Hello friends, welcome back to our post. In this post, I am going to tell you about how the sun was formed. This post is very interesting and mind-blowing. Read this post in its entirety.
Introduction
The sun is what drives our solar system. Our sun
is the center of our sun. The 8 planets and other satellites, small planets,
asteroids, and all these things are moving around. This is all due to the
gravitational force of our sun. Our sun is many times larger than our earth and
contains a lot of matter. You must have wondered how such a sun was formed. We
are going to read about this in this post. Okay, okay!
1. Do you know where the sun came from?
Have you heard of a nebula? It is a collection of dust, gas, and small rocks that is larger than our sun. Scientists say that our sun and all other suns were born from this nebula. But there are millions and millions of nebulae in our space. Every second or every second, a sun is being born from this nebula. Not only that, scientists say that every second, every second, there is a sun or stars. The sun is the same as the stars.
It is from such nebulas that stars are formed. Our Sun is a star that was formed about 4.6 billion years ago. It has been about 4.6 billion years since our Sun was formed. When the tissues and gases in the nebula collide with each other at high speed and rotate, a large or small star with a powerful gravitational force is born.
2. So what is there in the nebula?
The nebula contains a large amount of dust, gases, small rocks and two very important substances, which are hydrogen and helium. Because you know this, our sun has a lot of hydrogen and helium. Scientists say that when the sun was first born, that is, when the sun was first formed, it was very large and had a lot of heat, light and gravitational mass. As the years pass, that is, not one or two years, friends, over many millions of years, the light and heat of our sun will gradually decrease as the nucleus of our sun fuses.

When the sun was first formed, hydrogen and helium were combined in the center of the sun through nuclear fusion, creating a large amount of heat, i.e. billions of degrees Celsius. There is also a large amount of hydrogen and helium in the nebula. When the sun was first formed, the sun did not have gravity, it just had heat and light. So, how did the sun get so much power? It is nothing more. Scientists say that when the sun was formed, the sun was affected by waves coming from the nebula nearby, and the sun got a large amount of gravity.
3. What is the sun shining on?
When the sun first formed, it was spinning very fast. When it was first formed, the sun was very hot. As many millions of years passed, the heat of the sun also decreased. Now the heat of the sun is at a steady state. In the beginning, the hydrogen and helium of the sun were spinning into the sun at a high speed. As many millions of years passed, the sun gradually moved away from our Milky Way Galaxy and now the sun is spinning the Milky Way Galaxy. But it takes many billions of years or millions of years for the sun to orbit our Milky Way once. Why is it normal for us to the sun, but for humans living on Earth, it is a long time. In another sense, what scientists say is that the sun is slowly moving away from our Milky Way galaxy. But we do not know how true this is. It is not only our sun, all the stars in the Milky Way galaxy are spinning around the Milky Way galaxy as a center. Each star has its own age, gravity, water, life, and all of these are separate.
There are billions of stars in our Milky Way galaxy, forming and dying, eventually becoming black holes.
4. Do you know how long the sun lives?
Scientists say that the other eight planets orbiting the Sun, as well as other small asteroids and rocks, all originated from the Sun. The total lifespan of our Sun is 10 billion years, and our Sun has already spent half of it, meaning that out of 10 billion years, about 4.6 billion years have passed, leaving only 5 billion years left.
But even though scientists say that our Sun's lifespan is approximately ten billion years, our Sun may be destroyed before that. Otherwise, nuclear fusion may occur in our Sun even after ten billion years and create light and heat. This will take many millions of years to happen.
Our sun is gradually passing its age. Our sun is also getting old. But the sun will not disappear immediately as we think. There are still five billion years until the sun disappears, that is, the sun dies. No one can imagine what our earth will be like at that time. Because there may be no trees on our earth, or there may be no water, or our earth may be covered with forests. Whatever you want, it can happen.
5. Can we go closer to the Sun?
No, we cannot go near the sun. Because there are millions of degrees of heat and light coming from the sun. This is because of the nuclear fusion that occurs in the center of the sun. Because there is a lot of heat coming out of the sun, millions of degrees Celsius. If that were the case, we would immediately burn up and become ashes as we go closer to the sun. Not only humans, but no object can go near the sun, that is, no man-made object can be brought close to the sun. However, in the future, scientists may find a spacecraft that can go near the sun, and we hope that scientists can travel in it and study the sun as well.
Conclusion
As I said above, we have read and learned that our giant star, the Sun, was born from a nebula that has spread over the Earth. I believe this will surprise us and stimulate our imagination. Let us protect our Earth in the present time. Let us consider it our duty to keep our Earth safe. See you again with another interesting and scientifically rich space-related post. Thank you.
