IceCube neutrinos give us the first image of the depths of an active galaxy. They allow us to get a little closer to the answer to the eternal question of the origin of cosmic rays . For the first time, an international team of scientists - including the IIIHE, Faculty of Science - has found evidence of high-energy neutrino emission in the galaxy NGC 1068. Also known as Messier 77, it is one of the best known and studied galaxies to date, active in the constellation Cetus. First identified in 1780, this galaxy, located 47 million light years away, can be observed with large binoculars. The detection was made by the National Science Foundation-supported IceCube Neutrino Observatory, a giant neutrino telescope consisting of a billion tons of instrumented ice at depths of 1.5 to 2.5 kilometers below the surface of Antarctica near the South Pole. With the neutrino measurements of NGC 1068, IceCube is one step closer to answering the age-old question of the origin of cosmic rays.
