500-meter spherical radio telescope (FAST). Its specific location is located in Dawodang, Kedu Town, Pingtang County, Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province. This depression is located at 25.647222 degrees north latitude and 0 106.85583 degrees east longitude, with a diameter of about 800 meters, 85 kilometers northeast of Pingtang County and 45 kilometers southwest of Luodian County.
The 500m spherical radio telescope is called "the 500m spherical radio telescope (FAST)", which was conceived by China astronomer Nan Zai 1994. It took 22 years to build and was put into use on September 25th, 20th16th. It is the largest single-aperture and most sensitive radio telescope in the world, which is led by the National Astronomical Observatory of Chinese Academy of Sciences and has independent intellectual property rights in China. The comprehensive performance is ten times that of the famous radio telescope Arecibo.
Since 20/kloc-0 was completed and put into use on September 25th, 2006, the 500-meter spherical radio telescope "500-meter spherical radio telescope (FAST)" has found 5 1 pulsar candidates, of which 1 1 pulsar has been confirmed as a new pulsar.
Extended data:
FAST, with China's independent intellectual property rights, is the largest and strongest single-antenna radio telescope in the world, and its design fully reflects China's high-tech innovation ability. It will provide opportunities for discovery and breakthrough in many basic research fields such as large-scale physics, deep structure and material laws of the universe, and will also play an irreplaceable role in solar-terrestrial environmental research, national defense construction and national security. Its construction will promote the development of many high-tech fields, improve the original innovation ability, integrated innovation ability and the ability to introduce, digest, absorb and innovate again. Its construction and operation will promote the economic prosperity and social progress in the western region, which is in line with the overall national regional development strategy.
With an antenna aperture of 500 meters, FAST will be the largest single aperture telescope in the world. Compared with Bonn 100m telescope, which is known as "the largest machine on the ground", the sensitivity is improved by about 10 times. If the celestial bodies are evenly distributed in space, the number of fast observable targets will increase by about 30 times. Compared with the American Arecibo 300-meter telescope, the sensitivity of FAST is 2.25 times higher. The working limit of Arecibo 20 zenith angle limits the ability to observe the sky, especially the network observation. It can be predicted that FAST will maintain the status of world-class equipment in the next 20-30 years, attract first-class talents and cutting-edge scientific research projects at home and abroad, and become an international astronomical academic exchange center.
