The “galactic underworld” of black holes has been discovered in our Milky Way Galaxy

Over the roughly 13.6 billion year history of our Milky Way Galaxy, billions of stars have formed, grown, and eventually died in spectacular supernova explosions. So, where are all their corpses hiding?

In new research published on August 25 at Monthly Notices of the Royal Astronomical Society, astronomers set out to dig up those long-lost stellar bodies (so to speak). Using a computer simulation, the team modeled the initial positions of millions of stars at the beginning Galaxy (long before it developed its iconic spiral arms), then hit a cosmic fast-forward button to show where the shrunken remains of these stars might have ended up after going supernova.
