The core collapse supernova phenomenon is dominated by neutrinos. This may seem surprising given the notoriously feeble interactions of these particles. But in the core collapse environment neutrinos can more than make up for their weak interactions with huge numbers. Recent experiments and observations have revealed much about these particles. We now know that neutrinos have small rest masses and that they can transform their flavors. For example, a neutrino emitted in the electron flavor could change into a neutrino of mu or tau flavor. This process could have significant implications for how supernovae explode, models of neutrino-affected nucleosynthesis, and the expected neutrino signal from a core collapse event. Recent simulations have solved a long-standing problem in following neutrino flavor transformation in the supernova environment. The results are startling and unexpected. Ultimately, these results may suggest how to use observations of supernova neutrinos to glean insight into neutrino properties that are currently unmeasurable in the lab, e.g., the neutrino mass hierarchy, and to get at heretofore mysterious astrophysical issues, e.g., supernova shock propagation.
