Supermassive black holes are millions of times bigger than the sun and “feast” on their surroundings. But despite their size, the galactic giants can often evade detection. In a forthcoming paper in the Astrophysical Journal, researchers describe five different supermassive black holes. Astronomer George Lansbury, lead author on the study, discusses why the super-sized black holes are so difficult to find and what they can tell us about the evolution of the universe.
