Lovely Lichtenberg B Moon Crater | NASA's Lunar Reconnaissance Orbiter

Lovely Lichtenberg B Moon Crater | NASA's Lunar Reconnaissance Orbiter

Overhead view of Lichtenberg B—a beautifully preserved simple impact crater, located northwest of Aristarchus Plateau in Oceanus Procellarum on the western edge of the Moon's near side.

NASA Lunar Reconnaissance Orbiter Narrow Angle Camera (NAC) view of Lichtenberg B crater.

This year, NASA's Lunar Reconnaissance Orbiter (LRO) celebrates its 15th anniversary orbiting the Moon. This mission has given scientists the largest volume of data ever collected by a planetary science mission at NASA. LRO provided these images of Lichtenberg B—a beautifully preserved young impact crater. Rock outcrops in the upper portion of the crater wall are due to the successive thin lava flows that filled Oceanus Procellarum more than 3 billion years ago. The crater is approximately 5 km in diameter, north is up, Sun is from the south-southwest.
 
The rim of this crater is circular and sharp-edged, with negligible wear. On the inner sides the loose material has slid to the base, forming a ring of scree (small loose stones) about the interior floor. The crater rim and interior floor exhibit a relatively high albedo (light reflections). This usually indicates a younger crater that has not been darkened by space weathering.

The lack of atmosphere on the Moon can have its benefits. For example, without an atmosphere, there are few processes to degrade landforms. On Earth, rain and wind are major causes of erosion, but on the Moon, those causes are absent. Erosion on the Moon is due to impacts that cause shaking and can demolish other craters during formation and to gravity pulling material downslope. In the case of Lichtenberg B, gravity has not yet rendered the crater smooth and subdued, and there are few impacts nearby, much less any that could have affected the morphology of the crater, as Lichtenberg B appears younger than its neighbors. On the downside, the lack of atmosphere means that space weathering is more efficient on the Moon, and fresh, highly reflective crater ejecta darkens over time. However, since Lichtenberg B's ejecta deposit is still bright, it is quite young.

Crisp morphology and a highly reflective ejecta deposit make Lichtenberg B stand out from many nearby impact craters. This exquisitely preserved crater is located to the northwest of Aristarchus Plateau in Oceanus Procellarum, a vast mare unit littered with impact craters and wrinkle ridges. The ejecta deposit is particularly interesting because it displays a wrinkled texture with structures that resemble dunes. How do these structures form? What makes Lichtenberg B's ejecta deposit different from other craters that lack these dune-like structures? It turns out that Lichtenberg B is not alone. Scientists have observed these same features at Linné Crater and are in the process of determining how they formed.

The NGC 3640 Galaxy Group: Wide-field view | ESO

The NGC 3640 Galaxy Group: Wide-field view | ESO


The Very Large Survey Telescope (VST) has captured here an entire zoo of galaxies, filling the empty void of space. At the center of this varied and colorful collection, is elliptical galaxy NGC 3640, situated just above its smaller galactic neighbor NGC 3641. Astronomers are especially interested in the way these two interact with each other, studying their joint history through their populations of ancient clusters of stars.

Distance: 88 million light-years

Throughout their extremely long lifetime, galaxies change. As they soar through space, they may steal gas and stars from other galaxies, or even engulf and merge with them. After these events, galaxies can become distorted, as exemplified by the misshaped NGC 3640 and the diffuse light around it. The galaxy is then left with ‘scars’ that hint at a violent past. Astronomers can use these to know its past and present history.

To trace the history behind this galaxy and its smaller companion, a team of astronomers at the Italian National Institute for Astrophysics used the VST to analyze their globular clusters, spherical and compact aggregations of stars bound by gravity. These usually contain examples of the first stars created within a galaxy and can therefore act as fossil markers, revealing the galaxy’s history, even after merging events.

The results confirm that NGC 3640 has engulfed other galaxies before, an ominous sign for the smaller galaxy now in its path, NGC 3641. Yet, this small galactic underdog shows a distinct lack of distortions in its shape or the globular clusters within. This suggests that their interaction, while fast, is not happening close enough for NGC 3640 to pose a threat. NGC 3641 might be safe . . . for now.

