View Full Version : Swarm of Black Holes in the Milky Way

SUMMARY: Astronomers have used the Chandra X-Ray Observatory to find black holes orbiting closely around the supermassive black hole at the heart of our Milky Way galaxy. These relatively small, stellar-mass black holes probably migrated towards the middle of the Milky Way over the course of several billion years. Researchers had been predicting that black holes would move inward through a process called "dynamical friction", where they swap positions with lower mass stars, pushing them to the outskirts of the galaxy. The team found several candidates within 3 light-years of the supermassive black hole, and calculate that there could be as many as 20,000.
