Planet Mars: Thickly Frosted Polar Gullies | NASA's Mars Reconnaissance Orbiter

Planet Mars: Thickly Frosted Polar Gullies | NASA's Mars Reconnaissance Orbiter

Carbon dioxide frost from the past winter still thickly blankets this terrain imaged in early Martian spring. Dark blob-like surface markings show the initial hints at the coming defrosting and soon these dark marks will cover the entire scene before the frost dissipates entirely in summer.

Of special interest in this image are the gullies that are visible at regular intervals leading from the tops of the high-standing mesas to the lower terrain. During defrosting, these gullies will become active and they will host flows of a slurry of frost, gas, and underlying rocky material. The cold carbon dioxide frost temperatures mean that no liquid water is involved.

Carbon dioxide (CO₂) ice blocks on Mars may dig gullies as they slide and sublimate in the thin atmosphere. Sublimation is the transition of a substance from solid to gas without becoming liquid.

Repeated observations of these sites allow us to understand these seasonal effects on Mars and comparison to other years give us valuable insight into the variability of Mars’ current climate.

This HiRISE enhanced color camera image (less than 1 km in size) was captured by NASA's Mars Reconnaissance Orbiter (MRO) at an altitude of 251 km (~156 miles).

NASA's Mars Reconnaissance Orbiter has spent over twenty years (2006-2026) orbiting the Red Planet, collecting valuable scientific data.

Marmalade Skies over Gemini North Telescope in Hawaii

Marmalade Skies over Gemini North Telescope in Hawaii

The skies over Gemini North (left), one half of the International Gemini Observatory, in Hawai‘i, are alive with color in this image. The International Gemini Observatory is funded in part by the U.S. National Science Foundation (NSF) and operated by NSF NOIRLab. The gorgeous orange tint of the night sky seen here is due to a phenomenon called airglow. Airglow is primarily caused when sunlight excites atoms and molecules in Earth’s upper atmosphere by transferring energy to them. This excess energy is released as a particle of light called a photon. The frequency of each photon determines which captivating color will appear. It is possible to see this light with the naked eye under very dark skies, but a camera can capture it more easily. 

Arcing against this marmalade sky is the Milky Way, and beneath it, to the right, is another rarely seen phenomenon. The hazy white glow is zodiacal light, created by sunlight scattering off small interstellar dust particles leftover from the formation of our Solar System. This effect is mainly visible during evening and morning twilight along the plane of the Solar System and the zodiac constellations, thus giving this effect its name.

Long-Lived Hotspots on Supergiant Betelgeuse Star’s Bubbling Surface | ALMA

Long-Lived Hotspots on Supergiant Betelgeuse Star’s Bubbling Surface | ALMA

This is a remarkable view of the red super-giant star Betelguese in Orion. This huge star, around 800 times the size of our sun, shows huge convective bubbles on its surface. What is perhaps most remarkable here is the resolution achieved. Betelgeuse is around four thousand trillion miles away from us and appears about as large in the sky as an American dime viewed from roughly 55 miles (88 km) away.

This remarkably detailed image was obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) in the Atacama Desert of northern Chile. It reveals the uneven surface of Betelgeuse, the famous red supergiant in the constellation Orion. The observations show bright hotspots and an irregular, corrugated outline shaped by the enormous motions taking place within the star.

Located roughly 600 light-years from Earth, Betelgeuse is one of the closest red supergiants. Its immense size makes it possible for ALMA to resolve structures across its atmosphere that would remain hidden in most other stars.

The new observations were obtained in 2023 using ALMA in its longest-baseline configuration, achieving a resolution as fine as about seven milliarcseconds. They reveal an atmosphere with an average temperature of around 2300 K and at least two hotter regions, to the northeast and southwest of the stellar disk. The brightest hotspot is up to about 800 K hotter than the surrounding gas.

These structures are thought to be linked to enormous convective motions inside Betelgeuse. Hot gas rising from deeper layers can generate shocks as it reaches the star’s outer atmosphere, producing the bright and uneven features detected by ALMA.

One finding particularly surprised the researchers. When they compared the 2023 observations with similar ALMA data obtained in 2015, the prominent northeastern hotspot appeared in almost the same location and with a similar intensity. This suggests that the feature has persisted for at least seven years—considerably longer than the lifetimes of large convective structures predicted by current models.

The surface itself is also far from spherical. ALMA measured variations of up to about six percent in its apparent radius, while fainter emission extends several stellar radii into Betelgeuse’s atmosphere. Observations of molecules including silicon monoxide (SiO) and carbon monoxide (CO) reveal an even more irregular and clumpy environment surrounding the star.

