Astronomers have spotted an apparent supermassive black hole snacking on a star 600 million light-years away, wandering through a galaxy with an even larger black hole at its core.

“The classic location where you expect massive black holes to be in a galaxy is in the center, like our Sag A* at the center of the Milky Way,” explained lead researcher Yuhan Yao of UC Berkeley.

Astronomers can’t see a black hole, but they can see the lensing effect and the gravitational pull on passing stars. The new study is based on recent observations using the Hubble Space ...
