Discovery of an Ancient Celestial City Undergoing Rapid Growth: A Young Protocluster of Active Star-Forming Galaxies   September 21, 2012 A team of astronomers has discovered an ancient protocluster of galaxies in the midst of a vigorous process of formation. It is the densest and most active protocluster ever identified at so great a distance, 11 billion light years away from Earth. This is a region where the progenitors of present-day clusters of elliptical galaxies were just forming and undergoing rapid growth. The swift construction of this young protocluster helps us to understand the early growth of clusters and the effects of a dense environment on the formation and evolution of galaxies.
