This image shows the galaxy density in the COSMOS field, with colours representing the redshift of the galaxies (ranging from redshift of 0.2 (depicted in blue) to 1 (depicted in red). The X-ray contours (in pink) show the extended X-ray emission as observed by XMM-Newton.

The Cosmic Evolution Survey (COSMOS) is an astronomical survey designed to probe the formation and evolution of galaxies as a function of cosmic time (redshift) and large scale structure environment. The survey covers a 2 square degree equatorial field with imaging by most of the major space-based telescopes, including Hubble and XMM-Newton, and a number of ground-based telescopes.
