Animation showing the locations and distances to some of our galaxy’s black holes

This artist’s animation, done with Space Engine, shows the locations and distances (in light-years [ly]) to some of our galaxy’s stellar black holes: Gaia BH3, a black hole now found to be the most massive stellar black hole ever identified; Cygnus X-1, the next most massive stellar black hole; and Gaia BH1, the closest black hole to Earth. At the centre of our galaxy, lurks Sagittarius A*, a supermassive black hole. 

Note that, due to a projection effect, Gaia BH3 looks closer to the Sun than Gaia BH1, but in reality the former is further away. It’s the second-closest black hole to Earth identified to date.