Elliptical Galaxy NGC 3640: Not too close encounters of the galactic kind | ESO


This picture shows NGC 3640, an unusual elliptical galaxy 88 million light-years away. The image, taken with the VLT Survey Telescope hosted at the European Southern Observatory’s Paranal Observatory, reveals a menagerie of galaxies of all shapes and sizes, ranging from slight blue smudges to the fried-egg shape of NGC 3640. However, amidst this colorful cosmic neighborhood, one thing stands out—'this egg has a double yolk': a smaller galaxy that might be too close for its comfort.

Galaxy UGC 5460 in Ursa Major: Supernovae & Luminous Blue Variables? | Hubble

Galaxy UGC 5460 in Ursa Major: Supernovae & Luminous Blue Variables? | Hubble

The sparkling spiral galaxy gracing this NASA/European Space Agency Hubble Space Telescope picture is UGC 5460. It sits about 60 million light-years away in the constellation Ursa Major. This image combines four different wavelengths of light to reveal UGC 5460’s central bar of stars, winding spiral arms and bright blue star clusters. Also captured in the upper left-hand corner of this image is a far closer object: a star just 577 light-years away in our own galaxy.

UGC 5460 has hosted two recent supernovae named SN 2011ht and SN 2015as. It is because of these two stellar explosions that Hubble targeted this galaxy, collecting data for three observing programs that aim to study kinds of supernovae. 

SN 2015as was what is known as a core-collapse supernova: a cataclysmic explosion that happens when the core of a star far more massive than the Sun runs out of fuel and collapses under its own gravity, initiating a rebound of material outside the core. Hubble observations of SN 2015as will help researchers understand what happens when the expanding shockwave of a supernova collides with the gas that surrounds the exploded star.

SN 2011ht might have been a core-collapse supernova as well, but it could also be an impostor called a luminous blue variable. Luminous blue variables are rare stars that experience eruptions so large that they can mimic supernovae. Crucially, luminous blue variables emerge from these eruptions unscathed, while stars that go supernova do not. Hubble will search for a stellar survivor at SN 2011ht’s location, and the explosion’s identity may be revealed at last.

Image Description: A spiral galaxy seen close to face-on. The center of its disc is a bright, pale yellowish oval shape. Spiral arms extend from either side of the oval through the disc on irregular paths. They are marked throughout by bright bluish-white patches of stars. Distant background galaxies appear as small orangish blobs around the spiral galaxy. In the top-left corner a nearby star shines brightly, spikes radiating from it.

Planet Jupiter Flyby: Perijove 11 | NASA Juno Mission

Planet Jupiter Flyby: Perijove 11 | NASA Juno Mission

Here comes planet Jupiter. NASA's robotic spacecraft Juno is continuing on its highly elongated orbits around our Solar System's largest planet. This video is from perijove 11 in early 2018, the eleventh time Juno passed near Jupiter since it arrived in mid-2016. This time-lapse, color-enhanced video covers about four hours and morphs between 36 JunoCam images. The video begins with Jupiter rising as Juno approaches from the north. As Juno reaches its closest view—from about 3,500 kilometers over Jupiter's cloud tops—the spacecraft captures the great planet in tremendous detail. Juno passes light zones and dark belts of clouds that circle the planet, as well as numerous swirling circular storms, many of which are larger than hurricanes on Earth. After the perijove, Jupiter recedes into the distance, then displaying the unusual clouds that appear over Jupiter's south. To get desired science data, Juno swoops so close to Jupiter that its instruments are exposed to very high levels of radiation.

Each perijove passes near a new part of Jupiter's cloud tops. A perijove indicates the point in the Juno spacecraft's orbit when it comes closest to planet Jupiter's center. If we measure by volume, approximately 1,300 Earths could fit inside Jupiter.

The Jet Propulsion Laboratory (JPL), a division of Caltech in Pasadena, California, manages the Juno mission for the principal investigator, Scott J. Bolton, of the Southwest Research Institute in San Antonio. Juno is part of NASA’s New Frontiers Program. This is managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington. Lockheed Martin Space in Denver built and operates the spacecraft.

Planet Mars: Iridescent Clouds at Twilight | NASA's Curiosity Rover

Planet Mars: Iridescent Clouds at Twilight | NASA's Curiosity Rover

NASA’s Curiosity Mars rover captured these drifting noctilucent, or twilight, clouds on Jan. 17, 2025, the 4,426th Martian day, or sol, of Curiosity’s mission. This looping clip has been sped up about 480 times. The white plumes falling out of the clouds are carbon dioxide ice that would evaporate closer to the Martian surface.

