Scientists find 2 stars thriving on the brink of a giant black hole

Just on the outskirts of a supermassive black hole roughly 4 million times more massive than the sun, a pair of stars locked in a dance is thriving. 

Astronomers discovered the duo orbiting Sagittarius A*, the Milky Way galaxy's central supermassive black hole, using the European Southern Observatory's Very Large Telescope in Chile. The binary system, the first ever found in the vicinity of an enormous black hole, is dubbed D9.

Black holes are some of the most inscrutable phenomena in space.
