Also referred to as IRAS 19019+3346, Leda 62725, or TC 872, UGC 11397 is situated in the constellation Lyra and is approximately 250 million light years distant.
The first documented mention of this spiral galaxy appeared in a galaxy catalogue compiled by Swiss astronomer Fritz Zwicky in 1966.
“At first glance, UGC 11397 seems like a typical spiral galaxy,” stated Hubble astronomers.
“It showcases two graceful spiral arms illuminated by stars, framed by dark, dense dust clouds.”
“What sets UGC 11397 apart from a standard spiral is the ultra-massive black hole at its core, which has a mass 174 million times that of the sun,” they noted.
“As the black hole ejects gas, dust, and even entire stars from its vicinity, this material heats up, creating a spectacular cosmic display.”
“Materials engulfed by black holes emit radiation ranging from gamma rays to radio waves, leading them to brighten and dim unexpectedly.”
“Nonetheless, in some galaxies like UGC 11397, thin dust clouds obscure much of this energetic activity from optical light observation.”
“Still, the rapidly growing black hole in UGC 11397 has been identified through its intense X-ray emissions.”
This discovery led astronomers to categorize it as a Type 2 Seyfert Galaxy, a classification for active galaxies whose central cores are obscured by dust and gas formations.
“Utilizing Hubble, we will examine hundreds of galaxies that host ultra-massive black holes similar to UGC 11397,” the researchers stated.
“Hubble’s observations aid us in measuring nearby supermassive black holes, understand their growth early in the universe’s history, and explore star formation in extreme conditions at the galaxy’s center.”

The sun’s corona appears as it would to the human eye during a solar eclipse, but through a green filter.
ESA/proba-3/aspiics
The synchronized movement of the twin satellites has produced the first artificial solar eclipse in space, revealing the burnt corona of the sun in remarkable detail.
The ProBA-3 mission, launched last December, is operated by the European Space Agency (ESA) and consists of two satellites positioned 150 meters apart.
One of the satellites, known as Occulter, features 1.4-meter wide discs made from carbon fiber and plastic, effectively blocking sunlight coming from the second satellite, Coronagraph. The alignment accuracy of the satellites is within one millimeter for capturing images.
In March, the satellites autonomously synchronized for extended periods, providing lengthy exposures of the solar eclipse. ESA scientists can stitch these exposures together to generate a comprehensive image of the solar corona, the outermost layer of the sun’s atmosphere.
“When I first viewed these images, it was unbelievable,” says Damien Galano from ESA. “But shortly after, it transformed into an incredible sense of achievement and pride for all our hard work.”
The image above captures the visible light of the corona, resembling how it would appear to the human eye but through a green filter.
This image illustrates the light emitted from electron-depleted iron in the most heated sections of the corona.
ESA/proba-3/aspiics
The Proba-3 satellite camera also captures light frequencies linked to specific elements within the solar corona, exemplified by the dark green image above.
“We can clearly see the substantial achievements made during COVID,” remarks Galano.

The image above illustrates the sun’s corona, artificially colored purple in polarized white light. This technique allows scientists to distinguish the polarized light from the hot corona from that scattered by interplanetary dust.
These images were primarily captured to verify the ProBA-3 mission’s functionality. When fully operational, they will take pictures of the artificial food every 19.6 hours.
This will enhance our comprehension of solar corona physics, and according to Galano, it will also improve understanding of solar winds and coronal mass ejections that influence space weather.

Though it might not be as well-known as the Hubble Space Telescope or the James Webb Space Telescope, NASA’s Landsat 7 has significantly enhanced our understanding of our planet. For over 25 years, it has been capturing the stunning landscapes of Earth from space, documenting remarkable details of the planet’s ever-changing environment.
Launched in 1999 with an expected mission duration of only five years, Landsat 7 has instead emerged as one of the longest-running Earth observation missions in history. While it doesn’t gaze into distant galaxies, its instruments are focused on the vibrant, living surfaces of Earth instead.
From an altitude of 700 km (about 435 miles), it has produced vital data for scientific research and conservation, showcasing stunning images of dynamic deserts, glaciers, forests, and coastlines.
“[Landsat 7 has] been essential in tracking environmental changes such as natural disasters, deforestation, and urban expansion,” said David Applegate, former director of the US Geological Survey.
“It documented significant events such as Hurricane Katrina in 2005, the Haiti earthquake in 2010, the Australian wildfires from 2019 to 2020, and rapid urban growth across the globe.”

Landsat 7 is scheduled to retire this month after covering 6.1 billion km (3.8 billion miles) in space and capturing over 3 million images. A carefully planned shutdown will involve depleting its batteries, turning off the fuel line heater, and rendering the communications system silent permanently. For another 55 years, the satellite will drift silently above Earth before eventually re-entering the atmosphere and burning up.
As we bid farewell, we reflect on its lens and celebrate the beauty and complexity of our planet, revealing both the impacts of deforestation and the intricate patterns of continents.

The NGC 685 is abundant in star-forming nebulae and appears as a dazzling pink cloud in recent images captured by the NASA/ESA Hubble Space Telescope.
This Hubble image illustrates the Spiral Galaxy NGC 685 on the bar. The color images were created from individual exposures captured in ultraviolet light using Hubble’s Wide Field Camera 3 (WFC3) and derived from visible and near-infrared sections of the spectrum. Built upon data gathered through six filters, different hues are assigned to each monochromatic image related to a specific filter. Image credits: NASA/ESA/Hubble/J. Lee/F. Belfiore.
NGC 685 is situated approximately 64 million light-years away in the southern constellation of Eridanus.
Previously known as ESO 152-24, IRAS 01458-5300, or LEDA 6581, the galaxy was discovered by British astronomer John Herschel on October 3, 1834.
Spanning around 74,000 light-years, the galaxy features a luminous central bar and a distinctively curved arm.
“NGC 685 is classified as a barred spiral galaxy, with its delicate spiral arms emerging from the edge of a stellar bar at the heart of the galaxy,” Hubble astronomers stated.
“The Milky Way, while not a perfect spiral, is nearly twice the size of NGC 685.”
Astronomers utilized Hubble for two observational programs focused on star formation in NGC 685.
“It’s no surprise that NGC 685 was selected for these studies. The galaxy’s spiral arms are marked by numerous patches of young blue stars,” they noted.
“Many of these star clusters are enveloped by a vibrant pink gas cloud known as the H II region.”
“The H II region is a gas cloud that gleams momentarily, especially during the birth of a massive, hot star.”
“The particularly striking H II region can be seen near the lower edge of the image.”
“Despite the visible star-forming regions, NGC 685 converts gas into stars each year at a rate of less than half the mass of the sun.”
“The data collected by Hubble across two observational programs enables us to catalog 50,000 H II regions and 100,000 star clusters in nearby galaxies.”
“By merging Hubble’s sensitive visibility and ultraviolet observations with data from the NASA/ESA/CSA James Webb Space Telescope and wireless data from the Atacama Large Millimeter/submillimeter Array, we explore the depths of dusty star nurseries and illuminate the stars within.”
Astronomers utilizing the NASA/ESA Hubble Space Telescope captured a stunning new image of the Face-On Barred Spiral Galaxy NGC 3507.
This Hubble image illustrates the NGC 3507, a barred spiral galaxy located 46 million light years away in the constellation Leo. Image credits: NASA/ESA/Hubble/D. Thilker.
NGC 3507 is situated approximately 46 million light years from Earth in the Leo constellation.
Also referred to as Hipass J1103+18, Leda 33390, or UGC 6123, this galaxy spans nearly 50,000 light years.
It was discovered on March 14, 1784, by the German-British astronomer William Herschel and is paired with the large spiral galaxy NGC 3501.
A Hubble astronomer explained, “NGC 3507 is classified as a barred spiral because its prominent spiral arms emerge from the edge of the galaxy’s central bar instead of its center.”
“In this image, we focus on NGC 3507, which is alongside its galactic companion NGC 3501, though NGC 3501 lies outside the frame.”
“While the NGC 3507 follows the typical spiral galaxy structure, its companion has a more dynamic appearance as it travels through space.”
“Though both are classified as spiral galaxies, they present themselves differently depending on the observed angle.”
“Features like spiral arms, dusty gas clouds, and vibrant star clusters are vividly displayed for galaxies as distant as NGC 3507 and NGC 3501,” the researchers noted.
“Distant galaxies tend to lack fine details.”
“See if you can identify other distant galaxies in this image; they often appear orange or yellow, showcasing hints of spiral arms with variations from round stars to elongated shapes.”
Along with its distant neighbors, NGC 3507 also features much closer objects, identifiable by four light spikes, which represent a star in the Milky Way, located merely 436 light years from Earth.
Suspended Blessing: Sleeping Sperm Whale and Her Calf
Paul Nicklen
A full belly—if you look closely, you can see the tentacles of the deep-sea squid she recently devoured hanging from her mouth.
This photo, titled The Interrupted Bounty, is one of many captured by photographer Paul Nicklen and showcased at the Photo Fair. It exudes a sense of peace, yet Nicklen experienced a whirlwind of emotions while filming it in Dominica in 2019.
“Even while my lungs ached and my mind screamed to surface just 5 meters away, I had to calm myself,” he reflects. “In that moment, my focus shifted to breathing, framing, and floating. The fear was present, but I remained centered.”
As he grounded himself, a feeling of “quiet adoration” washed over him. “It brought a certain joy, aligned with their rhythm for a while,” Nicklen recalls. “Over time, that joy has shifted into a heavier contemplation. I’m reflecting on the risks that whales now face—ocean pollution, ship strikes, entrapment in nets, and rising sea temperatures. Looking back at these images reveals lines that may not endure unless changes occur. Still, I feel fortunate. I’m honored to share their stories.”
Photo London will take place at Somerset House from May 15th to 18th. Nicklen’s work is presented by Hilton Contemporary, which also features a photograph by marine biologist Christina Mittermeyer, showcasing her striking image from Madagascar in 2008: Mandare’s Washing. It depicts brightly colored clothing drying on cracked earth, with two emaciated cows nearby on a dry stretch of the Mandare River.

