In the wilderness of Daocheng, southwest China's Sichuan Province, 4,400 meters above sea level, Chinese scientists are constructing the Large High-Altitude Air Shower Observatory (LHAASO), a cosmic ray observation facility of the area equivalent to 200 football fields. Different detectors are being installed to form a huge "net" to catch the particles generated by cosmic rays in the atmosphere, to help scientists study both the micro and the macro worlds in the universe. Three huge underground pools, more than triple the size of the Water Cube (National Aquatic Center) in Beijing, will hold detectors to collect high-energy photons generated by remote celestial bodies. Surrounding the pools, 12 telescopes will be erected to conduct high-precision measurement of cosmic rays with the highest energy.
