Pisces Supercluster Complex Whale

Pisces supercluster complex Whale is a complex of superclusters of galaxies and galactic filaments which includes the Local Supercluster where our Milky Way ^Discovery

The astronomer R. Brent Tully of the Astronomical Institute of Honolulu in Hawaii identifies the complex in 1987 .

Scope

Pisces supercluster complex Whale has an estimated length of a billion light-years and estimated width of 150 million light years. It is the largest structure identified from the universe to date , behind the Sloan Great Wall which extends over 1.37 billion light years.

The complex contains about 60 clusters of galaxies and is estimated to have a total mass of 10 ¹⁸solar masses . According to the discoverer, the complex consists of 5 parts:

1. The Supercluster Fish Whale
2. The Pegasus-Perseus chain
3. The Pegasus-Pisces chain
4. The region of Sculptor
5. The Hydra Supercluster Virgo-female-Centaurus , a superset of our Local Supercluster (Virgo supercluster) .

As a reminder, with a mass of 10 ¹⁵solar masses , our Local Supercluster represents only 0.1% the total mass of the complex.
