• A group of Indian astronomers have discovered a massive supercluster of galaxies, and have named it Saraswati.

• The supercluster is about 4 billion light years away and spreads about 600 million light years across.

• This makes it one of the largest superclusters to be discovered and also the furthest.

• The first supercluster of galaxies, the Shapley Supercluster, was discovered in 1989, and the second, the Sloan Great Wall in 2003.

• The Milky Way galaxy is part of the Laniakea Supercluster, which was discovered in 2014.

• A galaxy cluster, or cluster of galaxies, is a structure that consists of anywhere from hundreds to thousands of galaxies that are bound together by gravity.

• A supercluster is a large group of smaller galaxy clusters or galaxy groups, which is among the largest-known structures.

• They are the largest known gravitationally bound structures in the universe.
