Sudbury Neutrino Observatory PhotoThe Sudbury Neutrino Observatory in Ontario, Canada is a 12-m sphere buried 2.1 Km below the ground in an old mine shaft. It is filled with heavy water, which consists of oxygen and deuterium, an isotope of hydrogen with one neutron, and is surrounded by 9600 photomultiplier tubes to detect light produced as a result of collisions by neutrinos.
