NASA Telescope Reveals Interstellar Comet 3I/ATLAS Encased in Carbon Dioxide Fog

NASA's SPHEREx telescope has revealed that the interstellar comet 3I/ATLAS is wrapped in carbon dioxide fog and water ice, indicating it was well-processed before ejection from its parent system, likely originating from far away in the Milky Way's thick disk. This discovery provides insights into the composition of interstellar objects and demonstrates SPHEREx's advanced capabilities in sky mapping and chemical analysis.
