for convenience, says Christian Flindt from Aalto University in Finland. He emphasizes that this detection method will serve as the foundational building blocks for these potential applications.

The findings are also expected to enhance the understanding of electrical currents. Rolf Haug from Hannover University of Leibniz, Germany, notes that the current standards used for measuring current could be refined by implementing the “electron pump” utilized by the team to inject electrons in their experiments, he states.

Orca Captured Engaging in a “Tongue Kiss” in the Wild for the First Time

In a remarkable encounter with citizen scientists off the coast of Norway, a duo of orcas was seen engaging in “kissing” behavior in the wild for the very first time.

The footage captured by the group displays the pair gently nodding at each other, accompanied by “tongue nibbling.”

While similar behaviors have been documented before, this marks the first instance of such interactions being observed in a natural habitat.

During the video, the orcas came within 10-15 meters (30-50 feet) of each other, sharing three brief moments of affection above the water’s surface for a duration of two minutes.

https://c02.purpledshub.com/uploads/sites/41/2025/07/Orca-kissing-video.mp4
The footage captures a serene moment of connection between the two whales.

“This behavior has only been documented in orcas under human supervision,” said Dr. Javier Almunia from Loro Parque in Spain, as reported by BBC Science Focus. He was part of a recently published study utilizing observation videos from marine environments.

“Witnessing it in the wild indicates that such intricate social behaviors extend beyond captivity and are likely integral to the species’ natural social behavior.”

Orcas are known for their strong social structures, employing intricate behavioral systems to form and maintain social relationships.

For marine biologists, these observations are crucial for understanding orca interactions.

“Gaining insight into the social behavior of wildlife is essential for understanding their communication, bonding, and cooperation—key elements for their survival and well-being,” noted Almunia.

Unfortunately, these wild behaviors are rarely seen and require a fair amount of luck to witness at the right moment.

While studying animals in captivity is safer and more accessible, their behaviors often differ significantly from those observed in the wild.

https://c02.purpledshub.com/uploads/sites/41/2025/07/Nibbling-at-Loro-Parque.mov
Orcas in captivity have previously been observed “nibbling” their tongues at each other.

A Remarkable Encounter

The video was filmed on January 11, 2024, when two whales were observed by a fortunate group of snorkelers diving in Kavanangenfjord, northern Norway.

This area is known as a gathering spot for marine mammals, making it an ideal location for observing orcas due to its clear waters.

The group had the opportunity to watch the orcas under the guidance of experienced expedition leaders.

However, the study emphasized that while tourist excursions can lead to valuable scientific observations, “it is widely recognized that activities like whale watching and swimming can pose significant risks to wild populations.”

Orcas, often referred to by the misleading nickname “Killer Whale,” actually belong to the dolphin family. The latter portion of this nickname is accurate, as all dolphins are categorized as “toothed whales.”

Nevertheless, the term “killer” is misleading, as there are no documented cases of wild orcas intentionally harming humans.

The name stems from an ancient mariner who observed orcas hunting other large whales.

“They were originally called ‘whale killers,’ a term that evolved into ‘killer whale’,” explained Almunia.

“While orcas are indeed apex predators, they are also incredibly intelligent and social animals with complex cultures and strong familial bonds. They play a critical role as top predators within marine ecosystems.”

Investigating Tesla’s Robotaxi Launch: Irregular Driving Captured in Video

Major US transportation safety regulators are seeking information from Tesla following videos that appear to show the vehicles exceeding speed limits and autonomous robotaxis driving in the wrong lanes. The company unveiled its service in Austin, Texas, over the weekend.

Tesla has notably expedited the initial limited rollout of its Robotaxis, with some influencers being paid to showcase their experiences. However, rather than serve as effective promotion, these videos seem to have drawn the scrutiny of the National Highway Traffic Safety Administration (NHTSA), particularly as the cars struggled to adhere to traffic regulations.

“The NHTSA is aware of the mentioned case and is in communication with the manufacturer to gather further information,” the agency stated.


The debut of Robotaxi over the weekend featured about 10 “safety drivers” in the passenger seats navigating Austin’s designated areas. Tesla CEO Elon Musk promoted the launch as a significant achievement and committed to enhancing driving safety, but some influencers shared videos that appeared to show glitches or speeding incidents involving the Robotaxis.

One video shared by a Tesla investor, who previously hosted a podcast regarding the brand, displayed a Robotaxi wobbling after misinterpreting a left turn, crossing over a double yellow line before correcting itself. During this time, there were no oncoming vehicles.

In another clip, a pro-Tesla YouTuber praised a car for maintaining speed within legal limits.

Musk has placed significant stakes on the future of the carmaker tied to the Robotaxi program, having long presented a vision where millions of self-driving cars traverse cities globally. Both regulators and investors are closely examining whether Tesla can convert these prospects into tangible outcomes and if it can sustain its operations. Musk’s prolonged history of unmet promises.

“We anticipate millions of Teslas to function entirely autonomously by next year,” Musk declared during an earnings call in April, having made a similar assertion in 2019.

The NHTSA has not pre-emptively greenlit new technologies or driving systems, the statement mentioned. Instead, the manufacturer affirms that the vehicle meets the agency’s standards, while investigators assess potential safety defects. The NHTSA reviews the reports and related information to determine how to tackle road safety concerns.

“NHTSA will persist in enforcing regulations for all automobile manufacturers in accordance with the Automobile Safety Act and our data-driven, risk-based investigation methodology,” the agency remarked.

Robotaxis has gained heightened significance for Tesla this year, particularly as first-quarter sales declined and profits plummeted by 71% year-on-year. Despite diminishing revenues, Musk asserted that Tesla’s Robotaxis are destined to be the future of transportation.

In addition to a preliminary inquiry into Robotaxis, the NHTSA is also conducting an open investigation that began in 2024 to assess the safety of Tesla’s “full self-driving” mode under conditions of reduced visibility. Tesla was reported to have deployed autonomous functions which resulted in a fatality of a 71-year-old woman in 2023 while driving in Arizona during sunset when glare affected road visibility.

Images of the Sun’s Poles Captured by Solar Orbiter

All previously observed images were captured from the Sun’s equatorial region. This is due to the fact that Earth, along with other planets and operational spacecraft, orbits the Sun in a flat disk known as the zodiac plane. By adjusting its orbit away from this plane, the ESA Solar Orbiter spacecraft unveils the Sun from an entirely new perspective.

Professor Carol Mandel, ESA’s Director of Science, remarked:

“The Sun, being our closest star, is essential for life but can also disrupt modern power systems in space and on Earth. Therefore, understanding its mechanisms and predicting its behavior is crucial.”

“The new and unique perspectives provided by the Solar Orbiter mission signal the beginning of a new era in solar science.”

The images were captured by three different scientific instruments on the Solar Orbiter: Polarimetry and Helioseismology Imager (PHI), Extreme Ultraviolet Imager (EUI), and Spectral Imaging of the Coronal Environment (SPICE).

“Initially, I was uncertain of what to anticipate from these observations. The solar pole is truly a Terra Incognita,” said Professor Sami Solanki, leader of the PHI team at the Max Planck Institute for Solar System Research.

This collage shows the Antarctic of the Sun captured on March 16-17, 2025, as the solar orbiter observed from a 15° angle relative to the solar equator. This marked the first high-angle observation campaign just days before achieving its current maximum viewing angle of 17°. Image credits: ESA/NASA/Solar Orbiter/PHI/EUI/SPICE Team.

Each instrument on the Solar Orbiter observes the Sun differently.

PHI captures images of the Sun in visible light (top left) and maps its surface magnetic field (top center).

EUI images the Sun in ultraviolet light (top right), unveiling the corona, a multi-million-degree gas layer in the Sun’s outer atmosphere.

SPICE captures light from various temperatures of charged gases at the Sun’s surface, thereby revealing different layers of its atmosphere.

By analyzing and comparing observations from these three imaging instruments, we can understand how materials in the Sun’s outer layer move.

This could uncover unexpected patterns like polar vortices (swirling gases), reminiscent of those found around the poles of Venus and Saturn.

These innovative observations are crucial for understanding the solar magnetic field, particularly why it inverts every 11 years, aligning with peaks in solar activity.

Current predictive models for the 11-year solar cycle struggle to accurately forecast when and how the Sun will reach its peak activity.

https://www.youtube.com/watch?v=tu4dcdgamm0

One of the primary scientific discoveries from Solar Orbiter’s polar observations is that the solar magnetic field is currently disordered in the Antarctic region.

While traditional magnets exhibit defined Arctic and Antarctic poles, magnetic measurements from the PHI instrument demonstrate that both polarities exist in the Antarctic region of the Sun.

This phenomenon occurs only briefly during each solar cycle when the magnetic field is reversed at the solar maximum.

Following this reversal, a single polarity gradually takes over the solar pole.

After 5-6 years, the Sun reaches the minimum phase of its cycle, during which its magnetic field is most organized, resulting in the lowest activity levels.

“How this accumulation occurs is not fully understood, so the timing of the solar orbiter’s high latitude observations is remarkably advantageous for tracking the entire process,” noted Professor Solanki.

PHI’s perspective on the solar magnetic field contextualizes these measurements.

The intensity of color (red or blue) signifies the strength of the magnetic field along the line of sight from the solar orbiter to the Sun.

The strongest magnetic fields manifest as two bands flanking the solar equator.

Dark red and blue regions highlight areas of concentrated magnetic fields associated with solar spots on the Sun’s surface (photosphere).

Additionally, both the Antarctic and Arctic regions exhibit red and blue spots, indicating a complex, constantly evolving solar magnetic structure on a smaller scale.

Another noteworthy discovery from the Solar Orbiter comes from the SPICE instrument.

This imaging spectrograph analyzes light (spectral lines) emitted by specific chemical elements such as hydrogen, carbon, oxygen, neon, and magnesium, at known temperatures.

Over the last five years, SPICE has employed this method to uncover processes occurring in various layers of the Sun’s surface.

For the first time, the SPICE team was able to utilize precise spectral line tracing to measure the velocity of moving solar material.

This technique, known as “Doppler measurement,” is named after the effect observed with an ambulance siren as it approaches and recedes, causing a change in pitch.

The resulting velocity map illustrates the movement of solar material within specific solar layers.

“Measurements from high latitudes, made possible with the Solar Orbiter, will revolutionize solar physics,” stated Dr. Frederic Aucele, leader of the SPICE team at Paris Sacree University.

Capuchin Monkey Captured on Camera with a Baby Howler Monkey

A baby Howler Monkey clings to the back of an older male monkey, whose small fingers grip the fur. However, they are not related and belong to different species.

Researchers have uncovered unexpected evidence of what they refer to as a monkey temptation while analyzing video recordings from a small island in Panama. Between 2022 and 2023, at least 11 baby Howler Monkeys were observed being carried by Capuchin Monkeys.

