Chandra Deep Field South

June 15, 2011

This sequence of images begins with a large optical image of the southern sky. The view zooms into the 4-million-second exposure of the Chandra Deep Field South, and then an optical and infrared image from the Hubble Space Telescope is overlaid. This provides evidence that growing black holes have been detected in 30% to 100% of the distant galaxies.
