Mapping the universe: Scientists create the largest EVER chart of active supermassive black holes - featuring over one million voids

Daily Mail  

They're probably the most feared objects in the universe – huge concentrations of tightly-packed matter that can gobble up entire planets. The new map specifically shows 'quasars' – supermassive black holes that are actively feeding on material and emit electromagnetic radiation, becoming incredibly bright and luminous. An infographic explaining the creation of a new map of around 1.3 million quasars from across the visible universe Quasars are supermassive black holes that are actively feeding on material and emit electromagnetic radiation, becoming incredibly bright and luminous What are quasars? Quasars are supermassive black holes that are actively feeding on material and emit electromagnetic radiation, becoming incredibly bright and luminous. The new map logs the location of about 1.3 million quasars in space and time, the furthest of which shone bright when the universe was only 1.5 billion years old The European Space Agency's Gaia space telescope is around 930,000 miles away from Earth Most, if not all, galaxies possess monstrous black holes at their cores, including our own Milky Way galaxy.
