In News:

Indian scientists have discovered an extremely large supercluster of galaxies, which is as big as 20 million billion suns. Pune-based Inter University Centre for Astronomy and Astrophysics, IUCAA team of astronomers has named it Saraswati.

IUCAA said today, this is one of the largest known structures in the neighborhood of the universe, 4,000 million light-years away from Earth and roughly more than 10 billion years old. Its mass extends over the scale of 600 million light years.

Scientists of this institute were also involved in last year’s path-breaking discovery of gravitational waves.

The findings have been published in the latest issue of The Astrophysical Journal, the premier research journal of the American Astronomical Society.

About Supercluster

  • Superclusters are the largest coherent structures in the cosmic web. They are a chain of galaxies and galaxy clusters, bound by gravity, often stretching to several hundred times the size of clusters of galaxies.
  • Newly-discovered “Saraswati supercluster” extends over a scale of 600 million light-years and may contain the mass equivalent of over 20 million billion suns.
  • A cluster could roughly have galaxies ranging from 1000 to 10,000. A supercluster could have clusters ranging from 40 to 43.
  • Our Milky Way is part of the Local Group galaxy cluster (that contains more than 54 galaxies), which in turn is part of the Laniakea Supercluster.


The Inter-University Centre for Astronomy and Astrophysics is an autonomous institution set up by the University Grants Commission to promote nucleation and growth of active groups in astronomy and astrophysics in Indian universities.
