An Interstellar Visitor's Chemical Fingerprint Is Unlike Anything in Our Solar System
Webb's MIRI instrument detected methane, carbon dioxide, and water vapor on comet 3I/ATLAS — the first mid-infrared chemical fingerprint ever taken of an interstellar object. The methane-to-water ratio has no good analog among solar system comets, hinting at a formation environment radically different from our own.
