Astronomers Discover A Supercluster Of Galaxies

Saraswati galaxy

Marking a noteworthy discovery, a team Indian astronomers has uncovered a previously unknown "supercluster" of galaxies, naming it "Saraswati". The supercluster is about 4 billion light years away and spreads over a "great wall" about 600 million light years across.

Mr Sankhyayan reported this "newly discovered supercluster- Saraswati" extends to approximately 600 million light years and is an estimated to have contained mass equivalent to around 20 million billion suns. It comprises a total mass of more than 20 million billion suns.

"We were very surprised to spot this giant wall-like supercluster of galaxies, visible in a large spectroscopic survey of distant galaxies, known as the Sloan Digital Sky Survey", said Joydeep Bagchi from IUCAA, the lead author of the paper.

This novel discovery is being published in the latest issue of The Astrophysical Journal, the premier research journal of the American Astronomical Society. As the Saraswati supercluster was formed relatively early, it could give us a unique opportunity to characterise the early universe and probe the tiny fluctuations that expanded after the big bang to form the largest structures.

As Saraswati is so far away and its light takes time to reach us, studying it allows us to look back in time to when the universe was only about 10 billion years old.

Galaxies are gravitationally bound and are a part of filaments -massive thread-like formations- that form the boundaries between large cosmic voids in the universe.

The long-popular "Cold dark matter" model of the evolution of the Universe predicts that small structures like galaxies form first, which congregate into larger structures.

Dwelling deeper, the team explained that their work will help in shedding light over the perplexing question of the formation of extremely large-scale, prominent matter-density enhancements in the past coinciding with the time of dominant structure formations by the mysterious Dark Energy. More commonly known as the Goddess of knowledge in Hindu mythology, Saraswati is also the celestial goddess believed to be the keeper of the celestial rivers. The milky way galaxy, where our planet Earth lives, is the part Laniakea cluster. The Saraswati supercluster was formed in an era when it is thought that dark energy was just starting to accelerate the universe's expansion, making it a product of the delicate balance between dark energy and dark matter. The Saraswati supercluster could challenge this premise, because it was formed so early and building such a big structure far back might have been hard.
