Remains of a modern glacier found near Mars' equator implies water ice possibly present at low latitudes on Mars even today      (via sciencedaily.com) 

Scientists revealed the discovery of a relict glacier near Mars' equator. Located in Eastern Noctis Labyrinthus at coordinates 7° 33' S, 93° 14' W, this finding is significant as it implies the presence of surface water ice on Mars in recent times, even near the equator. This discovery raises the possibility that ice may still exist at shallow depths in the area, which could have significant implications for future human exploration.

Mix-and-match kit could enable astronauts to build a menagerie of lunar exploration bots      (via sciencedaily.com) 

The Walking Oligomeric Robotic Mobility System, or WORMS, is a reconfigurable, modular, multiagent robotics architecture for extreme lunar terrain mobility. The system could be used to assemble autonomous worm-like parts into larger biomimetic robots that could explore lava tubes, steep slopes, and the moon's permanently shadowed regions.

Webb Telescope captures rarely seen prelude to supernova      (via sciencedaily.com) 

The rare sight of a Wolf-Rayet star -- among the most luminous, most massive, and most briefly detectable stars known -- was one of the first observations made by NASA's James Webb Space Telescope in June 2022. Webb shows the star, WR 124, in unprecedented detail with its powerful infrared instruments. The star is 15,000 light-years away in the constellation Sagittarius.

Scientists call for global push to eliminate space junk      (via sciencedaily.com) 

As almost 200 countries agree a legally-binding treaty to protect the High Seas, a collaboration of experts in ocean plastic pollution and satellite technology has urged world leaders to learn lessons from the management of the High Seas and act now to protect Earth's orbit.

How does the immune system react to altered gravity?      (via sciencedaily.com) 

Space travel has always tested the human body by the effects of the new conditions of altered gravity on biological systems. It has long been known that continuous exposure to microgravity conditions human physiology and causes effects that compromise muscular, sensory, endocrine and cardiovascular functions. But is it also risky to be exposed to altered gravity for short periods of time?

Flat, pancake-sized metalens images lunar surface in an engineering first      (via sciencedaily.com) 

Astronomers and amateurs alike know the bigger the telescope, the more powerful the imaging capability. To keep the power but streamline one of the bulkier components, a research team created the first ultrathin, compact metalens telescope capable of imaging far-away objects, including the moon.

The planet that could end life on Earth      (via sciencedaily.com) 

A terrestrial planet hovering between Mars and Jupiter would be able to push Earth out of the solar system and wipe out life on this planet, according to a recent experiment.

Can artificial intelligence help find life on Mars or icy worlds?      (via sciencedaily.com) 

Researchers have mapped the sparse life hidden away in salt domes, rocks and crystals at Salar de Pajonales at the boundary of the Chilean Atacama Desert and Altiplano. Then they trained a machine learning model to recognize the patterns and rules associated with their distributions so it could learn to predict and find those same distributions in data on which it was not trained. In this case, by combining statistical ecology with AI/ML, the scientists could locate and detect biosignatures up to 87.5 percent of the time and decrease the area needed for search by up to 97 percent.

DART impact provided real-time data on evolution of asteroid's debris      (via sciencedaily.com) 

When asteroids suffer natural impacts in space, debris flies off from the point of impact. The tail of particles that form can help determine the physical characteristics of the asteroid. NASA's Double Asteroid Redirection Test mission in September 2022 gave a team of scientists a unique opportunity -- to observe the evolution of an asteroid's ejecta as it happened.

Hansel and Gretel's breadcrumb trick inspires robotic exploration of caves on Mars and beyond      (via sciencedaily.com) 

Future space missions likely will send robots to scout out underground habitats for astronauts. Engineers have now developed a system that would enable autonomous vehicles to explore caves, lava tubes and even oceans on other worlds on their own.

Hubble captures movie of DART asteroid impact debris      (via sciencedaily.com) 

In 2022 NASA embarked on a bold experiment to see if they could change an asteroid's velocity by smacking it with a ballistic probe -- kind of like hitting it with a hammer. This experiment was to test a potential technique to someday deflect an asteroid on a collision course to Earth. Perhaps, for the first time in the history of the universe, an intelligent planetary species sought ways to avoid its own potential extinction by threats from outer space (something the dinosaurs, who were wiped out 65 million years ago by a rogue asteroid, never evolved to accomplish).

AI draws most accurate map of star birthplaces in the Galaxy      (via sciencedaily.com) 

Scientists identified about 140,000 molecular clouds in the Milky Way Galaxy from large-scale data of carbon monoxide molecules, observed in detail by the Nobeyama 45-m radio telescope. Using artificial intelligence, the researchers estimated the distance of each of these molecular clouds to determine their size and mass, successfully mapping the distribution of the molecular clouds in the Galaxy in the most detailed manner to date.

Astronomers discover metal-rich galaxies in early universe      (via sciencedaily.com) 

While analyzing data from the first images of a well-known early galaxy taken by NASA's James Webb Space Telescope (JWST), astronomers discovered a companion galaxy previously hidden behind the light of the foreground galaxy -- one that surprisingly seems to have already hosted multiple generations of stars despite its young age, estimated at 1.4 billion years old.

How one of Saturn's moons ejects particles from oceans beneath its surface      (via sciencedaily.com) 

Enceladus, the sixth largest of Saturn's moons, is known for spraying out tiny icy silica particles -- so many of them that the particles are a key component of the second outermost ring around Saturn. Scientists have not known how that happens or how long the process takes. A study now shows that tidal heating in Enceladus' core creates currents that transport the silica, which is likely released by deep-sea hydrothermal vents, over the course of just a few months.
