Q&A: Milky Way Galaxy
How do we know there's a supermassive black hole in the center of the Milky Way?
The Milky Way galaxy's supermassive black hole, also known as Sagittarius A* (Sgr A*), is located in the center of this image (right). Chandra's observations have shown that flares from the black hole are very common. The cause of these flares is not understood, but they are thought to occur near the event horizon, or point of no return, around the black hole.