“This discovery was quite shocking,” remarked Zoe Goldsborough, a behavioral ecologist at the Max Planck Institute for Animal Behavior in Germany. “Nothing like this has been documented in the animal kingdom.”

The motivation behind the monkeys’ actions is currently being studied. Capuchins are cat-sized monkeys indigenous to South and Central America. They are intelligent, long-lived, and observed to learn new behaviors from one another. One group in Panama has even learned to use stones as tools to crack nuts and open seafood.

Goldsborough and her colleagues from both the Max Planck Institute and the Smithsonian Tropical Research Institute have set up over 80 cameras to investigate Capuchin tool usage, yet were surprised to witness the first baby Howler appearing in early 2022.

The footage revealed Capuchin Monkeys walking while using a stone tool, with a Howler baby secured on the back of one. However, the cameras failed to capture the abduction event. Scientists believe it likely occurred in the trees, where Howlers typically reside.

“Our perspective on this story is limited,” stated Margaret Crofoot, co-author from Max Planck and Smithsonian. The findings were published in the journal Current Biology on Monday. In most instances, including all recorded cases, the baby Howler Monkey did not survive, researchers said. Infant Howler monkeys are typically carried by their mothers while nursing, and all the babies featured in the videos were mere weeks to months old—far too young to be weaned.

“I hope that perhaps some have escaped and returned to their mothers, but we truly do not know,” Crofoot added.

The footage documented numerous occasions of young male Capuchins carrying a baby Howler, which likely succumbed to starvation. Many species, including gorillas and Orcas, have also been observed carrying their deceased offspring, but the reasons remain unclear to scientists.

What prompted the Capuchin to do this? There were no indications of an intentional attack on the baby, nor were there signs of predation.

“We spent countless hours trying to understand the motivation behind this behavior,” Goldsborough explained.

The first Capuchin to carry the baby may have acted out of confused “compassionate motivation” or parental instinct, showing gentleness towards the infant. Other males then replicated this behavior.

Researchers believe that the Capuchins did not purposefully harm the baby. So far, only a single group of Capuchins is known to exhibit this behavior.

This study highlights “significant behavioral variations among social groups of the same species.”

NASA’s Dom Petit Captured Stunning Photos from the ISS Over 220 Days

Don Pettit, NASA’s oldest active astronaut, made his return to Earth on April 20th, coinciding with his 70th birthday. This marked the end of his fourth mission, a demanding 220-day stay at the International Space Station.

Throughout his time aboard the space station, Pettit engaged in various experiments, interacted with students, and exercised extensively to maintain his health and combat bone density loss. However, his most captivating contribution was through his photography.

For many on Earth, going to space is simply a dream. “I caught a glimpse of how they perceive my image,” said Pettit during a press conference following his return to Japan.

Pettit mentioned that dedicated photographers always carry a camera. “I could gaze out of the window and enjoy the stunning views,” he described. “But every time I look out, I am just enjoying it, saying to myself, ‘Wow, look at that. Oh, there’s a flash. What’s happening there?’ and, ‘Ah, a volcano appears.’ Then I think, ‘Where’s my camera?’

At times, he would set up five different cameras simultaneously in the cupola module, where seven windows offered sweeping vistas of space and Earth.

Capturing images in space shares similarities with night photography; the stars are faint and require longer exposure times to gather sufficient light. However, in orbit, everything is in constant motion, with the space station racing at 5 miles per second while the Earth spins beneath.

At times, Pettit embraced the dynamic beauty. The shimmering lines blurred under the light showcased the stars tracing arcs across the night sky.

“These meld science with art,” Pettit noted on X. “There are so many techniques to observe, or you can simply sit back and think, ‘How cool!’

His camera was fitted with a “trajectory fitting tracker,” a homemade device that gradually adjusts for the space station’s movements, keeping the lens focused on a particular point in the sky.

Thanks to this tracker, he was able to capture a 10-second exposure of the Milky Way shining above the cloudy Pacific Ocean just before dawn, revealing a captivating blue-purple glow from sunlight scattering through nitrogen in Earth’s atmosphere.

The sidereal tracker also contributed to capturing the image below from the windows of the docked SpaceX Crew Dragon spacecraft.

The photo reveals the large and small Magellanic Clouds, the closest galaxies to our Milky Way on a cosmic scale.

In April, Pettit filmed the mesmerizing rhythmic pulsations of the aurora, a glowing phenomenon caused by high-energy solar particles interacting with atmospheric molecules.

On occasion, vibrant lights were the result of human activity, not celestial events. The green lines seen in this photo are similar in color to the aurora but actually result from fishing boats off Thailand attracting squid.

While photographing Earth, Pettit recorded lightning striking in the upper atmosphere above the Amazon Basin in South America. These videos captured time intervals ranging from 6 to 33 seconds, showcasing more intricate details of the flashes.


The Betoshiboca River in Madagascar reminded Pettit of the visual patterns seen in human eyes’ blood vessels.

Similar to wildfires, urban areas intensify in brightness at night.

Pettit seized the opportunity to document spacecraft launching and returning to Earth, including a test flight of a SpaceX Starship rocket from Texas last November…


…and the docking of the SpaceX Dragon spacecraft, scheduled to transport cargo to the space station in December.

During his mission, Pettit also designed an entertaining science experiment. One showcased electrically charged water droplets dancing around a Teflon knitting needle. “I aim to do in space what can only be done in space,” he stated. “I’m worried that when I return, I’ll have to catch up on all the TV shows.”

In another experiment, he injected food coloring into a droplet of water, producing a sphere resembling Jupiter or a pristine marble.

Pettit also dissolved antacid tablets in water. In a microgravity environment, the escaping bubbles create entirely different patterns of pop, fizz, and hiss compared to on Earth.

He even froze thin water ice wafers at minus 140 degrees Fahrenheit. “What can you do with a freezer in space?” He wrote on X. “I decided to grow a thin layer of water ice just for the fun of it.”

Photographing the ice layer through a polarizing filter revealed intricate crystal formations.


While Pettit holds the title of the oldest NASA astronaut, he is not the oldest person to orbit Earth; that honor goes to John Glenn, who flew around the Earth in 1962 and again in 1998 at the age of 77.

Pettit is also not the oldest individual to spend time aboard the International Space Station; that distinction belongs to private astronaut Larry Connor, who was 72 during his two-week mission in 2022, organized by Axiom Space in Houston.

“I’m only 70, with a few good years ahead of me,” Pettit remarked during a news conference. “We’ve managed to squeeze in another flight before we had to finalize the rocket nozzle.”

Inside the Mission Where He Captured His First Video of a Giant Squid

As it emerged, it was yet another journey into the abyss, cloaked in darkness: mid-water, a delicate, ethereal shape transitioning into another realm.

A remotely operated vehicle, Subathian, recorded the first footage of a giant squid stable in its natural habitat in the southern ocean near Antarctica. The giant squid can grow up to 10 meters (33 feet) in length, making it the heaviest invertebrate on the planet, yet until now, it remained elusive.

This remarkable discovery occurred during a 35-day expedition to the Southern Sandwich Islands, a secluded volcanic arc in the Southern Ocean, aboard the Folcole (too).

The expedition aimed to expedite the discovery of deep-sea species, but nobody anticipated encountering one of the ocean’s most elusive giants.

“We were operating Subathian at a depth of about 2,000 meters that day for trench work,” stated Dr. Michelle Taylor, Chief Scientist of the Expedition and Senior Lecturer at Essex University, as reported by BBC Science Focus.

While Subathian navigated through the cerulean waters, we remained in the control room, surrounded by high-resolution cameras and screens displaying sensor data from the vehicle. A group of scientists observed intently as we monitored the water column.

https://www.youtube.com/watch?v=lzpog9h8hlo

On March 9th, at a depth of approximately 600 meters (nearly 2,000 feet), the pilot spotted something and began to hover.

“None of us aboard were squid specialists, but we quickly recognized it as a stunning glass squid,” Taylor recounted. “We documented it for about three minutes before resuming our mission to explore the ocean floor.”

The giant squid is among the planet’s most enigmatic creatures. Until now, they had only been seen as dead specimens—either accidentally caught by fishing boats or found in a whale’s stomach. Documenting a living specimen is akin to discovering a unicorn in marine biology.

Furthermore, the squid was not yet fully grown. “It was a juvenile,” Taylor explained. “It lacked some physical features of adult squid, but it was definitely not fully developed. Its size was quite modest for a giant squid.”

The footage streamed live on YouTube during the dive was initially flagged by audience members.

Taylor consulted with Dr. Kat Bolstad, a cephalopod expert at Auckland Institute of Technology, along with other colleagues, who confirmed their identification with the aid of the 4K video footage captured during the dive.

Telltale clues included a distinctive hook along the squid’s arm.

“[Knowing it’s a colossal squid], I find it both beautiful and extraordinary,” Taylor remarked.

While the giant squid garnered headlines, it was not the singular highlight of the Folcole (too) expedition. About a month ago, researchers also captured the first in situ footage of a glacial glass squid.

Both sightings resulted from lengthy, meticulous dives conducted by Subathian, which can descend up to 4,500 meters (3 miles), enhancing the role of “telepresence” in scientific exploration.

This is the first confirmed footage of a glacier glass squid captured in January – Rov Subathian/Schmidt Ocean Institute

“It’s a new milestone, bringing the world into the deep sea in ways that were once impossible,” Taylor states. “Science enthusiasts and the general public can engage directly with our findings, often possessing extensive knowledge about what we observe.”

Taylor emphasizes that the mission’s deeper purpose transcends mere discovery; it aims to enhance the understanding and protection of deep-sea life.

“This is the last frontier,” she emphasizes. “It’s perplexing why we pursue other planets when we barely comprehend our own oceans.”

The Ocean Census seeks to expedite the discovery of new species, yet this process remains painstakingly slow. Often, it takes over a decade from specimen collection to formal recognition.

In its initial years, the project has already documented more than 800 new species, focusing on uncharted areas and fostering collaboration with a global network of taxonomists.

The sighting of the giant squid may have been serendipitous, but for Taylor, it marks merely the beginning.

“There is still much left to discover,” she asserts.

New Images of Messier 77 Captured by Hubble Space Telescope

NASA has released an incredibly beautiful image taken by the Hubble Space Telescope for the Barred Spiral Galaxy Messier 77.

Messier 77 is located 62 million light years from Earth in the constellation of Cetus.

Also known as the Squid Galaxy, NGC 1068, Leda 10266, and Cetus A. This galaxy is 9.6 in size.

It was discovered in 1780 by French astronomer Pierre Messhin and originally identified it as a nebula.

