This mesmerizing shot of the perfect alignment of the sun and full moon over Utah's Valley of the Gods last October is raising expectations for next month's total solar eclipse in North America.
This image, a collaboration between photographers Andrew McCarthy and Daniel Stein, shows an annular solar eclipse in which an outer “ring of fire” forms because the moon is too far from Earth to completely cover the sun. I am. The shot is the result of digitally stitching together thousands of images, combining Stein's landscape photography skills with McCarthy's experience capturing images of the sun.
After months of planning, the pair set up cameras and telescopes at carefully selected desert locations to capture the key shots, taking into account weather patterns, eclipse duration, and terrain features. did.
The image was published by Social media March 8th, exactly one month before a total solar eclipse, in which the moon completely covers the sun, will pass over North America. It will blanket much of the continent in darkness or completely, from Canada to the United States and Mexico. The path of the total eclipse will be much wider than the last similar solar eclipse in the region, covering almost 200 kilometers compared to about 115 kilometers in 2017.
“It’s easy to take the sun for granted, but [sun and moon] When combined during a solar eclipse, they are breathtakingly beautiful. I feel that incorporating landscape elements adds a sense of grounding to the images and allows the viewer to connect more deeply with the work,” says Stein.
Photographing a solar eclipse takes a little practice

Although some people spend years planning trips to see a total solar eclipse, the moment itself lasts only a few minutes at most. A well-taken photo will help you remember the moment years later.
Fortunately, with a little practice, even beginners can capture great images. Learn how to photograph a solar eclipse without any prior experience or fancy camera equipment.
location, location, location
Of course, you can’t photograph a solar eclipse unless you’re in its path. On April 8, everyone in North America will see at least a partial solar eclipse. A partial solar eclipse must be viewed through eclipse glasses and photographed using a solar filter (see details below).
Only those who have entered the path of totality can see the total solar eclipse. Much of the experience will be the same, with partial stages requiring eclipse glasses and eclipse filters, but midway through totality, where the moon completely blocks the sun for several minutes. Only during this period will the eclipse glasses and solar filters come off, allowing you to see and photograph the sun’s corona with the naked eye. This is the shot everyone wants.
How to photograph a total solar eclipse using a smartphone
If you’re in the middle of a totality, forget about handheld video or zooming in on the eclipse sun. The results of using a smartphone will be disappointingly bleak. Instead, focus on taking wide-angle shots that use silhouettes of people and objects to show off their overall beauty.
solar eclipse 2024
On April 8th, a total solar eclipse will pass over Mexico, the United States, and Canada. Our special series covers everything you need to know, from how and when to see a solar eclipse to the strangest solar eclipse experience of all time.
Just before dark, put your phone into wide-angle mode. Focus on something in the middle distance and press and hold your finger on the screen to lock focus. Burst mode allows you to capture images continuously as soon as totality begins. That way, you can catch the “diamond ring,” the last and first beads of sunlight peeking around the moon just before and after totality.
How to photograph a total solar eclipse with a camera
If you have a manual DSLR or mirrorless camera and a variety of lenses, you can choose to shoot wide-angle or close-up of the eclipse. In partial phases, solar filters should be used.
Just before totality, make sure the partially eclipsed Sun is in focus and set your camera to bracketing mode (if you want to take three different exposures of the same image). “Make sure your camera is shooting at a low ISO (200-400) before and after totality to reduce noise,” he says. Mike Mezur, nature photographer. Remember to remove the solar filter during the diamond ring, take a bracket shot during totality, and put the solar filter back on as soon as he sees the second diamond ring at the end of totality.
How to take photos of a partial solar eclipse
To capture impressive shots of a partially eclipsed sun with your smartphone, you need to use a solar filter and keep your smartphone still. The latter can be done by using a tripod and delaying the shutter for a few seconds. There is no problem if you use solar eclipse glasses for the filter. If you have a spare lens, try cutting out one lens and taping it to your phone’s camera lens. Another option is to purchase a smartphone eclipse filter from a company such as: solar snap or business solar.
