The universe we live in is the most, most mysterious thing ever and it is so enormous, so humongous in size that it is beyond our thinking power. To add to our bewilderment, a group of Indian astronomers have discovered a new ‘supercluster’ of galaxies, and named it Saraswati.
How bright is the Sun? So how bright would be 200 million such suns? Luminous, right! That would be one galaxy. And the universe is made of infinitely unknown and unimaginable number of clusters of galaxies, yes clusters. Then there are larger clusters with even more galaxies which are called superclusters. A group of astronomers led by Joydeep Bagchi of Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune, have discovered a supercluster of 43 clusters and over 10,000 galaxies!
This is one of the largest known celestial structures in the known universe which is located at 4000 million light years away from us and the supercluster itself stretches across an are of 600 million light years. That is IMMENSE size! This galaxy was named ‘Saraswati’ by the group of Indian astronomers and it is estimated to have a mass of twenty thousand trillion suns which might be made of billions of stars, planets, asteroids, gases and dark matters. Saraswati is estimated to have originated some 10 billion years ago and all these numbers are so large, it literally makes our minds stop working, it is way, way, way beyond our brain’s capacity.
Talking about ourselves for a bit, since it is all oh-so-veryyy-exciting, our solar system is the proud member of our Milky Way and so far we have discovered over 500 solar systems but it is estimated that Milky Way might be made of up to 100 billion solar systems, or more. And our Milky Way is the teeny-tiny (yes, Milky way is teeny-tiny) member of Laniakea Supercluster.
As per estimates, there are 10 million superclusters in the observable universe. So just in case if you start feeling that you are too important, well, even our Milky Way galaxy is merely dust when compared to the entire universe. Talking from the perspective of universe, we don’t even exist, at all, so kindly peace out. And just sink in the deepest mysteries and the absolute beauty of this utterly magnificent universe we reside in.
