IceCube's discovery of cosmic neutrinos offers a new view of our Universe and already provides new insights into the extreme universe. I will present the most recent results from IceCube Neutrino Observatory and review the status of the search for the sources of cosmic neutrinos. I will emphasize the search via multimessenger paradigm connecting neutrinos, gamma ray, and cosmic ray observation. I will discuss the prospects for observation of individual point sources and describe our efforts to identify the Galactic sources of cosmic neutrinos.