Seventeen years later, Mittermeier reflects on the tumultuous feelings she experienced while taking those shots. “It wasn’t just the illness, but also the tropical fever, combined with a sense of guilt. Not guilt for being there, but for leaving,” she recounts. “The village families had no escape from the drought; they lacked alternatives, no backup resources, no taps to turn on.
Today, that guilt has evolved into a profound respect for the resilience of the locals.
“I think of the elasticity of that fabric, the dust, and how survival here is stitched together with each piece of clothing, meal, and glass of water,” Mittermeier shares. “It’s a testament to drought, but also to the overarching decisions that determine who suffers and who survives.”
Below is another stunning photograph by Nicklen titled Ephemeral Palace. Captured in 2012 on the Antarctic Peninsula, it depicts a vast iceberg adrift, destined to melt as it approaches the sea.

The final shot from Nicklen, titled Meet Face to Face, features an unexpected visitor, photographed in Svalbard, Norway in 2008. He labels the encounter with “the bear in question” as a significant highlight of his career, noting he has rarely encountered the approximately 2,000 polar bears he has documented, yet he has never succumbed to panic.

vIDEO games have been portraying soccer since the 1970s, yet they seldom dive into the realm of fandom simulation. While players can engage in the whole international tournament through the FIFA series, the games rarely depict how competition seeps into the daily lives of supporters, how entire communities become engulfed in World Cup mania, and how it transforms into a national obsession. The quintessential experience of a major match for most is encapsulated in those glorious moments of shared excitement, along with the sounds and sights of real life, whether on television or massive pub screens in the company of friends and family.
This is where Despelote steps in, a beautifully crafted game that transports players back to childhood and memory, all set against the backdrop of Ecuador’s historic 2002 World Cup qualifying campaign. Julian, an 8-year-old football enthusiast—essentially a semi-autobiographical character based on the game’s co-designer Julian Cordello—witnesses his team’s thrilling win over Peru. However, four more matches stand between Ecuador and the World Cup finals in Japan and Korea. The game unfolds as a series of intimate, immersive scenes, allowing Julian to navigate through life, balancing his responsibilities and daydreams during various life moments such as shopping trips, car rides, and school lessons.

A critical scene unfolds in a town square or during a family gathering, where Julian finds himself in a space of freedom and agency. He listens intently to adult conversations, observes an elderly man feeding pigeons, greets the shopkeeper, and enjoys moments of play with friends. The world is rendered in a single-color photograph that evokes nostalgia and simplicity.
As the gameplay evolves, Julian’s childhood experiences transition into reflections on teenage gatherings and newfound responsibilities. The socio-political context of the World Cup campaign is woven into the narrative; Ecuador was grappling with a financial crisis, causing rampant inflation and the collapse of businesses. Discussions about the tournament permeate everyday life, impacting everything from street conversations to weddings.
Additionally, other facets of Ecuadorian culture and life are beautifully integrated into the experience. Explore music, cuisine, and the resurgence of the local film industry through *Leyteros*, directed by Sebastián Cordero, creator of the 1999 crime films *Latus*, *Latones*, and *Julianne Cordero*. In this way, real life interweaves seamlessly with the gaming world, reminiscent of a poetic and self-referential Agnès Varda film. One endearing sequence even features Julian captivated by a hooky simulation on the family console.
Despelote evokes some of the remarkable works in independent narrative game design, such as *Unfinished Swan*, *Gravityborn*, and *Virginia*, yielding a thrilling experience. Though centered around one young boy in a uniquely crafted Ecuador, it captures the almost universal influence of football as a unifying social narrative. The Dutch 1974 team, Maradona’s genius in 1986, Gascoigne’s legendary goal against Scotland in Euro 96—all these moments contribute to a collective spirit. As the final qualifying match approaches, a palpable excitement and tension emerge, prompting reflections on the creative process itself, beyond the confines of traditional gameplay. This experience is both engaging and formally innovative, packing significant depth into two hours of gameplay, posing more profound questions about memory, simulation, and identity than many expansive 100-hour epics.
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.”
Superb Starling (Lamprotornis superbus) Recent studies reveal their behavior of “reciprocity,” where they assist each other with the expectation of future favors.

The Superb Starling is a passerine bird belonging to the Sturnidae family.
This species is widespread, inhabiting various regions in East Africa, including Ethiopia, Somalia, Uganda, Kenya, South Sudan, Tanzania, and beyond.
These birds form large mixed groups consisting of 7 to 60 individuals, with an average size ranging from 13 to 41 members.
“The social structure of Starlings is complex, comprising not only family units but also a mix of both related and unrelated individuals, much like humans.”
“It’s well-known that animals tend to assist their relatives to enhance genetic fitness and propagate their genes.”
“While Starlings prioritize helping relatives, they also lend support to unrelated individuals.”
Professor Rubenstein and his team discovered that this support arises through the establishment of mutual relationships.
However, proving that such behaviors are present in non-relatives remains challenging.
The study is rooted in two decades of research by the authors on these birds in Africa, thriving in the harsh savannah climate.
From 2002 to 2021, thousands of interactions among hundreds of birds were documented, alongside DNA samples to analyse genetic links.
By merging behavioral data with genetic information during 40 breeding seasons, they posed pivotal questions: Did birds prioritize aiding relatives? Did they assist non-relatives when related individuals were available? Did they reciprocate support over time?
Ultimately, the findings revealed that while helpers prioritized their relatives, they often supported specific unrelated individuals consistently, even when relatives could assist.
“Many of these birds forge friendships that develop over time,” Professor Rubenstein stated.
“Our next goal is to investigate how these relationships are formed, their longevity, and why some bonds remain strong while others diminish.”
The study was published today in the journal Nature.

