Indian scientist find one of the largest known structures in the nearby universe, name it Saraswati
In what could be one of the biggest discoveries in space science, a team of astronomers from the Inter University Centre for Astronomy & Astrophysics (IUCAA), and Indian Institute of Science Education and Research (IISER), both in Pune, India, and members of two other Indian universities, have identified a previously unknown, extremely large supercluster of galaxies located in the direction of constellation Pisces. This is one of the largest known structures in the nearby Universe and is at a distance of 4,000 million (400 crore) light-years away from us.
- This supercluster is a major concentration of galaxies and galaxy clusters, forming a wall-like structure
- his places it among the few largest and most massive superclusters known, comparable to the most massive `Shapley Concentration’ in the nearby universe
- In recent years, the discovery of the present-day Universe being dominated by “Dark Energy”, which behaves very differently from Gravitation, might play a role in the formation of these structures.
- This galactic concentration sheds light on the role of dark energy and cosmological initial conditions in supercluster formation, and tests the competing cosmological models.Read more at: https://phys.org/news/2017-07-massive-large-scale-universe.html#jCp
