Astronomers have measured a flicker of X-ray radiation coming from the supermassive black hole at the heart of the Andromeda Galaxy. Their observations were made with the Chandra X-ray Observatory, collated from 15 years of data, and highlighted two powerful flares in 2006 and 2013. These flashes matched a burst of neutrinos detected by the IceCube Neutrino Observatory, giving new insights into conditions around the supermassive black hole.
