The observations at the Sudbury Neutrino Observatory showed that the "missing neutrinos" had changed into a different type, specifically from electron neutrinos to other types of neutrinos. This solved the solar neutrino problem by reconciling the discrepancy between the predicted number of neutrinos produced by the Sun and the number detected on Earth by other experiments.
