Nearly 900 million light years away, a supermassive black hole has the munchies
at Syracuse University in New York presented the discovery on 12 January at a meeting of the American Astronomical Society in Seattle.
The first bite that astronomers spotted was in 2018 when the black hole – which has a mass 6 billion times that of the sun –and stayed bright for about 600 days. This happens anytime a star gets too close to a black hole, at which point it gets shredded by the powerful gravitational field, creating a stream of hot, bright stellar material that then falls into the black hole and dims again. That particular TDE was recorded, and once it rapidly died down astronomers thought that was the end of it.