True friends, as most would agree, support one another. This can mean offering emotional encouragement or lending a hand during a move. For a vibrant Sterling—a lively songbird from the African savanna—this includes feeding insects to your friends’ offspring, with the expectation that they will do the same for you in return.
Research has shown that social animals tend to form bonds primarily with their relatives. However, according to a study published in the Journal Nature Wednesday, researchers analyzed two decades of field data, revealing new interactions among unrelated members of great starling communities.
“These findings are the core of our study,” stated Dustin Reubenstein, an ecology professor at Columbia University and the paper’s author.
Alexis Earle, a biologist from Cornell University and co-author, noted that great starlings exhibit unique cooperative breeding behavior, blending family units with newcomers. New parents often depend on as many as 16 helpers.
Dr. Reubenstein’s lab has maintained a 20-year field survey of the species, encompassing 40 breeding seasons. They recorded thousands of interactions among hundreds of vocal birds and collected DNA samples to explore genetic linkages. When Dr. Earle, then a graduate student, began analyzing the data, she and her colleagues were not surprised to find that the birds predominantly assisted their relatives.
However, they were taken aback to discover that starlings also assisted non-relatives, even opting to help others when they could have aided their family members. Newcomers in the flock offered assistance to birds born within it, and vice versa. As great starlings frequently shift between parenting and supportive roles, the research team found that individuals who aided non-relatives tended to reciprocate those good deeds over time.
“Starlings consistently invest in the same valued social partners over their lives,” Dr. Earle remarked. “To me, that resembles friendship.”
Gerald Carter, an animal behavior expert at Princeton University and co-author, noted the controversy surrounding the idea of animals forming friendships with non-related individuals. Yet, increasing research supports the presence of long-term interactions among primates, elephants, crows, and whales. There are even vampire bats that share their blood meals with unrelated members of their colonies, alongside unrelated male lance-tailed manakins who act as each other’s “wingmen” to attract female attention.
Detecting long-term relationships, however, can be challenging, as Dr. Reubenstein points out. The research team required 27 seasons of data to reveal signs of reciprocity among starlings, and he believes they may still be underestimating it.
Dr. Reubenstein suggested that mutual support relationships may be more crucial than lab data indicates. “Having substantial long-term data is essential to uncovering these dynamics.”
The study presents a strong case, according to Jorg Massen, a behavioral ecologist at Utrecht University in the Netherlands who was not involved in the research. A key next step is to determine how these long-term relationships are sustained on a daily basis.
“Is it merely based on reproductive support, or does it involve other behavioral factors?” he posed.
Moreover, the behavior of great starlings suggests that everyone benefits from maintaining relationships with unrelated peers. “Birds residing in larger groups tend to have longer lifespans and produce more offspring over their lifetimes,” stated Dr. Reubenstein. In the harsh and unpredictable environments of the African savanna, maximizing resources is vital, and incorporating migrant birds enhances group stability.
According to Dr. Reubenstein, this mirrors the evolutionary trajectory of humans.
Amid growing concerns over the epidemic of human loneliness, experts may find valuable lessons in the lives of starlings. In essence, strong relationships often emerge from a foundation of support.
But you don’t need to feed your friends’ kids bugs! Luckily, there are always babysitting services available.
The two central stars of the NGC 1514 are displayed as one of the images from the NASA/ESA/CSA James Webb Space Telescope, forming this scene for thousands of years and maintaining it for thousands more.
This web image shows the planetary nebula NGC 1514. Image credits: NASA/ESA/CSA/STSCI/Michael Ressler, JPL/Dave Jones, IAC.
NGC 1514 It is about 1,500 light years away from the Taurus sign.
The object, also known as the Crystal Ball Nebula, was discovered on November 13th, 1790 by German and British astronomer William Herschel.
He pointed out that NGC 1514 was the first deep sky object that really looked cloudy. He couldn’t resolve what he saw on individual stars in the cluster, like other objects he catalogued.
The ring around NGC 1514 was discovered in 2010, but Webb is now allowing astronomers to comprehensively examine the nature of the turbulent flow of this nebula.
“This scene has been formed for at least four,000 years and will continue to change over a thousand years,” Webb Astronomers said in a statement.
“In the center there are two stars that appear as one in Webb observations, caused by vivid diffraction spikes.”
“The star follows a solid, elongated nine-year orbit, covered in an arc of dust, represented by orange.”
“One of these stars, once a massive scale several times larger than our sun, played the lead role in producing this scene.”
“When the outer layers of the star were exhausted, only the hot, compact core was left behind.”
“As a white dwarf star, its winds rose sharply and weakened, and could have blown away the material into a thin shell.”
New Webb observations show that the nebula is at a 60-degree angle, which makes it appear that the can is poured in, but it is much more likely that the NGC 1514 took the shape of an hourglass and dropped the edges.
“Look for pinchwaist hints near the top left and bottom right. The dust is orange and drifts in a shallow V-shaped shape,” the astronomer said.
“When the star reached its peak of losing material, our peers may have become very close and have had these unusual shapes.”
“Instead of creating a sphere, this interaction may have instead formed a ring.”
“The NGC 1514’s outline is most clear, but the hourglass also has some sides of the 3D shape.”
“Look for a dim, translucent orange cloud between the rings that give to the nebula body.”
Nebula’s two rings are illuminated unevenly by Webb’s observations, appearing to be more diffused at the bottom left and top right.
Researchers believe that the rings are primarily made up of very small dust grains. This will get hot enough for Webb to detect when hit by ultraviolet rays from a white star star.
“In addition to dust, Webb revealed oxygen in its chunky pink center, especially at the edges of the bubbles and holes,” they said.

An influential book by botanist and pioneering photographer Anna Atkins, almost two centuries ago. British algae photos: impressions of cyanotypes surprised readers with its scientific power and artistry. In it, Atkins presented images of seaweed collected from the British coastline using the cyanotype method, a printing process carried out by laying objects on chemically coated paper, exposing them to ultraviolet rays and creating a cyan blue background.
Artist Mandy Barker’s new book, British algae photo: Cyanotype defects she uses the same technique to draw attention to the ongoing pollution crisis facing our oceans. Like Atkins, Barker also scrutinised the British coastline. But rather than finding the beauty of nature, she saw abandoned clothes washed down on the beach. Her first discovery, she says, looked like seaweed. “It was kind of an attractive and beautiful fabric.” However, when jackets, dresses, shoes, underwear and school uniforms began to appear, the scale of the problem quickly became clear to her.
Inspired by the “seaweed-like shape” of the clothing, Barker decided to create a new cyanotype print (photo not the photo above) from this discovered fabric (photo above, not the photo above) to replicate Atkins’ work, which involves small but large changes. She draws attention to the climate costs associated with fast fashion by inventing the Latin name for clothing.

I I’ve played various Assassin’s Creed games over time, but I never truly adored them. Ubisoft’s historical fiction is almost exceptional. Many players argue that the series reached its peak in the late 2000s, particularly with the Italian Renaissance trilogy starting with Assassin’s Creed 2, featuring the charismatic hero Ezio Auditore. Since then, the franchise has become bloated, offering endless hours of repetitive open-world exploration and assassination across ancient Greece, Egypt, and even Viking Britain. The last game I delved into seriously was Odyssey, set in Ancient Greece. The settings were stunning, the gameplay somewhat engaging, and the sheer scale was utterly overwhelming.
Assassin’s Creed games serve as an incredible dive into historical fiction, effectively recreating lost periods of history for players to roam through, almost like a form of time travel. Personally, I enjoy them for the virtual tourism they offer, yet I’ve often found that a significant portion of the gameplay, roughly 80%, consists of loosely tying together moments of exploration with stealthy assassination missions.
Recently, the latest installment in the series, Assassin’s Creed Shadows, was released after multiple delays. Surprisingly, I found it to be more engaging and entertaining than many of its predecessors in years. This time, the game is set in 16th century Japan amidst the samurai and ninja conflict involving Warlord Oda Nobunaga, presenting a visually captivating and historically intriguing narrative. The two main characters in Shadows find themselves at the heart of this transformative period in Japan’s history, with each offering unique playstyles and stories that add depth to the overall experience.
The setting in Shadows is truly remarkable. Playing on the PS5 Pro, I can confidently say that this is the most visually stunning game I’ve ever encountered. The attention to detail in depicting the Japanese landscape, architecture, and natural beauty of the mountains is exceptional. The changing seasons add a dynamic element to the world, constantly offering new perspectives on the surroundings. It’s evident that a tremendous amount of effort went into creating this immersive environment, with every minute detail meticulously crafted.

One notable aspect is the inclusion of multilingual scripts, allowing players to experience the game with English voiceovers or Japanese and Portuguese subtitles, adding to the authenticity of the historical setting. Despite my limited knowledge of Japanese history and language, playing in this mode proved to be surprisingly immersive and engaging, with each conversation feeling like a delicate interplay of words and intentions. The level of nuance in character interactions was impressive, offering players the chance to influence the outcomes through their choices.
The approach in Shadows to historical accuracy is more grounded and serious compared to previous entries in the series. The characters and events draw from actual historical references, steering clear of exaggerated side quests or comedic elements in dialogues. The game strikes a balance between authenticity and entertainment, capturing the essence of the samurai and shinobi in a way that feels believable and engaging.

Two years ago, a type IA supernova event called SN 2022ABVVT was discovered in Spiral Galaxy LEDA 132905.
This Hubble image LEDA 132905, a spiral galaxy over 400 million light years in sculptor constellation. Image credit: NASA / ESA / Hubble / RJ Foley, UC Santa cruz.
LEDA 132905 in the sculptor’s constellation is over 400 million light years away.
“The galaxy’s spiral structure, resembling a bright blue star patch, appears faint,” said members of the Hubble team.
“The bright white dot between the bright center of the galaxy and the faint left end is the SN 2022ABVVT supernova.”
The supernova SN 2022ABVT was discovered in 2022 by astronomers of the asteroid landlady impacted alert system (ATLAS).
About two months later, the NASA/ESA Hubble Space Telescope observed the star explosion.
“Atlas, designed to track faint-moving signals from asteroids near Earth, also detects objects that suddenly become brighter or fade, like supernovae in the centers of galaxies, various stars, and hungry black holes,” astronomers explained.
This Hubble image of LEDA 132905 was captured using the Hubble wide field camera 3 (WFC3) in the infrared part of the spectrum.
Astronomers are interested in studying type IA supernovae, which occur when the exposed core of ancient stars ignites in a sudden and destructive nuclear fusion burst.
These supernovae are valuable for measuring accurate distances to other galaxies.
“The universe is vast, and supernova explosions are faint,” researchers stated.
“How can we be in the right place at the right time to observe a supernova?”
“Today, most supernovae are discovered by robot telescopes constantly scanning the night sky.”
“However, some are still found the traditional way, with diligent observers taking repeated images of the sky and searching for any changes.”
A century ago, American astronomer Edwin Hubble was the first to prove that this so-called “spiral nebula” lies about 2.5 million light-years away from the Milky Way. To date, the NASA/ESA Hubble Space Telescope has achieved the most comprehensive survey of the Andromeda Galaxy. It took more than 10 years to collect the data. This colorful portrait which captures the glow of 200 million stars and was created from over 600 snapshots.
This is the largest photomosaic ever assembled from Hubble observations. A panoramic view of the neighboring Andromeda galaxy, 2.5 million light years away. Image credit: NASA/ESA/B. Williams, University of Washington.
The Andromeda Galaxy (Mesier 31) is located 2.5 million light-years away and is the closest large galaxy neighbor to the Milky Way.
Hubble's sharp imaging power can resolve more than 200 million stars in the galaxy and detect only those stars brighter than the Sun. They look like grains of sand on a beach. But that's just the tip of the iceberg.
Andromeda's total population is estimated to be 1 trillion stars, with many less massive stars falling below Hubble's sensitivity limit.
“Imaging the Andromeda Galaxy was a difficult task because it is a much larger target than the galaxies that Hubble regularly observes, often billions of light years away,” Washington said. said university astronomer Zhuo Chen and colleagues.
“The complete mosaic was performed under two Hubble observing programs. In total, it required more than 1,000 Hubble orbits spanning more than 10 years.”
The Andromeda Galaxy is tilted 77 degrees to Earth's perspective and is seen almost head-on. Areas of interest include (a) a photobombing of bright blue clusters of stars embedded within the galaxy, background galaxies visible in the distance, and some bright foreground stars that are actually within the Milky Way; Masu. (b) NGC 206 is Andromeda's most prominent nebula. (c) A young population of newborn blue stars. (d) Satellite galaxy M32. This could be the remnant nucleus of a galaxy that once collided with Andromeda. (e) A dark dust band across countless stars. Image credit: NASA/ESA/B. Williams, University of Washington.
“This region is structurally unique and more sensitive to the history of galactic mergers than the northern disk mapped by the PHAT survey.”
“The combined program collectively covers Andromeda's entire disc, which is tilted 77 degrees to Earth's field of view and viewed almost head-on.”
“The galaxy is so large that the mosaic is assembled from about 600 separate fields of view.”

