This photo taken during a media tour on October 11, 2024 shows workers working on the stainless steel structure of the neutrino detector, a stainless steel and acrylic sphere around 35 metres in diameter, at the Jiangmen Underground Neutrino Observatory (Juno) in Kaiping, in southern China's Guangdong province. Far beneath the lush landscape of southern China, a sprawling subterranean laboratory aims to be the world's first to crack a deep scientific enigma. China's showpiece is the Jiangmen Underground Neutrino Observatory (Juno), a state-of-the-art facility for studying the minuscule subatomic particles.
