Close-up: Giant Elliptical Galaxy NGC 4889 in The Coma Galaxy Cluster | Hubble

This image shows the elliptical galaxy NGC 4889, also known as Caldwell 35, in front of hundreds of background galaxies, and deeply embedded within the Coma galaxy cluster. Well-hidden from human eyes, there is a gigantic supermassive black hole at the center of the galaxy.

While looking at this image, you have unwittingly become an intergalactic time traveler! NGC 4889 is a galaxy that is truly far, far away—roughly 300 million light-years, or about 1,750,000,000,000,000,000,000 miles. That means the light from NGC 4889 that reaches Earth today is 300 million years old. By observing NGC 4889, the most distant object in the Caldwell catalog, we have the opportunity to peer back in time and see its corner of the cosmos as it was long ago.

NGC 4889, another of astronomer William Herschel’s discoveries, is a giant elliptical galaxy, the largest and brightest galaxy near the center of this Hubble image. It is accompanied by other members of the Coma cluster of galaxies, and is set against a backdrop of hundreds of even more distant galaxies. (One bright star on the right side of the image, and a dimmer star above it, belong to our own galaxy.)

Scientists believe NGC 4889 is about two and a half times larger than the Milky Way. Hidden in the heart of this tranquil-seeming galaxy lies a supermassive black hole. With a mass 21 billion times greater than the Sun, it is the most colossal black hole ever discovered. (For comparison, the black hole at the center of our galaxy is thought to be 4 million times more massive than the Sun.)

Black holes usually spark visions of stars and planets hurtling into the inky blackness of a tornado-like vortex, clutched in the unrelenting grip of unseen forces. While NGC 4889’s black hole used to feed on material in its younger years, astronomers believe its galactic buffet has run out and it has stopped feeding. Not only are stars not being sucked in, brand new stars are actually forming and orbiting peacefully about the black hole.

This image was taken with Hubble's Advanced Camera for Surveys in visible and infrared light. With a magnitude of 11.5, NGC 4889 is best seen using a large telescope under dark skies. As in the Hubble image, a number of fainter galaxies can be seen accompanying NGC 4889 in the field of view. From the Northern Hemisphere, late spring is the ideal time to view the galaxy, which is located in the constellation Coma Berenices. From the Southern Hemisphere, look for it in the late autumn.

NASA's Artemis II Gravity Indicator 'Rise' Lives On | Johnson Space Center

NASA's Artemis II Gravity Indicator 'Rise' Lives On | Johnson Space Center

Attendees pose with 'Rise', a representation of the zero gravity indicator for the Artemis II Mission, during an Artemis II employee celebration event at NASA's Johnson Space Center in Houston, Texas, on June 25, 2026.

The 'Rise' Moon mascot for the Artemis II Mission flew along with the crew, carrying 5,647,889 names on their journey around the Moon. People from around the world submitted their names through the Send Your Name with Artemis campaign. These names were downloaded onto a secure digital (SD) card that was safely stored inside Rise, the zero gravity indicator designed by 3rd grader Lucas Ye from California. 

The zero gravity indicator for the Moonbound crew was selected from thousands of submissions from over 50 countries and is named “Rise.” The design was inspired by the iconic Earthrise moment from the Apollo 8 mission.

NASA's Artemis II Moon Mission took NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian Space Agency (CSA) astronaut Jeremy Hansen on a nearly 10-day journey around the Moon and back to Earth.

The Orion spacecraft successfully splashed down on April 10, 2026, in the Pacific Ocean following its journey around the Moon.

The first crewed test flight of NASA’s Artemis Program lifted off from Launch Pad 39B at the agency’s Kennedy Space Center in Florida on April 1, 2026, carrying the first astronauts to travel to the Moon in more than half a century. 

The crew completed a record-setting lunar flyby, taking them 252,756 miles at their farthest distance from Earth and 4,067 miles above the lunar surface at their closest approach. 

Under Artemis, NASA will send astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, and to build on our foundation for the first crewed missions to Mars.

Rotating the New Extremely Large Telescope | European Southern Observatory

Rotating the New Extremely Large Telescope | European Southern Observatory

This video shows how, for the first time, the structure of the European Southern Observatory's Extremely Large Telescope (ELT) in Chile as it was rotated around its vertical axis. ESO staff at the construction site, together with Ace/Cimolai’s team leading the construction of the dome and main structure, rotated the telescope first by hand by a few centimeters, and then a full rotation using auxiliary motors. While this may seem small, the entire structure currently weighs around 2500 tonnes. This will further increase up to 4600 tonnes once the mirrors and science instruments are installed. The structure rests on a layer of oil just 80 microns thin that allows the telescope to rotate smoothly. Testing this motion is thus key to ensure that this massive telescope can point at all areas of the southern sky.

