Week 22 at the Pole

A green sky flecked with swirling patterns of white lines. That’s what you get from sixty 30-second exposures taken through a ceiling dome at the South Pole station and made into a composite image. The IceCube winterovers have been capturing some amazing photos at the South Pole. […]

Week 21 at the Pole

Antarctica is often described as the coldest, driest, and windiest place on earth. Cold and dry might be hard to discern from photos, but windy? These flags give it away—here, they’re taking a real beating. The group photo below (also with flags flapping away) was orchestrated to commemorate the invention of the Ethernet 40 years ago (they’re posing with a long Ethernet cable held between themselves). The photo garnered a response from the inventor himself, Bob Metcalfe, then at Xerox PARC. […]

The cosmic-ray Moon shadow seen by IceCube

A recent measurement of the Moon shadow in TeV cosmic rays with the IceCube telescope sets an upper limit on the detector’s absolute pointing accuracy to 0.2 degrees. The IceCube Collaboration presents these results in a paper submitted today to Physical Review D. […]

First observation of high-energy neutrino oscillations by DeepCore and IceCube

The IceCube Neutrino Observatory, which comprises the IceCube and DeepCore detectors, has been designed to contribute heavily to our understanding of neutrino physics. In a paper submitted today to Physical Review Letters, the IceCube Collaboration has announced the first statistically significant detection of neutrino oscillations in the high-energy region (20–100 GeV).