Studying the colors in iridescent clouds tells scientists something about particle size within the clouds and how they grow over time. These clouds were captured as part of a seasonal imaging campaign to study noctilucent, or “night-shining” clouds. While the Martian clouds may look like the kind seen in Earth’s skies, they include frozen carbon dioxide, or dry ice. Sometimes these clouds even create a rainbow of colors, producing iridescent, or “mother-of-pearl” clouds. Too faint to be seen in daylight, they are only visible when the clouds are especially high and evening has fallen.

Martian clouds are made of either water ice or, at higher altitudes and lower temperatures, carbon dioxide ice. Mars’ atmosphere is more than 95% carbon dioxide. The latter are the only kind of clouds observed at Mars producing iridescence, and they can be seen near the top of the new images at an altitude of around 37 to 50 miles (60 to 80 kilometers). They are also visible as white plumes falling through the atmosphere, traveling as low as 31 miles (50 kilometers) above the surface before evaporating because of rising temperatures. 

Dawn of Twilight Clouds
Twilight clouds were first seen on Mars by NASA’s Pathfinder mission in 1997; Curiosity did not spot them until 2019, when it acquired its first-ever images of iridescence in the clouds. This is the fourth Mars year the rover has observed the phenomenon that occurs during early fall in the southern hemisphere.

Mark Lemmon, an atmospheric scientist with the Space Science Institute in Boulder, Colorado, led a paper summarizing Curiosity’s first two seasons of twilight cloud observations. It was published late last year in Geophysical Research Letters. “I’ll always remember the first time I saw those iridescent clouds and was sure at first it was some color artifact,” he said. “Now it’s become so predictable that we can plan our shots in advance; the clouds show up at exactly the same time of year.”

Each sighting is an opportunity to learn more about the particle size and growth rate in Martian clouds. This, in turn, provides more information about the planet’s atmosphere.

Cloud Mystery
One major mystery is why twilight clouds made of carbon dioxide ice have not been spotted in other locations on Mars. Curiosity, which landed in 2012, is on Mount Sharp in Gale Crater, just south of the Martian equator. Pathfinder landed in Ares Vallis, north of the equator. NASA’s Perseverance rover, located in the northern hemisphere’s Jezero Crater, has not seen any carbon dioxide ice twilight clouds since its 2021 landing. Lemmon and others suspect that certain regions of Mars may be predisposed to forming them.

A possible source of the clouds could be gravity waves, he said, that can cool the atmosphere: “Carbon dioxide was not expected to be condensing into ice here, so something is cooling it to the point that it could happen. But Martian gravity waves are not fully understood and we’re not entirely sure what is causing twilight clouds to form in one place but not another.”

NASA’s Curiosity Mars rover captured these drifting noctilucent, or twilight, clouds on Jan. 17, 2025, the 4,426th Martian day, or sol, of Curiosity’s mission.

Shenzhou-19 Crew Reaches Mission Midpoint | China Space Station

Shenzhou-19 Crew Reaches Mission Midpoint | China Space Station

China's Shenzhou-19 crew has reached the halfway point of their space mission with substantial progress made in station maintenance, in-orbit training, and crucial scientific experiments.

Last week, crew members Cai Xuzhe, Song Lingdong and Wang Haoze used their own bodies to carry out tests and collect data for a study on how long-term spaceflight can impact human muscles, particularly for typical movement patterns. Researchers on the ground will analyze data collected at various stages of the mission.

Similarly, the crew has completed tests designed to study how certain medications move through the body during spaceflight. The experimental data obtained will be used to study the changes in fine motor control and cognitive mechanisms under microgravity conditions, as well as to provide guidance for in-orbit medication.

Meanwhile, experiments in fields like materials science and combustion science are proceeding as planned. The crew has completed tasks including cleaning samples from non-container experimental chambers, performing maintenance on axis mechanisms and electrodes, and venting waste gas from the lab's combustion cabinet.

Crew members have also been providing data that will help ensure the smooth operation of future missions, filling out questionnaires and recording videos to provide feedback on the station's habitability and the practicality of its facilities.

They have also conducted a range of measurements on the station's internal environment, including personal noise exposure levels, acoustic environment monitoring, gas detection, and wind speed measurements.