Mechine then conveyed the discoveries to her colleague, the French astronomer Charles Messier.

Messier believed that the very bright objects he saw were a herd of stars, but it was realized that technology had truly achieved its position as a galaxy.

“The Messier 77 designation comes from the location of the Galaxy, a well-known catalogue edited by French astronomer Charles Messier,” the Hubble astronomer said in a statement.

“Pierre Messhin, another French astronomer, discovered the galaxy in 1780.”

“Messier and Messhin were both comet hunters cataloguing ambiguous objects that could be mistaken for comets.”

“Messier, Méchain and other astronomers of that era mistaken the Squid Galaxy for either a spiral nebula or a star cluster.”

“This false characteristic is not surprising. For over a century, we pass between discovering squid galaxies and the realization that the “spiral nebulae” scattered across the sky are not part of our galaxies, but are actually millions of light years away. ”

“The appearance from the small telescope of the squid galaxy (a very bright center surrounded by ambiguous clouds) closely resembles one or more stars in a wreath to the nebula.”

At 100,000 light years, Messier 77 is one of the largest galaxies in the Messier catalog.

This galaxy is also one of the closest galaxies with an active galactic nucleus (AGN).

Such active galaxies are one of the brightest objects in the universe, ejecting at best, if not all, wavelengths, from gamma rays and x-rays to microwaves and radiation waves.

However, despite its status as a popular target for astronomers, the Galaxy’s accretion disk is obscure by thick clouds of dust and gas.

“The name ‘Squid Galaxy’ has only happened recently,” the astronomer said.

“The name comes from an extended filament structure that curls around the galaxy’s discs like squid tentacles.”

“The squid galaxy is a great example of how advances in technology and scientific understanding can completely change the perception of astronomical objects.

Also known as the Antarctic Crunch Squid or Giant Squid, the Giant Squid is a member of the Glass Squid Family Cranchiidae.

The species can be up to 10-14 m long and weighs up to 500-700 kg, making it the heaviest invertebrate on the planet.

Little is known about their life cycle, but in the end they lose the see-through look of the boy.

Dr. Kat Bolstad, a researcher at Auckland Institute of Technology, said:

“For 100 years, prey remains in the stomachs of whales and seabirds, and we mostly encountered them as harvested teeth predators.”

A giant squid with a long 30 cm larvae was videotaped at a depth of 600 m by a remotely operated vehicle (ROV) Subathian March 9, 2025.

“It’s incredible that we can leverage the power of taxonomic communities. R/V Falkor (Too) “The University of Essex researcher, Dr. Michelle Taylor, and the expedition chief scientist, said:

Furthermore, on January 25th, 2025, the previous team Folcole (too) Photographed by the expedition First confirmed video of Glacier glass squid (Galiteuthis glacialis) in the South Ocean near Antarctica.

Galiteuthis glacialis is another glass squid species that has never been seen lively in natural environments before.

“One of the most distinctive features of the giant squid is the presence of a hook in the center of the eight arms. Galiteuthis glacialis said Dr. Aaron Evans, an independent expert in the glass squid family.

“If not, then the boy’s giant squid and Galiteuthis glacialis It is similar, with a transparent body and sharp hook at the end of two long tentacles. ”

Dr. Jyoticavilmani, executive director of Schmidt Ocean Institute, said:

“Fortunately, we caught a high-resolution image of these creatures so that world experts who weren’t on board could identify both species.”

A Giant Squid Captured on Video for the First Time Swimming Almost 2,000 Feet Below the Ocean’s Surface

The giant squid, the world’s heaviest invertebrate, was captured in a video of itself swimming in the deep sea for the first time since it was identified a century ago.

The video was recorded on March 9th The Schmidt Ocean Institute said in a news release by an international team of scientists and crew on an expedition near the Southern Sandwich Islands in the South Atlantic.

Scientifically named Mesonychoteuthis Hamiltoni, the squid was a long-time boy nearly a foot long, the release said. It was 1,968 feet deep when scientists and crew members of the Institute’s Forcole research vessel filmed the video on a remotely operated vehicle called Subastein.

The remotely operated vehicle Subastaian will be retrieved on the research vessel Forcol.

“It’s exciting to see first in situ”We’ve been working hard to get the better of our customers,” said Kat Bolstad of Auckland Institute of Technology.

Bolstad was one of the scientific experts who helped verify the video.

“For 100 years, we mostly encountered them as harvested teeth predators, as prey remains mainly in the stomachs of whales and seabirds,” she said.

The squid was officially identified and named in 1925, but up until now, no one could have seen it lively on camera.

The squid is estimated to grow up to 23 feet long and weigh as much as 1,100 pounds, the institute said. Little is known about the life cycle, but as adults, they lose their transparent body.

A giant squid should not be confused with a giant squid. Natural History Museums in London. Both are giant cephalopods but belong to various families of squid. Giant squids have much longer tentacles, while giant squids have much larger bodies with shorter tentacles.

Bolstad and Aaron Evans, independent experts in the glass squid who helped validate the video, said the giant squid has distinctive properties, including a hook in the middle of its eight arms.

So far, ROV Subastein from the Institute has filmed the first confirmed video of at least four squid species in the wild, including last year’s Promachoteuthis and Ram’s Horn Squid in 2020.

Shark sounds captured in groundbreaking recording

Dolphin’s mouth. The whale sings. Fishcloak, chirp, Grant, ham, groans. However, in sea chatting, up until now, one voice was missing.

Sharks have long been considered quiet killers of the water. However, scientists at the University of Auckland in New Zealand recently recorded a rig shark, or Mastel Slenticratus, to create a sharp click by combining the teeth, according to findings published in the journal. Royal Society Open Science on Wednesday. They believe this is the first time a shark has actively made noise.

Chief investigator Karolyn Nieder was the first to hear the sound while studying the shark’s hearing abilities. While she was dealing with one shark, it clicked and snapped a similar sound to the sound of an electric spark, she said.

The noise came from the Rig shark, a rather small shark common in waters around New Zealand. It grows up to 5 feet and feeds mainly on crustaceans. It is eaten by larger shark species and New Zealanders who use it to make fish and chips.

Dr. Nieder was surprised when he heard the noise.

Other sea creatures have mechanisms to make noise. For example, fish have a gas-filled sac, a swimming bladder, which is used for buoyancy but can be used as a type of drum. Many fish have muscles that can vibrate the swimming bladder in a manner similar to the human vocal cords.

However, the sharks were “thought to be silent and could not actively produce sound,” Dr. Nieder said.

In this study, she and her co-authors observed the behavior of ten rig sharks housed in tanks equipped with underwater microphones. They discovered that all ten sharks begin to create click noise when they move between tanks or are held gently.

On average, the shark clicks nine times at 20-second intervals, and researchers believe they made noises by stitching the teeth together.

They didn’t make any noise while feeding or swimming, making scientists believe it is more likely to click when emphasizing or surprised, not as a way of communicating with each other.

“I think it’s likely that they’ll make those noises when they’re attacked,” Dr. Nieder said, adding that many other fish will snap their teeth and jaws to stop or distract predators.

It was unclear whether the shark could hear the clicks themselves. Did they make the sound in the wild or just get caught? And whether they intentionally made it or whether it was a side effect of their reaction to being surprised, Dr. Nieder said.

Christine Elbe, director of the Marine Science and Technology Centre at Curtin University in Australia, said the study expanded in the growing field of research into how marine animals make and hear sounds.

“Once you start watching, there are more and more species that use sounds,” she said.

So it wasn’t surprising to find that sharks could make a fuss, she said.

But she says, “I think it’s important in the sense that it completely underestimates communication between animals and environmental sensing capabilities, and also completely underestimates the way noise affects it.”

Images of Mars and Deimos captured by Hera from a moon

On March 12, 2025, Spatula – ESA’s first space safety mission – reached Deimos, coming within 5,000 km of the surface of Mars and 1,000 km from Deimos. During flybys, the spacecraft deployed scientific payloads for studying Earth and the Moon. Activating the instruments onboard Hera, scientists were able to visualize the surface of Mars and the features of Deimos.

Mars appears bright blue in this near-infrared image of the Hyperscout H Hyperspectral Imager, which was acquired on the Mission’s March 12th Gravity Assisted Flyby. The spacecraft was about 1,000 km from Deimos, 12.4 km in diameter when this image was acquired. In the background, you can observe various Mars features. At the top of the image is the bright Terra Sabaaa area near the equator of Mars, which is outlined in a dark area, with the huygen crater at a distance of 450 km to the left of the Terra Aaa at Sabaaa and the 460 km diameter Shea Parelli Crater. To the bottom right of the Mars disc is one of the largest known impact craters in the solar system, 2,300 km in diameter and over 7 km deep. Image credit: ESA.

Launched on October 7th, 2024, Hera is now en route to visit Dimorphos. Dimorphos was the first asteroid to have its orbit altered by human intervention.

By gathering detailed data on this asteroid, which was affected by NASA’s DART spacecraft in 2022, Hera aims to advance asteroid deflection into a well-understood and potentially replicable technology.

Hera’s Flyby of Mars was a crucial step in the journey through Deep Space, meticulously planned by ESA’s Flight Dynamics team.

Approaching within 5,000 km of Mars, the planet’s gravity assisted in adjusting the spacecraft’s path towards its target.

Traveling at 9 km/s relative to Mars, Hera was able to capture images of Deimos from 1,000 km away, exploring the far side of the tiny moon opposite to the red planet.

“The mission analysis and flight dynamics team at ESOC in Germany did an exceptional job in planning the gravity assist,” said Caglayan Guerbuez, ESA’s Hera Spacecraft Operations Manager.

“In particular, they had to fine-tune the operations to bring Hera closer to Deimos, which added quite a bit of extra work for them!”

Three instruments onboard HERA were utilized during the flyby.

– The asteroid framing camera of the Spara, used for navigation and scientific purposes, captured images in visible light.

– HERA’s Hyperscout H Hyperspectral Imager observed in multiple colors beyond human perception, aiding in characterizing mineral compositions with its 25 visible and near-infrared spectral bands.

– HERA’s thermal infrared imager, provided by the Japan Aerospace Exploration Agency (JAXA), revealed physical properties such as roughness, particle size distribution, and porosity, mapping surface temperatures in mid-red wavelengths.

“These instruments were previously tested before leaving Earth, but this is the first time they were utilized on a distant moon like Deimos where knowledge is limited,” said the Research Director of CNRS, Observatoire de la Côte d’Azur.

“Upon reaching Deimos, one of the HERA instruments remained idle as the others were in use. This is due to the limitation of the Cubesats, which are only activated at slower speeds when at a considerable distance from the target,” added the Research Director.

