At extremely high energies, the Universe is no longer transparent to photons, but it is to neutrinos. The IceCube Neutrino Observatory has transformed a cubic kilometer of natural Antarctic ice into a giant neutrino detector. Amongst a background of more than a million atmospheric neutrinos, IceCube discovered a cosmic neutrino flux with an energy range of 1 to 10,000 TeV. More recently, we reported the observation of 80 neutrinos from the nearby galaxy M77, 50 million light years away. And closer to home, we have seen our Milky Way in neutrinos.
I will report on recent results in the deep ice at the South Pole and provide an outlook on our future plans. I will also report on an upgrade currently under construction with a plan for completion in the 2025/26 South Pole summer. It will allow us to measure neutrino properties with unprecedented precision. It can also be used to look for transient astrophysical neutrino signals.
