The Milky Way’s supermassive black hole has a hot spot

Astronomers have spotted a bright ‘hot spot’ swirling around the supermassive black hole at the heart of our Milky Way galaxy, Sagittarius A* (Sgr A*). 

The team behind the discovery thinks that the ‘hot spot’ could be a bubble of hot gas orbiting Sgr A* as fast as 30% of the speed of light. The discovery could help astronomers and astrophysicists better understand the violent environment at the center of the Milky Way, and around Sgr A* in particular.