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.”
“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.
Astronomers using the NASA/ESA Hubble Space Telescope have taken striking new photos of barred spiral galaxy NGC 2566.
The barred spiral galaxy NGC 2566 has a prominent star bar at its center, with spiral arms emerging from each end of the bar. Image credit: NASA / ESA / Hubble / D. Tilker.
NGC2566 It is located in the constellation Leo, about 76 million light years away from Earth.
The galaxy was discovered by German-British astronomer William Herschel on March 6, 1785.
Also known as ESO 495-3, LEDA 23303, or UGCA 138, this galaxy is a member of the PGC 80593 group of at least 16 large galaxies.
“NGC 2566 appears tilted from our perspective, so its disk is almond-shaped, giving the galaxy the appearance of a cosmic eye,” Hubble astronomers said in a statement.
“As NGC 2566 stares back at us, we’ll be looking directly behind it, using Hubble to study the galaxy’s star clusters and star-forming regions.”
“Hubble data is especially valuable for studying stars that are only a few million years old.”
“These stars are bright in the ultraviolet and visible wavelengths to which Hubble is sensitive.”
Using these data, astronomers will measure the ages of NGC 2566’s stars, helping them piece together the timeline of star formation in the galaxy and gas exchange between the star-forming clouds and the stars themselves.
“Several other observatories have investigated NGC 2566, including NASA/ESA/CSA’s James Webb Space Telescope,” the researchers said.
“Webb’s data complement this Hubble image, adding a view of NGC 2566’s warm, glowing dust to Hubble’s stellar portrait.”
“NGC 2566, at the long wavelength end of the electromagnetic spectrum, has also been observed by the Atacama Large Millimeter/Submillimeter Array (ALMA).”
“ALMA is a network of 66 radio telescopes working together to capture detailed images of the gas clouds where stars form.”
The sun’s upper atmosphere, or corona, seen in ultraviolet light
ESA & NASA/Solar Probe/EUI Team
These fiery images are the clearest views of the Sun ever seen by the Solar Orbiter spacecraft.
solar orbitera joint mission between the European Space Agency (ESA) and NASA, is a state-of-the-art instrument that orbits the sun and has been sending information back to Earth since it arrived in 2020.
These images were taken in March 2023, when Solar Orbiter was less than 74 million kilometers from the sun. The photo above was taken using ultraviolet light and reveals the sun’s outer atmosphere, or corona, in great detail, showing billowing million-degree plasma exploding along the sun’s magnetic field lines. There is. Normally, bright light from the sun’s surface hides the corona. Therefore, the corona can only be seen when observing it by blocking visible light or using ultraviolet light, which typically occurs during solar eclipses.
To create this complete image of the sun’s corona, many smaller zoomed-in images had to be stitched together, resulting in this complete mosaic of 8000 pixels. In the future, Solar Orbiter will be able to obtain two such high-resolution photos of the Sun each year, according to ESA.

This second image shows what the sun’s surface, or photosphere, looks like when viewed from Solar Orbiter in visible light, the same light that our eyes can see . The temperature of this layer of the sun is approximately 4500-6000°C. The dark areas here are sunspots, which are cooler and emit less light than the surrounding areas.

Observations using the spacecraft’s magnetic instruments show that the Sun’s magnetic field is concentrated around the sunspot region (see image above). The field directs charged particles away from these areas, cooling them and giving them a dark appearance.

Solar Orbiter can also track the speed and direction of plasma as it moves across the Sun’s surface. In this velocity map (above), called a tachogram, blue represents movement toward the spacecraft and red represents movement away from the spacecraft. It shows that it diverges in its surroundings.
This collection of images helps scientists understand the behavior of the sun’s corona and photosphere. Solar Orbiter will also image never-before-seen images of the Sun’s poles at the top and bottom of the star. Currently, not much is known about the solar poles, and researchers expect these regions to look significantly different from the rest of the sun.
When it comes to meteor showers, the Leonids are known as one of the best. Famous for its fast and bright fireball meteors, the Leonid meteor shower aims to put on an impressive show.
And in unusual circumstances, the shower can turn into a full-fledged storm, and thousands of meteors can pass in front of you in an hour. Although it is not expected to reach storm-level conditions this year, it is still a sight to behold. Additionally, the Leonid meteor shower can be seen with the naked eye, so anyone can observe it without the need for binoculars or a telescope.
So when should you look up to the sky? And what should you expect from this year’s Leonid meteor shower? We’ve got all the important information below.
When is the Leonid meteor shower?
The 2024 Leonid meteor shower will reach its peak on the night of November 17-18. During this period, 10 to 15 meteors are expected to cross the night sky per hour.
Shooting star activity is expected to peak during this period, but meteors from the Leonid meteor shower are expected to be visible until November 30th.
For the best viewing, you need to find a spot with dark skies and good visibility. It also helps avoid light pollution in big cities and towns. Light from the last supermoon of the year, November’s Beaver Moon, which peaks on Nov. 15, could obstruct visibility.
Where should you look to see the Leonid meteor shower?
Pinpointing the source of the shower will give you better visibility. The Leonid meteor shower’s name comes from its constellation, Leo, where it is believed to have originated. More specifically, the Leonid meteor shower originates from a star pattern called the Sickle within the constellation Leonid.
To find the sickle, first find Ursa Major’s plow. This is a distinctive signpost to many astronomical spots (we have a complete guide on how to find it).
Look to the edge of the pot in “The Plow” to find two bright stars: Dubhe and Merek. If you draw an imaginary line between the two, going in the opposite direction, it will point in the direction of Polaris, Polaris, and the Sickle of Leo.
You don’t need to worry too much about tracking this exact location. Meteors cover most of the sky, so your best bet is to see as much of the sky as possible.
The best way to see as much of the sky as possible is to lie on your back and look up, but it’s November and nighttime temperatures in places like the UK can be below freezing, so it’s best to dress warmly or bring warm clothing. Please wear it. Find a comfortable place to cover yourself with a blanket or sleeping bag. Be patient and stay a while to let your eyes adjust to the darkness and have the best chance of catching the Leonid meteor shower.
Where did the Leonid meteor shower come from?
Meteor showers occur when the Earth, in its orbit around the sun, passes through regions of space filled with debris left behind by comets and asteroids.
In this case, the culprit is Comet Tempel-Tuttle. It is a relatively small comet that was discovered twice in separate events. It was first created by Ernst Tempel in 1865 and then by Horace Tuttle in 1866.
How many Leonid meteors can we see?
The exact number of meteors is difficult to determine. The number changes each year, but the average number of meteors is about 15 per hour. In some years, this value can be even higher, especially if there is a meteor storm.
Approximately every 33 years, a shower turns into a storm. This classification is reached when more than 1,000 meteors occur per hour. Back in 1966, viewers experienced the unique Leonids meteor shower, where thousands of meteors appeared in just 15 minutes.
The last Leonid storm occurred in 2002, so a storm in 2024 is unlikely.
These fireballs have long trails that are blue and greenish. Meteors can be missed, but they leave a long vapor train in the sky that looks like a smoke ring for several minutes.
The Leonid meteor shower is also fast, traveling at 44 miles per second (71 kilometers per second). These are considered some of the fastest meteors we can see.
The NASA/ESA Hubble Space Telescope took this photo of barred spiral galaxy NGC 1672, visible from the southern hemisphere.
This Hubble image shows NGC 1672, a barred spiral galaxy about 49 million light-years away in the constellation Sera. Color images were created from separate exposures taken in the ultraviolet, visible, and near-infrared regions of the spectrum using Hubble’s Advanced Survey Camera (ACS) and Wide Field Camera 3 (WFC3). Six filters were used to sample different wavelengths. Color is obtained by assigning different hues to each monochromatic image associated with an individual filter.