The Tarantula Nebula is captured in the deepest X-ray images ever by Chandra

The Tarantula Nebula is the most important star-forming complex in local galaxy groups, including the Milky Way, the large Magellan cloud and the Andromeda galaxy. At its heart is the highly rich young star cluster R136, which contains the most huge known stars. The stellar wind and supernova carved the tarantula nebula into an astonishing display of arcs, pillars and bubbles.



This image of Chandra shows the Tarantula Nebula. Image credits: NASA/CXC/Penn State/Townsley et al.

The Tarantula Nebula is approximately 170,000 light years away from the southern constellation of Dorado.

The nebula, also known as the NGC 2070 or 30 Dorados, is part of the large Magellan cloud.

“The Tarantula Nebula is the most powerful and large star-forming region in the local galaxy group,” says Matthew Povich, astronomers at Polytechnic University in California, and Pennsylvania State University astronomers Raysa Townsley and Patrick Brose. I said that.

“The nebulae differ from the massive star-forming regions of the Milky Way galaxy. There is no different galactic rotation to tear the complex, so it provides fuel for at least 25 million years to supply large star-forming. It lasts and grows at the confluence of two super-huge shells, reaching a starburst percentage.”

“Today, it is dominated by a central large cluster R136, 1-2 million years ago, and includes the wealthiest young star population of the local group, and the largest star included It's here.”

“In contrast to the large star-forming regions of the galaxy, the location of the large Magellan tarantula nebula provides a low metallic starburst laboratory with low absorption and well-known distances. I'll do that.”

https://www.youtube.com/watch?v=ivd_gmu9p8c

New X-ray images of the tarantula nebula contain data from the large Chandra program, including observation times of approximately 23 days, with Chandra previously performed in the nebula for over 1.3 days.

The 3,615 x-ray sources detected by Chandra include large stars, double star systems, bright stars still in the process of formation, and much smaller clusters of young stars.

The authors also identified the oldest X-ray pulsar candidate ever detected in Tarantula Nebula, PSR J0538-6902.

“There are a ton of diffuse hot gases found in x-rays that come from various sources that arise from the giant star winds and gases expelled by supernova explosions,” the astronomer said.

“This dataset is ideal for the near future to study diffuse X-ray emissions in star-forming regions.”

Team's paper It will be published in Astrophysical Journal Supplement Series.

Stunning Images of NGC 337 Captured by Hubble

The NASA/ESA Hubble Space Telescope took this photo of barred spiral galaxy NGC 337.



This Hubble image shows NGC 337, a barred spiral galaxy about 60 million light-years away in the constellation Cetus. Image credit: NASA / ESA / Hubble / C. Kilpatrick.

NGC337 It is located in the constellation Cetus, approximately 60 million light-years from Earth.

Also known as LEDA 3572 or IRAS 00573-0750, this barred spiral galaxy is 60,400 light years in diameter.

it was discovered It was discovered on September 10, 1785 by German-British astronomer William Herschel.

NGC 337 is the largest and brightest member of the NGC 337 Group (also known as LGG 15), a small group that includes at least three other galaxies.

The new images of the galaxy were created from separate exposures taken in the visible and near-infrared regions of the spectrum. Hubble’s advanced survey camera (ACS).

Two filters were used to sample different wavelengths. Color is obtained by assigning different hues to each monochromatic image associated with an individual filter.

“This image combines observations made at two wavelengths and highlights the galaxy’s golden center and blue surround,” Hubble astronomers said in a statement.

“The golden glow in the center comes from the older star, and the glowing blue edge gets its color from the young star.”

“If Hubble had observed NGC 337 about a decade ago, the telescope would have spotted something remarkable among the hot blue stars along the edge of the galaxy: a brilliant supernova,” they added. Ta.

“Labeled SN2014cxthis supernova is notable in that it was discovered almost simultaneously by two very different methods: the prolific supernova hunter Koichi Itagaki and the All-Sky Automated Supernova Surveyor (ASAS-SN). ”

“ASAS-SN is a worldwide network of robotic telescopes that scan the sky for sudden events such as supernovae.”

According to astronomers, SN 2014cx IIP type supernova.

“The Type II classification means that the star that exploded was a supergiant with a mass at least eight times that of the Sun,” the researchers said.

“The ‘P’ stands for plateau, meaning that after the light from the supernova began to dim, the level reached a plateau and remained the same brightness for weeks or months before fading further. .”

“This type of supernova occurs when a massive star can no longer generate enough energy at its core to avoid the crushing pressure of gravity.”

“The progenitor star of SN 2014cx is estimated to have been 10 times more massive and hundreds of times wider than the Sun.”

Although it has long since dimmed from its early brightness, astronomers are still monitoring the remains of SN 2014cx.

New images of Messier 83 captured by the Dark Energy Camera reveal unexpected discoveries

The spiral arm of Messier 83, one of the most prominent spiral galaxies in the night sky, exhibits a high rate of star formation, with six supernovae observed, according to astronomers at NSF’s NOIRLab.

Messier 83 is located approximately 15 million light-years away in the southern constellation Hydra.

The galaxy, also known as the Southern Pinwheel Galaxy, M83, NGC 5236, LEDA 48082, and UGCA 366, has a diameter of about 50,000 light-years, making it about twice smaller than the Milky Way.

With an apparent magnitude of 7.5, it is one of the brightest spiral galaxies in the night sky. May is the best month to observe with binoculars.

Messier 83 is oriented almost completely face-on from Earth, meaning astronomers can observe its spiral structure in great detail.

This galaxy is a prominent member of a group of galaxies known as the Centaurus A/M83 group, which also counts dusty NGC 5128 and irregular galaxy NGC 5253 as members.

It was discovered on February 23, 1752 by French astronomer Nicolas Louis de Lacaille.

“Between 1750 and 1754, the French astronomer Nicolas-Louis de Lacaille studied the night sky with the purpose of determining distances to planets,” NOIRLab astronomers said.

“During this period, he observed and cataloged 10,000 stars and identified 42 nebular objects, including Messier 83, which he discovered during an expedition to the Cape of Good Hope in 1752.”

“In 1781, Charles Messier added it to his famous catalog and described it as a ‘starless nebula’, reflecting the limited knowledge of galaxies at the time.”

“It wasn’t until the 20th century, thanks to the work of Edwin Hubble, that astronomers realized that objects like Messier 83 were actually in another galaxy far outside the Milky Way.”

New images of Messier 83 dark energy camera (DECam), mounted on NSF’s Victor M. Blanco 4-meter telescope at the Cerro Tororo Inter-American Observatory, a program of the NSF NOIRLab.

“This image shows Messier 83’s distinct spiral arms filled with clouds of pink hydrogen gas where new stars are forming,” the astronomers said.

“Interspersed between these pink regions are bright blue clusters of hot young stars whose ultraviolet radiation has blown away the surrounding gas.”

“At the center of the galaxy, a yellow central bulge is made up of old stars, and weak bars connect spiral arms through the center, funneling gas from the outer regions toward the center.”

“DECam’s high sensitivity captures Messier 83’s extended halo and the countless more distant galaxies in the background.”

“Just as Messier 83 is filled with millions of newly formed stars, this galaxy is also home to many dying stars,” they added.

“Over the past century, astronomers have witnessed a total of six stellar explosions called supernovae in Messier 83. Only two other galaxies can match this number.”

In 2006, astronomers discovered a mysterious feature at the center of Messier 83.

“At the center of this galaxy, we discovered a never-before-seen concentration of mass similar to a secondary nucleus, likely the remains of another galaxy being consumed by Messier 83 in an ongoing collision. , likely the same collision that caused the starburst activity,’ the researchers said.

“The two nuclei, which likely contain the black hole, are expected to coalesce into a single nucleus in another 60 million years.”

A photo of a star in another galaxy was captured for the first time

Left: Image of star WOH G64 taken with the Very Large Telescope Interferometer in Chile. Right: Artist’s impression of the star

ESO/K. Onaka et al., L. Calçada

Astronomers have taken the first detailed pictures of a star in another galaxy more than 160,000 light-years away. This giant star may be showing signs that it’s only a few years away from exploding, but we’ve never seen it in detail before.

The largest stars we know of are red supergiants, which are stars that have run out of hydrogen fuel in their cores. Instead, the shell of hydrogen gas surrounding the core burns, causing the star’s volume to expand significantly.

One of the largest red supergiants that we know of is WOH G64, also known as a giant star. It is 1540 to 2575 times larger than the Sun and resides in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. The star has attracted the attention of astronomers since it was discovered in the 1970s, but its distance has made it difficult to study it in detail.

now, jacko van loon and colleagues from Keele University in the UK used the Very Large Telescope Interferometer in Chile’s Atacama Desert to take close-up pictures of WOH G64. The interferometer is a collection of four individual telescopes linked together to function as if they were 200 telescopes in one. meter telescope. “In this image, you can see details similar to what you would see in an astronaut walking on the moon,” Van Loon said. “You can’t see it with a normal telescope aimed at the moon.”

The image, taken using infrared light, shows a bright ball of gas and dust, exhaled by the star and now surrounding it in a dense cocoon, at temperatures above 1,000 degrees Celsius (1,832 degrees Fahrenheit). “This is a structure that we really didn’t expect to see,” Van Loon said. “We expected to have a star in the middle.”

The star appears dimmer than when it was last observed, so the gas and dust likely appeared relatively recently, Van Loon said. It may have been created by a star blowing away its outer layers, and astronomers have never seen it in a red supergiant.

If that happens, and the process is similar to that seen in similar stars called blue supergiants, it could be a sign that the star will take decades or even years to explode. I don’t know. “If we can watch this star explode, we will be able to learn much more about the star before it explodes,” Van Loon said.

“Being able to reconstruct an image of this object at such a great distance is technically quite impressive,” he says. paul krauser At the University of Sheffield, UK.

But it’s difficult to say with certainty whether the observed gases and dust, and the accompanying dimming of the brightness, are signs of an impending explosion. “Stars like this object are well known to be highly volatile,” Krauser said. “It’s simply what happens in these objects where there’s a dense, slow outflow that doesn’t go very far from the star. They’re well known to be dust factories.”

League of Legends finals: A showcase of unmatched talent and pure joy captured in a button push

GGiven the influx of bad news from the gaming industry over the past 10 months, it’s no surprise that this weekend, sitting in a crowd of 20,000 happy and passionate fans, the biggest event on the esports calendar, The League Being able to watch the Of Legends World Championship was somewhat reassuring. Finals. The event, held at London’s O2 Arena, was the culmination of a five-week global competition to discover the world’s best teams. Having never been to one before, I had no idea what to expect, mainly because the finals are usually held in Asia, where the best players usually gather. Can we track what’s going on? Would you care? The answers to these questions were “fairly well” and “well, yeah.”


