The Shapley Supercluster

Looking from Earth, the main clusters of the Centaurus supercluster (with yellow labels) lie directly in front of the Shapley supercluster.

Between the Centaurus and Shapley superclusters, at a distance of about 500 million light years, is another small supercluster (with green labels).

At a distance of 650 million light years is a massive concentration of major galaxy clusters (marked with blue labels) This is the Shapley supercluster first noticed by Harlow Shapley in 1930.
