SNO (Sudbury Neutrino Observatory)

The Sudbury Neutrino Observatory (SNO) is a research facility in Ontario, Canada, designed to study neutrinos—tiny, nearly massless particles that are produced in nuclear reactions, such as those happening in the sun. By using a large tank of heavy water, SNO captured neutrinos and analyzed their interactions. This groundbreaking work helped confirm that neutrinos have mass and provided insights into how the sun produces energy. SNO's findings contributed significantly to our understanding of particle physics and the fundamental processes powering the universe, earning recognition in the scientific community.
