There is only one Tianyan left in the world, China s FAST, why is China s Tianyan so strong?

First of all, we must understand that the Arrecio radio telescope that collapsed this time was built in 1963. It's been almost 60 years now, and he's close to retirement before that, so no one has been repairing him. But in this case, a lot of his equipment is aging, and in the past two years, typhoons have been hitting the area, so many parts have actually broken.

Under the assumption of the American Astronomical Bureau, he will be scrapped soon, so that he can retire completely, but he didn't expect it. On such an ordinary night, the astronomical telescope that has accompanied us humans for nearly 60 years collapsed automatically. <>

Our Sky Eye is actually much stronger in function than the current Arecibo telescope, mainly because with the development of science and technology, the future functionality will definitely be considered first in construction. We must first understand what the device is used for? Although its name is telescope, it is actually different from the optical telescope we usually see, and it mainly captures those radiation signals in the universe.

Through these signals, we can analyze some information about distant objects, which in turn helps us understand the surrounding objects. <>

At present, our Sky Eye system has just been completed, and the Arecibo radio telescope has been decommissioned. To be honest, there is a sense of heroic sympathy, after all, both are fighting for the future of mankind, and geographically, our Sky Eye telescope is at a low latitude, while the Arecibo telescope is at a mid-latitude, and the two can actually learn from each other in terms of geographical location. But it was clear that there would never be such an opportunity to see the two outer diameters working together.

At present, our Sky Eye system is the largest radio telescope in the world, with an aperture of 500m. With the help of radio telescopes, we can discover the mysterious existence of gravitational waves, and hopefully in the future. The eye of the sky can help us bring more miracles.

Because China is very powerful. China has spent a lot of manpower, material and financial resources to build and maintain this eye in the sky. Only a strong country can do it.

This is inseparable from China's support for science and technology, as well as a steady stream of talent. As a huge project, no one slackens, but has always persevered, which is an important reason for the success of China Tianyan.

Because China's Tianyan is forged by the painstaking efforts of countless people. Not only are there many scientists, who are measuring and estimating day and night, but there are also many unknown workers who are working hard to build. That's why China's Tianyan can stand so strong.

China's Sky Eye has a diameter of 500 meters wide, and 132 high-quality pulsar candidates have been discovered using the Sky Eye, of which 93 have been confirmed as pulsars.

Because Tianyan is made by a very powerful technical team, and it takes a lot of effort, then these people's minds are very intelligent, so Tianyan is also very strong.

I think it's mainly because of my country's excellent technology, so my country's Tianyan will be so strong.

Because China's Tianyan adopts many high-tech in China, and there are professional maintenance personnel to overhaul and debug to ensure the operation of Tianyan.

Because China's Tianyan has very strong scientific and technological strength, it is a generation of scientific researchers who have worked hard for decades to research.

Because now China pays more and more attention to quality, we have also suffered a lot of poor quality losses, so the later requirements for construction is that the quality must be good, China Tianyan is a national project, and the quality must be good.

It may be because China's science and technology itself is very powerful now, and the positioning is also very accurate.

It can better understand the universe, expand the horizons of human beings, and allow human beings to better understand the universe and make better observations.

The significance and function lies in the all-round monitoring of space, and the effect is also very positive, and it will also bring great changes to the follow-up research and space exploration.

It was installed in Guizhou Province. Because from the point of view of this kind of equipment, the environmental requirements are very high, and after careful consideration, it was finally settled in Guizhou Province. Tianyan himself design has extremely strict requirements for accuracy, and the degree of requirements is very fine, so how to overcome the terrain and temperature difference, this welfare condition is a very big problem of the Tianyan project, after the project team constantly changed the plan to think of countermeasures, and finally put forward a plan, and this solution can solve these big problems, and in the design of the way is also conducive to the telescope to adjust the angle, and then in order to pass through the uniform temperature, The calculation and measurement process alone took more than four months.

Therefore, China Tianyan project has put in a lot of hard work behind it.

