JWST Detects Ancient Ice Composition in Interstellar Comet 3I/ATLAS

NASA's James Webb Space Telescope has observed an unusual ice composition in interstellar comet 3I/ATLAS. The water ice signature suggests the comet formed in an extremely cold, low-metallicity protostellar cloud 10 to 12 billion years ago, potentially making it over twice the age of our Sun. This discovery offers significant insights into the conditions of the early universe and the formation of celestial objects beyond our solar system.
