A scientist monitors an experiment in China Jinping Underground laboratory in southwest China's Sichuan Province, Oct. 26, 2022. The lab is located at 2,400 meters under the surface of Jinping Hydropower Station. It has a store of xenon, one of the few materials that interact with dark matter, and the cosmic rays that commonly interfere with attempts to observe dark matter generally cannot penetrate to such a depth underground. A series of dark matter detection experiments were conducted in the lab.
