Astronomers Observe First-Ever Awakening of Supermassive Black Hole
Astronomers have observed a supermassive black hole in the distant galaxy SDSS1335+0728 transition from an inactive to an active state, emitting various types of radiation over four years. This unprecedented event, possibly due to a tidal disruption event or a new phenomenon, provides new insights into the processes that fuel active galactic nuclei and the evolution of supermassive black holes.