Because there is a limit in the scientific community, this limit is called the 100-meter limit, because from the perspective of the sky-shooting eye, as long as the aperture of the radio telescope exceeds 100 meters, it is very difficult to achieve its high precision, because this is also a world problem, so in order to ensure that the sky eye has high precision. In order to ensure the accuracy of his cable net, the strict error can not exceed one millimeter during construction, which is a very demanding requirement, because one millimeter is only a little less than a little bit for the steel cable, which is difficult to grasp, but this time it is strictly implemented and grasped, because this time it is necessary to achieve a very high accuracy.

Because high accuracy also means high sensitivity, and compared with the American radio telescope, its effective contact area is at least doubled, and the sensitivity is greatly greater than the latter, and the reflective surface of the eye can also adjust the shape in real time. This is the only telescope in the world that can actively change its position.

The original design concept was derived from the American Arecibo telescope, but compared with the American telescope, the active reflector system is the biggest innovation of our country's Sky Eye. This also greatly improves the efficiency of observation. Because the American telescope is fixed, they only scan the sky in a 20-degree band, but the Chinese Sky Eye, an active reflective surface radio telescope, has a wider range of observation and a wider angle.

China's Tianyan telescope, some radio telescopes in other countries, the comprehensive performance has been improved by more than 10 times, this is China's technology, this is also made in China, and it is a very remarkable project in our country. With the completion of this radio telescope, we will be able to better listen to the sounds coming from the deepest depths and effectively uncover the secrets of the universe.

China's Tianyan FAST is installed in Guizhou Province, behind the Tianyan, there are a lot of stories, China has made a lot of efforts in order to develop the Tianyan, and has also poured a lot of scientists' efforts.

In Guizhou Province, Tianyan is located in the deep mountains, the rainy season is long, mosquitoes are flying, and the living conditions are poor.

China Sky Eye is installed in Guizhou Province. The story behind China's Sky Eye is that the chief designer died without waiting for the moment of the opening of Sky Eye.

Is Sky Eye Fast a project? Why?

The Sky Eye FAST 500-meter Aperture Spherical Radio Telescope (FAST) is a major scientific and technological infrastructure construction project of the National "Eleventh Five-Year Plan", and is the world's largest single-aperture and most sensitive radio telescope with China's independent intellectual property rights, known as "China's Sky Eye". Science has reported on the progress of FAST four times, and Nature has listed the completion of FAST as a scientific event with significant global impact in 2016. The telescope will provide new opportunities for major scientific discoveries in pulsar search and neutral hydrogen patrol, and is of great national strategic significance in incoherent scattering radar, deep space detection and communication.

From the idea of building FAST in 1994, to its inauguration and commissioning in 2016, to today's completion of commissioning and a series of scientific achievements.

Currently, the world's largest radio telescope, FAST, belongs to China, and it has a resounding name in China"China Sky Eye"。It is precisely because of its existence that China has changed from catching up in the past to surpassing in the field of astronomical research, and has suddenly made us from backward to one of the strongest in the world's astronomy.

In just a few years since its launch, China has taken a leading position in the field of astronomy, discovering numerous stars, neutron stars and pulsars, and even imperceptible black holes. However, China's Sky Eye also has its drawbacks, because it belongs to radio telescopes, so it can only observe distant starry sky, it can detect stars, pulsars and even black holes hundreds of millions of light-years away, but it is helpless for those near-Earth asteroids that cannot emit radio waves.

It is for this reason that its existence is widely questioned, but in fact it is just a misunderstanding. In cosmic exploration, near-earth exploration is relatively easy, and the farther away the starry sky, the more difficult it is to explore, and it is difficult for China's Sky Eye to be surpassed in a short period of time.

Since September 2016, when China's Sky Eye was put into use, 43 pulsars have been discovered one after another, and the pulsar arrival measurement accuracy has been improved from 120 nanoseconds in the past to 30 nanoseconds today, becoming the most accurate pulsar timing array in the world.

China's Sky Eye also has a more powerful function, if there is alien information in the galaxy, we will soon be discovered, which makes the chief scientist of the international project to search for aliens Dan Wassimo want to cooperate with us to search for aliens together. This made many American astronomy enthusiasts very jealous"Good radio telescopes have been broken for the Chinese, it makes people want to go crazy! "
