NASA’s Webb Finds Clues to Ancient, Distant Origin of Comet 3I/ATLAS - NASA Science

NASA's Webb detected interstellar comet 3I/ATLAS with deuterium 30 times higher than solar comets and minimal carbon-13, suggesting formation 10-12 billion years ago. The isotope composition implies prebiotic chemistry conditions may be widespread in the galaxy.
