What is the impact of the major discovery of the Chinese Tianyan Telescope on the astronomical commu

The major discovery of the Chinese Tianyan Telescope is undoubtedly a great encouragement to China's astronomical community, and it has also allowed many astronomical researchers to find a direction. <>

1. China's Heavenly EyeChina has had a great interest in and research in astronomy since ancient times, and has often recorded various astronomical phenomena as early as ancient times, and has also invented many astronomical instruments. Although the study of astronomy has stagnated in modern times due to some reasons, fortunately, through the infinite efforts of astronomical researchers in China, a new breakthrough has finally been made in the field of astronomy. In particular, China's Sky Eye is known as the world's largest astronomical telescope, which has been stable and reliable since its operation, and has also achieved significant research results.

The discovery of many pulsars, as well as the ability to observe pulses at millisecond distances, is a particularly significant discovery for today's Earth-wide observation periods. <>

2. Major discoveries in astronomy, such as the fact that people can't see the rotation of the upper leaves when blowing a fan in the summer, and even if they use their mobile phones to capture the pictures, the images are blurry. However, the millisecond pulsars recorded by China's Sky Eye can be clearly photographed, which is enough to prove that China's Sky Eye breakthrough and functionality in this area are very powerful. This is because with this extra-large telescope, people's horizons have also been broadened to the universe, and China's astronomy has been at the forefront of the world, which is of great significance to China.

3. Let foreign astronomers look at China with admirationThe completion of this Chinese celestial eye not only has a significant impact on China's observation of phenomena and the study of extraterrestrial civilizations, but most importantly, it also allows foreign astronomers to affirm China's cultural research. Because in the past, China could only seek the help of foreigners to study space civilization, and in the past, telescopes could only see the edge of the universe, but now with China's Sky Eye, not only foreign scholars are impressed by China, but even China can occupy a dominant position in astronomy.

The impact is very huge, which is conducive to the development and leading of China in the field of astronomy in the world, and has made many contributions to the exploration and observation of the universe by human beings, attracting many scientists to study the data found by Tianyan.

This major discovery has enabled China's astronomical community to obtain important astronomical data and promoted the development of China's astronomy.

In fact, it has a very great impact on China's astronomical community and can enhance the status of China's astronomical community.

The astronomical telescope was invented by Galileo. In 1608, an apprentice of the Dutch spectacle maker Hans Ripach stumbled upon the idea that stacking two lenses on top of each other made it possible to see things in the distance clearly. In 1609, when the Italian scientist Galileo Galilei heard about this invention, he immediately built his own telescope and used it to observe the starry sky.

Since then, the first astronomical telescope has been born.

Galileo Gali.

He was an Italian astronomer, a physicist and engineer, and the founder of modern natural science in Europe. Gali is known as the "father of observational astronomy", "the father of modern physics", "the father of the scientific method", and "the father of modern science".

Galileo observed sunspots and the moon with a telescope.

Craters, Jupiter.

of the moons (Galileo moons), the waxing and waning of Venus, etc., these phenomena strongly supported Copernicus.

The heliocentrism says. Galileo's telescope was made using the principle of refraction of light, so it was called a refractor.

Since Galileo Galilei built the first telescope in 1609, telescopes have continued to develop, from optical bands to full bands, from the ground to space, telescopes have become more and more observant and can capture more and more celestial information. At present, human beings are expected to have telescopes in the electromagnetic band, neutrinos, gravitational waves, cosmic rays, etc.

China's largest astronomical telescope, Tianyan Weiyuanchun, is right. The "China Sky Eye" is currently the world's largest and most sensitive single-aperture radio telescope, capable of receiving electromagnetic signals more than 10 billion light-years away.

China, which started nearly 30 years later than the rest of the world in the field of radio astronomy, has built the world's most sensitive and largest (500 meters) spherical radio astronomy telescope (abbreviated as "FAST") in Pingtang County, Guizhou Province, which is known as "China's Sky Eye".

