The field of multi-messenger astrophysics is being born. The IceCube Neutrino Observatory at the South Pole plays a role by detecting neutrinos and cosmic rays produced in the most extreme environments in the universe. We aim to understand these environments by studying different kinds of radiation emitted by them. IceCube has measured a flux of neutrinos of astrophysical origin, although their sources remain unidentified. We also study the flux of cosmic rays, its composition and its arrival directions. We will briefly review the main results of IceCube and how they fit in the bigger picture. We will also discuss what the future holds for the detection of neutrinos and cosmic rays at the South Pole. To identify sources of astrophysical neutrinos, the detection of transient phenomena in coincidence with other instruments looks promising. Within this context, it is crucial to have detectors with large aperture, large duty cycle and good angular resolution.
