Astronomers have discovered one of the rarest black hole events ever observed, revealing a massive “wandering” black hole far from the center of its home galaxy. The black hole’s powerful gravity tears the star apart, creating a brilliant burst of light that can briefly reveal an otherwise invisible black hole. The discovery points to the existence of a wandering black hole with a mass about one million times greater than that of the sun. The discovery is especially important because it demonstrates that wandering black holes can be found using ground-based optical telescopes. Every new tidal disruption event provides another piece of the puzzle, helping astronomers uncover the hidden history of the universe.
