INDIAN SCIENTISTS DISCOVER 'SARASWATI' -- A SUPERCLUSTER OF GALAXIES

New Delhi -- 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, the premier research journal of
the American Astronomical Society.
"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,
consisting of tens of thousands of galaxies," the IUCAA
said in a statement.
Sankhyayan said this "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.
