The construction of China's large scientific facility — the Jiangmen Underground Neutrino Experiment, has entered its final stage. It is expected that all installation will be finished by the end of this month.

Located 700 meters underground in Jiangmen, Guangdong province, a nearly 12-story-tall acrylic sphere is placed at the center of a 44-meter-deep water pool. This largest acrylic vessel in the world contains 20,000 tons of transparent liquid, which will play a crucial role in detecting neutrinos and exploring the origins of the universe.

"The primary scientific goal of the Jiangmen Underground Neutrino Observatory is to measure the neutrino mass hierarchy and oscillation parameters, which will play a crucial role in testing supernova explosion mechanisms, exploring the origins and evolution of the universe, and discovering new physical phenomena," said Wang Yifang, former director of the Institute of High Energy Physics at the Chinese Academy of Sciences.