Details: This is a great project that embodies China's advanced science and technology, and it is a "giant eye to the sky".

The "Chinese Sky Eye" has a relatively strong sensitivity and can detect fainter celestial objects.

High sensitivity, thanks to its extremely compact design.

First of all, the platform feed cabin used to place the receiver-resistant celestial body signal system was creatively reduced to 30 tons by scientists, and was accurately positioned in the air by six steel cables more than 600 meters long, so that the error did not exceed 48 mm. The secondary fine adjustment of the parallel robot can achieve high-precision pointing tracking. Such engineering difficulty is unprecedented in the world.

Secondly, the reflective surface of the "China Sky Eye" is composed of 4450 reflective units. When the reflective surface is deformed, more than 2,000 hydraulic actuators move in tandem to drive 4,450 reflective units to be accurately positioned. This is similar to the compound eye of insects - both have the characteristics of large field of view and high sensitivity.

Most importantly, 6,670 main cables, 2,225 main cable points and the same number of drop-down cables constitute the world's largest span and highest precision cable net structure. This makes the reflective surface deform like an arm. In addition, the ultra-high fatigue resistant steel cable developed by the team has greatly improved the use value of "China Sky Eye".

Behind these world-renowned "intelligent manufacturing in China", there are countless painstaking efforts and sweat of Chinese scientific and technological workers represented by Nan Rendong.

A few days later, the world's largest single-aperture radio telescope, known as China's Sky Eye.

The 500-meter aperture spherical radio telescope.

FAST) will be officially open to the world and accept applications from scientists around the world.

FAST was developed by the late astronomer Nan Rendong in our country.

It took 22 years to build and its team is located in Qiannan, Guizhou Province.

Kedu Town, Pingtang County, Miao Buyi Autonomous Prefecture, where the unique karst landform.

and its surroundings are perfect for a fast home.

In order to better solve the design of ultra-large span cable net installation scheme and ultra-high fatigue performance steel cable.

The technical difficulties that the R&D team needs to overcome are self-evident in the problems of structure development and ultra-high-precision cable structure manufacturing process, and finally it took a year and a half to finally complete the technical research in the repeated "failure-understanding-modification-improvement". Many technical problems such as the design, manufacture and installation process of the cable net were overcome.

2. The high accuracy of FAST is also a big problem. Researchers make FAST run well. The machine is used to give the data accurately and efficiently the coordinate value of the cable net node of the reflective surface element.

To quickly obtain a 3D model and a 2D drawing of all the emitted surface elements, simply change the cable net coordinate values. Moreover, the surface accuracy of millions of single sub-units can be finally controlled at more than 1mm, which can be seen the painstaking efforts of Chinese researchers.

FAST is one of China's independent intellectual property rightsBasic SciencesTechnical Engineering. It is also the world's largest single-aperture and most sensitive radio telescope.

The opening of "Sky Eye" has enabled Chinese scientists to better explore the mysteries of the universe and the origin of life.

A big step forward. The openness of "Sky Eye" is inevitable, and only in the cooperative research with scientists around the world can we better develop and surpass. I believe that in the near future, FAST will bring us a more colorful cosmic world.

The Chinese Sky Eye was conceived by Chinese astronomer Nan Rendong in 1994. It took 22 years to build and was put into use on September 25, 2016. Led by the National Astronomical Observatories of the Chinese Academy of Sciences, it has the world's largest single-aperture, most sensitive radio telescope, with independent intellectual property rights in China.

Its comprehensive performance is ten times that of the famous Arecibo radio telescope. Nan Rendong, the chief scientist of the project, a researcher at the Chinese Academy of Sciences and the National Astronomical Observatories, held a conference in Shanghai on the "China"The 2006 annual meeting of the Astronomical Society said that compared with the existing 100-meter telescope with the largest aperture in the world, its observation capability has increased tenfold, and it will maintain its leading position in the world in the next 20 30 years.

