Our Black Hole May be a Source of the Mysterious Neutrino Particle

Neutrinos are like the ghosts of the particle world, carrying no charge and interacting with electrons and protons in only the faintest ways. Now a new study suggests that the great majority of high-energy neutrinos that can be found in the Milky Way Galaxy may be coming from the large black hole at its center, implying that black holes are actually neutrino factories.
