[The world's largest Telescope] The clarity of the world's largest Telescope in the world is ten times that of Hubble
In 1995, Chinese astronomers proposed the idea of building a 500 -meter -caliber spherical sphere in the Karst depression, and was located in Dawo in Pingtang County, Qiannan Prefecture, Guizhou Province.In 2007, the project was approved by national approval and became one of the nine major scientific and technological infrastructure in my country.fastEssence
Fast is called FIVE HUNDRED Meters Aperture Spherical Telescope (500 -meter -caliber spherical radio Telescope). It uses the unique terrain conditions of the unique design of Chinese scientists and the unique terrain conditions of the Karster depression in southern Guizhou, my country to build a high -sensitive giant radio electricity with a large high -sensitivity of about 30 football fields. Telescope.Compared with the 100 -meter Telescope of Germany, which is known as the "largest machine on the ground", FAST has increased by about 10 times the sensitivity; the United States ARECIBO 300m Telescope, which was ranked as the top ten projects in the 20th century project of the 20th century of the human 20th century,Compared with, its comprehensive performance has increased by about 10 times.As the world's largest single -caliber Telescope, Fast will maintain the status of world -class equipment in the next 20 to 30 years.
The FAST project has three major independent technological innovations: first, the first time in the world uses natural landform construction to build a giant Telescope; the other is to use active reflex surface technology.Innovation is a light cable dragging feed source support technology, reducing the 10,000 -ton platform to dozens of tons, achieving a millimeter -level dynamic positioning accuracy.The world's largest Telescope was officially put into use at the end of September 2016 and was open to the world. Astronomers in many countries have submitted a research and observation plan.
Profound meaning
As a multi -disciplinary basic research platform, FAST has the ability to extend neutral hydrogen observation to the edge of the universe, observe dark matter and dark energy, and find the first generation of celestial bodies.It can find about 7,000 pulse stars in one year, and study the material structure and physical laws in extreme state; there is hope to discover strange stars and quark stars; discover the neutron star -black hole double star, no need to rely on the model to accurately determine the quality of black holes; accurately through preciseThe reaching time of the determined pulse star to detect gravitational waves; as the largest station, add the international long baseline network to form a imaging image for the super fineness of the celestial body; it may also find that the high -red movement of the galaxy is also found.Observation breakthroughs; used to search for identifying possible interstellar communication signals, looking for external civilization.
Fast has important application value in major national needs.The Chinese space measurement and control capacity is extended from the Earth synchronization track to the outer edge of the Solar system, and the downward rate of deep space communication data is 100 times.The measurement accuracy of pulse stars has increased from the current 120 -nan seconds to 30 nan second seconds, becoming the most accurate pulse chronograph internationally, making pulse star clocks for independent navigation.Perform high -resolution microwave inspections, diagnose and identify weak space signals with a resolution of 1Hz, and serve national security as a passive strategic radar.As a non -related scattering radar receiving system for the "Wuwu Project", it provides high -resolution and high -efficiency ground observations; tracking and detecting the throwing of the coronation material to serve the space weather forecast.
Fast research involves many high -tech fields, such as antenna manufacturing, high -precision positioning and measurement, high -quality radio receiver, sensor network and intelligent information processing, ultra -broadband information transmission, massive data storage and processing.FAST key technical achievements can be applied to many related fields, such as large -scale structural engineering, high -precision dynamic measurement, large industrial robot development, and multi -wave radar device.FAST's construction experience will have an impact on the development of my country's manufacturing technology towards informationization, limit, and green.
With Fast, the remote and occluded Qiannan Karst Mountains will become the world's attention to the international astronomical academic center, becoming a new window that shows Guizhou to the world.The astronomical science popularization base with Fast as the main body will promote popular science work in western my country and even the whole country, educate young people, publicize the public and decision -making Levels, and serve the long -term strategic goals of science and education.
