Large High Altitude Air Shower Observatory
Large High Altitude Air Shower Observatory, Cosmic-ray observatory in Sichuan Province, China
The Large High Altitude Air Shower Observatory contains multiple detectors spread across 1.3 square kilometers at 4410 meters above sea level.
Chinese Academy of Sciences initiated the construction of LHAASO in 2017 to advance research in gamma-ray astronomy and cosmic ray physics.
Scientists from multiple Chinese research institutes collaborate at LHAASO to study the origins of cosmic rays and galactic phenomena.
The facility maintains continuous monitoring of cosmic rays through an array of water Cherenkov detectors and electromagnetic particle detectors.
LHAASO detected ultra-high-energy gamma rays from the Crab Nebula, reaching unprecedented energy levels of 1.4 PeV.
