Black holes are sitter gatherers rather than hunters, patiently waiting for hapless stars to pass by. When the star is close enough, the black hole’s huge gravity will tear it apart and swallow it, releasing intense radiation at the same time. This phenomenon is known as a black hole tidal disruption event. Astronomers are using the Hubble Space Telescope to watch a star being swallowed by a black hole. Dubbed AT2022dsb, the event devoured the star nearly 300 million light-years from the center of galaxy ESO 583-G004. It was captured by the ASAS-SN (All-Sky Automated Survey for Supernovae) automated system on March 1, 2022, astronomers observed the black hole twisting its captured star into the shape of a doughnut.
