NASA's Fermi Links Cosmic Neutrino to Monster Black Hole

The Ray Space Telescope identified a high-energy neutrino source from a blazar, a type of galaxy with a supermassive black hole. This neutrino, after traveling 3.7 billion years, was detected in Antarctic ice, producing a Muon tracked by the Ice Cube Neutrino Observatory. NASA's Fermi Gamma Ray Space Telescope confirmed the blazar as the source, marking the first time a neutrino was traced to a black hole. This discovery is a significant step in Multi-Messenger Astronomy, which combines light, gravitational waves, and neutrinos to study cosmic phenomena.
