While it's much smaller than the largest supermassive black holes detected, it's still a whopper considering how early in the history of the universe it appeared. An enormous black hole in the ...

In a galaxy 300 million light-years away from Earth, a once-quiet black hole has woken up. Astronomers became aware of this galaxy in the Virgo constellation when it abruptly began to light up in ...

A lthough we know that supermassive black holes (millions of times the mass of our sun) lurk at the center of most galaxies, their very nature makes them difficult to spot and study. In contrast ...
