The Perseus–Pisces Supercluster (SCl 40) 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 (the other being the Laniakea Supercluster) in the nearby universe (within 300 million light-years). 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.[1]

Clusters

The main clusters of the Perseus–Pisces Supercluster are Abell 262, Abell 347, and Abell 426.
