Yunnan Astronomical Observatory

The Yunnan Astronomical Observatory is a research facility situated on Phoenix Hill at about 2000 meters elevation, equipped with modern telescopes and multiple observation stations. The site employs the Lijiang telescope, a vacuum solar telescope, and a large radio telescope for scientific investigations.

The facility was founded in 1930 when astronomers from Beijing and Purple Mountain Observatory fled here during the Japanese invasion, and it opened officially in 1938. This location became a refuge for astronomical science during a turbulent period in China.

The facility serves as a major center for astronomical education in southwestern China, where visitors discover the cosmos through exhibitions and public programs. It connects people with scientific learning and fosters curiosity about the stars and space.

Visiting requires good preparation because of the high elevation and the scientific nature of the location. It is wise to check ahead about opening hours and access to visitor areas, as not all research areas are open to the public.

Researchers at the site have developed specialized methods for studying binary star systems using advanced computational techniques. This focused work has brought the facility international recognition within the astronomy community.
