The Universe has been explored using visible light since the dawn of astronomy. I will report about a new type of astronomy with the IceCube Neutrino Observatory at the South Pole. IceCube has transformed a cubic kilometer of natural Antarctic ice into a giant neutrino detector. At extremely high energies the Universe is no longer transparent to photons but it is to neutrinos - and there are many of them. This allows for a unique new way of astronomy. IceCube has seen 80 neutrinos from the nearby galaxy M77, some 50 million light years away. Most recently, closer to home, we have seen our own Milky Way in neutrinos. I will report about recent results, opportunities for Multi Messenger Astrophysics and future plans.
