Shapley Attractor

Attractor in the Shapley supercluster

The Shapley attractor is a massive cluster of galaxies located in Shapley Supercluster, most well known for its high density and gravitational pull. Like the Great Attractor, it is obscured by the Milky Way's galactic plane, lying behind the Zone of Avoidance (ZOA), so that in visible light wavelengths, it is difficult to observe directly.