Smartphones aren’t prone to damage when pointed at the sun, but don’t point your manual camera at a partially chipped sun unless the lens is protected by a solar filter. You can purchase expensive glass solar filters or make your own using inexpensive Baader AstroSolar safety film.
The steps required to take a photo of a partial solar eclipse are a little more involved than taking a standard selfie, but you can practice ahead of time whenever the sun is clearly visible. “Adjust focus and set exposure manually” Karl Heilman, a New York-based photographer who teaches solar eclipse photography workshops. He recommends using an aperture of f/8-11, a shutter speed of 1/800, and ISO 100.
Also, be careful not to spend all your time fiddling with your camera. “As much as you want to photograph the event, put down your camera and take the time to take it in, because this is one of the most amazing things you’ll ever see,” says Mezur.
New photos from the NASA/ESA Hubble Space Telescope show nearby irregular galaxy UGC 5829, also known as the Spider Galaxy.

UGC 5829 It is located approximately 30 million light-years away in the constellation Serra.
“Although this relatively faint galaxy has not been observed very often, it has the characteristic soubliquet of a spider galaxy,” Hubble astronomers said in a statement.
“Perhaps the distorted galactic arms with glowing tips that form stars remind us of the clawed legs of arachnids.”
“Somewhat confusingly, there is another galaxy known as the Spiderweb galaxy that has a very similar nickname but is otherwise completely separate.”
“Despite the fact that this galaxy is about 300 times further away from Earth than the Spider Galaxy, it has been imaged more extensively.”
“Fortunately, the ability to accurately identify galaxies does not depend on chance names.”
“Rather, known galaxies are recorded in at least one catalog, such as the Uppsala Galaxy Catalog, and are often recorded in multiple catalogs. It has been given a name.”
“This same galaxy has been given several different names in various other catalogs,” they added.
“For example, LEDA 31923 in the Lyon-Meudon Extragalactic Database; MCG+06-24-006 in the Galactic Morphology Catalog; and SDSS J104242.78+342657.3 in the Sloan Digital Sky Survey Catalog.
“Spiderweb galaxies are not all recorded in the same catalog; each catalog is necessarily limited in scope. However, they are included in the LEDA catalog as LEDA 2826829.”
“It's clearly easier to avoid confusing the boring but unique names LEDA 31923 and LEDA 2826829 than the interesting but easily confused names Spider and Spiderweb.”
This is based on data obtained through four filters. Color is obtained by assigning different hues to each monochromatic image associated with an individual filter.
The new Hubble images taken on January 5 and 6, 2024 show many large storms and small white clouds in Jupiter’s atmosphere, indicating a lot of activity.

Jupiter’s colorful clouds create a constantly changing display of shapes and colors in its atmosphere.
The planet experiences various stormy weather patterns, including low-pressure systems, high-pressure systems, wind shear, and the Great Red Spot, the largest storm in the solar system.
Jupiter is covered by a cloud of ammonia ice crystals, about 48 km thick in an atmosphere that is tens of thousands of kilometers deep, resulting in the planet’s distinctive stripes.
The banding effect is caused by air moving at different latitudes and speeds of up to 563 km per hour.
The zones, where the atmosphere rises, are brightly colored, while the belts, where the air falls, are darker. Storms and turbulence occur when these opposing flows interact.
“The left Hubble image shows the iconic Great Red Spot prominently in Jupiter’s atmosphere,” stated Hubble astronomers.
“To the lower right is a feature known as Red Spot Junior, a high-pressure system resulting from storms in previous years.”
“This year, it appears to be turning red again, possibly due to compounds like sulfur and phosphorus.”
“In the right image, storm activity is visible in the opposite hemisphere, with two distinct storm systems rotating in opposite directions.”
These storms are expected to pass each other as they repel through their rotations.
“The presence of many storms and clouds in Jupiter’s atmosphere indicates a high level of activity,” said Dr. Amy Simon, OPAL project leader and astronomer at NASA Goddard Space Flight Center.
“Despite its small size, Jupiter’s moon Io shows volcanic activity, visible through Hubble’s sensitivity to blue and violet wavelengths.”
