Hungry black hole turning star into cosmic donut

Astronomers have discovered a monstrous black hole with an appetite and a sweet tooth. The black hole is tearing apart an unfortunate star, pulling it apart like taffy and whipping the “leftovers” into a stellar donut the size of the Solar System before feasting on this cosmic confectionery.

The All-Sky Automated Survey for Supernovae (ASAS-SN or “killer”) observed for the first time a violent event through a flash of high-energy radiation, known as a tidal disruption event (TDE). The feast is taking place at the center of a galaxy 300 million light-years away.