NGC1672 is located approximately 49 million light-years away in the constellation Sera.
This galaxy, also known as ESO 118-43, IRAS 04449-5920, LEDA 15941, or VV 826, has a diameter of 75,000 light years.
it was discovered It was proposed by Scottish astronomer James Dunlop on November 5, 1826.
NGC 1672 is a typical barred spiral galaxy, which differs from normal spiral galaxies in that its spiral arms do not twist all the way to the center.
Instead, they are attached to each end of the star’s straight rod that surrounds the core.
NGC 1672 is visible almost head-on and shows regions of intense star formation.
The highest concentrations of star-forming regions are near the edges of galaxies’ strong galactic bars.
NGC 1672 is Seyfert Galaxyis named after astronomer Carl Keenan Seifert, who extensively studied galaxies containing active nuclei in the 1940s. The energy output of these nuclei can exceed that of the host galaxy.
Active galaxies also include the exotically named quasars and blazars.
Each type has unique characteristics, and they are all thought to be powered by the same engine – a supermassive black hole – but seen from different angles.
“NGC 1672 is a versatile light show that showcases the impressive lights of a variety of celestial objects,” Hubble astronomers said in a statement.
“Like other spiral galaxies, its disk is filled with billions of bright stars, giving it a beautiful glow.”
“Along its two large arms, bubbles of hydrogen gas glow with a striking red light due to the powerful radiation of newly formed stars within.”
“There are some particularly spectacular stars near the center: newly formed, extremely hot stars that are embedded in a ring of hot gas and emit powerful X-rays,” the researchers said. added.
“And at its center lies an even brighter X-ray source, an active galactic nucleus produced by the heated accretion disk around NGC 1672’s supermassive black hole. This makes NGC 1672 a Seyfert galaxy. Masu.”
“But the highlight of the new photos is the most fleeting and ephemeral of these lights: supernovae. SN2017 GaxIt appears in only one of the six Hubble images that make up this composite image. ”
“this is Type I supernova Caused by the collapse of a core and the subsequent explosion of a giant star, it goes from invisible to new light in the sky in just a few days. ”
“In images taken later that year, the supernova was already fading, so it’s only visible here as a small green dot just below the bend of the spiral arm on the right.”
“In fact, this was intentional. We wanted to look for companion stars that the supernova progenitor might have had, something that would be impossible to find outside of a living supernova.”
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.”
Astronomers have used the NASA/ESA Hubble Space Telescope to capture striking new photos of LEDA 12535, a barred spiral galaxy located in the famous Perseus Cluster of galaxies.
This Hubble Space Telescope image shows LEDA 12535, a barred spiral galaxy about 320 million light-years away in the constellation Perseus. The color composite was created from images taken with the Hubble Space Telescope's Wide Field Camera 3 (WFC3) in ultraviolet, visible, and near-infrared light. It is based on data obtained through three filters. The colors are obtained by assigning a different hue to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / I. Chilingarian.
LEDA12535 It is located about 320 million light years away in the constellation Perseus.
Also known as MCG+07-07-072 or SDSS J032041.39+424814.8, it is classified as a barred spiral galaxy.
“LEDA 12535 has a highly unusual shape for a spiral galaxy, with thin arms extending from the ends of its barred nucleus and tracing a nearly circular path around the disk,” the Hubble astronomers said.
“Using a common extension of Hubble's basis system, it is classified as an SBc(r) galaxy. The c indicates that the two spiral arms are loosely wound, each completing only a half revolution around the galaxy, and the (r) refers to the ring-like structure they produce.”
“Galactic rings come in a variety of shapes, from merely unusual to rare and astrophysically important.”
“Lenticular galaxies are a type of galaxy that lies intermediate between elliptical and spiral galaxies,” the astronomers added.
“Unlike elliptical galaxies, they feature large disks but lack spiral arms.”
“Lenticular means lens-shaped, and these galaxies often feature a ring-like shape in their disks.”
“The classification of ring galaxies, on the other hand, is only applied to unusual galaxies with a round ring of gas and star formation that closely resembles spiral arms but is either completely detached from the galactic core or lacks a visible core at all.”
“They are thought to have formed from the collision of galaxies.”
“Finally, there is the famous gravitational lensing, where the ring is actually a distorted image of a distant background galaxy, formed by the 'lensing' galaxy bending the light around it.”
“The ring-shaped images, called Einstein rings, can only form if the lensed galaxy and the photographed galaxy are perfectly aligned.”
The Perseid meteor shower, one of the most stunning meteor showers in 2024, is currently in full swing and offering a breathtaking display of fast, bright shooting stars streaking across the night sky.
As we move closer to the middle of August, the excitement is set to increase. During the peak of the shower, if conditions are favorable, you could witness up to 100 meteors per hour, some of which might even turn into fiery fireballs.
Unlike other meteor showers this year, the moonlight is not expected to overshadow this magnificent event. Although the waxing crescent moon will be visible as we near the peak, it will have set below the horizon by the time meteor activity intensifies.
For a comprehensive list of meteor showers throughout the year, check out our meteor shower calendar. If you’re interested in astrophotography but unsure where to begin, expert Pete Lawrence has put together a beginner’s guide on capturing amazing photos of the moon.
When is the Perseid meteor shower in 2024?
The Perseid meteor shower will commence on July 17, 2024, and extend until around August 24. The optimal viewing time for the meteors is from midnight until dawn.
The peak of the meteor shower is expected on August 12, with increased meteor activity around this period. Since the peak occurs during the daytime, the best times to observe the Perseids are before and after the peak, specifically on the nights of August 11/12 and August 12/13.
You’ll have the best visibility between midnight and just before sunrise (around 5:30 am in the UK, 6 am in New York, and Los Angeles).
How many meteors can you see?
The Perseids are known for being one of the most active meteor showers of the year, but it doesn’t mean there will be a constant stream of meteors to observe. Most images capturing numerous meteors are the result of long exposure shots that can capture dozens, or even hundreds, of meteors in a single frame.
Under ideal conditions and dark skies, you could potentially see up to 100 meteors per hour. However, in reality, you’re likely to witness far fewer, possibly only a few dozen per hour. Nonetheless, the Perseid meteor shower remains a spectacular event.

Where to look in the sky
The most favorable direction to observe the Perseid meteor shower is directly overhead. Aim to have as much of the sky in your field of view as possible, as the meteors will traverse the entire sky and won’t be confined to a specific location.
It can be useful to know the radiant point, as it helps differentiate the Perseids from sporadic meteors. The radiant point of a meteor shower appears to be the origin of the meteors.
In the case of the Perseid meteor shower, the radiant point is within the constellation Perseus, hence the name “Perseid meteor shower.”
If you look towards the northeast early in the morning, you’ll spot the constellation Perseus positioned directly above the bright Jupiter. Taurus is situated to the right of Jupiter, and you might even catch a glimpse of Mars nearby.
Since the sun rises in the east, facing in that direction and slightly turning left will have you looking towards the northeast. However, don’t worry if you’re unsure of the direction – meteors can appear anywhere overhead.
Perseus lies between the prominent “W” of Cassiopeia and the Pleiades star cluster. If you’re having difficulty locating the radiant point, an astronomy app can assist you (check out our recommended astronomy apps).
* The closest conjunction of Mars and Jupiter is set to occur on August 14, 2024. This will be the closest conjunction of the two planets until 2033, potentially offering an extraordinary sight alongside the Perseid meteor shower.
What causes the Perseid meteor shower?
Meteor showers manifest when a parent object (typically a comet or asteroid) leaves behind a trail of debris in its path around the Sun. As Earth intersects with this debris stream, the particles interact with the atmosphere, creating luminous streaks known as shooting stars.
Regular meteor showers like the Perseids follow a predictable pattern, occurring at the same time each year and peaking when Earth’s orbit intersects with the densest part of the shower.
According to astronomer David Schneider, “As Earth passes through the debris stream, the density of particles increases to a maximum and then decreases again. This usually takes a few weeks, but can also take a few days. The meteor shower peaks during the period of maximum density.” Presenter Pete Lawrence further elaborates.
In the case of the Perseids, Comet Swift-Tuttle serves as the parent body, which is a sizable comet composed of dust, ice, and rock. With a nucleus diameter of approximately 26 kilometers (about 16 miles) and a 133-year orbit around the Sun, Comet Swift-Tuttle is classified as a short-period comet denoted by the “P” in its official designation, 109P/Swift-Tuttle.
The comet’s last visible appearance was in 1992, with its next anticipated return in 2125 or 2126. While it was too dim to be observed with the naked eye in 1992, a clearer view is expected a century from now.
Will the moon affect visibility?
This year, moonlight may pose a challenge as a half moon will be visible on the evenings of August 11 and 12 before and after the peak. The moon’s luminosity will gradually increase as it approaches full moon status on August 19.
If observing at night, you may have to contend with moonlight obstruction, with the Moon being 51% bright on August 12 and 61% bright on August 13.
However, as the Perseid meteor shower activity intensifies after midnight on both nights, observing in the early morning should not be hindered by the moon’s light.
The optimum viewing time for the Perseid meteor shower is before sunrise between midnight and 5:30 am in the UK and 6 am in the US. With the moon below the horizon, there will be a higher probability of witnessing more meteors.
Tips for Maximizing Your Meteor Watching Experience
You don’t need a telescope or binoculars to enjoy the Perseid meteor shower; it’s best observed with the naked eye to capture a wider expanse of the sky than through optical devices.
“For optimal visibility, watch in a dark, moonless sky and allow at least 20 minutes in complete darkness to acclimatize to your surroundings,” suggests Lawrence. “A reclining chair provides an ideal vantage point for meteor observation.”
“Spend at least 30 minutes, if not longer, watching the sky. The rest is up to chance, but witnessing a bright summer meteor streaking across the sky will leave a lasting impression,” he adds.
Here are some tips to help you maximize your meteor viewing experience.
Avoid bright lights. Choose viewing locations away from bright artificial lights and ensure that streetlights are not directly in your line of vision.
Allow your eyes to adapt. Spend about 20 minutes outside until your eyes adjust to the darkness.
Use a red light filter when looking at your phone. This can be a physical red filter or an app that maintains your night vision until your eyes acclimate.
Choose the right time: Early morning is the prime time to witness the Perseid meteor shower at its peak activity and with the Moon below the horizon.
Block out the moon. If unable to observe in the early morning, still look out for meteors in the evening. During the peak on August 11/12 and 12/13, the Moon will be about 50-60% illuminated, so position yourself where the Moon is obscured by buildings or trees for better viewing.
Keep a wide field of vision. Maximize your peripheral vision to see as much of the sky as possible.
Beware of fireballs. The larger particles from the comet fragments responsible for the Perseid meteor shower can produce bright, long-lasting bursts of light, known as fireballs.
Identifying Perseid Meteors
While other meteors might be visible during this event, they are considered sporadic meteors.
Referred to as “sporadic meteor showers,” these meteors can appear from any direction in the sky and are not linked to a specific meteor shower like the Perseids (albeit they may originate from undiscovered meteor showers).
Lawrence differentiates between sporadic and shower meteors, stating: “Sporadic meteors occur when a small rock, typically the size of a grain of sand, enters Earth’s atmosphere, vaporizes, and creates a luminous streak known as a meteor trail. These occur randomly and can appear at any time, from any direction.”
Distinguishing between a sporadic meteor and a Perseid meteor shower can be tricky, but it’s based on their apparent direction in the sky. Meteor showers typically emanate from the radiant point associated with the shower, while sporadic meteors can streak across the sky from any direction at any given time.
According to Lawrence, “Meteor showers, in contrast [to sporadics], occur when a stream of sand-sized particles in orbit around the Sun intersects Earth’s atmosphere. Associated with comets and possibly asteroids, these particles are released over time and dispersed into orbit.”
“As they follow parallel orbits around the Sun and enter the atmosphere, they appear to originate from the same region of the sky, known as the shower’s radiant point.”
Knowing the radiant point of a specific meteor shower (such as the constellation Perseus for the Perseid meteor shower) enables you to discern whether the meteor you’re witnessing belongs to that meteor shower or if it’s a sporadic meteor.

