A black hole has a gravitational pull so intense that nothing, not even light, can escape it! Using data from the Chandra X-Ray Observatory (@nasachandraxray), astronomers discovered evidence for thousands of black holes located near the center of our Milky Way galaxy.
Pictured here is a black hole bounty consisting 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.
While a black hole by itself is invisible, when locked in close orbit with a star, high-energy light is produced and can be detected by scientific instruments so that astronomers can learn more about the properties of the black hole.
