Astronomers detect water in interstellar comet 3I/ATLAS

For millions of years, a frozen fragment of ice and dust wandered alone between the stars, like a sealed bottle drifting in a cosmic ocean. Earlier this year, that “message in a bottle” entered our solar system. Astronomers named it 3I/ATLAS, only the third interstellar comet ever discovered. When scientists at Auburn University turned NASA’s […] The post Astronomers detect water in interstellar comet 3I/ATLAS appeared first on Knowridge Science…

Astronomers Discover Water Activity in Interstellar Object 3I/ATLAS

Astronomers have detected hydroxyl (OH) gas, a chemical indicator of water, from the interstellar object 3I/ATLAS using an ultraviolet/optical telescope on NASA’s Neil Gehrels Swift Observatory. Stacked images of the interstellar comet 3I/ATLAS obtained with NASA’s Neil Gehrels Swift Observatory: the first was captured on July 31 and August 1, 2025 (visit 1, upper half), [...] The post Astronomers Discover Water Activity in Interstellar Object 3…
