Astronomers Discovered Thousands of Black Holes at the Center of Milky Way

The data was provided by NASA’s Chandra X-ray Observatory. “This black hole bounty consists of stellar-mass black holes” which are estimated to be five to 30 times the mass of our Sun. These new black holes were discovered within three light years of the supermassive black hole at our Galaxy’s center, called Sagittarius A*.
