The Full Story

The Sudbury Neutrino Observatory, or SNO, is located in a mine near Sudbury, Ontario, Canada, about 2 kilometers underground. The deep underground location reduces background noise from cosmic rays and other particles. SNO played a crucial role in solving the solar neutrino problem by showing that neutrinos change flavor. That result won the 2015 Nobel Prize in Physics for Arthur B. McDonald.
