When we learn about the mysteries of the universe in order to know about the world of stars and their life cycle and the celestial body Quasar, today is the turn of the galaxy. What is this type of galaxy and how it is formed, in this interesting article:
How much do you know about Galaxy

Peninsular Universe: Galaxy


When we see the sky full of stars in the night, we get energized by the splendor of its splendor. If we look in the sky in a village, then it is even more enjoyable, because in the villages there is less dazzle of light in the villages and the environment is clean and peaceful.

When we observe the sky every day, we slowly start to realize that neither does the light of all stars be alike nor the color of them. All the stars and star clusters we can see with our naked eyes are all members of a very comprehensive plan, which appears to be in the sky almost equal to the river stretching from north to south. This is called 'galaxy' or 'galaxy'.

If we define the galaxy in the scientific language, then we can say that it is a group of stars which are interconnected due to their own gravity. Ancient astrologers only considered the white stripes visible in the sky only as a galaxy. But today we know that in addition to billions of stars (most of which do not show with the naked eyes), our Earth, the Moon, all other planets, the moon (natural satellite) of all the planets, Meteoroid and All other members of the solar system are included. This is also called the 'Peninsular Universal' due to the vastness of the galaxy.

There are millions of billions of galaxies in our universe. In each galaxy there are also large clouds of gases and dust in addition to stars. These huge clouds are called nebula in starfish. 98% of the galaxy's total matter is made of stars and the remaining 2% is made of gas and dust clouds.

Classification of galaxies based on structure


Do you know that not all galaxies are the same? There are three types of galaxies depending on the structure - spiral, elliptical and column spiral.


Spiral Galaxy:

The structure of the spiral galaxy is the size of the disk. The central part of the spiral galaxies appears to be slightly raised. Outside the central part, two strange structures seem to have turned out. In this type of galaxy there are mainly hot and bright stars of 'A' and 'B' type. As we know, the life span of 'A' and 'B' types is very short. Therefore, we can say that there are fewer stars in the spiral galaxy. And here the new stars are also being built. Our galaxy is similarly structured. Our neighbors Mandakini Devyani (Andromeda) also has a spiral structure. Do you know that 80% galaxies are present in spiral structures in all galaxies present in the entire known universe.

Elliptical galaxies:

These types of galaxies are smooth and without any quirks. In the total galaxy known to the universe, approximately 17% of the galaxies are of this type of structure.

Column spirals and irregular galaxies:

The two spiral arms of galaxies of this type of structure appear to emerge from both ends of a straight column. This direct pillar passes through the center of the galaxy. Approximately 1% of the galaxies in this known galaxy are of this type of structure.

In addition to these three types of galaxies, about 2% of galaxies in the universe have irregular structures. Their size is irregular and they are small.

Our Galaxy: Milky way:

Our Sun and its family, i.e. the solar system that is a member of the galaxy, is named Milky way. To understand the size-type of the galaxy, imagine a flat roti, whose middle is slightly floral. Together with billions of stars, a huge scheme is formed, which is called 'Mandakini'. In reality, the galaxy is a mandrakini itself.

The diameter of our galaxy is approximately one million light-years and it has more than 100 billion stars; That is, its entire mass is equal to our 100 billion Suns. Our galaxy, i.e. lactose, is a member of a group of 24 galaxies called 'local groups'. Our Sun is about 30,000 light years away from the center of the galaxy.

Sun is rotating in the center of the galaxy at a speed of 220 kilometers per second. Sun takes about 25 million years to complete a revolution of the galaxy. The interesting thing is that during the entire existence of man on earth, the Sun has not completed any orbital of the galaxy.

In the early decades of the twentieth century, astronomers had such a belief that the entire universe was contained in our galaxy, but this assumption finally became completely wrong.

In 1924 an American astronomer Edwin Hubbal proved that galaxies exist in millions of crores of cosmos in the universe. After proving the existence of the other galaxies, Hubble spent observing his spectrum in later years and in the construction of the table.

Expanding universe:


Edwin Hubble concludes from his observations that galaxies are not stable in the universe, as their distance increases, the speed of their running away becomes faster.

This fact can be explained in the same way - assuming that galaxies are moving very large velocity away from us with light equal velocity. The galaxies are moving away and the universe is spreading. This has been known by the Doppler effect. Characters of all galaxies are moving towards the red end, that is, they are moving away from the Earth, if the galaxies were coming near the Earth, then there would be unnecessary baggy-displacement. So today many facts are indicating that the Universe is expanding like optical-velocity, in the same way as we inflate the balloon, then we see the distances moving between its dots.

In 2011, three astronomers from the Nobel Prize awarded by Saul Perlmutter, Adam G. Riess and Brian P. Schmidt concluded that acceleration in the speed of the universe's expansion was accelerating. That is, the universe is spreading not at the same speed but speed. The main reason for its acceleration is black energy. That is, the black energy is accelerating the expansion of the universe.

According to Hubble's findings, the velocity of a galaxy can be removed by the following formula:
                   Velocity of the galaxy = Hubble-constant x distance (V = Hxd)

We have come to know that so much that the universe is so much bigger in terms of distance, mass and era, that it is impossible to guess from the experiences of daily life. Therefore, it is necessary to resort to the eyes of mathematics and science. With the help of mathematics and science, we are doing celestial observation and will continue to do even in the future.
