Astronomers have identified a supermassive black hole that absorbs the equivalent of a Sun per day. The black hole is at the heart of the most luminous quasar ever observed, according to a study published in the journal Nature.
The light of J0529-4351, as it was named, had in fact been detected in the 1980s, recalls the study published Monday. The existence of such a massive and luminous object in the early Universe “is difficult to explain,” notes the study.
