Hello to all the beautiful ladies and gentleman of this amazing community #steemit!
Dear Steemians,

Wholehearted greetings to all of you! Hope you are doing awesome in your life. In today's post, we will discuss the third part in continuation to my previous post [here] of the series "Ultimate Guide To The Universe For Any Age". There will be another part also coming related to this topic with the prime focus to provide quality rich content and also to not to make this publication lengthy.

After understanding virtually most of the rudimentary things about our universe. In this publication, we will endeavor to discuss a recent revelation in the universe designated “Saraswati supercluster”. So, let me first tell you what all we are going to discuss in this post! I'll endeavor to cover what Saraswati supercluster is all about and what Stripe 82 region of SDSS is! Further, we will withal endeavor to discuss whether Saraswati supercluster is the only one supercluster that the Indian scientists and researchers have discovered in terms of galaxy and supercluster? Apart from that, I will additionally endeavor to keep on explicating in between the discussion in this publication about the various facts of our galaxy. For example; which is the most astronomically immense star in the universe so far, etc. This will be fascinating you all and will going to be a profoundly intriguing discussion. So, let's commence!

We just discussed in my previous post [here] that there might be around 1 trillion stars and around 400 billion stars might be subsisting in Andromeda galaxy and Milkyway galaxy respectively. Now, let's discuss the only yellow dwarf in our solar system “Sun”. It is an average size star and after 5 billion years it will commence expanding resulting in the ravagement of our entire solar system including Earth. 5 billion years is genuinely very far. So, don't be apprehensive about it.

Coming to the next sub-topic of discussion, in our known entire universe UY Scuti is the most immensely colossal of all the stars that have been discovered till now. This designation of being the most sizably voluminous of all the stars keep on transmuting from time to time as the researches and revelations keep on proceeding and later it might transpire that some other incipiently discovered star could take the designation of being the most astronomically immense of all the stars in the known universe which might again be taken by some other stars in near future, so on and so far. So, ascertain to be updated with the latest known most immensely colossal star of the universe.

Earlier to UY Scuti, VY Canis Majoris was considered to be the most immensely colossal of all the star of that time and earlier to the VY Canis Majoris there were other stars as well which was considered to be the most immensely colossal star of that time. So, till now we have accumulated some conception about what precisely are galaxies considering my anterior post as well [here]. From here, we will now move further to the Galaxy group - what precisely they are and how sizably voluminous can they be?

Till my anterior publication [here] and the above paragraphs, we have discussed the two galaxies namely Milkyway galaxy and Andromeda galaxy what they are and where they are located. Now, just imagine, just like these two galaxies if there are around 20 more galaxies comes into subsistence. This will together form the galaxy group and the galaxy group having around several hundred galaxies will be called a cluster. So, the cluster is that system in the space where several hundreds of galaxies subsist. Now, again a group of clusters forms the supercluster and is regarded as the most sizably voluminous bodies in the known universe and no other more sizably voluminous astronomical bodies are subsisting in the known universe except the supercluster.

Generally, in a supercluster, there can be two or four clusters subsisting. But now will endeavor to understand why Saraswati supercluster is so special! So, I have just expounded in the above paragraph that at supercluster is the known most astronomically immense coherence structure of all and you will not find any other more astronomically immense structure than supercluster in the known entire universe.

In Saraswati supercluster which has been discovered recently is having 42 clusters in it which make it special regardless of other superclusters discovered so far. So, Saraswati supercluster is the most immensely colossal of all the supercluster so far which has been discovered by a team of Indian scientists from the Inter University Centre for Astronomy and Astrophysics (Pune, India), Indian Institute of Science Edification and Research (Pune, India), NIT Jamshedpur (India) and Newman College (Pune, India). This team was led by Dr. Somak Raychaudhry, Director of Inter University Centre for Astronomy and Astrophysics, Pune, India.

So, where precisely is the Saraswati supercluster located in the universe? Afore knowing this, we should first endeavor to understand that since the year 2000 there is a process going on for mapping the universe digitally which is known as Sloan Digital Sky Survey (SDSS). So, what they are endeavoring to do in SDSS and what is it concerned with? Since the universe is so immensely colossal and we humans like maps to identify and locate various locations and object. So, in SDSS, they are rudimentary endeavoring to engender 3D-Map of the universe so as to process our understanding about the various astronomical bodies and their location, etc.

The central part of SDSS is Stripe 82. SDSS is playing a paramount role in mapping the entire universe digitally. In the center of this map there is a stripe known as Stripe 82 and in this Stripe 82 comes the Saraswati supercluster. Saraswati supercluster is 4000 million light years away from our Milkyway galaxy and lies in the Pisces constellation.
