Scientists spot a supermassive black hole that wanders through space

Astronomers have detected a highly unusual case of a black hole wandering through space.

Astronomers previously believed it was possible for supermassive black holes to be actively on the move, but it has been difficult to gather evidence for that theory -- until now. The supermassive black hole is located in the galaxy J0437+2456 230 million light-years away from Earth.
