Astronomers have characterised the most luminous quasar observed to date, which is powered by the fastest-growing black hole. This black hole is growing in mass by the equivalent of one Sun per day. The matter being pulled in toward this black hole forms a disc that measures seven light-years in diameter -- about 15 000 times the distance from the Sun to the orbit of Neptune.
