China's new underground lab prepares to study neutrinos by 2025

A new underground lab in China, the Jiangmen Underground Neutrino Observatory (JUNO), is set to begin operations in late 2025. It will study neutrinos, subatomic particles that could provide insights into the universe's early days. JUNO, located 700 meters underground, will analyze neutrinos from nearby nuclear power plants and the sun. This project follows years of construction and a $300 million investment, aiming to gather data for up to six years. The U.S. Deep Underground Neutrino Experiment (DUNE) will start later, around 2030, due to funding and construction delays. Despite political tensions, some U.S. scientists continue to collaborate on JUNO, focusing on scientific progress.
