Supermasssive Black Hole One or More

Scientists have just discovered a distant galaxy with not one but three supermassive black holes at its core.

The new finding suggests that tight-knit groups of these giant black holesare far more common than previously thought, and it potentially reveals a new way to easily detect them, researchers say. Supermassive black holes millions to billions of times the mass of the sun are thought to lurk at the hearts of virtually every large galaxy in the universe.

Most galaxies have just one supermassive black hole at their center. However, galaxies evolve through merging, and merged galaxies can sometimes possess multiple supermassive black holes.
