NGC 3115 in 60 Seconds

View/Listen
Narrator (April Hobart, CXC): This is NGC 3115, a galaxy located about 32 million light years from Earth. This composite image contains X-rays from Chandra as well as optical data from the Very Large Telescope. Using the new Chandra image, astronomers have imaged the flow of hot gas as it falls toward the supermassive black hole in the center of NGC 3115. This is the first time such a flow has been clearly imaged in any black hole. The Chandra data also provide evidence that the black hole in NGC 3115 has a mass of about two billion times that of the Sun. This would make NGC 3115 the host of the nearest billion-solar-mass black hole to Earth.