For the uninitiated, League of Legends is a multiplayer online battle arena game (Moba for short) in which two teams of five players choose a warrior from a pool of 170 warriors to destroy their opponent’s home base. Fight to control the fantasy-themed map. . The arena is divided into three lanes, with an area known as the jungle in the middle, and similar to traditional team sports, each team member patrols their own specific section. Adding to the complexity is the fact that every champion character has unique skills, weapons, and magical attacks, and throughout the game you must defeat monsters and dragons to earn experience points that make you more powerful. Masu. It’s both a deep strategy game and a tremendous riot of stomping warriors, galloping horsemen, and hovering wizards.

This year’s final was between experienced Korean team T1 and Chinese newcomer team Bilibili Gaming (abbreviated as BLG). The latter had gained momentum by defeating local rival Weibo Gaming in the semi-finals, but T1 was the firm favorite to win the tournament having already won four times. They were almost eliminated from the competition early on, but they seem to have a habit of getting back into it the moment everyone quits. At the arena, I managed to get a seat next to James Lynch of the esports news site dexerto volunteer to tell me about the action. He describes T1 as the League of Legends equivalent of the 1974 Netherlands World Cup team. Free-spirited, unconventional, and full of neurotic genius. Lee “Faker” Sang-hyuk is widely considered to be the greatest player in league history, and at the center of it all is the master Johan Cruyff. “His movements are very strange and unpredictable,” Lynch says. “It’s very difficult to kill him.”

Before the finals begin, there will be a 10-minute mini-concert featuring American rappers Ashnikko and Linkin Park, complete with fireworks, giant LED displays and incredible art direction from dozens of dancers. The whole thing has the feel of a major sporting event mixed with live K-Pop, a riot of color, passion, and performing arts. In the hours leading up to the finals, fans flocked to the venue to purchase original merchandise, meet friends from the community and, of course, dress up as their favorite League of Legends characters.

It turns out I was extremely lucky that this was my debut watching League of Legends. It’s an exciting encounter. Once the showdown begins, the best-of-five format is pushed to its limits, with the two teams taking turns killing each other for the first four games. Throughout the finals, Faker is a formidable playmaker, continually jumping into skirmishes, taking out opponents, and managing to escape with only a millimeter of health left. In the arena, 10 young players can be seen competing on a giant screen suspended above the stage. These displays draw us in rather than taking us out of the game. The crowd of mostly 20 fans loudly applauds the smart move and chants as their team gains the upper hand.

The showdown was a deliberate affair, with warriors gingerly roaming the map, poking and prodding at each other. Eventually, the whole thing explodes into a massive clash, making the battle between the Bastards look like a mini-brawl outside a kebab shop.

T1 was victorious, but it was also a victory for the entire concept of esports. The scene has struggled to live up to its 2010s hype, at least financially. At the time, the team’s overestimated global value attracted large investors and sponsors, which led to a bloated team organization and soaring salaries for star players. Last year saw many organizations, events, and tournaments shut down, including Activision Blizzard’s much-hyped Overwatch League. But this weekend’s event drew a peak audience of 6.94 million viewers, most of whom watched from home on streaming platforms like Twitch and YouTube, setting a new record for esports.

It’s easy to think of video games as an industry rather than a culture that brings joy to people. Sometimes it’s more than just sales or viewership, it’s about sitting in an arena with 20,000 adoring fans. Outside the O2 Megaplex, I spoke to Morgan, an attendee perfectly dressed as Aphelios (or, more accurately, in his Heartsteel costume). He explained the appeal as follows: But he’s very friendly. Also, there are so many different communities in the league, and it’s great to see them come together and bond over something they have in common and one thing they’re really passionate about. That’s what’s really beautiful about this work.

Stunning Galaxy Duo Captured by NASA Telescope

NASA has released a beautiful composite image of two overlapping spiral galaxy pairs, IC 2163 and NGC 2207, taken by the NASA/ESA Hubble Space Telescope and the NASA/ESA/CSA James Webb Space Telescope.

This composite image shows the galaxies IC 2163 (left) and NGC 2207 (right). Image credit: NASA/ESA/CSA/STScI.

of IC 2163-NGC 2207 pair It is located about 114 million light years from us in the direction of the constellation Canis Major.

The large and massive galaxy is registered as NGC 2207, and the smaller galaxy is registered as IC 2163.

Strong tidal forces from the former distorted the shape of the latter, blowing stars and gas into long streams stretching 100,000 light years.

IC 2163 made its closest approach 40 million years ago, passing NGC 2207 in a counterclockwise direction.

However, IC 2163 does not have enough energy to escape NGC 2207's gravity and is doomed to be pulled back again in the future, passing by the larger galaxy.

“The pair's eerie colors represent a combination of mid-infrared light from the web and visible and ultraviolet light from Hubble,” NASA astronomers said.

“Look for potential evidence of their light scrapes on impact surfaces where material from galaxies may have collided.”

“These lines, rendered in bright red, including the eyelids, may be responsible for the appearance of the galaxy's bulging, vein-like arms.”

“The galaxy's first passage may also have distorted its delicately curved arms and elicited tidal extensions in some places.”

“The small diffused spiral arm between IC 2163's core and its leftmost arm may be an example of this activity.”

“More tendrils appear to be hanging between the galactic cores.”

“Another extension drifts off the top of the larger galaxy, forming a thin translucent arm that essentially extends out of the picture.”

These images show two overlapping spiral galaxies, IC 2163 and NGC 2207. On the left is Hubble's ultraviolet and visible light observations, and on the right is Webb's mid-infrared observations. Image credit: NASA/ESA/CSA/STScI.

IC 2163 and NGC 2207 form stars at such high rates that they appear to have millions of individual hearts flapping across their arms.

These galaxies produce the equivalent of 20 solar-mass stars of new solar-mass stars every year.

“Our Milky Way galaxy only forms two to three new Sun-like stars a year,” the astronomers said.

“Both galaxies have experienced seven known supernovae in recent decades, compared to the Milky Way's average of once every 50 years.”

“Each supernova may have removed space within the arms, rearranging gas and dust that later cooled, allowing many new stars to form.”

“To identify sequences of star-forming activity, look for the bright blue regions seen by Hubble in ultraviolet light and the pink and white regions detailed primarily by Webb's mid-infrared data.” the researchers said.

“Stars in larger regions are known as superclusters.”

“Look for examples of these in the top spiral arms that wrap around larger galaxies and point to the left.”

“Other bright regions of the galaxy are ministarbursts, where many stars form in quick succession.”

“In addition, the upper and lower 'eyelids' of IC 2163, the small galaxy on the left, are filled with newer star formation and are burning brighter.”

New Images of Comet Gassan-ATLAS Captured by NASA Astronauts and SOHO Spacecraft

A bright comet from the Oort cloud named C/2023 A3 (Tsuchinshan-ATLAS) is passing close to Earth and will be visible until late October 2024.

This image, taken by the ESA/NASA Solar-Heliospheric Observatory (SOHO) on October 10, 2024, shows Comet Atlas Gassan and its bright tail streaming from upper left to right. Mercury will be visible as a bright dot on the left. Image credit: ESA/NASA.

Comet Tsuchiyama-ATLAS It was discovered on January 9, 2023 by astronomers from China's Zishan Observatory.

The comet, also known as C/2023 A3, was independently discovered by South Africa's ATLAS on February 22, 2023.

It orbits the Sun in a retrograde orbit and lies at an inclination of 139°.

It reached perihelion on September 27, 2024, at a distance of 0.391 astronomical units. Its closest approach to Earth was on October 12th. It is expected to be 200 AU from the Sun in 2239.

Each day throughout October, the comet rises higher and higher in the western sky as it moves away from the sun. But as it progresses, it gets darker and darker.

October 14th to 24th is the best time to observe it using binoculars or a small telescope.

Eagle-eyed skywatchers may be able to spot the star with their naked eyes for a few days, but then binoculars or a telescope will be needed as it gets darker.

“Comet Tuchinshan-Atlas may have come from the Oort Cloud, a region of space between 2,000 times the distance between Earth and the Sun and one light year.” said Jason Ybarra, director of the WVU Planetarium and Observatory.

“This region is so far away that the gravitational pull from the Sun competes with the gravitational pull from passing stars and the entire Milky Way galaxy.”

NASA astronaut Matthew Dominick took this photo of comet Atlas Tsuchiyama on September 28, 2024. At the time, the comet was about 70.8 million kilometers (44 million miles) from Earth. Image credit: NASA/Matthew Dominick.

“The larger the orbit, the longer it takes for the comet to orbit that orbit,” he added.

“In the case of comets originating from the Oort cloud, their orbits take a very long time, so their orbits may change due to gravitational interactions with other bodies in the solar system, and it is possible to predict the future behavior of comets. It becomes difficult to do so.”

“If it gains enough energy from these interactions, Comet Gassan-ATLAS may never come back. It will have to wait at least another 80,000 years. In any case, it will be a once-in-a-lifetime event. It’s an event.”

Just before sunrise on September 28, NASA astronaut Matthew Dominick took a time-lapse photo of the comet Tuchingshan Atlas orbiting over the South Pacific Ocean southeast of New Zealand from the International Space Station.

From October 7th to October 11th, the comet brightly illuminated the field of view of the onboard LASCO (Large Angle Spectroscopic Coronagraph Experiment) instrument. ESA/NASA Solar Heliosphere Observatory (Soho).

This device uses a disc to block the sun's bright light, making it easier to see details and objects near the sun.

New and surprising images of Messier 90 captured by Hubble

Astronomers using the NASA/ESA Hubble Space Telescope have obtained a surprising new perspective of the intermediate spiral galaxy Messier 90.

This Hubble image shows Messier 90, an intermediate spiral galaxy located 53.8 million light-years away in the constellation Virgo. Image credits: NASA / ESA / Hubble / D. Tilker / J. Lee / PHANGS-HST team.

Messier 90 is located approximately 53.8 million light years away in the constellation Virgo.

This spiral galaxy, also known as M90 or NGC 4569, was discovered by French astronomer Charles Messier on March 18, 1781.

Messier 90 is the brightest member of this bunch. Virgo Cluster is a group of about 1,300, sometimes up to 2,000 galaxies.

This galaxy is remarkable, as it is one of the few galaxies that appear to be moving toward the Milky Way, rather than away from it.

“In 2019, images of Messier 90 Hubble's Wide Field and Planetary Camera 2 (WFPC2) was imaged in 1994, shortly after the camera was installed,” Hubble astronomers said in a statement.

“That image has a distinctive stair-step pattern due to the layout of WFPC2's sensor.”

“WFPC2 was replaced in 2010. wide field camera 3 (WFC3),” they added.

“Hubble used WFC3 in 2019 and again in 2023 when it switched caliber to Messier 90.”