The orientation of the long-lived hotspots is also intriguing in light of recent evidence for a close companion to Betelgeuse, although the observations do not establish a direct connection. Continued high-resolution observations with ALMA could reveal whether the hotspots remain fixed and how they relate to convection, mass loss, and the structure of the star’s extended atmosphere.

Betelgeuse is approaching the final stages of its evolution and will eventually explode as a supernova. “Its eventual fate as a supernova makes it fascinating to know what it actually looks like now,” says lead author Bill Dent, an astronomer at ESO.

Image Description:
A Bubbling Betelgeuse: This ALMA image shows the submillimeter surface of Betelgeuse, revealing its irregular shape and regions of hotter gas. The brightest hotspot, toward the northeast of the star, appears at nearly the same location in ALMA observations separated by more than seven years, suggesting that some structures in Betelgeuse’s atmosphere can survive considerably longer than predicted by current models of stellar convection.

Galactic Gems Glisten in New Image Gallery | NASA's Chandra X-ray Observatory

Galactic Gems Glisten in New Image Gallery | NASA's Chandra X-ray Observatory

Galaxies are cosmic gems—each with characteristics including size and shape that make them distinct. This new gallery displays a collection of galactic images from NASA’s Chandra X-ray Observatory and other telescopes.

Just as gems reveal the history of the Earth through how they were forged over billions of years, these galactic gems are a way to study our Earth’s place in our home galaxy of the Milky Way. By looking outward to other galaxies, we learn more about our own—including clues to its past and future.

Astronomers put galaxies into three main categories: spirals like our own Milky Way with arms emanating from their cores, ellipticals that are older and likely the results of mergers, and irregulars that can encompass a wide range of galactic phenomena.

For example, face-on spiral galaxies, like Messier 33 and NGC 3938, offer unobstructed views of where energetic pairs of stars and cosmic explosions live along spiral arms. Barred spirals like NGC 1672 and NGC 1385 show how central bar-shaped collections of stars, gas, and dust funnel fuel inward to ignite bursts of star formation. NGC 4725 reveals how star formation can be triggered by a collision with another galaxy. Meanwhile, edge-on views of NGC 4631 and the starburst Messier 82 showcase giant halos and superwinds of million-degree gas driven thousands of light-years into space by intense explosions of stars, enriching surrounding intergalactic space with vital elements.

Powerful, growing black holes in the cores of their host galaxies send energy outward in outbursts and jets that impact entire galaxies. In Centaurus A, Chandra and IXPE data expose a high-energy particle jet blasting tens of thousands of light-years into space from its central engine. In Messier 106, jets from the supermassive black hole heat surrounding gas to create "anomalous" spiral arms. Meanwhile, the iconic Sombrero Galaxy highlights a supermassive black hole embedded in a colossal stellar bulge, where Chandra’s X-rays map a diffuse halo of million-degree gas and hot stellar remnants surrounding its sweeping dust lanes.

The gallery also showcases galaxies undergoing extreme gravitational transformations. A direct impact in Arp 143 acts like a cosmic bullseye, creating an expanding ring galaxy and triggering waves of star birth. Violent mergers—such as NGC 3256 and the dust-shrouded starburst II Zw 096—reveal the kind of chaotic galaxy collisions that dominated the early universe and offer a preview of the Milky Way’s distant future merger with Andromeda. NGC 1569 acts as a local laboratory for studying early universe starbursts, NGC 660 showcases a rare "polar ring" galaxy where a ring of stars orbits over its poles, and Messier 90 shows a spiral galaxy plowing through the hostile Virgo Cluster, having its star-forming gas violently stripped away.

Each category is visually unique and also plays an important role in the story of the universe, just as gemstones and minerals reveal the history and composition of planet Earth.

All of the 16 new galaxies in this collection contain X-ray data from Chandra that has been collected across Chandra’s decades in space. This high-energy data has been combined with data from telescopes such as NASA’s James Webb and Hubble Space Telescopes, IXPE, Swift, NuSTAR and others both on the ground and in space.

X-rays are critical for the study of galaxies, revealing unique and important information about these cosmic building blocks. Chandra sees some of the hottest and most energetic galactic phenomena in the universe—forming a more complete picture of how galaxies live, interact, and evolve when combined with data from other types of light and telescopes.