Discover more about ESO’s ELT at: https://elt.eso.org/

Inside the dome, the construction of the main structure of what will be the world's largest optical and near-infrared telescope is very advanced. With the first light planned for the end of the decade, the ELT and its groundbreaking 39-meter main mirror will tackle major challenges in astronomy and, ultimately, help us understand our place in the Universe.

Chile, officially the Republic of Chile, is a country in western South America. It is the southernmost country in the world and the closest to Antarctica, extending along a narrow strip of land between the Andes Mountains and the Pacific Ocean.

Journey to Distant Galaxy Cluster MACS J0553.4-3342 in Columba | Webb Telescope

Journey to Distant Galaxy Cluster MACS J0553.4-3342 in Columba | Webb Telescope

This video takes the viewer on a journey through space to a galaxy cluster named MACS J0553.4-3342, located in the constellation Columba (the Dove).

Distance from Earth: 4 billion light years

MACS J0553.4-3342 is situated at a redshift of 0.412. Redshift is a measure of how much the cluster’s light has been stretched by the expansion of the Universe over the course of its long journey to Webb’s mirrors; this unassuming number tells us that we are seeing MACS J0553.4-3342 as it was 4.4 billion years in the past. However, for a galaxy cluster, this is relatively young. In fact, observations with the NASA/European Space Agency Hubble Space Telescope and other telescopes show a cluster still in the process of being built.

MACS J0553.4-3342 is composed of two sub-clusters—roughly equal in mass—that are actively merging. The two subclusters have already slammed through each other and traveled over one million light-years apart, but they will eventually come back together again and again until they finally merge. The construction process is messy, and MACS J0553.4-3342 is filled with extremely hot gas that radiates powerful X-rays. Each subcluster is anchored on an immensely bright and massive elliptical galaxy. These are easily identifiable as the two brightest points in the center of this scene with the largest glowing halos around them. The many smaller white elliptical galaxies are bound to one of the two subclusters by gravity, and will be incorporated into the final galaxy cluster. This image also features many foreground galaxies—spirals and dusty discs that are unrelated to MACS J0553.4-3342—and prominent bright stars in our own Milky Way galaxy.

Even mid-way through its construction, the titanic clumps of matter swirling around in this galaxy cluster have built a device that is already very useful for us here on Earth: a gravitational lens. The extreme and concentrated mass in MACS J0553.4-3342 curves light with its gravity, similar to how a glass lens bends and focuses light. In this image you can see prominent orange, stretched-out arcs alongside each of the subclusters. These arcs are images of distant background galaxies, whose light has been warped by the galaxy cluster’s gravitational pull. The arc on the left side, three bright spots joined together, is actually three images of a single background galaxy. A forest of smaller arcs and lines are scattered across the image too; such a fantastic view appears in few other places in the Universe.

Look in the right spot, however, and this galaxy cluster turns from a distorting funhouse mirror into a precision scientific device. The gravitational lensing focuses light, magnifying objects and enhancing their brightness so if they lie in exactly the right place, background galaxies and even individual stars that would have been far too faint and distant to spot will be made visible. By carefully mapping out the mass of the cluster, researchers can reconstruct where and how strongly it distorts light from our point of view, then search for serendipitously-magnified distant objects to study. The arcs we can see in MACS J0553.4-3342 already show a few galaxies from less than a billion years after the Big Bang.

The final image, taken with Webb’s Near-Infrared Camera (NIRCam), stems from a survey program named VENUS (#6882). Astronomers aimed to create a collection of deep, high-quality images of massive galaxy clusters like MACS J0553.4-3342 across a wide range of infrared wavelengths, greatly expanding the area covered by Webb’s sensitive instruments. Researchers can then scour the clusters for distant and faint objects that have been brightened through gravitational lensing, from young galaxies and low-mass black holes to supernova explosions and individual stars. Gravitational lensing has been key to many of Webb’s most dramatic discoveries in recent years, and having many more examples of it allows us to systematically study the distant past and the evolutionary stages of the galaxies, stars and black holes we see today.

Asteroid Itokawa | Japan's Hayabusa Spacecraft

Asteroid Itokawa | Japan's Hayabusa Spacecraft

Why are parts of this asteroid's surface so smooth? 

