Scientists find an exotic black hole deemed a ‘needle in a haystack’

Astronomers have spotted in a galaxy adjacent to our Milky Way what they are calling a cosmic “needle in a haystack” – a black hole that not only is classified as dormant but appears to have been born without the explosion of a dying star.

Researchers said on Monday this one differs from all other known black holes in that it is “X-ray quiet” – not emitting powerful X-ray radiation indicative of gobbling up nearby material with its strong gravitational pull – and that it was not born in a stellar blast called a supernova.
