Webb Spots Methane on Interstellar Comet

The James Webb Space Telescope just uncovered a cosmic oddball: comet 3-I/ATLAS, an interstellar visitor spitting out methane—something never seen before on a comet from another star system. Loaded with more carbon dioxide than most solar-system comets, it hints at a wildly different birthplace, likely far beyond our cosmic neighborhood. Webb’s infrared eyes revealed methane hiding deep inside, only released as the sun warmed its icy layers, and tracked how gas production dropped off as the comet cooled—water vanishing first. This comet’s weird chemistry and behavior paint a new picture of alien comet formation, proving Webb’s power to decode the invisible gases that tell cosmic stories.