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.
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.”
More than 3,500 photos were submitted for the award, and Karina Leterrier Baeza's photo was among the 30 finalists. Arctic DragonThis photo taken at Arctic Henge in Iceland shows the aurora borealis, the result of a geomagnetic storm caused by a coronal mass ejection, resembling a rearing dragon.
The final candidates are The cry of a dying star (Below), photo by Jan Sainty. The “star” in question is actually the remnant of a supernova explosion, when a star dies and explodes, releasing a tremendous amount of light and energy. This explosion occurred about 10,000 years ago.
Sainty combined clear skies and a long exposure in the Atlas Mountains of Morocco to capture rarely seen details of this glowing remnant, called Cygnus Loop, named after the famous painting. scream Sainti said the painting symbolizes Edvard Munch's “The Scream,” but also the “scream” that reverberates through the universe after a star dies.

The magnificent tree frog (Litoria splendida) is normally green, but this mutant is blue
J Barker/AWC
A rare blue frog found in the Kimberley region of Western Australia has stunned researchers who say the unusual colouring is probably due to a genetic mutation causing it to lose certain skin pigments.
As its name suggests, the magnificent tree frog (Litoria splendida) is already a spectacular animal, so when Jake Barker When he saw a bright blue specimen on a bench in a workshop at the Australian Wildlife Conservancy’s Charnley River-Artesian Range Wildlife Sanctuary in April, he was shocked.
The amphibians are normally a vibrant green, which is a common colour for tree frogs and is thought to camouflage them.
“I knew as soon as I saw it that it was rare,” says Barker. “It’s not often that you get to see a blue frog.” It has been seen a number of times since, but won’t be captured for research, he says.
“It’s far too pretty and far too unique and it would be a pity to take it away from its natural habitat,” says Barker. “We’ll leave it to live out its days and hopefully get to see it many more times in the future.”
Jodi Rowley At the Australian Museum in Sydney, the animal may be the “most beautiful, aberrant-coloured frog” that she has ever seen. “And I have seen tens of thousands of frogs.”
From the photos she has seen, Rowley says the frog is at least 2 to 3 years old. The species may live to be 20 years old, so the blue individual is likely to be around for a while unless caught by a predator.
She says the frogs’ skin colour is determined by the combination of three chemicals – melanophores, which provide blacks and browns; xanthophores, which provide yellow pigments; and iridophores, which reflect blue colours. Normally, the yellows and blues combine to make green, but it is thought the new blue frog has a mutation that means it is missing the yellow pigments and the blue dominates.
“Blue is probably a bit more obvious to predators,” says Rowley, “which is why we don’t see many blue frogs.”
debtMark Aitken has been working on a photo series in Lapland for the past two years. The Presence of Absence“The work explores the delicate, sometimes eerie, boundary between life and death experienced by people living in this extreme climate and landscape,” he says.
Aitken, who was born in New Zealand, grew up in South Africa and has lived in London for many years, took the photo on a sheep farm this spring. “Kukkola is a small village on the Finnish-Lapland border on the Tornio River close to Sweden. The farm has been running for 20 years and this lamb is one of around 100 born in March and April,” Aitken says.
The lamb doesn’t have a name, but the inquisitive collie does: “He’s a lively young male called Possu, which means piglet. I saw the two animals interacting when I went into the barn to find Jaana, one of the farm owners, and arrange a time to take her portrait.”
Aitken usually shoots on 35mm film and likes to take his time preparing to take a photograph, especially when working with people. “When the right atmosphere, light and mood is achieved, I press the shutter. I like this discipline. This process also applies to printing in the darkroom. Only then does the memory of that moment become associated with the photograph.”
That day, he didn’t have his camera with him, but he did have his iPhone SE, and before his eyes the theme of his series was playing out in a whole new way: “I was amazed and intrigued by the inter-species relationships. The possu were trying to herd the lambs, but they were failing. The lambs hadn’t yet learned fear.”
In this new image, the NASA/ESA Hubble Space Telescope captures the glow of spiral galaxy NGC 4951.
This Hubble image shows NGC 4951, a spiral galaxy about 49 million light-years away in the constellation Virgo. Image courtesy of NASA / ESA / Hubble / D. Thilker / M. Zamani, ESA and Hubble.
NGC 4951 is located about 49 million light-years from Earth in the constellation Virgo.
Also known as AGC 530015, IRAS 13025-0613, or LEDA 45246, the galaxy has a diameter of about 65,000 light-years.
It was discovered on April 17, 1784 by German-born British astronomer William Herschel.
The new image of NGC 4951 is Hubble’s Wide Field Camera 3 (WFC3) is in the ultraviolet, infrared, and optical parts of the spectrum.
It is based on data acquired through six filters: color is generated by assigning a different hue to each monochrome image associated with an individual filter.
“The data used to create this image was taken by Hubble as part of a program to study how matter and energy move in nearby galaxies,” Hubble astronomers said. statement.
“Galaxy undergoes continuous cycles of star formation: gas within galaxies forms molecular clouds, which collapse to form new stars, and then the formed clouds are dispersed by powerful radiation and stellar winds in a process called feedback.”
“The remaining gas will form new clouds elsewhere,” the researchers added.
“This cycle of matter and energy transfer determines how quickly a galaxy forms stars and how quickly it exhausts its supply of gas — in other words, how the galaxy evolves throughout its life.”
“To understand this evolution, we need to know the nebulae, stars and star clusters in our galaxy, when they formed and what their past behavior is.”
“The Hubble Telescope has always excelled at measuring stellar populations, and its work tracking gas and star formation in galaxies including NGC 4951 is no exception,” the astronomers noted.
NGC 4951 is also classified as a Seyfert galaxy, a type of galaxy that has a so-called active galactic nucleus.
“The image gives a good glimpse into how energetic the galaxy is and some of the dynamic galactic activity that transports matter and energy throughout the galaxy: a glowing core surrounded by swirling arms, pink-hued star-forming regions, and thick dust,” the researchers said.
Astronomers used images from the NASA/ESA Hubble Space Telescope and the NASA/ESA/CSA James Webb Space Telescope to create a new 3D visualization of the Pillars of Creation, three towers of gas and dust within the Eagle Nebula.
The Pillars of Creation are three towers of gas and dust located about 6,500 light-years away in the constellation Serpens.
These are fascinating but relatively small features of the Eagle Nebula (also known as Messier 16), discovered in 1745 by Swiss astronomer Jean-Philippe Roy de Chéseaux.
The Pillars of Creation are approximately 4-5 light years long, and the nebula is 55-70 light years wide.
They are caused by massive, newly formed, blue-white O and B type stars emitting intense ultraviolet radiation and stellar winds that blow away less dense material from around them.
“By flying between the pillars, viewers will experience the 3D structure of the pillars and see how they look different in Hubble's visible light view and Webb's infrared light view,” said Dr. Frank Summers, principal visualization scientist at the Space Telescope Science Institute.
“This contrast helps us understand why we need multiple space telescopes to observe different aspects of the same object.”
“The four pillars of creation are made mostly of cold molecular hydrogen and dust, eroded away by violent winds and intense ultraviolet radiation from nearby hot young stars.”
“Protruding from the top of the pillar is a finger-like structure larger than our solar system. Embedded within this finger may be a newborn star.”
“The tallest pillar stretches for three light years, which is three-quarters of the distance between the Sun and the next nearest star.”

