Astronomers have observed the largest and most distant flare ever detected from a supermassive black hole, nicknamed “Superman,” originating 10 billion light-years away.

At its peak, the flare shone with the brightness of 10 trillion suns.

The flare came from an active galactic nucleus (AGN), where gas and dust spiraling into a supermassive black hole become superheated, emitting intense radiation.

Researchers believe the black hole likely consumed a massive star, producing this unprecedented flare, CNN has reported.

Such extreme flaring is extraordinarily rare, occurring in roughly one in a million AGN, according to the study published in Nature Astronomy.
