This false-colour image from NASA's Spitzer Space Telescope shows a distant galaxy (yellow) that houses a quasar, a super-massive black hole circled by a ring, or torus, of gas and dust. Spitzer's infrared eyes cut through the dust to find this hidden object, which appears to be a member of the long-sought population of missing quasars. The green and blue splotches are galaxies that do not hold quasars. In this image, infrared data from Spitzer is coloured both blue ( microns) and green (24 microns), and radio data from the Very Large Array telescope is coloured red. The quasar-bearing galaxy stands out in yellow because it emits both infrared and radio light.
