Caption: An artist's illustration on the left shows a typical massive galaxy from when the Universe was about a quarter of its current age. This galaxy contains an active galactic nucleus (AGN), or quasar, which is a luminous object powered by a central, supermassive black hole. The image on the right shows a Chandra image (low-energy X-rays in orange; high-energy X-rays in blue) that has been specially processed to detect incredibly faint X-ray sources. By combining Chandra and Spitzer observations of the same field of view, a new census of AGNs in galaxies in this early epoch was obtained.

Scale: Right panel is 25 arcsec across.
