Interstellar comet 3I/ATLAS is bursting with methanol

Interstellar comet 3I/ATLAS contains exceptionally high levels of methanol, suggesting it formed under conditions very different from those that shaped most comets in our solar system. ALMA also revealed that tiny icy grains around the comet are releasing methanol like miniature comets, giving astronomers an unusually detailed look at an object from another star system.
