The Pisces-Cetus Supercluster Complex is a complex of galaxy superclusters or galaxy filament that includes the Local Supercluster (Virgo Supercluster, the supercluster in which the Local group, the galactic cluster that includes the Milky Way Galaxy, is located).[1]

Discovery

Astronomer R. Brent Tully of the University of Hawaii’s Institute of Astronomy identified the Complex in 1987. [2]

Extent

The Pisces-Cetus Supercluster Complex is estimated to be about 1.0 billion light years long and 150 million light years wide. It is one of the largest structures identified so far in the universe,[3] but is exceeded by the 1.37 billion-light-year long Sloan Great Wall.

The complex comprises about 60 clusters and is estimated to have a total mass of 1018 M☉[4]