'Fuzzy' Elliptical Galaxy NGC 4660 in the Virgo Cluster | Hubble Space Telescope

'Fuzzy' Elliptical Galaxy NGC 4660 in the Virgo Cluster | Hubble Space Telescope


Virgo cluster galaxy NGC 4660, is an elliptical located about 50 million light-years from Earth. Hubble's "eye" is so sharp that it was able to pick out the fuzzy globular clusters that at this distance, look like individual stars bunched up around the galaxies, instead of groupings of stars.

Most elliptical galaxies are composed of older, low-mass stars with a sparse interstellar medium, and they tend to be surrounded by large numbers of globular clusters. An elliptical galaxy is a type of galaxy with an approximately ellipsoidal shape and a smooth, nearly featureless image.

Gullies at the Start of Martian Spring | NASA's Mars Reconnaissance Orbiter

Gullies at the Start of Martian Spring | NASA's Mars Reconnaissance Orbiter

NASA's Mars Reconnaissance Orbiter (MRO) regularly takes repeat images of gullies to look for changes. Carbon dioxide (CO₂) ice blocks on Mars may dig gullies as they slide and sublimate in the thin atmosphere. Sublimation is the transition of a substance from solid to gas without becoming liquid.

This site is one of the most frequent monitoring sites with more than 70 images to date. It is imaged frequently due to the latitude. The gullies have a long season with carbon dioxide frost (dry ice) moving rocks and dust around the surface. In past images, we have seen many changes to the frost patterns and the underlying ground.

This image is the first one for this Mars year. However, you can already see dark spots where gas is breaking out from under the frost and taking sand and dust with it. MRO will try to take more images this year to see how the surface changes.

This HiRISE enhanced color camera image (less than 1 km in size) was captured by NASA's Mars Reconnaissance Orbiter (MRO) at an altitude of 252 km (~157 miles).

NASA's Mars Reconnaissance Orbiter has spent over twenty years (2006-2026) orbiting the Red Planet, collecting valuable scientific data.

NASA astronaut Mike Fincke is departing the agency on Wednesday after 30 years of service. Throughout his career, he flew four missions, spent 549 days in space, and completed nine spacewalks in support of the International Space Station.

“Few people have had the opportunity to shape as many chapters of NASA’s history as Mike Fincke,” said NASA Administrator Jared Isaacman. “Over a remarkable career, Mike served our nation as a pilot, engineer, astronaut, and mentor. From long-duration missions aboard the International Space Station to helping prepare the Artemis generation, his contributions have helped position NASA for what comes next. The success we’re building on today is possible because of people like Mike, who dedicated their careers to moving our space program forward and preparing the next generation to carry the mission even further. I’d like to congratulate Mike on an incredible career and thank him for his decades of service to NASA, our nation, and the countless people who had the opportunity to learn from and fly alongside him.”

He ranks fourth among NASA astronauts in accumulated time in space, and his spacewalks total 48 hours and 37 minutes. Most recently, Fincke piloted NASA’s SpaceX Crew‑11 mission that launched in August 2025 and returned in January. During the mission, he served as a flight engineer for International Space Station Expedition 73 and commander of Expedition 74.

Fincke joined NASA’s 16th astronaut class in 1996 and first flew to space in 2004 aboard Soyuz TMA‑4 in support of the space station’s Expedition 9. Serving as a science officer and flight engineer, he helped maintain station systems and performed four spacewalks. He returned to space in 2008 on Soyuz TMA‑13 as commander of Expedition 18, preparing the space station for its transition to six‑person crews at the time and completing two more spacewalks.

In 2011, Fincke flew on STS‑134, the final flight of space shuttle Endeavour. As mission specialist and robotic arm operator, he completed three spacewalks and helped deliver and install the Alpha Magnetic Spectrometer.

“Mike’s remarkable career reflects three decades of dedication to NASA’s mission and the advancement of human spaceflight,” said Vanessa Wyche, director of NASA’s Johnson Space Center in Houston. “From his time aboard the International Space Station to his commitment to mentoring the next generation, Mike has made an immense impact across our agency. His legacy of service, mentorship, and dedication to exploration will continue to inspire the generations to come.”

Throughout his career, Fincke bridged spacecraft development, flight testing, and mission operations. Early in the International Space Station Program, he helped test and integrate several of the station’s initial modules before launch. His flight experience spanned multiple generations of human spacecraft, including two missions aboard Soyuz, one aboard the space shuttle, and later piloting the SpaceX Dragon.