“We processed the resulting data to create this surprising new image, providing a more detailed view of the galaxy's dusty disk, gaseous halo, and bright center.”

“The inner region of the Messier-90 disk is a site of star formation, highlighted here by red H-alpha light from the nebula, which is absent in other parts of the galaxy,” the astronomers said.

“Messier 90 is located within a relatively nearby galaxy in the Virgo cluster, and its orbit followed an orbit close to the cluster's center about 300 million years ago.”

“The gas density in the inner cluster weighed down on Messier 90 like a strong headwind, stripping enormous amounts of gas from the galaxy and creating the diffuse halo we see here around the galaxy.”

“This gas will no longer be available for Messier 90 to form new stars, resulting in its eventual demise as a spiral galaxy.”

“Its trajectory through the Virgo Cluster has accelerated so much that it is on the verge of escaping the cluster altogether, and coincidentally it is moving in our direction. Other galaxies in the Virgo Cluster are also moving in our direction. They have been measured at similar speeds, but in opposite directions.''

“Over billions of years to come, we will get a better view of Messier 90 as it evolves into a lenticular galaxy.”

New Images of UGC 4879 Captured by Hubble Space Telescope

Hubble astronomers have released a stunning new image of the dwarf irregular galaxy UGC 4879, taken by the NASA/ESA Hubble Space Telescope.

This Hubble Space Telescope image shows irregular dwarf galaxy UGC 4879, about 3.6 million light-years away in the constellation Ursa Major. Image credit: NASA / ESA / Hubble Space Telescope / K. Chiboucas, NOIRLab and Gemini North / M. Monelli, Canarian Astrophysics Institute / Gladys Kober, NASA and Catholic University.

UGC 4879 is an irregular dwarf galaxy in the constellation Ursa Major.

Also known as VV124 and LEDA 26142, this galaxy is quite isolated.

It lies 3.6 million light years from our Milky Way galaxy and 3.9 million light years from the Andromeda galaxy.

Dwarf galaxy Leo A, located about 1.6 million light-years away, is UGC 4879's closest neighbor.

This isolation makes UGC 4879 an ideal laboratory to study primordial star formation, without the complications of interactions with other galaxies.

There are only two other galaxies in the Local Group that have a similar, though slightly lower, isolation to UGC 4879: DDO 210 and SgrDIG, which are located in the opposite direction from UGC 4879.

“UGC 4879 is an isolated dwarf galaxy that lies just outside our Local Group of galaxies,” Hubble astronomers said in a statement.

“Because of its isolation, we are studying UGC 4879 to determine whether it is an old, relatively undisturbed galaxy.”

“Theories suggest that the least massive dwarf galaxies may have formed first.”

“If UGC 4879 is a relic from the early universe, it may offer clues about the hierarchy and evolution of galaxies, galaxy clusters, and even the universe itself.”

This image of UGC 4879 combines data from two Hubble observing programs focused on learning more about how dwarf galaxies form and evolve.

New Images of Arp 142 Captured by Webb Show Stunning Detail

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have captured new infrared images of two interacting galaxies. Alp 142.



This Webb image shows two interacting galaxies known as Arp 142. On the left is NGC 2937, nicknamed “The Egg” because of its appearance, and on the right is NGC 2936, nicknamed “The Penguin” because of its appearance. Image courtesy of NASA/ESA/CSA/Webb/STScI.

The interacting pair, Arp 142, is located about 326 million light-years away in the southern constellation Hydra.

This system is ARP Catalog of Peculiar Galaxies It was observed by astronomer Halton C. Earp in the 1960s.

It contains the star-forming spiral galaxy NGC 2936 and its elliptical companion galaxy NGC 2937 at the lower left, which bears a striking resemblance to a penguin guarding its eggs.

The “penguin” part of the pair, NGC 2936, was probably once a relatively ordinary-looking spiral galaxy – flat like a pancake, with smoothly symmetrical spiral arms.

Because of the abundance of newly formed, hot stars, its shape is twisted and distorted by the gravitational forces of nearby stars.

The twin “egg,” NGC 2937, is a collection of much older stars and, in contrast, is largely featureless.

The absence of glowing red dust features indicates that it long ago lost its reservoir of gas and dust from which new stars could form.

“The two asteroids first came close to each other between 25 million and 75 million years ago, triggering 'fireworks' – the formation of new stars – in the constellation of Penguin,” astronomer Webb said in a statement.

“In the most extreme cases, galaxy mergers could result in the formation of thousands of new stars every year for millions of years.”

“In the case of penguins, studies have found that they form around 100-200 stars per year. By comparison, in our own Milky Way galaxy (which is not interacting with a galaxy of a similar size), around six to seven new stars form per year.”

“This gravitational rocking also changed the penguins' appearance,” they noted.

“The spiral arms uncoiled, pulling gas and dust in different directions like confetti.”

“When galaxies interact, it's rare for individual stars to collide (the universe is huge), but the intermingling of galaxies disrupts the orbits of stars.”

“Currently, the centre of the Penguin's galaxy looks like an eye inside its head, and the galaxy has a prominent star trail in the shape of a beak, spine and fanned-out tail. A faint but noticeable dust ribbon stretches from the beak to the tail.”

“Although the Penguin Galaxy appears much larger than the Egg Galaxy, the two galaxies have roughly the same mass,” the astronomers said.

“This is one of the reasons why the tiny looking egg hasn't merged with the penguin yet.”

“Because the elliptical egg is filled with old stars and contains very little gas or dust, it doesn't emit its own 'streams' or tidal tails, and instead maintains its compact elliptical shape.”

“If you look closely, the Egg has four noticeable diffraction spikes – it's glowing because of a high concentration of stars from the galaxy.”

“Now, find the bright, edge-on galaxy in the upper right. It may look like it's crashing the party, but it’s not close by.”

Cataloging No. 1237172It lies nearly 100 million light-years from Earth. It is relatively young and not covered by dust, making it virtually invisible in Webb's mid-infrared images.”

Video captured of Blue whale mother nursing her calf for the first time

The first ever video footage of a blue whale nursing a calf was captured by a snorkeler in East Timor, Southeast Asia, and has been released.

“It’s certainly not a newborn calf.” Karen Edivain “But they’re clearly still drinking milk,” said the researcher, from the Australian National University in Darwin.

Edibane says capturing the footage is an incredible feat that has never been achieved before. The action was captured on camera by a snorkeler on an ecotourism voyage swimming with the pygmy whales off the coast of the capital, Dili, in 2022, and has only now been made public.

Blue Whale (Mushibaga) is the largest known animal to have ever lived on Earth, sometimes reaching lengths of over 30 meters and weighing nearly 200 tons.Southern wolfThe sharks found off the coast of Timor-Leste are slightly smaller, reaching a maximum length of 24 metres.

Blue whale calves do not attach to their mothers when feeding, but rather release oily milk into the water, which the calf swallows.

Edivain said the large calf seen feeding in the video is probably in its second year of living with its mother — blue whales are weaned at three years.

Other significant blue whale behaviours have been sighted and filmed in the area as part of the decade-long study. Citizen Science Projects Project leader Edivine said a database of 2,700 pygmy blue whales had been compiled since 2014 and that Timor-Leste may be a base for one of the world’s largest migrations of pygmy blue whales.

Newborn calves, courtship behaviour, pre-mating behaviour and feeding behaviour have all been observed.

“We haven’t seen a penis yet, but we’ve seen very affectionate adults having a lot of fun playing with each other,” Edivain said.

Caprivec The head of marine life conservation for the Western Australian Water Environment Regulatory Authority said that until recently no one knew how many blue whales were migrating off the coast of Timor-Leste.

Beck says he was incredibly lucky to capture the footage. Blue whales are often found far offshore, in hard-to-reach locations. “It’s incredibly rare to even be in the water with a blue whale, and even rarer to be in the water at the right time and place to film a calf nursing.”

Stunning images of NGC 4689 captured by Hubble

Astronomers using the NASA/ESA Hubble Space Telescope have captured sharp images of NGC 4689, a jewel-bright spiral galaxy in the constellation Coma.



This Hubble image shows spiral galaxy NGC 4689 located 52 million light-years away in the constellation of Coma. Image credits: NASA / ESA / Hubble / D. Tilker / J. Lee / PHANGS-HST Team.

NGC 4689 It is located approximately 52 million light-years away in the constellation Kamina.

“Of the 88 constellations officially recognized by the International Astronomical Union (IAU), Coma has the distinction of being the only constellation named after a historical figure. Queen Berenice II of Egypt” explained the Hubble astronomer.

“The Latin word ‘coma’ refers to her hair, meaning that NGC 4689 can be said to be present in the Queen’s hair.”

“Some of Berenice’s contemporaries may have meant this quite literally; her court astronomer believed that Berenice’s lost locks had been destroyed by God (“among the stars”). It was given this name because there is a story that it was thought to have been placed in It is the constellation of Coma. ”

NGC 4689 is discovered It was proposed by German-born British astronomer William Herschel on April 12, 1784.

Also known as LEDA 43186 or UGC 7965, this galaxy is a member of the Virgo Cluster, a group of more than 2,000 galaxies.

NGC 4689 is tilted 36 degrees and can be viewed almost head-on.

The new images of the galaxy were created from separate exposures taken in the ultraviolet, visible, and near-infrared spectral regions. Hubble’s Wide Field Camera 3 (WFC3).

This is based on data obtained through a gender filter. Color is obtained by assigning different hues to each monochromatic image associated with an individual filter.

“This image was created using two sets of observations taken in 2019 and 2024, both as part of a program to observe multiple ‘nearby’ galaxies.” Astronomy said the people.

The 2024 observing program is an interesting example of how Hubble, a relatively old but highly productive telescope, can support the work of the technologically cutting-edge Webb Telescope. ”

“Observations collected by Webb change our understanding of how galaxies change and evolve over time by providing data of unprecedented detail and clarity. It will be.”

“But thanks to their complementary capabilities, new observations from Hubble (such as those used to create new images) can aid the work being done using the Web.”

“In this case, the Hubble data were collected to better understand the stellar populations of nearby galaxies, which is critical to understanding the evolution of galaxies.”

“NGC 4689 therefore plays an important role in advancing our understanding of how all galaxies evolve.”

Stunning images of small spiral galaxies captured by Hubble

Astronomers using the NASA/ESA Hubble Space Telescope have captured an excellent image of the spiral galaxy ESO 422-41 in the constellation Columba.

This Hubble image shows ESO 422-41, a spiral galaxy located in the constellation Columba, about 34 million light-years away. Image credit: NASA / ESA / Hubble / C. Kilpatrick.

ESO 422-41 It is located in the constellation Columba, about 34 million light years away.

