Deep in the mountains of Guizhou, astronomical engineers can sharpen the "eyes in the sky of China". Where exactly in Guizhou?

China Sky Eye is located in Kedu Town, Pingtang County, Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province.

Five-hundred-meter Aperture Spherical radio Telescope (Five-hundred-meter Aperture Spherical radio Telescope), referred to as FAST. Its specific location is in the karst depression 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 106.85583 degrees east longitude, with a diameter of about 800 meters. It is about 85km from Pingtang County to the northeast and 45km from Luodian County to the southwest.

The 500-meter aperture spherical radio telescope is known as the "China Sky Eye". It was conceived by Chinese astronomer Nan Rendong in 1994. It took 22 years to build and was inaugurated on September 25, 2016. It is built under the leadership of the National Astronomical Observatory of the Chinese Academy of Sciences, has my country's independent intellectual property rights, and is the world's largest single-aperture and most sensitive radio telescope. The comprehensive performance is ten times that of the famous radio telescope Arecibo.

Since its inauguration on September 25, 2016, the 500-meter aperture spherical radio telescope-"China Sky Eye" has discovered 51 pulsar candidates, 11 of which have been confirmed as new Pulsar.

Extended information:

FAST, which has China's independent intellectual property rights, is the largest and most powerful single-antenna radio telescope in the world. Its design comprehensively embodies my country's high-tech innovation ability. It will provide opportunities for discovery and breakthroughs in many fields of basic research, such as large-scale physics of the universe, deep-level structures and laws of matter, 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 original innovation capabilities, integrated innovation capabilities, and the ability to introduce, digest, absorb and re-innovate. Its construction and operation will promote economic prosperity and social progress in the western region and are in line with the country's overall regional development strategy.

FAST's antenna has an aperture of 500 meters and will be the largest single-aperture telescope in the world. Compared with the 100-meter telescope in Bonn, Germany, which is known as "the largest machine on the ground", its sensitivity is increased by about 10 times. If celestial bodies are evenly distributed in the universe, the number of FAST observable targets will increase about 30 times. Compared with the American Arecibo 300-meter telescope, FAST is 2.25 times more sensitive, and Arecibo's working limit of 20° zenith angle limits the observation sky area, especially the networked observation capabilities. It can be predicted that FAST will maintain its status as a world-class equipment in the next 20-30 years, and will attract first-class talents and cutting-edge scientific research topics at home and abroad, becoming an international astronomical academic exchange center.