Fincke was a foundational contributor to NASA’s Commercial Crew Program. As chief of the Astronaut Office’s Commercial Crew Branch, he worked to ensure astronaut needs, crew safety, and human spaceflight experience informed development of the nation’s next generation of crewed spacecraft. He spent five years supporting Boeing’s Crew Flight Test program training as a crew member and backup pilot, contributing to flight software, systems integration, integrated testing, and spacecraft interfaces.

Fincke also supported station operations from the ground as a crew test support team member in Russia, a capsule communicator, or capcom, and crew procedures team lead. He helped translate complex engineering and operational requirements into clear instructions for crews working in orbit. His continuity across development, integration, mission support, and long‑duration flight gave him an end‑to‑end perspective on space station assembly and operation.

“Mike approached every assignment with experience, humility, and an unwavering focus on the mission,” said Scott Tingle, chief of the Astronaut Office at NASA Johnson. “Whether flying aboard the station, supporting crews from the ground, or helping shape the spacecraft that future crews will rely on, he consistently strengthened our team. His legacy is woven into the way we fly today.”

A native of Emsworth, Pennsylvania, Fincke holds bachelor’s degrees in aeronautics and astronautics and in Earth, atmospheric, and planetary sciences from the Massachusetts Institute of Technology, where he also studied in the Soviet Union through an exchange program with the Moscow Aviation Institute. He earned master’s degrees in aeronautics and astronautics from Stanford University and in planetary geology from the University of Houston, Clear Lake.

Fincke is a retired U.S. Air Force colonel and distinguished graduate of the U.S. Air Force Test Pilot School. He served as a space systems engineer and flight test engineer at Edwards and Eglin Air Force Bases and later as the U.S. flight test liaison to the Japanese‑U.S. XF‑2 fighter program at Gifu Air Base in Japan. He accumulated more than 2,000 flight hours in more than 30 aircraft types.

“After exactly 30 years, I am departing NASA, but I remain deeply committed to the work of exploration.” Fincke said. “NASA gave me the extraordinary privilege of serving alongside remarkable people, flying and helping develop spacecraft, and contributing to the International Space Station from its earliest days through command in orbit. I am profoundly grateful to my crewmates, the teams on the ground, our international partners, and the families who make this work possible. I am excited to carry those lessons forward and help prepare the next generation of engineers, explorers, and leaders. Together, we will return humanity to the Moon, travel to Mars, journey outward to the planets and moons beyond Earth, and someday reach for the stars – all while caring for Earth, the most beautiful planet in our solar system.”

Planet Mars: Mysterious, wind-blown features | NASA's Mars Reconnaissance Orbiter

Planet Mars: Mysterious, wind-blown features | NASA's Mars Reconnaissance Orbiter

Transverse aeolian ridges—or TAR—are mysterious, wind-blown features that are intermediate in size between ripples and much larger sand dunes.

Ripples form from hopping sand grains, and dunes form from sand grains being blown over longer distances. One hypothesis for TAR formation is that larger grains like pebbles are rolled on top of smaller ripples. Then, finer dust settles into the cracks, “inflating” the pebbles, making the TAR larger than typical ripples.

Looking between the TAR, one sees a network of ancient, beaten-up channels that were carved by water, lava, or both.

This whole area is located in Solis Planum, an interesting, tectonic terrain south of Noctis Labryinthus that generally slopes toward the south. Solis Planum is a planum on Mars which has a diameter of 1811.23 km. Its center latitude is 26.4 S and its center longitude is 270.33 E. Noctis Labyrinthus (Latin for 'Labyrinth of the Night') is a region of Mars located in the Phoenicis Lacus quadrangle, between Valles Marineris and the Tharsis upland. The region is notable for its maze-like system of deep, steep-walled valleys. 

This HiRISE enhanced color camera image (less than 1 km in size) was captured by NASA's Mars Reconnaissance Orbiter (MRO) at an altitude of 252 km (~157 miles).

NASA's Mars Reconnaissance Orbiter (MRO) has spent over twenty years (2006-2026) orbiting the Red Planet, collecting valuable scientific data. 

The University of Arizona, in Tucson, operates the High Resolution Imaging Science Experiment (HiRISE). It was built by BAE Systems in Boulder, Colorado. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate (SMD), Washington.

Shenzhou-23 Crew Advances Experiments, Health Monitoring | China Space Station

Shenzhou-23 Crew Advances Experiments, Health Monitoring | China Space Station

China's Shenzhou-23 astronauts have pressed ahead with a full slate of space science experiments, while also carrying out routine station upkeep and comprehensive health management tasks over the past week as they will mark their first three months in orbit, according to the China Manned Space Agency (CMSA).

