Why do we see stars together in the galaxy, what is the science behind it?


If you live in a city like Delhi, you will hardly be able to see stars at night. But if you live in a hilly area, then at night you will not only be able to see the stars, but sometimes you can also see the Milky Way. Apart from this, you can also see the galaxy in the pictures taken by NASA or ISRO. If you look at these pictures, you will see that the stars are visible together. For example, the stars are very close to each other.

However, in reality they are millions and crores of kilometers away from each other. Let us know that the Milky Way, which we also call the Galaxy, is a huge structure which includes billions of stars, planets, gas, dust, and dark matter. When we look at the night sky, we see many stars shining together. But what is the science behind it? Let us understand it in detail.

What is a galaxy like?

A galaxy is a spherical or ring-shaped structure, which contains thousands of millions of stars together. The galaxy we are a part of is known as the Milky Way, which is a spiral galaxy, in which the stars are arranged in a disk.

Why do the stars appear together

The simultaneous appearance of stars in the galaxy depends on many factors. For example, when we see stars, we are only seeing the light of those stars, which reach us after a very long time. In simple language, the stars are actually very far away from each other, but their light. When they reach our eyes, they appear to us together.

This does not apply only to stars, if something is in large quantities and is located at some distance from each other, then it If we look from a distance, we can see them stuck together. For example, when you see your locality in a video taken from a drone from high above, the houses appear close together, but in reality there is a distance between them.

The ability of the eyes and Brightness of stars

Actually, the stars in the galaxy appear closer to each other because our eyes have certain limits. That is, the ability to see with our eyes is limited to a certain distance and we can only see the light that reaches the earth. In such a situation, when many stars shine together, the combined light of all reaches the Earth simultaneously, due to which we feel that they are together.
