Each of the five wonders of the universe surprises us and laments the beauty of the universe.

In the eyes of many people, the universe is dark and silent, and beautiful scenery cannot be seen. In fact, in the lens of astronomical telescope, behind the dark universe is a beautiful and wonderful world.

The vastness of the universe brings us a dark and mysterious intuitive experience. But when you really understand the universe, you will find that there are many miracles in the universe, and each miracle can bring us a good feeling. Let's look at five of them.

First of all, the charming 30 swordfish constellation

30 Swordfish constellation is located behind Tianma constellation, about 654.38+0.7 million light years away from us, and was born in a very active star region. There are a lot of dust and gas around the constellation and many new stars. Seen from a distance, 30 swordfish constellation has a unique and beautiful style.

Second, supernova remnants

I believe many friends know that stars also have their own life cycle, and they will go to the end of their lives as time goes by. However, stars with different masses present different scenes at the end of their lives. Yellow dwarfs like the sun behave moderately at the end of their lives, and will evolve into white dwarfs after the red giant stage.

When a star whose mass exceeds that of a yellow dwarf like the sun comes to the end of its life, there will be a big explosion, which we call a supernova explosion. After the supernova explosion, some celestial bodies and other various substances will be left behind. These expanded celestial bodies and substances are called supernova remnants.

Perhaps in the eyes of many people, supernova debris is the corpse product of massive stars, which will make us feel scared, but in fact, supernova debris has various shapes, although there are great differences, but each type of supernova debris is extremely beautiful.

NASA Hubble Telescope and Chandra X-ray space probe observed a beautiful ring-shaped supernova remnant in the deep space, and the X-ray data recorded the shock wave of supernova heating the surrounding gas.

Third, the star snow angels.

The most common structure in the universe is nebula, which is the birthplace of stars. Different nebulae are very different. Some nebulae are also wonders of the universe and look particularly beautiful.

About 2000 light years away from the earth, there is a breeding ground for stars, which is an unusually spectacular and beautiful nebula. Scientists call it "snow angels".

Fourth, spiral galaxies.

Galaxies are the basic structural units in the universe. It consists of stars, planets and a lot of gas and dust. There are two main shapes of galaxies, one is a disk and the other is an ellipse.

Disk galaxies, also known as spiral galaxies, are shaped like pancakes and are the most numerous galaxies in the universe, such as the Milky Way and Andromeda galaxies.

Elliptic galaxies formed earlier in the universe. They don't rotate like disk galaxies, but move more randomly. Scientists believe that elliptical galaxies are the product of galaxy merger. When two galaxies with similar mass merge, their respective stars pull each other under the action of gravity, which disturbs the motion of the stars and forms random orbits.

So what is a spiral galaxy? In fact, it is another name for a disk galaxy. The system structure of spiral galaxies is more stable, and the operation of stars is more stable, which is more conducive to the evolution of life planets. Therefore, in theory, the galaxy where intelligent civilization is located basically belongs to spiral galaxies, not elliptical galaxies.

V. Habig-Harrow 1 10 Celestial Bodies

This is an amazing observation of the Hubble Space Telescope on the complex and slender gas beams in Habig-Harrow1Kloc-0/0 celestial bodies (the density is hundreds of millions of times lower than the smoke in the earth's atmosphere), and their polar regions release airflow.

There are countless wonders in the universe, and what we can observe at present is only the tip of the iceberg. In the depths of the unknown universe, there may be more mysterious and beautiful wonders of the universe. With the rapid development of human science and technology, I believe that in the near future, we can find more beautiful wonders, and look forward to one day, we can go to the field to observe and take a closer look at the beautiful style of these wonders.
