A team of Indian astronomers has discovered an extremely large supercluster of galaxies — as big as 20 million billion suns — which they have named Saraswati, Pune-based Inter University Centre for Astronomy and Astrophysics (IUCAA) said today. This is one of the largest known structures in the neighbourhood of the universe, 4,000 million light-years away from Earth and roughly more than 10 billion years old, IUCAA said. Its mass extends over the scale of 600 million light years, it said.
Scientists of this institute were also involved in the path-breaking discovery of gravitational waves last year. The supercluster was discovered by Shishir Sankhyayan, a PhD student at the Indian Institute of Science Education and Research (IISER), Pune, Pratik Dabhade, IUCAA research fellow, Joe Jacob of the Newman College, Kerala, and Prakash Sarkar of the National Institute of Technology, Jamshedpur.
Their findings were published in the latest issue of The Astrophysical Journal, …