The aperture of the Tianyan telescope is 500 meters, which greatly improves the distance and accuracy of astronomical observation, and is a major national scientific and technological project.

So what exactly is China's Tianya detecting? In fact, the first type is black hole radiation. But we know that the universe is an infinite number of black holes, and radiation is not something you can detect if you want to, and sometimes it depends on the question of opportunity.

Therefore, if there are really many black holes in the universe, then the signal emitted by it will definitely be the first to be captured by China's Sky Eye. And now the main achievement of the Chinese Sky Eye is the knowledge detection of pulsars. So far, China's Sky Eye has explored 47 pulsars in the universe, making it the country with the largest number of exploratory pulsers in the world.

And China's Tianyan has never stopped exploring the universe.

It has made a major breakthrough in China's astronomical research and comprehension, and has improved China's influence in astronomical comprehension.

A number of famous moons were discovered, and these satellites were named.

China's Sky Eye has detected black hole radiation.

Let China's astronomy advance by leaps and bounds.

Outer space changes can be observed over a longer period of time.

Many planets, comets and celestial bodies have been discovered.

Able to see more fully into the unknown.

Stars have been observed far away for China.

It can observe outer space more comprehensively and accurately.

The most common introduction: The question of who invented the world's first astronomical telescope has long been determined in the history of science and technology, and he is the Italian scientist Galileo. But Galileo denied this, saying that Galileo was a Dutchman, and that the world's first telescope was built in 1608 by Hans Lee, an unknown optician in Middelburg, the Netherlands.

Galileo telescope.

Primitive astronomical telescope.

One day in the early 17th century, Hanslippershey, the owner of an optical shop in a small Dutch town, in order to check the quality of the polished lens, arranged a convex lens and a concave mirror in a line, looked through the lens, and found that the church spire in the distance seemed to be getting bigger and closer, so he accidentally discovered the secret of the telescope. In 1608 he patented a telescope he had made, and in compliance with the authorities' request, he built a binocular. It is said that dozens of opticians in the town claim to have invented the telescope, although it is generally believed that Lieberch was the inventor of the telescope.

The news of the invention of the telescope quickly spread throughout Europe, and the Italian scientist Galileo Galilei learned of the news and made one. The first telescopes could only magnify objects by a factor of 3. A month later, he built a second telescope that could magnify 8 times, and a third that could magnify up to 20 times.

In October 1609 he made a telescope capable of magnifying 30 times. Galileo observed the night sky with a homemade telescope and discovered for the first time that the surface of the moon was uneven, covered with mountains and with the cracks of volcanic craters. Since then, the four moons of Jupiter, the sunspot motion of the sun, have been discovered, and the conclusion that the sun is rotating.

At about the same time, the German astronomer Kepler also began to study telescopes, and he proposed another kind of astronomical telescope in "Refractive Optics", which consisted of two convex lenses, unlike Galileo's telescope, and had a wider field of view than Galileo's telescope. But Kepler did not build the telescope he introduced. Scheina made the first telescope between 1613 and 1617, and he also built a telescope with a third convex lens at Kepler's suggestion, turning the inverted image of the telescope made of two convex lenses into a positive image.

Shaina made eight telescopes and looked at the sun one by one, and each one could see sunspots of the same shape. Therefore, he dispelled the illusion that many people thought that sunspots might be caused by dust on the lens, and proved that sunspots were indeed observed to be real. While Shayna was observing the sun, he was wearing special blackout glass, while Galileo did not have this protection, resulting in an eye injury and nearly blindness.

In order to reduce the chromatic aberration of the refracting telescope, Huygens of the Netherlands made a telescope with a barrel length of nearly 6 meters in 1665 to explore the rings of Saturn, and later made a telescope with a length of nearly 41 meters.

Modern astronomical telescopes.

All of the above are optical telescopes. However, with the advancement of science and technology, a series of special telescopes have been invented, such as infrared background radiation telescopes, radio telescopes, etc. It is worth mentioning here that the world's largest radio telescope is currently China's FAST.
