SPACE reports, “In a landmark observation by a team of international researchers, NASA’s Juno spacecraft has, for the first time, clearly detected the auroras of Jupiter’s moon Callisto. This discovery completes the set of auroral signatures we have from all four Galilean moons: Io, Europa, Ganymede and Callisto.”

James Webb Space Telescope Discovers Water Vapor in Distant Planet’s Atmosphere
SPACE reports, “NASA’s James Webb Space Telescope has found water vapor swirling in the air of a distant, boiling-hot alien planet, a new study reports. That exotic world is TOI-421 b, a boiling-hot “sub-Neptune” orbiting a star about 244 light-years from Earth whose atmosphere JWST recently probed in detail.”

Webb Telescope Spots Possible Signature of Life on Distant Planet
The Washington Post reports, “A distant planet’s atmosphere shows signs of molecules that on Earth are associated only with biological activity, a possible signal of life on what is suspected to be a watery world, according to a report published Wednesday that analyzed observations by NASA’s James Webb Space Telescope. The peer-reviewed report in the Astrophysical Journal Letters presents more questions than answers, acknowledges numerous uncertainties and does not declare the discovery of life beyond Earth, something never conclusively detected. But the authors do claim to have found the best evidence to date of a possible “biosignature” on a planet far from our solar system.”

Perseverance Rover Finds Mysterious Boulder “Never Observed Before” on Mars
CBS News reports, “While exploring a crater on Mars that may give scientists insights into life that potentially once existed there, NASA said its Perseverance rover made an unprecedented discovery. The rover, which landed on the Red Planet in 2021 specifically to probe the ancient Jezero crater, found a mysterious light-toned boulder earlier this month that was the first of its kind seen on Martian land.”
