James Webb telescope finds water around a comet in the main asteroid belt

The James Webb Space Telescope just made its second breakthrough observation in as many weeks. Researchers have used the observatory's near-infrared camera to detect the first known instance of water vapor around a comet in the main asteroid belt, also known as a main belt comet. Scientists had thought comets could preserve water ice so relatively close to the Sun, but didn't have firm evidence until now. They generally expected comets to sit in the Kuiper Belt or Oort Cloud, both of which are far enough away from the Sun that ice could last.
