Lhasa to build the world's largest refracting optical telescope

According to the Department of science and technology of Tibet Autonomous Region, the project of "construction of one meter optical astronomical telescope with dual functions of scientific research and popular science in high altitude areas" jointly declared by the National Astronomical Observatory of the Chinese Academy of Sciences and the Tibet Museum of natural sciences has officially started a few days ago, which means that the world's largest refracting optical telescope will land in Lhasa.
Wang Junjie, deputy director of the science and Technology Department of the Tibet Autonomous Region, said that the one meter optical telescope will be independently developed and built by Chinese scientists. After completion, with Tibet's high altitude and good observation conditions, it will be able to carry out a number of scientific research and observation work, such as poor photometry of variable stars, binary stars and other celestial bodies, monitoring of near Earth Asteroids and space targets. At the same time, it will also provide in-depth services for popular science education in Tibet.
The project is a national key R & D project jointly declared by the National Observatory of the Chinese Academy of Sciences, Tibet Museum of natural sciences, Changchun Institute of optics, precision machinery and physics of the Chinese Academy of Sciences, Zijinshan Observatory of the Chinese Academy of Sciences and Fujian Fuguang Co., Ltd., which has been approved and signed a joint implementation agreement, It aims to build Tibet's first meter level scientific research and popular science dual-purpose telescope with the capabilities of scientific observation, astronomical photography, online live broadcast and distance teaching, so as to provide in-depth services for popular science education and scientific research.

In order to further improve the functional status of the Tibet Natural Science Museum, it was also decided to build the world's highest planetarium. After the completion of the development of the one meter optical telescope carried by the proposed Tibet Observatory, it will be the largest refracting optical telescope in the world.
At present, the construction project of Tibet planetarium has completed the preliminary procedures for approval, and it is planned to officially start construction within this year.
It is understood that the first autonomous regional (provincial) planetarium will be built in Tibet in the next step. The one meter optical telescope will be installed on the planetarium to further improve Tibet's popular science resources. The Tibet planetarium is expected to start construction within this year and will become the highest planetarium in the world.
The latest announcement of China is not only the ground refracting optical telescope, but also the space Survey Telescope.
During the two sessions, Zhou Jianping, member of the National Committee of the Chinese people's Political Consultative Conference and chief designer of China's manned space project, told CCTV national defense and military channel that after the completion of China's space station, a space Survey Telescope will be launched.
The aperture of the telescope will reach two meters, the resolution is the same as that of the Hubble Space Telescope, and the field of view angle is more than 300 times larger than that of the Hubble Space Telescope, which can be upgraded in orbit.
Chief designer Zhou Jianping also revealed that the telescope's purpose is to explore the origin and evolution of the universe, black holes, dark matter and dark energy and other cutting-edge issues