According to the mission schedule, the three crew members of Zhu Yangzhu, Zhang Zhiyuan and Lai Ka-ying have carried out a series of hands-on scientific operations. They replaced and cleaned experimental samples, and performed electrode maintenance as well as lens cleaning. In addition, the trio completed gas cylinder replacement and vacuum pumping and exhaust removal.

On the station maintenance front, the crew conducted routine microbial monitoring aboard the space station. They collected and tested samples from cabin air, surfaces, and water systems to assess microbial growth conditions, providing critical data for in-orbit contamination prevention and control.

In terms of health management, the astronauts completed scheduled visual function assessments and non-invasive cardiac function tests, offering valuable reference data for researchers monitoring the long-term health effects of spaceflight. Meanwhile, all the three crew members have maintained regular in-orbit exercise routines and have been using specialized equipment such as bone loss countermeasure devices to mitigate the physiological impacts of microgravity.

Meanwhile, they took a well-deserved break, eating together to replenish energy, relaxing body and mind, shedding the fatigue of intense work, and recharging for the missions ahead.

China launched the Shenzhou-23 crewed spaceship on May 24, 2026. The mission includes a one-year in-orbit study designed to gather data for future long-duration human space missions.

View towards 'The Great Attractor' in Our Local Universe | ESO

View towards 'The Great Attractor' in Our Local Universe | ESO

The Great Attractor is a region of heightened gravitational attraction in the local universe. It lies in the general direction of the Norma Cluster and the Hydra–Centaurus Supercluster, approximately 150–250 million light-years from the Milky Way. Its presence was inferred from the peculiar motions of galaxies that deviate from the motion expected solely from the expansion of the universe. The Great Attractor lies in the direction of the constellations Norma and Triangulum Australe.

The term does not refer to a single galaxy, galaxy cluster, or compact astronomical object. Instead, it describes a broad concentration of matter and an associated minimum in the local gravitational-potential and velocity fields. 

This image covers a field of 0.5° x 0.5° in the Southern constellation of Norma (The Level) and in the direction of the "Great Attractor". This region is at an angular distance of about 7° from the main plane of the Milky Way, i.e. less than 15 times the width of the image shown. In this color composite, the foreground stars in the Milky Way mostly appear as whitish spots (the "crosses" around brighter stars are caused by reflections in the telescope optics). Many background galaxies are also seen. They form a huge cluster (ACO 3627) with a number of bright galaxies near the center — they stand out by their larger size and yellowish color. North is up and East is left.

Five exposures each were made in blue (B-band filter; 5 x 300 sec), red (R-band filter; 5 x 180 sec) and near-infrared (narrow-band filter centered at 816 nm; 5 x 240 sec) light and combined into a false-color composite by using blue, green, and red color for the three images, respectively. A logarithmic intensity scale is used to better show the inner as well as the outer regions of the galaxies in this field.

Wide-field view: Distant Galaxy Cluster Abell 3827 | Victor Blanco Telescope

Wide-field view: Distant Galaxy Cluster Abell 3827 | Victor Blanco Telescope


This image features Abell 3827, a galaxy cluster, about 222 million light years distant, that offers a wealth of exciting possibilities for study. Looking at this cluster of hundreds of galaxies, it is amazing to recall that until less than 100 years ago, many astronomers thought that the Milky Way was the only galaxy in the Universe. The possibility of other galaxies had been debated previously, but the matter was not truly settled until Edwin Hubble confirmed that the Great Andromeda Nebula was in fact far too distant to be part of the Milky Way. The Great Andromeda Nebula became the Andromeda Galaxy, and astronomers recognized that our Universe was much, much larger than humanity had imagined. We can only imagine how Edwin Hubble—after whom the Hubble Space Telescope was named—would have felt if he had seen this spectacular image of Abell 3827.

Abell 3827 is a rich cluster of galaxies located near the center of the Great Attractor; it is about 222 million light years distant. Although it is both nearby and bright, it is difficult to observe because it is located in the Zone of Avoidance, a region near the plane of the Milky Way. Consequently, the cluster is severely obscured by interstellar dust at optical wavelengths.

This wide-field image was collected as part of the Local Volume Complete Cluster Survey (LoVoCCS), a program investigating 107 nearby galaxy clusters. It took advantage of an astrophysical phenomenon called weak gravitational lensing to measure the mass and matter distributions of these clusters.
