Astronomers have used a mix of low-frequency telescopes, supercomputers, and algorithms to create an unlimited sky map of 25,000 supermassive black holes.

The map reveals 1000’s of twinkling dots that appear like stars, however are literally monumental black holes, every of which is positioned in a distinct, distant galaxy.

The researchers pinpointed the celestial objects by analyzing radio emissions emitted by matter that was ejected when it bought near the black holes.
