Description
The Universe has been explored using visible light since the dawn of astronomy. 
I will report on 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 observed energetic neutrinos coming from a nearby galaxy, 50 million light years away. Most recently, close to home, we have seen our own Milky Way in neutrinos. I will report on the fascinating results collected in the deep ice at the South Pole, and about the incredible journey to do science at such an extreme location.
