TL;DR

ALMA observations show the interstellar comet 3I/ATLAS is unusually rich in methanol, released from both the nucleus and icy grains in the coma. The methanol-to-hydrogen cyanide ratio is higher than in Solar System comets, suggesting 3I/ATLAS formed under colder or chemically different conditions in another planetary system, providing a chemical fingerprint from a different star.
