Neutrinos are particles produced in some nuclear processes.  The sun produces them as it burns hydrogen into helium.  In the 1960s, Ray Davis and John Bahcall set out to measure them.  In a tank of drycleaner deep within South Dakota's Homestake Mine, Davis measured one-third the amount of neutrinos that were predicted by Bahcall's calculations.  This discrepancy was dubbed "The Solar Neutrino Problem."  Subsequent experiments in Japan, the Soviet Union, and Italy confirmed the problem.  Many solutions were proposed, including the eventual solution: neutrino oscillations.  In 2001, the Sudbury Neutrino Observatory (SNO) in Sudbury, Ontario, Canada, published the results that confirmed neutrino oscillations and solved the problem, leading to Nobel Prizes for Davis in 2002 and others for neutrino oscillations in 2015.h.
