Galaxy 1068 located about 47 million light-years away in the constellation Cetus is shown in visible light and X-rays in this NASA composite image released on December 17, 2015. High-energy X-rays (magenta) captured by NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, are overlaid on visible-light images from both NASA's Hubble Space Telescope and the Sloan Digital Sky Survey. The X-ray light is coming from an active supermassive black hole, also known as a quasar, in the center of the galaxy. This supermassive black hole has been extensively studied due to its relatively close proximity to our galaxy. (Photo by Reuters/NASA/JPL-Caltech/Roma Tre Univ)
