This Giant Subterranean Neutrino Detector Is Taking On the Mysteries of Physics
Located in China, Juno is a 17-country collaboration that will try to detect neutrinos and antineutrinos to learn more about their mass.
This is Juno, the Jiangmen Underground Neutrino Observatory, a new, large-scale experiment studying some of the most mysterious and elusive particles known to science. They are fundamental particles, meaning they don’t break down into smaller constituent parts, which makes them very small and very light. Surrounding the liquid is a massive stainless steel lattice that supports a vast array of highly sensitive light sensors, called photomultiplier tubes, capable of detecting even a single photon produced by an interaction between a neutrino and the liquid, and converting it into a measurable electrical signal.
