Perseus-Pisces Supercluster
The Perseus-Pisces Supercluster is one of the largest known structures in the universe. Even at a distance of 250 million light-years, this chain of galaxy clusters extends more than 40° across the northern winter sky. The Perseus-Pisces Supercluster is one of two dominant concentrations of galaxies in the nearby universe. This supercluster also borders a prominent void, the Taurus Void, and is part of the Perseus–Pegasus Filament which stretches for roughly a billion light years.Clusters
The main clusters of the Perseus–Pisces Supercluster are Abell 262, Abell 347, and Abell 426.
