Multiple images of a distant quasar are visible in this undated combined view from NASA's Chandra X-ray Observatory and the Hubble Space Telescope. For the first time, scientists have measured the spin of a distant supermassive black hole and found that its rate of rotation is about 3.5 trillion mph -- roughly half the speed of light. The finding provides insights into how the black hole and its host galaxy formed.
