            cubic kilometer of natural Antarctic ice into a neutrino
            detector. The instrument detects more than 100,000 neutrinos
            per year in the GeV to PeV energy range. Among those, we
            have isolated a flux of high-energy cosmic neutrinos. I will
            discuss the instrument, the analysis of the data, the
            significance of the discovery of cosmic neutrinos, and the
            recent multimessenger observation of a flaring TeV blazar in
            coincidence with the IceCube neutrino alert IC170922. The
            large cosmic neutrino flux observed implies that the
            Universe’s energy density in high-energy neutrinos is the
            same as that in gamma rays, suggesting that the sources are
            connected and that a multitude of astronomical objects await
            discovery.<o:p></o:p></span></p>
