The Supernova Early Warning System (SNEWS) is a collaborative effort designed to detect and provide early warnings of potential supernova events in our galaxy. Supernovae are massive explosions that occur at the end of a star's life cycle, and they can produce a significant amount of neutrinos—subatomic particles that are produced in large numbers during such explosions. SNEWS operates by monitoring a network of neutrino detectors around the world.