The film takes visitors through a 3D structure of the Pillars of Creation.
“Making the Pillars of Creation in 3D was always something we had in mind,” said Dr Greg Bacon, also of the Space Telescope Science Institute.
“By combining the Webb data with the Hubble data, we were able to get a much more detailed look at the pillars.”
“Understanding the science and knowing how to best represent it enabled our small, talented team to rise to the challenge of visualizing this iconic structure.”
This new visualization allows viewers to experience how two of the world's most powerful space telescopes work together to provide a more complex and holistic portrait of the pillar.
Hubble will observe objects glowing in visible light at thousands of degrees, while Webb's infrared vision is sensitive to cooler objects at temperatures of hundreds of degrees, allowing it to penetrate the obscuring dust and see the stars embedded in the pillar.
“The combined observations from NASA's space telescopes across many wavelengths of light expand our understanding of the universe,” said Dr. Mark Crumpen, director of the Astrophysics Division at NASA Headquarters.
“The Pillars of Creation region continues to provide us with new insights that improve our understanding of how stars form.”
“This new visualization now allows everyone to experience this rich and captivating landscape in a new way.”
The NASA/ESA Hubble Space Telescope captured this stunning image of a barred spiral galaxy called NGC 4731.
This Hubble Space Telescope image shows NGC 4731, a barred spiral galaxy about 43 million light-years away in the constellation Virgo. Image courtesy of NASA / ESA / Hubble / D. Thilker.
NGC 4731 It is located in the constellation Virgo, about 43 million light years from Earth.
Also known as IRAS 12484-0607, LEDA 43507, and UGCA 302, it is classified as a barred spiral galaxy.
“Barred spiral galaxies outnumber regular spiral and elliptical galaxies combined, making up about 60 percent of all galaxies,” the Hubble astronomers said.
“The bar-like structure we see is the result of the orbits of stars and gas in our galaxy aligning, forming dense regions where individual stars move in and out over time.”
“This is the same process that maintains the spiral arms of our galaxy, but in the case of barred galaxies it's a bit more mysterious. As spiral galaxies mature they seem to form a bar at their centre, which explains the large number of bar structures we see today. But later on the bar can also be lost if the accumulated mass along it becomes unstable.”
“The orbital patterns and gravitational interactions of galaxies support the bar-like structure of the galaxy, transporting matter and energy and promoting star formation.”
“Indeed, the observing program studying NGC 4731 seeks to investigate this flow of matter within the galaxy,” they added.
beginning discovered Discovered on April 25, 1784 by German-born British astronomer William Herschel, NGC 4731 has a diameter of about 80,000 light years.
With LEDA 43526 Galaxy, Forms Holm 472, a pair of interacting galaxies.
NGC 4731 is also a member of the NGC 4697 galaxy group. Located Near the Virgo Supercluster.
“Beyond the bar, NGC 4731's spiral arms extend far beyond the scope of this close-up Hubble image,” the astronomers said.
“The galaxy's elongated arms are thought to be the result of gravitational interactions with other nearby galaxies in the Virgo Cluster.”
The color image of NGC 4731 includes ultraviolet, near-infrared, and optical observations. Hubble's Wide Field Camera 3 (WFC3).
Six filters were used to sample different wavelengths, and color was generated by assigning a different hue to each monochromatic image associated with an individual filter.
“The richness of color reveals the galaxy's swirling gas clouds, dark dust bands, bright pink star-forming regions, and most notably, its long, luminous arms stretching out behind it,” the researchers said.
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.”
Thanks to a new visualization created on a NASA supercomputer, we can now dive into the event horizon, the point of no return for a black hole.
“People often ask about this, but simulating these hard-to-imagine processes is the key to bringing the mathematics of relativity to reality,” said Dr. Jeremy Schnitman, an astrophysicist at NASA’s Goddard Space Flight Center. “It helps us connect this with real-world consequences in the universe.”
“So I simulated two different scenarios: one in which the camera, standing in for the daring astronaut, misses the event horizon and the slingshot recedes; This is a scenario in which your fate will be determined.
To create the visualization, Dr. Schnitman worked with scientist Brian Powell at Goddard Space Flight Center and used the Discover supercomputer at the NASA Climate Simulation Center.
It took about five days to generate about 10 terabytes of data and run on just 0.3% of Discover’s 129,000 processors. It would take a typical laptop more than a decade to do the same thing.
The destination is a supermassive black hole with a mass 4.3 million times that of the Sun, comparable to the monster at the center of the Milky Way.
“If I had a choice, I would want to fall into a supermassive black hole,” Dr. Schnitman said.
“Stellar-mass black holes, containing up to about 30 solar masses, have much smaller event horizons and stronger tidal forces, and can tear apart approaching objects before they reach the horizon.”
This occurs because the gravitational force at the edge of the object near the black hole is much stronger than at the opposite edge. Falling objects stretch like noodles, a process astrophysicists call spaghettification.
The simulated black hole’s event horizon spans about 16 million miles (25 million km), or about 17% of the distance from Earth to the sun.
A flat, swirling cloud of hot, glowing gas called an accretion disk surrounds it and serves as a visual reference as it falls.
The same goes for glowing structures called photon rings, which are formed near black holes by light that has circled the hole one or more times.
A starry sky background seen from Earth completes the scene.
As the camera approaches the black hole, approaching the speed of light itself, the glow from the accretion disk and background stars is amplified, similar to the pitch of the sound of an approaching race car increasing.
If you look in the direction of travel, the light will appear brighter and whiter.
The film begins with a camera located some 640 million km (400 million miles) away, and a black hole quickly fills the field of view.
In the process, the black hole’s disk, photon ring, and night sky become increasingly distorted, even forming multiple images as light traverses an increasingly distorted space-time.
In real time, the camera takes about three hours to fall to the event horizon, performing nearly two full 30-minute orbits along the way. But for those observing from afar, it will never get there.
As the space-time distortion increases as you approach the horizon, the camera’s image slows down and appears to stop in front of you. This is why astronomers originally called black holes “frozen stars.”
At the event horizon, even space-time itself flows inward at the speed of light, the speed limit of the universe.
Once inside, both the camera and the spacetime it moves through hurtle towards the center of the black hole. A one-dimensional point called a singularity, where the laws of physics as we know them no longer work.
NASA’s visualization shows a camera tracking a supermassive black hole, similar in mass to that at the center of our galaxy, as it approaches, briefly orbits, and crosses the event horizon (point of no return). Masu. Image credit: J. Schnittman & B. Powell, NASA Goddard Space Flight Center.
“Once the camera crosses the horizon, there are only 12.8 seconds left before spaghettification destruction,” Dr. Schnitman said.
From there, the singularity is only 128,000 km (79,500 miles) away. The last leg of this voyage is over in the blink of an eye.
In another scenario, the camera orbits close to the event horizon, but never crosses it and flees to safety.
If an astronaut were to fly this six-hour round trip, and her co-worker on the mother ship was far away from the black hole, she would return 36 minutes younger than her co-worker.
That’s because time slows down when you move near a strong source of gravity or at speeds close to the speed of light.
“This situation could become even more extreme,” Dr. Schnitman says.
“If a black hole were rotating rapidly, like the one shown in the 2014 movie, interstellar, she would return many years younger than the sailors. ”
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have captured the most detailed images ever of the Horsehead Nebula, one of the most distinctive objects in our sky.
At the bottom of this Web/NIRCam image, a small portion of the Horsehead Nebula is visible up close as a curved wall of thick, smoky gas and dust. Above the nebula, various distant stars and galaxies can be seen all the way to the top of the image. Image credits: NASA / CSA / ESA / Webb / K. Misselt, University of Arizona / A. Abergel, IAS, Université Paris-Saclay, CNRS.
The Horsehead Nebula is located in the constellation Orion, about 1,500 light-years from Earth.
Also known as Barnard 33, this nebula is visible only because its indistinct dust is silhouetted against the brighter nebula IC 434.
The Horsehead Nebula is just one small feature of the Orion Molecular Cloud Complex, with the glowing Flame Nebula dominating the center of this view.
The nebula was first recorded by Scottish astronomer Williamna Fleming on February 6, 1888.
The object is formed by a collapsing cloud of interstellar matter and shines in the light of a nearby hot star.
The gas cloud surrounding the horsehead has now disappeared, but the protruding columns are made of stronger material that is less erodible.
Astronomers estimate that the Horsehead Formation has about 5 million years left to collapse.
The new image from the web focuses on the upper illuminated edge of the nebula’s characteristic dust and gas structures.

