Why is the world's largest single-aperture radio telescope located in the mountainous area of Guizhou?

In order to better protect the world's largest single-aperture radio telescope located in Pingtang County, Guizhou Province and create a good electromagnetic wave environment, Guizhou Province will relocate nearly 10,000 people in its core area this year.

The world's largest single-aperture radio telescope-500-meter spherical radio telescope (FAST) is located in Jinke Village, Kedu Town, Pingtang County, Guizhou Province, southwest of China. This is the first major national science and technology infrastructure built in Guizhou Province, and this telescope will help people find dark matter and even aliens.

Since 1994, scientists in China have been choosing a site for FAST and finally chose Dawodang depression in Jinke village. This is a natural depression, which can hold the reflecting surfaces of 30 football fields of FAST, and it is far away from the city and has a good radio environment.

The reporter learned from the Guizhou Provincial Political Consultative Conference that the core area within 5 kilometers around the FAST project involves 9 households110 people in Pingtang County and Luodian County of Guizhou Province. Guizhou province decided to integrate funds to relocate these 2029 households as a whole and give subsidies.

Among them, the Guizhou Provincial Reservoir and Ecological Immigration Bureau gives subsidies according to the standard of 6.5438+0.2 million yuan per person; Guizhou Provincial Committee of Religious Affairs gives subsidies to ethnic minority families with housing difficulties according to the standard of 6.5438+0 million yuan per household; On 20 16, the Department of Housing and Urban-Rural Development of Guizhou Province included eligible farmers in the scope of rural dilapidated buildings renovation.

The cost of FAST is 65.438+0.2 billion yuan. Observer. Com previously reported that the feed cabin, the core component of FAST, was upgraded for the first time on June165438+1October 2 1 last year, marking the end of the whole project. This "giant eye looking at the sky" is expected to be completed in September 20 16, and it will begin to explore the mysteries in the depths of the universe.

For scientists, FAST is of great scientific significance. It will be possible to search for more exotic celestial bodies to observe pulsars and explore the origin and evolution of the universe, dark matter and dark energy, galaxies and the evolution of galaxies. And even search for interstellar communication signals and explore extraterrestrial civilization.
