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. This superclaster is also a part of the Perseus–Pegasus Filament which stretches for roughly a billion light years and is currently the largest known structure in the Universe.