DDO 230, LEDA 16864, or UGCA 103, the diameter of this spiral galaxy is 30,000 light years.

“The name ESO 422-41 comes from its appearance in the European Southern Observatory (B) Atlas of the Southern Sky,” Hubble astronomers said.

“In the era before automated sky surveys by space observatories such as ESA's Gaia satellite, large-scale photographic surveys discovered many stars, galaxies, and nebulae.”

“Astronomers used the then most advanced large telescopes to create hundreds of photographs covering parts of the sky.”

“They then studied the resulting photographs and attempted to catalog all the new objects revealed.”

“In the 1970s, a new telescope at ESO's La Silla facility in Chile probed the southern sky, which had not yet been explored as deeply as the northern sky,” they added.

“At that time, the primary technology for recording images was glass plates treated with chemicals.”

“The resulting collection of photographic plates became the ESO (B) Atlas of the Southern Sky.”

“Astronomers from ESO and Uppsala, Sweden, worked together to study the plates and recorded hundreds of galaxies (ESO 422-41 is just one of them), star clusters and nebulae. I was a beginner.”

“Since then, astronomical sky surveys have progressed from digital, computer-aided surveys such as the Sloan Digital Sky Survey (SDSS) and Legacy Survey to surveys performed by space telescopes such as Gaia and the Wide-Field Infrared Survey Explorer (WISE). It has transitioned to

“Nonetheless, photographic sky surveys have made significant contributions to astronomical knowledge over the decades, and the glass plate archive serves as an important historical reference for a wide range of skies. .”

“Some of them are still actively used, for example, to study variable stars over time,” the researchers pointed out.

“And the objects revealed by these surveys, including ESO 422-41, can now be studied in detail with telescopes like Hubble.”

The new images of ESO 422-41 consist of observations from Hubble's advanced survey camera (ACS) in the near-infrared and optical portions of the spectrum.

Two filters were used to sample different wavelengths. Color is obtained by assigning different hues to each monochromatic image associated with an individual filter.

Close-Up View of Io’s Unique Features Captured by NASA’s Juno Mission

In December 2023 and February 2024, NASA’s Juno spacecraft will fly extremely close to Jupiter’s volcanic moon Io, coming within about 1,500 kilometers (930 miles) of the surface and obtaining the first close-up images of the moon’s northern latitudes. Planetary scientists have now turned images collected during the flight into animations that show two of Io’s most dramatic features: its mountains and a nearly glassy rock formed by cooling lava called Loki Patera. It emphasized the smooth lake.

The JunoCam instrument aboard NASA’s Juno spacecraft imaged Io, the most geologically active object in the solar system, on February 3, 2024, from a distance of approximately 7,904 km (4,911 miles) . Image credit: NASA/SwRI/MSSS.

“There are only a few scattered volcanoes on the island of Io, and we captured some of them active,” said Juno principal investigator and Southwest Research Institute cosmologist. said Scott Bolton, director of science and engineering.

“We also obtained great close-ups and other data about a 200 km (127 mile) long lava lake called Loki Patera.”

“It shows in amazing detail how these crazy islands are embedded in the middle of a potential magma lake fringed with hot lava.”

“The specular reflections that our instruments record about the lake suggest that parts of Io’s surface are glass-smooth, reminiscent of the obsidian glass produced in volcanoes on Earth. “

Map generated using data collected by Juno microwave radiometer (MWR)’s instruments revealed that Io not only has a relatively smooth surface compared to Jupiter’s other Galilean moons, but also has poles that are colder than the mid-latitudes.

During Juno’s long-term mission, the spacecraft will fly closer to Jupiter’s north pole with each pass.

This change in direction allows the MWR instrument to improve the resolution of Jupiter’s polar cyclones.

This data allows us to compare multiple wavelengths at the poles and reveals that not all polar cyclones are created equal.

“Perhaps the most striking example of this difference is seen in the central cyclone at Jupiter’s north pole,” said Dr. Steve Levin, Juno project scientist and researcher at NASA’s Jet Propulsion Laboratory. states.

“Although clearly visible in both infrared and visible light images, the microwave signature is not as strong as other nearby storms.”

“This indicates that its subsurface structure must be very different from other cyclones.”

“As the MWR team continues to collect more and better microwave data in every orbit, we expect to develop more detailed 3D maps of these interesting polar storms.”

Young multi-star system captured in stunning Hubble Space Telescope photos

A new image from the NASA/ESA Hubble Space Telescope shows a jet emerging from the cocoon of the multistar system FS Tau.



This Hubble image shows the multistar system FS Tau about 450 light-years away in the constellation Taurus. Image credit: NASA / ESA / K. Stapelfeldt, NASA Jet Propulsion Laboratory / Gladys Kober, NASA / Catholic University.

FS Tau It is located about 450 light years away in the constellation Taurus.

The system is part of the Taurus-Auriga region, a collection of dark molecular clouds that is home to many newly formed young stars.

FS Tau, also known as HH 157 or TIC 58437437, is only about 2.8 million years old, making it an extremely young star system.

FS Tau is a multi-star system consisting of FS Tau A, a bright star-like object near the center of the image, and FS Tau B, a bright object on the far right hidden by a dark vertical dust lane. ''' said the Hubble astronomer.

“The young object is surrounded by gently illuminated gas and dust in this stellar nursery.”

“FS Tau B is a protostar surrounded by a protoplanetary disk. A protoplanetary disk is a pancake-like collection of dust and gas left over from star formation that eventually coalesces to form a planet. It will be.”

“A thick lane of dust seen almost head-on separates what is believed to be the illuminated surface of the flared disk.”

“FS Tau B is probably T TauriAlthough nuclear fusion has not yet begun, it is a type of young variable star that is beginning to evolve into a hydrogen-fueled star similar to the Sun. ”

“Protostars glow because of the thermal energy released when the gas clouds from which they formed collapse, and from the accretion of material from nearby gas and dust.”

“Variable stars are a type of star whose brightness changes significantly over time.”

“FS Tau A itself is a Tauri T binary system, consisting of two stars orbiting each other,” the researchers added.

“Protostars are known to emit fast-moving columns of energetic material called jets, and FS Tau B provides a striking example of this phenomenon.”

“Protostars are the source of the unusual, asymmetric, double-sided jets that appear blue here.”

“Their asymmetric structure may be due to differences in the rate at which mass is ejected from the object.”

“FS Tau B is Herbig halo object,” they said.

“Herbig halo objects form when jets of ionized gas emitted by young stars collide at high speed with nearby clouds of gas and dust, forming bright nebular patches.”

Stunning Shot of Spider Galaxy Captured by Hubble Space Telescope

New photos from the NASA/ESA Hubble Space Telescope show nearby irregular galaxy UGC 5829, also known as the Spider Galaxy.

This Hubble image shows UGC 5829, an irregular galaxy located approximately 30 million light-years away in the constellation Sera. Image credits: NASA / ESA / Hubble / R. Tully / M. Messa.

UGC 5829 It is located approximately 30 million light-years away in the constellation Serra.

“Although this relatively faint galaxy has not been observed very often, it has the characteristic soubliquet of a spider galaxy,” Hubble astronomers said in a statement.

“Perhaps the distorted galactic arms with glowing tips that form stars remind us of the clawed legs of arachnids.”

“Somewhat confusingly, there is another galaxy known as the Spiderweb galaxy that has a very similar nickname but is otherwise completely separate.”

“Despite the fact that this galaxy is about 300 times further away from Earth than the Spider Galaxy, it has been imaged more extensively.”

“Fortunately, the ability to accurately identify galaxies does not depend on chance names.”

“Rather, known galaxies are recorded in at least one catalog, such as the Uppsala Galaxy Catalog, and are often recorded in multiple catalogs. It has been given a name.”

“This same galaxy has been given several different names in various other catalogs,” they added.

“For example, LEDA 31923 in the Lyon-Meudon Extragalactic Database; MCG+06-24-006 in the Galactic Morphology Catalog; and SDSS J104242.78+342657.3 in the Sloan Digital Sky Survey Catalog.

“Spiderweb galaxies are not all recorded in the same catalog; each catalog is necessarily limited in scope. However, they are included in the LEDA catalog as LEDA 2826829.”

“It's clearly easier to avoid confusing the boring but unique names LEDA 31923 and LEDA 2826829 than the interesting but easily confused names Spider and Spiderweb.”

The new image of UGC 5829 consists of observations from. Hubble's advanced survey camera (ACS) and wide field camera 3 (WFC3) Found in the near-infrared and optical portions of the spectrum.

This is based on data obtained through four filters. Color is obtained by assigning different hues to each monochromatic image associated with an individual filter.

New Stunning Images of Jupiter Captured by Hubble Space Telescope

The new Hubble images taken on January 5 and 6, 2024 show many large storms and small white clouds in Jupiter’s atmosphere, indicating a lot of activity.

Jupiter’s colorful clouds create a constantly changing display of shapes and colors in its atmosphere.

The planet experiences various stormy weather patterns, including low-pressure systems, high-pressure systems, wind shear, and the Great Red Spot, the largest storm in the solar system.

Jupiter is covered by a cloud of ammonia ice crystals, about 48 km thick in an atmosphere that is tens of thousands of kilometers deep, resulting in the planet’s distinctive stripes.

The banding effect is caused by air moving at different latitudes and speeds of up to 563 km per hour.

The zones, where the atmosphere rises, are brightly colored, while the belts, where the air falls, are darker. Storms and turbulence occur when these opposing flows interact.

Hubble continues to monitor Jupiter and other exoplanets annually through the Outer Planet Atmosphere Legacy (OPAL) Program.

“The left Hubble image shows the iconic Great Red Spot prominently in Jupiter’s atmosphere,” stated Hubble astronomers.

“To the lower right is a feature known as Red Spot Junior, a high-pressure system resulting from storms in previous years.”

“This year, it appears to be turning red again, possibly due to compounds like sulfur and phosphorus.”

“In the right image, storm activity is visible in the opposite hemisphere, with two distinct storm systems rotating in opposite directions.”

These storms are expected to pass each other as they repel through their rotations.

“The presence of many storms and clouds in Jupiter’s atmosphere indicates a high level of activity,” said Dr. Amy Simon, OPAL project leader and astronomer at NASA Goddard Space Flight Center.

“Despite its small size, Jupiter’s moon Io shows volcanic activity, visible through Hubble’s sensitivity to blue and violet wavelengths.”

of Bella supernova remnantVela SNR for short, is one of the most well-studied supernova remnants in the sky and one of the closest supernova remnants to Earth.

Its progenitor star exploded 11,000 to 12,300 years ago south of the constellation Vore.

The association of this supernova remnant with the bella pulsar, made by Australian astronomers in 1968, provided direct observational evidence that supernovae form neutron stars.

