NASA's Webb detects methane and strange chemistry on interstellar comet 3I/ATLAS
NASA's James Webb Space Telescope has detected methane and high levels of carbon dioxide on the interstellar comet 3I/ATLAS. These chemical signatures suggest the comet formed in an environment significantly different from our own solar system.
Why it matters
Understanding the chemical composition of interstellar objects helps scientists learn more about the formation of planetary systems beyond our own.
NASA's James Webb Space Telescope has captured the first mid-infrared chemical fingerprint of an interstellar object, providing new insights into the composition of comet 3I/ATLAS as it traveled away from the Sun. The findings were recently published in The Astrophysical Journal Letters .