“In such regions, ultraviolet light from young massive stars creates a region of warm, nearly neutral gas and dust between the fully ionized gas around the massive star and the clouds they are born into. .”
“This UV radiation has a strong effect on the gas chemistry in these regions and acts as the most important heat source.”
“These regions occur where the interstellar gas is concentrated enough to remain neutral, but not dense enough to prevent the transmission of deep ultraviolet light from massive stars.”
“Light emitted from such PDRs will be used to study the physical and chemical processes that drive the evolution of the interstellar medium in our galaxy and throughout the universe from the early days of active star formation to the present day. We provide unique tools for
“The Horsehead Nebula, due to its close proximity and near-edge-on geometry, provides an opportunity for astronomers to study the physical structure of the PDR and the evolution of the chemical properties of gas and dust within their respective environments and transition regions. is an ideal target for “among them. “
“This is considered one of the best objects to study how radiation interacts with the interstellar medium.”
“Thanks to Mr. Webb. mm (mid-infrared measuring instrument) and NIRCam “We used (near-infrared camera) equipment to reveal for the first time small-scale structures at the end of an illuminated horsehead,” they said.
“We also detected a network of stripes extending perpendicular to the PDR front and containing dust particles and ionized gas entrained in the nebula's photoevaporative flow.”
“These observations allowed us to investigate the effects of dust attenuation and ejection, and to better understand the multidimensional shape of the nebula.”
“Next, we will study the spectroscopic data obtained from the nebula to demonstrate the evolution of the physical and chemical properties of the material observed throughout the nebula.”

Since its launch in 1990, the NASA/ESA Hubble Space Telescope has made 1.6 million observations of more than 53,000 celestial objects.
To date, the Space Telescope Science Institute's Mikulski Space Telescope Archive contains 184 terabytes of processed data.
Since 1990, 44,000 scientific papers have been published from Hubble observations.
Hubble is the most scientifically productive space astrophysics mission in NASA history.
Demand for the use of Hubble is so high that it is currently oversubscribed by a factor of 6 to 1.
Most of Hubble's discoveries, such as supermassive black holes, exoplanet atmospheres, gravitational lensing by dark matter, the presence of dark energy, and the abundance of interstellar planet formation, were not anticipated before launch.
To commemorate the 34th anniversary of Hubble's launch, astronomers took a snapshot of the planetary nebula Messier 76.
“Messier 76 is located approximately 3,400 light-years away in the northern constellation of Perseus,” Hubble astronomers said.
“It is classified as a planetary nebula, an expanding shell of glowing gas ejected from a dying red giant star. The star will eventually collapse into a super-dense, hot white dwarf.”
“Although planetary nebulae are not related to planets, they got their name because astronomers in the 1700s using low-power telescopes thought these types of objects resembled planets.”
“Messier 76 consists of a ring that is visible head-on as a central bar structure and two lobes located at openings on either side of the ring. Before burning out, the star ejected a ring of gas and dust. ”
“This ring was probably formed by the influence of a star that once had a binary companion.”
“This sloughed off material formed a thick disk of dust and gas along the orbital plane of the companion star.”
“The hypothetical companion star is not seen in the Hubble image, so it may have been later swallowed by the central star.”
“The host star has collapsed to form a white dwarf,” the researchers said.
“It is one of the hottest stellar remnants known, at a scorching 139,000 degrees Celsius (250,000 degrees Fahrenheit), 24 times the surface temperature of the Sun.”
“The blazing white dwarf is visible pinpointed in the center of the nebula. The stars visible projected beneath it are not part of the nebula.”
“Sandwiched by the disk, two clumps of hot gas escape from above and below the 'belt' along the star's axis of rotation perpendicular to the disk.”
“They are propelled by hurricane-like outflows of material from dying stars, tearing apart space at 2 million miles per hour.”
“That's fast enough to travel from Earth to the Moon in just over seven minutes.”
“This intense stellar wind is channeling cooler, slower-moving gas that was ejected during the star's early stages of life, when it was a red giant.”
“Intense ultraviolet radiation from superhot stars makes the gas glow. The red color is due to nitrogen, and the blue color is due to oxygen.”
“Given that our solar system is 4.6 billion years old, according to cosmological timekeeping, the entire nebula is a fleeting event. It will disappear in about 15,000 years.”
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.
Astronomers using the NASA/ESA Hubble Space Telescope have taken photos of NGC 3783, a bright barred spiral galaxy in the constellation Centaurus.

Also known as ESO 378-14, LEDA 36101, or 2XMM J113901.7-374418, this galaxy was first discovered It was announced by British astronomer John Herschel on April 21, 1835.
NGC 3783 is home to a rapidly rotating black hole of 2.8 million solar masses.
It is a major member of the NGC 3783 galaxy group, which is a collection of 47 galaxies.
“Like galaxy clusters, galaxy groups are gravitationally bound collections of galaxies,” the Hubble astronomers said.
“However, galaxy groups are smaller and contain fewer members than galaxy clusters. Galaxy clusters can contain hundreds or even thousands of member galaxies, whereas galaxy groups typically contain fewer than 50. It does not include galaxies that exceed
“The Milky Way is actually part of a group of galaxies known as the Local Group, which includes two other large galaxies (Andromeda and the Triangular Galaxy) and dozens of satellite galaxies. Contains dwarf galaxies.
“On the other hand, the NGC 3783 galaxy group contains 47 galaxies,” they added.
“It also appears to be at a fairly early stage in its evolution, making it an interesting subject to study.”
“Although the focus of this image is spiral galaxy NGC 3783, your eye is equally focused on a very bright object in the lower right-hand portion of this image. This is the star. HD 101274” said the researchers.
“The perspective of this image makes the stars and galaxies appear to be close companions, but this is an illusion.”
“HD 101274 is only about 1,530 light-years from Earth, which means it is about 85,000 times closer than NGC 3783.”
“This explains how a single star can appear to outshine an entire galaxy.”
According to scientists, NGC 3783 type I Seyfert galaxy — A galaxy with a bright central region.
“In this image, thanks to five separate images taken at different wavelengths of light, Hubble shows incredible detail, from the glowing central bar to the thin, winding arms and the dust that passed through them. ,” the researchers said.
“In fact, the center of the galaxy is bright enough for Hubble to exhibit diffraction spikes that are normally only seen in stars such as HD 101274.”
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.”
“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.”
It has been close to two years since the world was first introduced to Sagittarius A* (Sgr A*), the supermassive black hole residing at the center of the Milky Way.
A true behemoth, Sgr A* boasts a mass equivalent to 4 million suns and is encircled by hot pockets of swirling gas. Despite its immense size, it sits about 27,000 light-years away from Earth, appearing in the sky only as large as a donut on the moon’s surface.
In a recent study published in the Astrophysics Journal Letter and released by the event horizon telescope (EHT), Sgr A* was captured in polarized light for the first time.
Similar to how sunglasses can filter polarized light from the sun, astronomers utilize polarized light to unveil concealed magnetic fields.
The lines within the image indicate the direction of polarization, which correlates with the structure of the magnetic field surrounding the black hole.
“The spiral pattern observed swirling around the black hole signifies that the magnetic field must also be swirling, indicating a very strong and ordered field,” stated Dr. Sarah Isaun, an Einstein Fellow and co-leader of the project in the NASA Hubble Fellowship Program, as quoted in BBC Science Focus.

The first-ever image of a black hole was unveiled by EHT in 2019, featuring a much grander black hole at the core of the Messier 87 galaxy (M87*).
M87* is approximately 1,000 times heavier than Sgr A*, leading to a slower rotation making it easier to image.
Further developments include astronomers releasing images of the magnetic field encompassing M87* in 2021. Overcoming the challenge of capturing our own supermassive black hole in polarized light took an additional three years.
In a surprising revelation, despite the contrasting sizes of the two black holes, the new images demonstrate strikingly similar magnetic field structures, emphasizing the prevalence of strong magnetic fields in both. This highlights a fundamental feature of supermassive black holes.
Isaun emphasized, “Sgr A* now holds a polarization structure remarkably akin to the larger, more potent M87* black hole, supporting the significance of a robust, well-ordered magnetic field in these entities.”

Previous investigations on M87* disclosed that the encircling magnetic field generates potent jets of energy and matter extending far beyond the galaxy. While astronomers have visualized the jet around M87*, it has remained elusive around Sgr A*. However, recent images unveil remarkable similarities between the two black holes, suggesting the potential existence of jets in both.
Isaun highlighted, “The jets within the host galaxy can stimulate or counteract star formation, exhibiting a fascinating interplay between the dynamics of these emanating jets from these black holes and the evolvement of the host galaxy. There exists a connection.”
“I believe we can extract valuable insights into our galaxy’s history from this connection.”
Upon the release of this image in 2022 by the EHT collaboration, it served as the premier visual evidence of a supermassive black hole residing at the heart of our galaxy, Sagittarius A*. – Image credit: EHT Collaboration
The upgraded EHT is set to observe Sgr A* once more next month, with astronomers hopeful of uncovering concealed jets and other facets of the galaxy’s central region.
Anticipate further groundbreaking revelations from EHT, potentially including more awe-inspiring images and even real-time video footage in years to come.
