In recent times, the Shapley Supercluster was rediscovered, in a survey of galaxies of galaxies at the University of Cambridge in England. In this paper, the supercluster was named after Shapley, in recognition of his pioneering survey of galaxies in which this concentration of galaxies was first seen. Around the same time, others had noticed a remarkable concentration of clusters in the Abell catalogue of galaxy clusters: they had named it the "Alpha concentration".
