Show you the deep space universe in the eyes of Hubble telescope. Every photo is so beautiful.

A galaxy is a huge celestial system composed of many stars. In the early days, due to observation technology, humans thought that there was only one galaxy in the universe, the Milky Way. However, with the development of astronomy and the appearance of telescopes, people began to realize that the Milky Way is not the whole structure of the universe, and there are other galaxies besides the Milky Way.

Kant and Wright first put forward this view. At that time, people have found that in the dark night sky, in addition to the glowing stars, there are some cloud-like celestial bodies. They think that these celestial bodies may be composed of a large number of stars, thus putting forward the universe island hypothesis.

However, because there was no evidence to support it at first, the universe island hypothesis was not convinced. It was not until the famous astronomer Edwin Hubble discovered it through the Hooke telescope that he finally confirmed that there were countless other galaxies outside the Milky Way.

Today, astronomers estimate that there are at least 200 billion or even trillions of galaxies in the whole known universe, and all this is due to the advanced Hubble telescope, which is named after Edwin Hubble.

At present, the photos of galaxies owned by human beings are basically taken by Hubble telescope. Today, let's take a look at the beautiful pictures of deep space galaxies in the eyes of Hubble telescope.

As one of the most classic pictures of galaxies, Andromeda galaxy, the largest galaxy nearest to us, was taken.

Andromeda galaxy is about 2.54 million light-years away from the earth, much larger than our Milky Way, with a diameter of 220,000 light-years. This is a 65.438+0.5 billion pixel photo taken by Hubble telescope, which is full of stars. Scientists estimate that the number of these stars is at least close to one trillion.

This is a spiral galaxy, numbered M5 1. The spiral galaxy is located in the constellation Canis in the northern sky, about 23 million light years away from the Earth and 60,000 light years in diameter. There is a smaller companion galaxy next to him, which is merging under the action of gravity.

This is the famous NGC 4594 galaxy, which is also called the straw hat galaxy because it looks like a straw hat brought by Mexicans. Straw hat galaxy is located in Virgo, about 29.3 million light years away from the earth. Its uniqueness lies in its spectacular dust ring. If we enter its interior, we will find that there are a large number of young bright stars, with a dense globular cluster at its center.

This is the mouse galaxy, located in the back seat, about 290 million light years away from the earth. Mouse galaxy is a galaxy composed of two spiral galaxies, which are colliding and merging with each other. Gravity makes them interweave and merge with each other, thus forming two long tail belts, which will eventually form a larger new galaxy over time.

This is the windmill galaxy in Ursa Major. It was first discovered by French astronomer Pierre Xiangmei. The windmill galaxy is about 26,543.8+billion light years away from the Earth, with a diameter of 65,43.8+0.7 billion light years. It is very similar to our Milky Way, and it also has many spiral arms.

This is Andromeda's Ap 273, and it is also a galaxy that is colliding and merging, 300 million light years away from the earth. The Ap 273 galaxy is beautiful. The distance between the two galaxies is tens of thousands of light years. They formed a blooming rose in the collision, so they were also rated as one of the most beautiful galaxies.

This is NGC 3256 galaxy, located in the constellation Vela, about 1 100 million light-years away from the earth. NGC 3256 is already a large galaxy after the fusion of two galaxies, and the stars inside are extremely brilliant. Due to the continuous collision of nebulae in the process of fusion, a large number of new stars are born.

This is a tadpole galaxy, located in Draco. It is 280,000 light years in diameter and 400 million light years away from the Earth. The most unique feature of tadpole galaxy is its slender tail, which looks like a tadpole. Scientists speculate that this may be caused by the invasion of a dense galaxy.

This is the wheel galaxy and a new galaxy after collision and fusion, with a diameter of150,000 light years. We can see that it looks like a wheel, so it is called a wheel galaxy. He is located in Jed, 500 million light years away from us.

This is a Hartmann celestial body, a famous ring galaxy with a diameter of 654.38+ million light years. It is famous for its peculiar appearance. Its outer ring is made up of blue stars and its middle is made up of ancient red stars, about 600 million light years away from the earth.

In fact, there are many beautiful galaxies in our universe, and this is only a very small part in the eyes of Hubble telescope. Let us sigh that the universe is so vast.