The answer seems likely to do with the dynamics of an asteroid that is a loose pile of rubble rather than a solid rock. The unusual asteroid Itokawa was visited by the Japanese spacecraft Hayabusa in 2005 that imaged and documented its unusual structure and mysterious lack of craters. Analyses of the border regions between smooth and rugged sections indicate that jostling of the asteroid might be creating segregation between large and small rocks near the surface, like the "Brazil nut" effect. 

25143 Itokawa (provisional designation 1998 SF36) is a sub-kilometer near-Earth object of the Apollo group and also a potentially hazardous asteroid. It was discovered by the LINEAR program in 1998 and later named after Japanese rocket engineer Hideo Itokawa. The peanut-shaped S-type asteroid has a rotation period of 12.1 hours and measures approximately 330 meters (1,100 feet) in diameter. Due to its low density and high porosity, Itokawa is considered to be a rubble pile, consisting of numerous boulders of assorted sizes, rather than a single solid body.

The robotic Hayabusa actually touched down on one of the smooth patches, dubbed the MUSES Sea, and collected soil samples. These samples were returned to Earth and are not only giving clues to the ancient history of this unusual asteroid, but also about the early years of our Solar System. Computer simulations show that 500-meter asteroid Itokawa may impact the Earth within the next few million years.

Flyby of Asteroid Torifune | Japan's Hayabusa2 Spacecraft

Flyby of Asteroid Torifune | Japan's Hayabusa2 Spacecraft

The Japan Aerospace Exploration Agency (JAXA) has successfully conducted a flyby of asteroid Torifune, the first asteroid exploration of the Hayabusa2 Extended Mission. On July 5, 2026, at 18:35 Japan Standard Time (JST), the Hayabusa2 spacecraft was confirmed from ground communications to be operating normally.

98943 Torifune (provisional designation 2001 CC21) is an Apollo-type near-Earth asteroid with a diameter of about 450 meters (1,500 feet). It was discovered by the Lincoln Near-Earth Asteroid Research (LINEAR) survey at Socorro, New Mexico, United States on February 3, 2001.

The asteroid explorer Hayabusa2 was launched in December 2014 onboard the H-IIA Launch Vehicle No. 26. The mission explored asteroid Ryugu, delivering samples from Ryugu to Earth on December 6, 2020. Since then, the spacecraft returned to deep space on an Extended Mission. On July 5, 2026 at around 18:30 JST, Hayabusa2 successfully performed a flyby of Torifune, the asteroid selected as the first exploration target of the Extended Mission.

Observations with the onboard scientific instruments began in mid-June with the Optical Navigation Camera—Telescopic (ONC-T) that directly imaged Torifune on June 20. Observations with the ONC-T then continued with the primary purpose to support optical-radio hybrid navigation for the spacecraft during the approach to Torifune. From about one hour before the closest approach, observations were also conducted using the Near-Infrared Spectrometer (NIRS3), Thermal InfraRed Imager (TIR), and Light Detection and Ranging (LIDAR) instruments. These observations continued until immediately before the closest approach to Torifune but could not be conducted after the spacecraft had passed the asteroid. At present, only part of the data acquired by the scientific instruments has been transmitted to Earth. The remaining data will be transmitted to the ground during future operations.

Interstellar Comet 3I/ATLAS Likely Formed in Outskirts of Old Star System | ESO

Interstellar Comet 3I/ATLAS Likely Formed in Outskirts of Old Star System | ESO

Using the European Southern Observatory’s Very Large Telescope (VLT), astronomers have studied the relative abundances of carbon and nitrogen in 3I/ATLAS, the third interstellar comet discovered so far and the brightest interstellar object ever seen. Their findings suggest that the comet likely formed in the outskirts of the disc around a star older than the Sun. This video summarizes the discovery.

Interstellar comets are icy objects formed around a star other than the Sun that occasionally wander into our Solar System. "They are sort of fossils from a planetary formation process that happened very far away, but that we get the chance to study from much closer," says astronomer Cyrielle Opitom, a researcher at the University of Edinburgh, United Kingdom. Together with Jean Manfroid and Damien Hutsemékers of the University of Liège, Belgium, Opitom led a study of 3I/ATLAS published today in Nature Astronomy.

3I/ATLAS is the third interstellar object ever discovered, after 1I/ʻOumuamua and 2I/Borisov. It was found as it was approaching the Sun, spending enough time in our Solar System for astronomers to study it in detail. While it was difficult to measure the composition of the first two interstellar objects—in the first astronomers did not detect gas and the second was too faint—this was not the case for 3I/ATLAS. Thanks to the object's unprecedented brightness, Opitom, Manfroid, Hutsemékers and their team were able to measure the comet's isotopic ratios: the relative amounts of different forms of the same element.

