A massive underground neutrino detector in southern China, JUNO, nears completion. Set to operate next year, this $300 million project aims to detect antineutrinos from nearby nuclear reactors, shedding light on neutrino properties and potentially unlocking secrets of the universe’s origins. JUNO joins other global neutrino projects in this quest. A massive underground neutrino detector in southern China, JUNO, nears completion.
