Astronomers have used the death of a star to uncover details about a hidden intermediate-mass black hole.
A single high-energy neutrino may shed light on a star being swallowed by a supermassive black hole some 690 million light-years away.
Astronomers can't agree on what kind of strange stellar death created a brilliant source dubbed "the Cow."
Every now and then, the Milky Way’s central, supermassive black hole tears apart a star and flings away some of its innards. Now astronomers think they know how to spot these cosmic spitballs.
