MAGIC Telescopes Trace Origin of Rare Cosmic Neutrino


For the first time, astrophysicists have localised the source of a cosmic neutrino originated outside of the Milky Way. With high probability, the neutrino comes from a blazar, an active black hole at the centre of a distant galaxy in the Orion constellation. The scientists reached this interesting finding by combining a neutrino signal from IceCube with measurements from the Fermi-LAT and MAGIC telescopes as well as other instruments. This multi-messenger observation could also provide a clue to an unsolved mystery: the origin of cosmic rays.
