The James Webb Space Telescope just checked out comet 3I/ATLAS, and it’s blowing scientists’ minds. Not only is this icy visitor from another star system super old—like, 7 billion years old—but it’s got the highest carbon dioxide-to-water ratio ever seen in a comet. That could mean it formed in some wild, radiation-packed corner of the galaxy. Basically, this cosmic traveler is rewriting what we know about how comets (and maybe even planets) are born! #Science #JamesWebb #SpaceScience
