A new study revealed that astronomers, who have classified a incredibly luminous outburst detected by the All-Sky Automated Survey for Supernovae (ASAS-SN) last year as the brightest supernova ever found, were mistaken because the luminous outburst may actually be a supermassive black hole ripping an unfortunate star.
A NASA telescope has observed for the first time black holes eating stars and emitting flares of high-energy radiation.
A new x-ray reverberation mapping technique was used by astronomers to study tidal disruptions. Tidal disruption happens when a star falls into a black hole that then leads to its death. Stellar materials are caught into the spinning disc formed outside the black holes. This behavior can now be observed using the new x-ray technology.