NASA has released a surprising new image of the little-known dwarf galaxy LEDA 42160 taken by the NASA/ESA Hubble Space Telescope.
This Hubble image shows dwarf galaxy LEDA 42160 located 53.5 million light-years away in the constellation Virgo. Image credit: NASA / ESA / Hubble / M. Sun.
Also known as MCG+02-32-161, VCC 1725, ALFALFA 3-327, or AGC 220849, this galaxy is a member of a massive galaxy cluster called the Virgo Cluster.
“LEDA 42160 is one of many astronomers to force their way through the relatively dense gas in the Virgo cluster,” Hubble astronomers said.
“The pressure exerted by this intergalactic gas, known as the Ram pressure, has a dramatic effect on star formation in LEDA 42160, which is currently being studied using Hubble.”
“LEDA 42160 falls into the following categories.” magellanic spiral galaxyIn the de Vaucouleurs galaxy classification system, it is abbreviated as Sm. ”
“Magellanic spiral galaxies can be further classified as barred galaxies (SBm), barred galaxies (SAm), and weakly barred galaxies (SABm), where the ‘bar’ refers to the elongated bar at the center of the galaxy. ”
“Generally speaking, the Magellanic Spiral Galaxy is a dwarf galaxy with only one spiral arm.”
“They are named after their prototype SBm galaxy, the Large Magellanic Cloud.”
“The Magellanic Spiral Galaxy is an interesting example of how the classification of galaxies is actually more nuanced than just spiral, elliptical, irregular, etc.”
Color images of LEDA 42160 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.
NGC604 is comparable to renowned star-forming regions in the Milky Way, like the Orion Nebula, but is significantly larger and contains more recently created stars.
This image from the NIRCam instrument in Webb’s star-forming region NGC 604 shows how stellar winds from bright, hot young stars form cavities in the surrounding gas and dust. Image credit: NASA/ESA/CSA/STScI.
NGC 604 is a star-forming region situated 2.73 million light-years away in the Triangulum Galaxy.
Also identified as RX J0134.5+3047. discovered It was discovered by German-born British astronomer William Herschel on September 11, 1784.
NGC 604 is believed to be approximately 3.5 million years old and spans about 1,300 light years in diameter.
In the recent image, near infrared camera (NIRCam) and Mid-infrared measuring instrument The (MIRI) experiment aboard NASA/ESA/CSA’s NGC 604 James Webb Space Telescope reveals cavernous bubbles and elongated filaments of gas that reveal a more detailed and complete representation of a star than ever seen before. Etched birth tapestry.
Sheltered within NGC 604’s dusty gases are more than 200 of the hottest and most massive types of stars, all in the early stages of their lives.
These types of stars include type B and type O, the latter of which can have a mass more than 100 times that of the Sun.
It is extremely rare to find such a large concentration of them in nearby space. In fact, there is no similar region within our Milky Way galaxy.
This concentration of massive stars, combined with its relatively close distance, means that NGC 604 offers astronomers the opportunity to study these objects early in their lives.
This image from NGC 604’s Webb MIRI instrument shows how large clouds of cooler gas and dust glow at mid-infrared wavelengths. Image credit: NASA/ESA/CSA/STScI.
“The most striking features in Webb’s near-infrared NIRCam images are bright red-appearing tendrils or clumps of luminescence extending from areas that appear to be open spaces or large bubbles in the nebula,” Webb astronomers said. Ta.
“Stellar winds from the brightest and hottest young stars carve out these cavities, and ultraviolet light ionizes the surrounding gas. This ionized hydrogen appears as a ghostly glow of white and blue.”
“The bright orange streaks in Webb’s near-infrared images indicate the presence of carbon-based molecules known as polycyclic aromatic hydrocarbons (PAHs).”
“This material plays an important role in the interstellar medium and in the formation of stars and planets, but its origin is a mystery.”
“If you move away from where the dust was immediately removed, a deeper red color represents hydrogen molecules. This cooler gas is the perfect environment for star formation.”
“Webb’s superior resolution also provides insight into functionality previously thought to be irrelevant to the main cloud,” they added.
“For example, the Webb image shows two bright, young stars burrowing into the dust above the central nebula, connected by a diffuse red gas.”
“These appeared as separate spots in visible-light images taken by the NASA/ESA Hubble Space Telescope.”
Webb’s observations at mid-infrared wavelengths also offer new perspectives on the region’s diverse and dynamic activities.
“MIRI observations of NGC 604 show a significantly lower number of stars,” the astronomers said.
“This is because hot stars emit much less light at these wavelengths, while large clouds of cooler gas and dust glow.”
“Some of the stars seen in this image belong to surrounding galaxies and are red supergiants. These stars are cold but very large, hundreds of times the diameter of the Sun.”
“Additionally, some of the background galaxies that appeared in the NIRCam images have also dimmed.”
“In the MIRI image, blue tendrils of material indicate the presence of PAHs.”
Eddo Hartmann, Netherlands, Finalist, Professional Competition, Landscape, Sony World Photography Awards 2024
These photos, all shortlisted for the 2024 Sony World Photography Awards, get to the heart of human vulnerability and the fragility of nature.
Eddo Hartmann was selected as a finalist in the Landscape category for his series. sacrifice zoneA remote area in Kazakhstan that was the main Soviet nuclear testing site from 1949 to 1989.
The image above shows a dosimeter measuring radiation levels at Lake Shagan in Kazakhstan. The area remains highly contaminated from around 450 nuclear tests conducted there. The featured photo (above) shows the remains of an observation tower at Russia's Opitnoye Pole, another area used for Soviet nuclear tests.
Hartmann photographed these landscapes using infrared light, whose red tint was reminiscent of radioactive contamination that is invisible to the naked eye. “Local scientists are using infrared technology to monitor the current status of contaminated sites,” he says. “Chlorophyll found in green plants reflects significant amounts of infrared radiation. The different shades of reflection provide valuable insight into the overall environmental health of a given area.”

NASA/ESA/CSA’s James Webb Space Telescope has captured new images of barred spiral galaxy NGC 1559.
This Webb image shows barred spiral galaxy NGC 1559, located approximately 32 million light-years away in the constellation Reticulata. Image credits: NASA / ESA / CSA / Webb / A. Leroy / J. Lee / PHANGS Team.
NGC 1559 is situated about 32 million light-years away in the southern constellation Rechi.
Also known as LEDA 14814, ESO 84-10, and IRAS 04170-6253, this galaxy was first observed in 1826 by Scottish astronomer James Dunlop.
NGC 1559 features extensive spiral arms filled with star formation and is receding from us at a speed of approximately 1,300 km/s.
It has a mass of around 10 billion solar masses, which may seem substantial, but it’s almost 100 times less than the mass of our Milky Way galaxy.
“NGC 1559 exhibits a massive spiral arm of active star formation moving away from us at 1,300 kilometers per second,” explained the Webb astronomers.
“Although NGC 1559 appears to be close to the Large Magellanic Cloud, one of the nearest clouds in the sky, this is merely a perspective illusion.”
“In reality, NGC 1559 is not physically near the Large Magellanic Cloud in space. It is actually isolated, lacking any nearby galactic companions or members of galaxy clusters.”
“MIRI captures the glow of interstellar dust particles that trace the interstellar medium fueling future star formation,” the astronomers elaborated.
“NIRCam reflects starlight and reveals young stars hidden behind vast amounts of dust.”
“This instrument also detects emission from ionizing nebulae around young stars.”
The image of NGC 1559 was taken by the PHANGS team as part of Webb’s observation of 55 galaxies using instruments such as the Atacama Large Millimeter/Submillimeter Array (ALMA) and the NASA/ESA Hubble Space Telescope.
“By combining Webb’s unique view of dust and stars with data from these other facilities, we can delve into the detailed processes of star birth, life, and death in galaxies across the universe. Our goal is to gain new insights into this phenomenon,” stated the researchers.
“This program is also part of a Treasury Department initiative, allowing immediate access to the data for the scientific community and the general public,” they added.
“This enables us to conduct more research at a faster pace.”

Lunar New Year is celebrated around the world, and the phases of the moon, not the calendar, mark the beginning of 2024. This year's Chinese New Year was on his February 10th.
Chinese New Year is based on the lunisolar calendar, and the year begins when the second new moon (following the winter solstice) marks the beginning of the new year. This day is considered one of the most important days in Chinese culture, and families gather together to celebrate and eat together.
This year is the Year of the Dragon, the fifth of the 12-year animal cycle in the Chinese calendar. People born in the year of the Dragon are believed to have more power, luck, and success than other animals, so China tends to have more lunar birthdays.
However, Lunar New Year is not only celebrated in China. Here's how people around the world rated this event.

On February 3, 2024, NASA's Juno spacecraft made its second close approach to Io, the fifth and third largest of Jupiter's moons. Like the previous flyby on December 30, 2023, this second pass was approximately 1,500 kilometers (930 miles) away. During the twins' flyby, the spacecraft's JunoCam instrument returned stunning high-resolution images and raw data. The flyby is designed to provide new insights into how Io's volcanic engines work and whether a global magma ocean exists beneath the volcanic moon's rocky, mountainous surface. has been done.
The JunoCam instrument aboard NASA's Juno spacecraft imaged Io, the most geologically active object in the solar system, on February 3, 2024, from a distance of approximately 7,904 km (4,911 miles) . Image credit: NASA/SwRI/MSSS.
Io is the innermost of Jupiter's four Galilean moons and the fourth largest moon in the solar system.
Its diameter is about 3,630 km (2,556 miles), making it only slightly larger than our moon.
It is the only place in the solar system other than Earth that is known to have volcanoes spewing hot lava like those on Earth.
Io has over 400 active volcanoes, which are caused by tidal heating. This is the result of a gravitational tug of war between Jupiter's gravity and the small but precisely timed gravitational pulls from Europa and Ganymede.
The moon's yellow, white, orange, and red colors are produced by sulfur dioxide, frost on its surface, elemental sulfur, and various sulfur allotropes.
The volcano was first discovered on the island of Io in 1979, and since then studies using NASA's Galileo spacecraft and ground-based telescopes have shown that eruptions and lava fountains occur constantly, forming rivers and lakes of lava. Masu.
Only 13 large eruptions were observed between 1978 and 2006, in part because fewer astronomers were scanning the moon on a regular basis.
The JunoCam instrument aboard NASA's Juno spacecraft imaged Io on December 30, 2023, from a distance of approximately 5,857 km (3,639 miles). Image credit: NASA/SwRI/MSSS.
NASA's Juno spacecraft has been monitoring Io's volcanic activity from distances ranging from about 11,000 km (6,830 miles) to more than 100,000 km (62,100 miles), providing the first view of the moon's north and south poles .
On December 30, 2023, Juno came within approximately 1,500 km of Io's surface. The orbiter made her second close flyby of the Moon on February 3, 2024.
The second flyby mainly flew over Io's southern hemisphere, but previous flybys flew over Io's northern hemisphere.
Juno captured two plumes rising above Io's horizon on February 3, 2024. These plumes were emitted from two vents from one giant volcano, or from two volcanoes located close to each other. The JunoCam instrument photographed the plume from a distance of approximately 3,800 km (2,400 miles). Image credit: NASA / JPL-Caltech / SwRI / MSSS / Andrea Luck.
“We investigate the source of Io's massive volcanic activity, whether there is a magma ocean beneath its crust, and the importance of tidal forces from Jupiter that are relentlessly squeezing this beleaguered moon. doing.”
“There are active plumes, high mountain peaks with distinct shadows, and evidence of lava lakes, some of which look like islands.”
Starting in April 2024, Juno will conduct a series of occultation experiments that will use Juno's gravity science experiments to investigate the composition of Jupiter's upper atmosphere. This provides important information about the planet's shape and internal structure.
The Hubble team has released a stunning photo of the face-on spiral galaxy ESO 420-13 taken by the NASA/ESA Hubble Space Telescope.
This Hubble image shows spiral galaxy ESO 420-13 facing forward. Image credit: NASA / ESA / University of Virginia A. Evans / Gladys Kober, NASA and The Catholic University of America.
ESO420-13 It is a spiral galaxy located south of the constellation Eridanus.
This galaxy, also known as LEDA 14702, IRAS 04118-3207, or 2MASX J04134969-3200252, Seyfert Galaxy.
“Dark dust lanes are visible against the backdrop of the glow of the galaxy's many stars,” Hubble astronomers said in a statement.
“About 10% of all galaxies in the universe are thought to be Seyfert galaxies.”
“They are typically spiral galaxies and have very bright nuclei, the result of a supermassive black hole at their center accreting large amounts of radiation-emitting material.”
“The centers of these active galaxies are the brightest when observed with light outside the visible spectrum.”
“Galaxies containing active galactic nuclei of this type are often so bright that the glow of the nucleus washes out the host galaxy itself.”
“But the Seyfert galaxy is unique because the galaxy itself is also visible.”
“In the case of ESO 420-13, we can enjoy the galaxy's almost perfectly round disk, brighter core, and swirling dark dust filaments.”
Astronomers observed ESO 420-13 as part of their research. bright infrared galaxy (LIRG).
“These galaxies are known to be very bright in the infrared part of the spectrum,” the researchers said.
“Galaxy interactions trigger new star-forming regions in LIRG that become extremely bright in infrared light.”
Although water striders are small insects, they have an amazing ability to withstand the impact of raindrops that are tens of times heavier than themselves. Slow-motion video of being crushed by water reveals tricks to avoid being crushed by water, including how to ride a water jet, shoot into the air and somersault before landing. There is.
As their name suggests, water striders can be found walking along the surface of ponds, lakes, and rivers around the world. They have long legs covered in microscopic hairs that trap air and help the insect float in water.
“One day I saw them skating by the water and thought, ‘What do they do when it rains?'” andrew dickerson at the University of Tennessee. The weight of a raindrop is more than 40 times that of an adult water strider. “How do they survive? Submerged or thrown into the air?” he added.
To investigate, Dickerson and his colleagues placed several water striders in a glass aquarium filled with water, applied droplets of water, and recorded the creatures’ reactions on slow-motion video.
The researchers noticed that when raindrops hit insects on the water’s surface, the insects initially remained unharmed because of their low density. However, it was dragged into the resulting impact crater. The crater’s collapse then spewed out a stream of water that returned to the surface, taking the insects with it.
In a few cases, the researchers witnessed water striders jumping from the water jets before they returned to the surface. “It was so beautiful. You could see it do backflips out of that jet,” Dickerson says.
However, if the water strider cannot escape from the jet of water, it will be sucked back down. Luckily, their hairy, water-repellent feet allowed them to float and swim back to the surface.
“This is the equivalent of them surviving when we get hit by a car, and in some cases going through a very acrobatic journey in the process,” Dickerson said. .
These exquisite images show starlings swirling and swooping to create dramatic cloud-like flocks known as murmurs.Photographer Seiren SolcareBest known for his portraits of Björk and Paul McCartney, these are from his new photo collection.
As a child growing up in southern Denmark near the Wadden Sea, Solker was fascinated by the murmurs of starlings. Returning several years later, he witnessed large flocks of these birds being attacked by peregrine falcons. “The shapes and formations the flock created to ward off attacking birds of prey amazed me. They were beautiful and dramatic, like ink paintings or calligraphy,” he says.

“I believe that patterns in nature speak to us as humans on a deep and universal level,” Solkar says. “Experiencing these pure forms creates joy and recognition. To me, they seem to form a kind of language that many people can relate to. We want to inspire a deeper connection with ourselves.”
These images are featured in his new book starlingIt is a sequel. black sun. Solkær's photo is National Nordic MuseumSeattle, through March 10.
In the deep waters surrounding Romblon Island in the Philippines, a small translucent moray eel larva spins its body into the shape of a heart. Photographer Liang Hu took this magical photo 28 meters below the water's surface during a night dive.Pictured are some of our latest winners Close-up Photographer of the Year competition.
