Huge neutrino detector sees first hints of particles from exploding stars

Japan’s Super-Kamiokande observatory is seeing what might be the first hints of neutrinos from exploding stars. Neutrinos are subatomic particles that can come from various cosmic sources; those from inside supernovas could provide information about potentially new physics occurring under extreme conditions. Although the data from Super-K are still too weak to claim a definitive discovery, researchers hope to eventually prove that neutrinos are so stable that those from ancient supernovas are still around.
