A team of Indian astronomers have identified previously unknown, extremely large supercluster of galaxies located in the direction of constellation Pisces. 

• It was discovered by astronomers from Inter University Centre for Astronomy and Astrophysics (IUCAA) and Indian Institute of Science Education and Research (IISER), both in Pune, Maharashtra.
• A supercluster is a chain of galaxies and galaxy clusters. It bound by gravity consisting of tens of thousands of galaxies.
• It is 4 billion light years away from Earth and may contain the mass equivalent of over 20 million billion suns.
• It has 43 galaxies that may contain thousands of suns, besides having billions of stars, planets, other bodies, gases and dark matter.

It is estimated to be stretched over 650 million light years in distance. The discovery of Saraswati supercluster will help astronomers in understanding galaxy formation and evolution, effect of superclusters on environment of the galaxies.
