Wholehearted greetings to all of you! Hope you all are doing awesome in your life. In today's publication, we will discuss the second 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 up on this topic with the prime focus to provide quality rich content and also to not to make this publication lengthy.
In this publication, first of all, we will endeavor to discuss what are galaxies and planets? What is a solar system? I will endeavor to discuss all the fundamental conceptions in brief aforegoing in depth about “Saraswati Supercluster” in my next upcoming publication. This will be going to be an inordinately fascinating topic to discuss! I conjecture this will be fascinating you all and will going to be a profoundly intriguing discussion. So let's commence!

The picture that you are optically discerning in the Image No- 2, is our solar system where our home planet is located. Here, you can optically discern the Sun and the other planets are orbiting. First in the sequence is the planet denominated Mercury. Then comes the Venus and you can visually perceive its orbit as well. Next comes the planet Earth where we all reside or live. We have prosperously done an abundance of developments in our planet Earth because of which it will be looking homogeneous to flickery in our vision which generally the astronomers relishes a lot optically canvassing this mesmerizing scenario and the conception of this comely vision of the flickering Earth can be felt visually examining the Image No- 3.

Then comes the planet Mars in the sequence to which we are orchestrating for colonization in the near future. Next, to Mars, you could be able to visually perceive the planet Jupiter which is the giant gas planet and is authentically prodigiously and sizably voluminous in size. Then comes the Saturn and adjacent to it in the sequence is Uranus of which you could be able to visually perceive its orbit as well in the Image No- 2. Determinately, comes the Neptune which is having the most sizably voluminous orbit of all in our own known solar system.

Now, if I ask you a question, where do you reside in the universe? You will be answering that we all are living on planet Earth. All right! If I ask you again, where is our planet Earth located? Then you will be answering it is located in our solar system. Again, if I ask you all, where is our solar system located? Then only some of you might answer that our solar system is located in the Milkyway galaxy. Now again, if I ask, where is Milkyway galaxy located? Then the question commences getting intricate. In this publication, we will be endeavoring to discuss and answer all such questions about where precisely we are located in this universe!

Visually perceive, first, let's commence with the Milkyway galaxy. So, what are galaxies? Here I will endeavor to congruously explicate what galaxies are precisely. I have already discussed in the above paragraphs that we live on planet Earth which is a small part of our solar system. Our solar system comes under the Milkyway galaxy. So, what a Galaxy is fundamentally? Look, in the entire solar system there are lots of galaxies and the Milkyway galaxy is a minutely diminutive galaxy as compared to the other galaxies in the universe. There are lots of other astronomically immense galaxies subsisting in the universe as well.

So, answering the question, a galaxy is rudimentally an amassment of various gases, dust and billions of stars along with their solar system. It is estimated that in our Milkyway galaxy, there could be around 200 to 400 billion stars subsisting like the Sun. Now, what rudimentally the Sun is? The Sun is a mundane star like others. So, sundry stars between 200 to 400 billion in numbers some of which are even more immensely colossal than the Sun and some are more diminutive in size than our Sun could be subsisting just in our Milkyway galaxy itself. It is inordinately fascinating to know and a galaxy stays in a particular location or coordinates due to the gravity.

In the center of the Milkyway galaxy, there is a supermassive black hole subsisting which is attracting and victualing up all the other astronomical bodies subsisting in our Milkyway galaxy. But it will take billions of year for the supermassive black hole to victual the entire Milkyway galaxy. Till then, we don't even know if our human race will be subsisting or not? So, we don't have to fear about that at present.
There is various type of galaxies found such as Spiral galaxy, Elliptical galaxy, and Irregular Galaxy. The Milkyway galaxy is a type of Spiral galaxy. More proximate to the Milkyway galaxy, there is another Galaxy located which is denominated as Andromeda Galaxy. Now, we don't even know precisely how many galaxies are subsisting in the entire universe! Coming back to the topic, Andromeda Galaxy is additionally known with other names as well such as Messier 31, M31, NGC 224 and is additionally a type of spiral galaxy.

The observation revealed by the Spitzer Space Telescope back in the year 2006 verbally expressed that the there might be twice or thrice times of the total number of stars in the Milkyway galaxy might be subsisting in the Andromeda Galaxy which can be either more diminutive or more sizably voluminous than the size of the Sun and there is additionally a theory verbally expressing that billion of year later, these two galaxies namely Milkyway galaxy and Andromeda Galaxy might be colliding with each other.
