The Large High Altitude Air Shower Observatory (LHAASO) is a gamma-ray and cosmic-ray observatory in Daocheng, in the Garzê Tibetan Autonomous Prefecture in Sichuan, China.
It has three underground observing pools, each “more than triple the size of the Water Cube (National Aquatic Center) in Beijing”.
Research teams from Australia and Thailand will participate in the project directly, with others expressing interest.
[4] The observatory works essentially as the CASA-MIA observatory did but with a bigger surface array, better muon detectors, improved designed layout and at higher altitude.
[6][7] On 26 February, 2024, LHAASO reported the discovery of "a giant ultra-high-energy gamma-ray bubble structure in the Cygnus star-forming region."
