While everyone is still immersed in the carnival of the 1-inch sole on the ground, scientists with space in mind have already set their sights on the largest camera in human history.
Recently, China Manned Space Engineering Officedirector Hao Chun introduced at a press conference that next year our country plans to launch the first large-scale space survey telescope. In the future, it will fly in co-orbit with China Space Station, bringing panoramic high-definition to the universe. Pictured, the telescope will become the largest "camera" in space after operation.
The sky survey telescope is very "impressive". It is as big as a bus and stands as high as a three-story building. Its aperture is two meters, which is equivalent to that of the Hubble Space Telescope in the United States, but its field of view is 350 times larger than that of the Hubble Space Telescope.
Why put telescopes in space? What can the largest camera in space capture?
Friends who use civilian telescopes should know that when observing space objects with a telescope, it will be affected by factors such as atmospheric meteorological conditions. Things seen under poor conditions will not be clear. A scientist once said that observing stars from the ground is like watching birds from the bottom of a lake. But there are no such interference factors when observing in space.
This telescope will help astronomers observe more than 1 billion stars, determine the location, shape, and brightness of these galaxies. It can also help astronomers draw a dark matter map of nearly 10 billion light years, thereby inferring what dark matter is and unlocks the universe. unsolved puzzle.
This matter NASA has already started as early as 1990. At that time, an optical telescope was placed in orbit. This is the Hubble Telescope that has been popular in recent days because NASA released the latest batch of high-definition images of the universe. Big picture, the Hubble Telescope has been working for 32 years now. The
sky survey telescope will work together with the China Sky Eye located in Guizhou Province, my country. One is in the sky and the other is on the ground, providing more technical conditions for our country to explore the unknown universe.
Before seeing the photos taken by the sky survey, let us first appreciate the latest picture of the universe released by NASA recently.
Carina Nebula
This star is located in the constellation Carina, about 7,600 light-years away. It is one of the brightest and largest stars in the sky, with a mass several times that of the Sun. This gorgeous infrared image shows hundreds of new stars we've never seen before, including bubbling jets of gas as new stars are born. Each point of light is an individual star, which may also have individual planets orbiting them.
Stephen's Quintet
This group of five galaxies is 290 million light-years away from us. There are millions to hundreds of billions of stars in each galaxy. Due to the huge gravitational force between them, they are tightly bound together.
SMACS 0723 galaxy cluster
SMACS 0723 galaxy cluster is about 5.12 billion light years away from the earth. It is filled with thousands of super galaxies like Milky Way . Its scale is dozens of times that of local galaxy cluster . The local galaxy cluster is composed of the Milky Way. A galaxy group composed of more than 50 galaxies including the adjacent Andromeda galaxy .
Since the SMACS 0723 galaxy cluster is about 5.12 billion light years away from us, the deep field image of Webb Space Telescope shows what it looked like about 5.1 billion years ago. Now, has the galaxy cluster disintegrated? It is still a unknown.
Whenever you are faced with the messy life and feel helpless, I suggest you look up and look at the stars.
The light emitted hundreds of millions of years ago will clearly tell you the shortness and insignificance of life.
Those obscure secrets and unattainable treasures are not as good as living in the present!
