The Super-Kamiokande, or Super- K as it’s known, is not the latest nightclub VIP booth but is, rather, a neutrino observatory designed to search for proton decay, study solar and atmospheric neutrinos, and keep watch for supernovas in the Milky Way. Located 1000m underground in the Mozumi Mine in Hida city, Gifu, Japan, it consists of 50,000 tons of pure water surrounded by about 11,200 photomultiplier tubes. The cylindrical structure is 41.4m tall and 39.3m across. In the image above, the water has yet to be returned after a reconstruction and thus the jewel is revealed.
