Star in closest orbit ever seen around black hole (STA BREAKING NEWS and ARCHIVES)

by Theresa @, Thursday, March 16, 2017, 00:36

Astronomers have found evidence of a star that whips around a likely black hole twice an hour. This could be the tightest orbital dance ever seen by a black hole and a companion star in our own Milky Way galaxy.

This discovery was made using two of NASA's space-based telescopes, the Chandra X-ray Observatory and NuSTAR, and the Australia Telescope Compact Array located in New South Wales, Australia.

The stellar couple—known as a binary—is located in the globular cluster 47 Tucanae, a dense cluster of stars in our galaxy about 14,800 light years away from Earth.
