BEIJING, 12 May (BelTA - Xinhua). - Lenghu, on the north side of China's Qinghai-Tibet Plateau, enjoys the advantages of clear night skies, stable atmospheric conditions, and a dry climate, making it one of the world's best astronomical observatory sites.
Construction of the Lenghu site started in 2018. Upon its completion, it will house at least nine optical astronomical telescope projects including some 30 telescopes, with an investment of nearly 2 billion yuan (about 289 million U.S. dollars).
Among these newly-built projects, a new solar observation facility started a test run recently. The Accurate Infrared Magnetic Field Measurements of the Sun (AIMS) is the first solar magnetic-field telescope working in the mid-infrared wavelength in the world.
