The center of the Milky Way galaxy has tens of thousands of black holes.
According to a new study, there are tens of thousands of black holes at the center of the Milky Way galaxy.
Black holes are impossible to detect on their own because light can't escape from them. But when paired with a star, they interact in a way that allows scientists to find them using X-rays.
The study posits that the center of the Milky Way contains hundreds of black holes paired with stars and 10,000 isolated black holes.
