The IceCube Neutrino Observatory, located at the geographic South Pole, is a Cherenkov detector that continuously monitors a cubic kilometer of instrumented glacial ice for neutrino interactions in the sub-TeV to EeV energy range. Its primary design goal is the study of powerful astrophysical objects that could act as natural particle accelerators and thus as sources of (ultra) high energy cosmic rays - in short: to do neutrino astronomy. IceCube has discovered a diffuse flux of high energy astrophysical neutrinos consistent with an extra-galactic origin. In addition the IceCube Collaboration recently obtained evidence for neutrino emission from the direction of the blazar TXS 0506+056, making it the first potentially identified source of high energy cosmic rays. IceCube also contributes to fundamental particle physics through the study of neutrino interactions at large energies. In this talk I present recent results and measurements of high energy neutrinos with IceCube.