“I was so lucky to be able to capture this moment on camera,” Fu said in a statement. “The eel stayed at that depth for less than 10 seconds before swimming down and disappearing into the darkness.”

When I looked up at the sky, I saw a nuthatch (Citta Europaea) is flying among the trees in the Hungarian forest. These small, short-tailed birds are found throughout Europe and can be identified by their long blue bills, black eye stripes, and bluish-gray upper body. To take this photo, photographer Csaba Darozzi placed her GoPro camera inside a hollow tree stump and placed a sunflower nearby to lure wildlife.

The dazzling, colorful eggs of a female fairy shrimp can be seen in this close-up photo taken by German biologist René Krekels. This marine creature can be found in seasonal wetlands and highly saline lakes around the world, from the world's hottest deserts to the frigid climates of Antarctica. Fairy shrimp take 18 days to mature from hatching and have a lifespan of only a few months.

Gerhard Vlczek captured a fluorescent cross-section of European beach glass (Ammophila arenaria) through a microscope. The bright orange-red tubes are vascular bundles that transport food and water through the grass and encase the green tissue. In this shot, Vlcek sliced
Two spiral galaxies, NGC 6040 and NGC 6039, have merged on the right side of this Hubble image. NGC 6039 is circular when viewed from the front. NGC 6040 appears to be before the first one. In the lower left corner of the frame, elliptical galaxy NGC 6041, the central member of the galaxy cluster in which Arp 122 resides, is visible as light emanating from a point. This color image was created in both the visible and infrared regions of the spectrum using Hubble's Altitude Survey Camera (ACS) and the Dark Energy Camera mounted on NSF's Victor M. Blanco 4-meter Telescope at Cerro Tololo Inter. Created from separate exposures taken in the area. -American Observatory of Chile. Four filters were used to sample different wavelengths. Color is obtained by assigning different hues to each monochromatic image associated with an individual filter. Image credits: NASA / ESA / Hubble / J.

Alp 122 It is located in the constellation Hercules, approximately 570 million light years from Earth.
This system consists of two galaxies: a tilted and distorted spiral galaxy; NGC6040 and the spiral galaxy in front of me NGC6039.
“Galaxy collisions and mergers are highly energetic and dramatic events, but they occur on very slow timescales,” Hubble astronomers said in a statement.
“For example, our Milky Way galaxy is on a colliding orbit with its nearest galactic neighbor, the Andromeda galaxy, but it will still be four billion years before these two galaxies actually meet. ”
“The process of collision and fusion will not end soon either; it may take hundreds of millions of years to unfold.”
“These collisions take a very long time because they have very long distances.”
“Galaxies are composed of stars and their solar systems, dust and gas,” the researchers added.
“Over time, the structures of two (or more) colliding galaxies may change completely, eventually forming a single, merged galaxy.”
“That could be the result of the collision seen in this image.”
“Galaxies resulting from mergers are thought to have regular or elliptical structures because the merger process destroys more complex structures (such as those observed in spiral galaxies).”
“It will be interesting to see what Arp 122 will look like once this collision is complete, but that won't happen for a long time.”
Ever wanted to visit another world? Mars, one of our closest celestial neighbors, is an astonishing 225 million kilometers from Earth, a distance that would take over 1,000 years to walk.
But guess what? Many things on Earth look exactly like Mars; that’s what this year’s winner of the Royal Society Publishing Photography Competition proved. Although this photo looks like a snapshot of an extraterrestrial plant, it actually shows a group of Smile mold growing in a lush garden in the UK.
But the other pictures in the collection are equally amazing. From a crystal forest to a temporary rift and jellyfish elevator, the images capture strange scientific phenomena.

Many of the photos in the 2023 competition were taken in locations where the Northern Lights are rare, such as south Wales, and are captured in Matthew Brown's photography. Goreuadau's Goggled (Main image). The name translates to 'lights of the north' in Welsh and images show local landmark Paxton's Tower lit up. “It's rare to see the aurora borealis this far south,” Brown said. “For more than an hour, the horizon beyond the clouds cast shades of green and pink. But for one brief but magical moment, the sky burst
