The IceCube Neutrino Observatory gets a major upgrade beneath the ice
In 2019, the U.S. National Science Foundation, together with US institutional and international partners, approved funding of the IceCube Upgrade project, an improvement that would significantly push the scientific capabilities of the IceCube Neutrino Observatory. Seven years later, the IceCube Upgrade has now been successfully deployed, marking the first significant…
Upgrade Update #15
This is the final Upgrade Update as the last field work tasks have been completed and all the Upgrade personnel have left or are scheduled to leave the South Pole. Clear skies and sunshine show off the organized lineup of Upgrade drill towers and other structures that have been moved…
Week 10 at the Pole
Look at that sky! It may be bright and sunny, but those lengthening shadows foretell what’s to come. Darkness will fall in a few short weeks—in preparation, the winterovers were out setting up the flag lines leading to the Dark Sector buildings, including the IceCube Lab. When it’s dark or…

Real-time Alerts
IceCube is a unique telescope that offers an uninterrupted view of almost the full sky and is capable of detecting neutrinos at the highest energies while still being sensitive to much lower energy neutrinos. The dynamic range of the instrument is from GeV to hundreds of TeV and above, with the observation of cosmic neutrinos at energies approaching 10 PeV. Detection of MeV neutrinos is possible provided they are produced in bursts, as is the case for a Galactic supernova explosion.
IceCube real-time alerts trigger on a series of neutrino signatures with a high chance of identifying a neutrino of astrophysical origin, thus pointing to interesting regions of the sky, and notify the international community when an interesting cosmic phenomenon could be observed.
Outreach for people of all ages
IceCube has a long history of outreach activities that range from small group presentations to large collaborative art-science installations. Capitalizing on the appeal of the South Pole detector and building upon established collaborations, IceCube continues to find new ways to introduce IceCube science to an ever broader audience.