Using the UVES instrument on ESO's VLT, the team measured ratios of carbon and nitrogen isotopes in cyanide molecules present in the gas around the comet. These ratios are known to be a good indicator of a comet’s origin, as they are very sensitive to the physical conditions in the formation environment and are not expected to change much as the comet travels on through space.

“Unlike comets from our Solar System, this interstellar visitor carries unusually high carbon and nitrogen isotopic ratios,” explains Aravind Krishnakumar, a researcher at the University of Liège and co-author on the new study. A similar study led by Martin Cordiner at the NASA Goddard Space Flight Center, US, that was published late last month in Nature, found a similar isotopic ratio of carbon, as well as elevated levels of deuterium, also called heavy hydrogen. The study used data from the James Webb Space Telescope, a joint project of the US, European, and Canadian space agencies.

Overall, the findings by Opitom’s team indicate that the comet likely formed in the outer regions around an old, ‘low-metallicity’ star. A low-metallicity star is one with few elements heavier than helium in its composition, that is thought to have formed when the Universe was much younger—and less chemically rich—than it is now. The team suspects that 3I/ATLAS therefore originated around a star much older than the Sun. “3I/ATLAS is a really exciting opportunity to probe the composition of another planetary system, one that formed long before our Sun and Solar System even existed," says co-author Rosemary Dorsey, a researcher at the University of Helsinki, Finland. Evidence from the studies by the different teams points to 3I/ATLAS being more than twice as old as the Sun.

As 3I/ATLAS moves away from the Sun and gets progressively fainter, its observations at the VLT are also nearing their end. ESO's upcoming Extremely Large Telescope (ELT) will allow similar measurements for future interstellar objects, including those less bright than 3I/ATLAS. "The field of interstellar objects is still very new, and we do not really know what to expect. Every time a new one is discovered, we have new surprises," Opitom concludes.

The Artemis II crew reflects on their historic 10-day journey around the Moon and back to Earth at an Artemis II employee celebration event at the Lunar Receiving Park at NASA's Johnson Space Center. 

NASA's Artemis II Moon crew visited NASA's Johnson Space Center in Houston, Texas, on June 25, 2026. They participated in the dedication of the Apollo 14 Moon tree and joined an employee celebration event. The tree is a second-generation Apollo Moon tree of the loblolly pine species. The original Apollo Moon trees were grown from seeds carried aboard Apollo 14 by NASA astronaut Stuart Roosa, a former U.S. Forest Service smoke jumper. Upon return to Earth, the seeds were germinated by the Forest Service, and the resulting seedlings were planted throughout the United States and around the world.

NASA's Artemis II Moon Mission took NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian Space Agency (CSA) astronaut Jeremy Hansen on a nearly 10-day journey around the Moon and back to Earth.

The Orion spacecraft successfully splashed down on Friday, April 10, 2026, in the Pacific Ocean following its journey around the Moon.

The first crewed test flight of NASA’s Artemis Program lifted off from Launch Pad 39B at the agency’s Kennedy Space Center in Florida on April 1, 2026, carrying the first astronauts to travel to the Moon in more than half a century. 

The crew completed a record-setting lunar flyby, taking them 252,756 miles at their farthest distance from Earth and 4,067 miles above the lunar surface at their closest approach. 

Under Artemis, NASA will send astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, and to build on our foundation for the first crewed missions to Mars.

Most Ancient Quasars in the Universe Discovered | Euclid Space Telescope | ESA

Most Ancient Quasars in the Universe Discovered | Euclid Space Telescope | ESA

In March 2026, the European Space Agency's Euclid space telescope discovered 31of the most ancient quasars ever found, more than doubling the number of quasars we know of that are so old. Two of these giant, dazzling, black hole-powered galaxy cores are older than any we have seen before. These cosmic elders shone with the light of a trillion Suns back when the Universe was 670 million years old—just 5% of its current age.

Quasars are distant galaxies whose incredibly bright cores are powered by supermassive black holes. Quasars have been found with luminosities between 10 to 100,000 times that of our Milky Way galaxy, generated from an area just a few light-days to a few light-years across.

Quasars occur when immense amounts of matter fall into a supermassive black hole, spiraling around it in the form of a disk before entering. This “accretion disk” is subjected to extreme gravitational and frictional forces, causing the gas and dust to heat up to millions of degrees and become luminous, blasting out dazzling jets of material into the universe. Together, the jets and glowing disk outshine their host galaxies.
