Astronomers using the James Webb Space Telescope have identified a possible jellyfish galaxy about 12 billion light-years away. Named COSMOS2020-635829, it shows tentacle-like streams of gas and stars trailing off one side—likely formed through ram pressure stripping in a dense cluster. If confirmed, it would be the most distant jellyfish galaxy ever found, offering rare clues into galaxy evolution during the universe’s peak star-forming era. Though more data is needed to confirm its classification, this discovery highlights how cluster environments shaped galaxies even in the early cosmos.

A new computer-modeling study reveals that dust devils on Mars—swirling columns of dust and air—may become electrically charged enough to spark lightning-like discharges. Led by researcher Varun Sheel, the study simulates how dry Martian conditions and frictional collisions between dust grains can generate strong electric fields inside these vortices. These charged whirlwinds pose potential risks to Mars rovers, as electrified dust may cling to solar panels, wheels, and antennas, reducing power and disrupting communications. NASA’s Perseverance rover may have already detected a small electrical discharge during a dust devil encounter. The findings highlight the need for robust, dust-resistant designs in future Mars surface missions.

NASA’s Perseverance rover is grinding into a strange Martian rock called Kenmore to study its inner makeup and potential for preserving signs of ancient life. The rock yielded clay and feldspar and, for the first time, manganese hydroxide, all key indicators of water-related processes and possible habitability on early Mars.

A team of astronomers using the Australia Telescope Compact Array (ATCA) discovered five young stars in the Chamaeleon cloud complex. One is a probable tight binary system. These findings enhance our understanding of early stellar evolution and the structure of southern star-forming regions.
