Astronomers have discovered evidence for thousands of black holes located near the center of our Milky Way galaxy using data from NASA’s Chandra X-ray Observatory.
This black hole bounty consists of stellar-mass black holes, which typically weigh between five to 30 times the mass of our Sun. These newly identified black holes were found within three light-years — a relatively short distance on cosmic scales — of the supermassive black hole at our Galaxy’s center known as Sagittarius A* (Sgr A*).
This recent analysis using Chandra data is the first observational evidence for such a black hole bounty.
Some of these X-ray binaries appear as point-like sources in the Chandra image.