To ensure their health throughout the mission, the crew has completed various medical check-ups, such as dynamic heart rate and blood pressure monitoring, body mass measurements, and hearing tests.

The Shenzhou-19 spaceflight the Tiangong space station launched on October 30, 2024 for a six-month mission, prior to the end of the previous mission, Shenzhou 18.

"Orion's Finger" in Nearby Giant Nebula Messier 42

"Orion's Finger" in Nearby Giant Nebula Messier 42

Astrophotographer StrongmanMike2002: "Over many years now, when viewing wider field shots of M42, my eye has often been drawn to this finger shaped bit of nebula. A regular thought over the years has been. I've never seen a close up shot of this cool little globule, I should shoot it one day . . . so, finally, ta daaah!"

Globules are dense dust clouds generally associated with large hydrogen-emitting star-formation regions that give off the glowing light of hydrogen gas.

A pareidolia is an optical illusion that makes us see a familiar pattern, where there is none. 

Pareidolia: Dictionaries describe this term as a human tendency to see recognizable shapes in objects or data that are otherwise not familiar to us.

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula in the Milky Way situated south of Orion's Belt in the constellation of Orion, and is known as the middle "star" in the "sword" of Orion. It is one of the brightest nebulae and is visible to the naked eye in the night sky with an apparent magnitude of 4.0. It is 1,344 ± 20 light-years (412.1 ± 6.1 pc) away and is the closest region of massive star formation to Earth. Observations of the nebula have revealed approximately 700 stars in various stages of formation within it. M42 is estimated to be 25 light-years across. It has a mass of about 2,000 times that of the Sun.

Searching for Scrub Jays: A "Far Out" Mini Episode | NASA Kennedy

Searching for Scrub Jays: A "Far Out" Mini Episode | NASA Kennedy

Kennedy Space Center is known for launching rockets into our cosmos, but it is also home to an expansive wildlife refuge and national seashore where more than 1,200 plant and wildlife species reside. Its 144,000 acres are teaming with creatures you might expect, such as alligators, snakes and eagles, and those you may not know as well like the endangered scrub-jay, tortoise and horseshoe crab.

In this mini-episode of "Far Out," viewers will meet people on the environmental team that are responsible for ensuring the wildlife remains protected and thriving at the space center.

A Stellar Bouquet for Valentine's Day: Nebula 30 Doradus | NASA Chandra

A Stellar Bouquet for Valentine's Day: Nebula 30 Doradus | NASA Chandra



A bouquet of thousands of stars in bloom has arrived. This composite image contains the deepest X-ray image ever made of the spectacular star forming region called 30 Doradus.

By combining X-ray data from NASA’s Chandra X-ray Observatory with optical data from the Hubble Space Telescope, infrared data from Spitzer, and radio data from ALMA, this stellar arrangement comes alive.

Otherwise known as the Tarantula Nebula, 30 Doradus is located about 160,000 light-years away in a small neighboring galaxy to the Milky Way known as the Large Magellanic Cloud, or LMC for short. As one of the brightest and crowded star-forming regions close to Earth, 30 Doradus is a frequent target for scientists trying to learn more about how stars are born.

With enough fuel to have powered the manufacturing of stars for at least 25 million years, 30 Doradus is the most powerful stellar nursery in the local group of galaxies that includes the Milky Way, the LMC, and our neighboring Andromeda galaxy.

The massive young stars in 30 Doradus send cosmically strong winds out into space. Along with the matter and energy ejected by stars that have previously exploded, these winds have carved out an eye-catching display of arcs, pillars, and bubbles.

A dense cluster in the center of 30 Doradus contains the most massive stars astronomers have ever found, each only about one to two million years old. For comparison, our Sun is over a thousand times older with an age of about 5 billion years.

This new image includes the data from a large Chandra program that involved about 23 days of observing time, greatly exceeding the 1.3 days of observing that Chandra previously conducted on 30 Doradus. The roughly 3,600 X-ray sources detected by Chandra include a mixture of massive stars, double-star systems, bright stars that are still in the process of forming, and much smaller clusters of young stars.

There is a large quantity of diffuse, hot gas seen in X-rays, arising from different sources including the winds of massive stars and from the gas expelled by supernova explosions. This data set will be the best available for the foreseeable future for studying diffuse X-ray emission in star-forming regions.
