This is a composite X-ray/submillimeter image of the Chandra Deep Field North. The Chandra Deep Field North lies in the constellation of Ursa Major, Green and red correspond to the Herschel SPIRE 250 and 350 micron images showing the sky crowded with submillimeter-bright, dusty galaxies. Blue shows the X-rays recorded by Chandra, most of which come from active galactic nuclei. SOURCE/ESA/Herschel/HerMES; NASA/CSX
Astronomers, using the European Space Agency’s (ESA) Herschel Space Observatory, have shown that the number of stars that form during the early lives of galaxies may be influenced by the massive black holes at their hearts. This helps explain the link between the size of the central bulges of galaxies and the mass of their central black holes.
