Chandra X-ray & Hubble Optical/Infrared Images
The growth of the biggest black holes in the Universe is outrunning the rate of formation of stars in the galaxies they inhabit, according to two studies using data from Chandra and other telescopes. These images show data from the Chandra Deep Field-South in optical and infrared light from the Hubble, and X-ray light from Chandra.

Each Chandra source, shown above, is produced by hot gas falling towards a supermassive black hole in the center of the host galaxy, as depicted in this artist's illustration.
