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. […]
There was plenty of action this week at the Pole, indoors and out. Inside there was crocheting and a 5K race. Outside the auroras continued, bigger and brighter than ever. […]
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). […]
The aurora season is in full swing at the South Pole, as exemplified by this photo taken of the ARO (Atmospheric Research Observatory) building, bathed in a green glow. ARO is an NSF facility that supports long-term climate research programs. The building is located about 500 m from the main station and, like other outlying buildings, has no running water or sewage system. Hmm, guess you’re not making ice cream out there. But, back at the station, it looks like the IceCube winterovers’ foray into ice cream making continues—flavor of the week: Aurora Green Tea with Fresh Lavender. […]
What’s this? Almost looks like a sample from the sushi plate (yep, we’ve already confirmed they eat well at the Pole) fell off outside and rolled around in the snow. But no, it’s yukimarimo. You heard right—a real word for a real thing—tiny, lightweight tumbleweeds of the Antarctic. […]
The Wisconsin IceCube Particle Astrophysics Center (WIPAC) is pleased to host the international IceCube Collaboration for the annual spring meeting May 07-11, 2013. […]
The auroras were busy this week, curling themselves up to look like cinnamon rolls. The IceCube winterovers were busy as well with several videoconferences, some with schools in the US and one with The Mind Museum in Manila. The photo below shows Blaise and Felipe (left to right) posing recently at the geographic South Pole (no, the pole marker is not bent, it’s just a wide-angle shot). There’s also a great shot of some sastrugi (we’ve learned about them before) pointing their way to the moon. Finally, check out this short time lapse video of an aurora unfolding above the moon—next best thing to being there. […]
Here they come. The auroras, that is. Although the sky is still allowing the sun’s presence to be somewhat felt from just below the horizon, it is also giving the winterovers their first glimpses of these special treats—from faint, wisping hints to full-on sprays of color. […]
This week had all the usual stuff—you know, calibrations, detector statistics, data handling, that kind of stuff. But it also had … Yuri’s Night. This is a global celebration held each April 12th to commemorate Yuri Gagarin, first man in space and an inspiration to many of the adventurous sort. The whole station observed the occasion with music and costumes. […]
In a paper submitted to Physical Review Letters, the IceCube Collaboration confirms highest energy neutrinos ever observed. […]
