Hubble Images Reveal Comet C/2025 K1 Breaking Apart Leaving Solar System

NASA and ESA's Hubble Space Telescope observed comet C/2025 K1 (ATLAS) breaking into at least four fragments over three days in November 2025 as it exited the solar system. This rare event offers valuable data on comet disintegration processes and unusual cometary composition, including a lack of carbon gases and a larger size. Scientists are now analyzing these findings to better understand comet physics and the early solar system's conditions.
