The Large High Altitude Air Shower Observatory (LHAASO) is the world's highest, largest and most sensitive cosmic ray detection device.

The core scientific objectives of the High Altitude Cosmic Ray Observatory are to explore the origin of high-energy cosmic rays and the associated cosmic evolution and activity of high-energy celestial bodies, and to search for dark matter, and to search extensively for gamma-ray sources in the universe, especially in the Milky Way, to accurately measure them from less than 1 TeV (1 trillion electron volts, also known as "teren volts") to more than 1 PeV (1000 trillion electron volts, also known as "patnapolen volts") Measure the composition and energy spectrum of higher energy diffuse cosmic rays, reveal the laws of cosmic ray acceleration and propagation, and explore new physical frontiers.
