Xining : China on Saturday launched the construction of a new large astronomical observation project, the Xue-shan-mu-chang 15-meter SubMillimeter Telescope (XSMT).
Situated on the Qinghai-Tibet Plateau, this project aims to enhance the country’s capabilities in exploring the cold, hidden universe by establishing a high-precision facility that addresses a notable gap in its existing astronomical infrastructure.
With a diameter of 15 meters, the telescope will be located in the city of Delingha, northwest China’s Qinghai Province, at an altitude of 4,800 meters. Led by the Nanjing-based Purple Mountain Observatory under the Chinese Academy of Sciences, the project is scheduled to be completed in 2027.
