I will describe how photons can be complemented for the observation of the non-thermal universe by neutrinos and gravitational way.
IceCube, with its cubic-kilometric volume deep in the ice of the South Pole, is now monitoring the sky looking for neutrino flares of compact objects like pulsars and black holes.
I will present its recent results on cosmic exploration and on fundamental physics such as neutrino oscillations.
