Glossary term: neutrino
Description: Neutrinos are subatomic particles produced by various physical processes. In the core of the Sun, neutrinos are a product of nuclear fusion. Nuclear reactions and high energy densitites in supernova explosions also produce bursts of neutrinos. Observing neutrinos is difficult as they interact very weakly with atoms. Typically neutinos are detected by observing huge tanks of water (or blocks of ice such as at the IceCube Neutrino Obseravatory at the South Pole). When a neutrino hits a water molecule in one of these tanks (or in the block of ice), it sets off particle reactions that lead to tiny amounts of light being produced. This light can be detected and analysed. Neutrinos have been detected from the nuclear reactions in the core of the Sun and from supernovae.Related Terms:
