IceCube
Other neutrino observatories rely on different designs, the most shocking of which might be the IceCube neutrino observatory at the South Pole. Despite its remote location, IceCube is basically a frozen Super-Kamiokande. It consists of 86 “strings” each containing 60 light-detecting modules, placed into holes drilled 4,500 to 8,000 feet into the ice. Neutrinos create tiny flashes in the rare event that they interact with the Antarctic ice beneath the experiment, which the detectors then sense. IceCube has already made incredible measurements of neutrinos from outer space; most recently, it found the origin of ultra high-energy cosmic rays striking Earth.