“When this star exploded 11,000 years ago, its outer layer was violently stripped away and splattered around, creating a shock wave that can still be seen today,” the astronomers said in a statement.

“As the shock wave spreads into the surrounding region, hot, energetic gas flies away from the point of explosion, becomes compressed and interacts with the interstellar medium, producing the blue and yellow thread-like filaments seen in the image. .”

“Vela SNR is a gigantic structure, almost 100 light-years long and 20 times the diameter of a full moon in the night sky.”

“Although the star's final moments were dramatic, he did not completely disappear.”

“After the outer layers were shed, the star's core collapsed into a neutron star, an ultra-dense ball of protons and electrons that collided with each other to form neutrons.”

“The neutron star, named Bela pulsar, is now a supercondensed object containing the mass of a Sun-like star in a sphere just a few kilometers in diameter.”

“The Bela pulsar, located in the lower left region of this image, is a relatively faint star and indistinguishable from the thousands of objects next to it.”

Vela SNR's new image is the largest DECam image ever published, containing an astonishing 1.3 gigapixels.

“The striking reds, yellows, and blues in this image were achieved by using three DECam filters, each collecting a specific color of light,” the researchers said.

“Separate images were taken with each filter and stacked on top of each other to produce this high-resolution color image showing the intricate web-like filaments snaking throughout the expanding gas cloud.”

First sighting of Asian elephant burying carcass captured

Elephant pulling a dead calf in a tea plantation in northern Bengal, India

Parveen Kaswan and Akashdeep Roy

Asian elephants intentionally burying the bodies of their calves has been documented in the first scientific report of such behavior in this species.

Five calves were found buried in a drainage ditch on a tea plantation in the northern state of Bengal, India, with their feet and legs sticking out of the ground.

Footprints and scat of various sizes indicate that members of the herd of all ages contributed to each burial. A night watchman at the complex reported hearing loud elephant cries, sometimes lasting 30 to 40 minutes, before the herd left the area.

Akashdeep Roy Researchers at the Indian Institute of Science Education and Research in Pune and Parveen Kaswan from the Indian Forest Service suggest that the sound of these bugles may represent mourning, and that during burials the herds are “helping and caring”. It suggests that the person exhibited a certain behavior.

“The burial of a calf is an extremely rare event in nature,” says Roy.

They were surprised to find the calf buried foot-deep, but if the herd had buried each calf together, this would be the most accessible position to place the carcass in the drain. , says Roy. For elephants, who are social animals, burying their calves' heads may be the most important thing they do, he says.

The calf's body was later exhumed and examined. Their ages ranged from three months to one year old, and many were malnourished and suffering from infections. Bruises along each calf's back suggest that they were dragged or carried long distances to the burial site.

African bush elephant (african loxodonta) have been observed covering carcasses with plants and returning to the location later. However, the Asian elephant (maximum elephas) In this study, we typically avoided returning to the burial site and used an alternative route instead.

“These observations provide impressive evidence of the social complexity of elephants,” he says. Chase LaDue At the Oklahoma City Zoo and Botanical Garden. “Some people have suggested that elephants seem to behave in a unique way towards their deceased relatives. [but] This paper is the first to describe what appears to be a methodical and planned burial of an elephant calf after it was taken to a burial site. ”

Still, Professor Radu said: “We must be careful how we interpret these results, especially since the mental and emotional lives of elephants remain largely a mystery to us.” There is.

He is not convinced that the position of the calf was intentional. “I could imagine an elephant pushing a dead calf into a narrow ditch, and given its awkward shape and weight distribution, the calf would land on its back with its legs in the air,” he says. “And because the depth of the trench is shallow, the feet are not buried, but this is not due to intentional burying of the head, but due to the unique topography of the burial site.”

The land where elephants once roamed freely is shrinking as humans expand, especially in India, the world's most populous country. Only about 22 percent of the land used by elephants is within protected areas.

“Understanding how elephants behave and respond to rapid changes in human-dominated landscapes may help develop conservation strategies that promote human-elephant coexistence.” Mr. Radu says.

First-ever photograph of a majestic yellow ibis bird captured

First photo of Kijimozu

Matt Brady/University of Texas at El Paso

A rare bird with a spectacular yellow crown has been photographed for the first time in the tropical mountains of the Democratic Republic of Congo, almost 20 years after it was last seen.

Yellow-bellied shrike (Prionops alberti)Also known as the King Albert Shrike, it is a small bird that lives in the damp forests of the Albertine Rift Mountains in Central Africa. Adults are covered in glossy black feathers, with a magnificent crown of bright golden feathers on their heads. Their eyes are surrounded by distinctive orange tissue called wattles.

After not being seen for many years, the long-eared shrike was listed as an endangered species. Find a lost bird partnership.

michael harvey Researchers at the University of Texas at El Paso finally encountered this phenomenon again during a six-week expedition into the Itobwe Mountains from December 2023 to January 2024.

As team members wandered through the cloud forest, they encountered a flock of elusive birds.

“It was a shocking experience to come across these birds. I knew it might be possible here, but I wasn't prepared for how spectacular and unique it would be in my life.” ,” Harvey said in a statement.

A total of 18 Long-tailed Shrikes were spotted at three locations during the expedition. This suggests that there may be healthy populations of birds currently considered vulnerable by the International Union for Conservation of Nature.

The group also developed the red-bellied mushroom frog (Articular leptis hematogaster), last seen in the 1950s.

“Now is a great time to protect these tropical forests so we don't lose species like the long-eared shrike before they are known and studied,” Harvey said. Ta.

Surprising Images of Nearby Star-Forming Regions Captured by Hubble

astronomer using NASA/ESA Hubble Space Telescope We captured a vivid image of IRAS 16562-3959, a beautiful star-forming region in the constellation Scorpius.

IRAS 16562-3959The star, also known as 2MASX J16594225-4003451, is located 5,900 light-years away in the constellation Scorpius.

“At the center of the image, IRAS 16562-3959 is thought to contain a massive star with a mass approximately 30 times that of the Sun, which is still in the process of formation,” Hubble team members said in a statement. Ta.

“At the near-infrared wavelengths that Hubble detects, the central region appears dark because there is so much dust in the way.”

“Near-infrared light, however, primarily leaks out from two sides, the top left and bottom right, where powerful jets from massive protostars are removing dust.”

“The multi-wavelength images containing this amazing Hubble scene will help us better understand how the largest and brightest stars in the Milky Way are born.”

The new image of IRAS 16562-3959 was created from separate exposures taken in the near-infrared region of the spectrum. Hubble's Wide Field Camera 3 (WFC3).

Four filters were used to sample different wavelengths. Color is obtained by assigning different hues to each monochromatic image associated with an individual filter.

“A filter is a thin piece of highly specialized material that only allows light at very specific wavelengths to pass through,” the astronomer explained.

“We can slide them in front of the light-sensing part of the telescope, allowing us to control which wavelengths of light the telescope collects for each observation.”

“This is useful not only for certain scientific studies, but also for creating images like this.”

“Regardless of which filter was used, raw telescopic observations are always monochrome,” they added.

“However, specially trained artists and image professionals can choose colors that match the wavelength range covered by individual filters.”

“Alternatively, if a direct match is not possible, for example the data used in this image is all in the infrared range, to which the human eye is not sensitive, so the artist has chosen colors that are wisely representative of what they are trying to represent.” You can. It’s happening.”

“For example, shorter wavelengths might be assigned a bluer color and longer wavelengths a redder color, as is the case with the visible light range.”

“The data from multiple filters can then be combined to build multicolor images that look beautiful and have scientific meaning.”

Stunning Images of Jupiter’s Moon Io Captured by NASA’s Juno Orbiter

On February 3, 2024, NASA's Juno spacecraft made its second close approach to Io, the fifth and third largest of Jupiter's moons. Like the previous flyby on December 30, 2023, this second pass was approximately 1,500 kilometers (930 miles) away. During the twins' flyby, the spacecraft's JunoCam instrument returned stunning high-resolution images and raw data. The flyby is designed to provide new insights into how Io's volcanic engines work and whether a global magma ocean exists beneath the volcanic moon's rocky, mountainous surface. has been done.

The JunoCam instrument aboard NASA's Juno spacecraft imaged Io, the most geologically active object in the solar system, on February 3, 2024, from a distance of approximately 7,904 km (4,911 miles) . Image credit: NASA/SwRI/MSSS.

Io is the innermost of Jupiter's four Galilean moons and the fourth largest moon in the solar system.

Its diameter is about 3,630 km (2,556 miles), making it only slightly larger than our moon.

It is the only place in the solar system other than Earth that is known to have volcanoes spewing hot lava like those on Earth.

Io has over 400 active volcanoes, which are caused by tidal heating. This is the result of a gravitational tug of war between Jupiter's gravity and the small but precisely timed gravitational pulls from Europa and Ganymede.

The moon's yellow, white, orange, and red colors are produced by sulfur dioxide, frost on its surface, elemental sulfur, and various sulfur allotropes.

The volcano was first discovered on the island of Io in 1979, and since then studies using NASA's Galileo spacecraft and ground-based telescopes have shown that eruptions and lava fountains occur constantly, forming rivers and lakes of lava. Masu.

Only 13 large eruptions were observed between 1978 and 2006, in part because fewer astronomers were scanning the moon on a regular basis.

The JunoCam instrument aboard NASA's Juno spacecraft imaged Io on December 30, 2023, from a distance of approximately 5,857 km (3,639 miles). Image credit: NASA/SwRI/MSSS.

NASA's Juno spacecraft has been monitoring Io's volcanic activity from distances ranging from about 11,000 km (6,830 miles) to more than 100,000 km (62,100 miles), providing the first view of the moon's north and south poles .

On December 30, 2023, Juno came within approximately 1,500 km of Io's surface. The orbiter made her second close flyby of the Moon on February 3, 2024.

The second flyby mainly flew over Io's southern hemisphere, but previous flybys flew over Io's northern hemisphere.

Juno captured two plumes rising above Io's horizon on February 3, 2024. These plumes were emitted from two vents from one giant volcano, or from two volcanoes located close to each other. The JunoCam instrument photographed the plume from a distance of approximately 3,800 km (2,400 miles). Image credit: NASA / JPL-Caltech / SwRI / MSSS / Andrea Luck.

“We investigate the source of Io's massive volcanic activity, whether there is a magma ocean beneath its crust, and the importance of tidal forces from Jupiter that are relentlessly squeezing this beleaguered moon. doing.”

“There are active plumes, high mountain peaks with distinct shadows, and evidence of lava lakes, some of which look like islands.”

Starting in April 2024, Juno will conduct a series of occultation experiments that will use Juno's gravity science experiments to investigate the composition of Jupiter's upper atmosphere. This provides important information about the planet's shape and internal structure.
