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.

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.

Hitting nuclei with light may create fluid primordial matter      (via sciencedaily.com) 

A new analysis supports the idea that photons colliding with heavy ions create a fluid of 'strongly interacting' particles. The results indicate that photon-heavy ion collisions can create a strongly interacting fluid that responds to the initial collision geometry and that these collisions can form a quark-gluon plasma. These findings will help guide future experiments at the planned Electron-Ion Collider.

A surprising way to trap a microparticle      (via sciencedaily.com) 

New study finds obstacles can trap rolling microparticles in fluid. Through simulations and experiments, physicists attribute the trapping effect to stagnant pockets of fluid, created by hydrodynamics. Random motions of the molecules within the fluid then 'kick' the microroller into a stagnant pocket, effectively trapping it.
