NASA’s MAVEN Illuminates New Understanding of Auroras at Mars

NASA MAVEN (Mars Atmosphere and Volatile Evolution) mission scientists have uncovered a key puzzle piece in understanding certain types of auroras on Mars, finding that they form in a similar way to Earth-based auroras. Results published Thursday in Nature Communications show the same mechanism that circulates and catapults charged particles into E

NASA’s Webb Finds Clues to Ancient, Distant Origin of Comet 3I/ATLAS

As interstellar comet 3I/ATLAS began moving away from the Sun in December 2025, astronomers took the opportunity to turn NASA’s powerful James Webb Space Telescope in its direction and capture detailed measurements of its chemical components. The comet was freshly warmed from its closest pass by the Sun, and its ancient ice had been converted […]

NASA’s Curiosity Finds Organic Molecules Never Seen Before on Mars

After years of lab work, the results are in: A rock that NASA’s Curiosity Mars rover drilled and analyzed in 2020 includes the most diverse collection of organic molecules ever found on the Red Planet. Of the 21 carbon-containing molecules identified in the sample, seven of them were detected for the first time on Mars. […]
