Mars' Seasonal Frost Could Briefly Host Liquid Water

Universe Today - Wed, 07/30/2025 - 8:58pm

What can brine (extra salty) water teach scientists about finding past, or even present, life on Mars? This is what a recent study published in Communications Earth & Environment hopes to address as a researcher from the University of Arkansas investigated the formation of brines using 50-year-old data. This study has the potential to help researchers better understand how past data can be used to gain greater insights on the formation and evolution of surface brines on the surface of Mars.

Seasonal Frosts Could Lead to Patches of Briny Water on Mars' Surface

Universe Today - Wed, 07/30/2025 - 8:58pm

Los Angeles CA (SPX) Jul 22, 2025 Recent research led by Vincent Chevrier of the University of Arkansas offers new evidence that brines-salt-rich liquid water-could form on the Martian surface under specific seasonal conditions. Drawing on decades of research, Chevrier used atmospheric data from NASA's Viking 2 lander alongside advanced computer simulations to demonstrate that seasonal frost could briefly melt, creating small qu

The Universe's Brightest Flash Reveals the Secrets of Cosmic Jet

Universe Today - Wed, 07/30/2025 - 8:58pm

Scientists studying the brightest gamma ray burst ever recorded have discovered evidence that these explosions produce complex, layered jets rather than simple uniform beams. This remarkable finding helps solve a long standing puzzle about how the universe's most powerful explosions work and opens new possibilities for observing similar events under challenging conditions.
