Perseus-Pisces Supercluster
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 Local 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][2][3]

gollark: It also helps with sequencing them, you see, apioentity.
gollark: Um.
gollark: hahahahanoI Mean, technically yes, but one very big line.
gollark: Lyricly = utter eigenvalue.
gollark: Æ.
