China's Large High Altitude Air Shower Observatory (LHAASO), a high-altitude cosmic ray observatory, has passed national acceptance procedures on Wednesday, according to the Chinese Academy of Sciences (CAS).

LHAASO, covering an area of 1.36 square kilometers located 4,410 meters above sea level in Daocheng County, Tibetan Autonomous Prefecture of Garze, southwest China's Sichuan Province, is one of the country's key national science and technology facilities.

According to CAS, the observatory is designed to explore the mysteries of the universe by observing cosmic rays.

"Cosmic rays carry important scientific information about the origin of the universe, the evolution of celestial bodies and solar activity," said Cao Zhen, chief scientist at LHAASO and a researcher at the Institute of High Energy Physics under CAS.

It will also be used for exploring cosmic evolution and high-energy celestial activities, and conducting research on dark matter, according to CAS.

With the unique advantages of a high altitude and key core technologies, LHAASO is the most sensitive ultra-high-energy gamma ray detector installation in the world, according to CAS. 

The construction of the main part of the observatory began in 2017 and was completed in 2021. It has carried out international cooperation with 28 astrophysical research institutions on basic research in fields like cosmology, astronomy and particle physics, the CAS added.
