Where is the most advanced and largest astronomical telescope in China?

China's largest astronomical telescope has settled in Lijiang, Yunnan. This is a giant astronomical telescope with a diameter of 2.4 meters. It is the largest in the Far East, but unfortunately it is made in England.

But the record was soon broken.

According to the National Development and Reform Commission, after 13 years of investigation and sky survey, astronomers at home and abroad announced that the next generation of the largest radio telescope project will be put into use in Pingtang, Guizhou, China. This "cauldron" with a diameter of 500 meters and a receiving area equivalent to 25 football fields will be the largest radio telescope in the world at present. Its shape is similar to a cauldron satellite antenna, and it consists of 2000 reflectors with an area of15m. The total investment will reach 672 million yuan. It is understood that at present, the largest radio telescope in the world is the 305-meter Ali Xibe telescope built in the United States.

According to the Guangzhou Daily, the world's top and most advanced astronomical telescope model independently developed by China scientists was exhibited for the first time at the Hi-Tech Fair. This kind of telescope with the largest aperture in the world can observe tens of millions of galaxies, quasars and other extragalactic celestial bodies, which helps to uncover the mysteries of stars, star families and the structure of the Milky Way, and marks that the research of large-field astronomical telescopes in China has begun to lead the world.

According to experts in the field of high-tech fair, this astronomical telescope was independently developed by Chinese scientists after 10 years and cost 235 million yuan. At present, it is being installed and debugged at Xinglong Observation Base of National Astronomical Observatory in Hebei Province. It is expected to be put into use in 2008, when it will become the largest optical telescope with large aperture and large field of view in the world.

The reporter saw the miniature of the telescope at the high-tech fair. Experts told reporters that this is the first time the model has appeared to the public. The model looks ordinary, but it is endless. Unlike ordinary optical telescopes, it captures the spectra of stars instead of seeing their faces. One observation can obtain the spectra of 4000 celestial bodies at the same time, and it will be the most powerful spectral survey telescope in the world. It will exert its power in the large-scale structure of galaxies, quasars and the universe, and uncover the mysteries of the structure of stars, star families and galaxies.
