Caption: Sudbury Neutrino Observatory (SNO). Situated in a cavern 2 km underground in a nickel mine near Sudbury, Ontario, SNO is a 12 m diameter acrylic sphere filled with heavy water. The sphere is enclosed in the 18 m diameter geodesic structure seen here, which supports 10, 000 photomultiplier tubes that detect faint Cerenkov light emitted by charged particles produced when neutrinos interact in the heavy water. SNO records neutrinos coming from cosmic ray collisions in earth's atmosphere, from the sun, or from other astronomical sources such as supernova explosions.
