Recently, an international team led by Xu Cong, a researcher at the National Astronomical Observatories of the Chinese Academy of Sciences, used the "Chinese Sky Eye" to discover the largest atomic gas structure in the universe to date, 20 times larger than the Milky Way.
In the vast universe, human beings have always been full of curiosity and longing for that mysterious starry sky. In order to explore the mysteries of the universe, many advanced ray astronomical telescopes have been built in the world.
So, what are the world's largest astronomical radio telescopes, do you know that China's Sky Eye is not the largest?
5th place: Canadian Hydrogen Intensity Mapping Experiment (CHIME): A radio telescope built in Canada and located in the Okanagan Valley of British Columbia. It consists of four antennas with a caliber of 100 meters.
4th place: European VLBI Network (EVN): A network of radio telescopes built by several European countries, consisting of multiple telescopes distributed throughout Europe. The maximum caliber of the network is 300 meters.
3rd Place: Arecibo Observatory, USA: Located in Puerto Rico, it is one of the largest radio telescopes in the world, with an aperture of 305 meters.
Second place: China Sky Eye (Five-hundred-meter Aperture Spherical radio Telescope, abbreviated as FAST): A radio telescope led by the National Astronomical Observatories of China, with an aperture of 500 meters, located in Dawotai, Jinke Village, Kedu Town, Pingtang County, Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province. It was officially inaugurated on September 25, 2016.
1st Place: Russian RATAN-600 Radio Telescope (RATAN-600): Located in Zelenchuk, Russia's Caucasus, it is the world's largest single-disc aperture radio telescope with a diameter of 600 meters.
These radio telescopes are among the most advanced radio observation equipment in the world, and their construction and operation are of great significance for promoting the development of radio astronomy and mankind's understanding of the universe!
