The previous week’s feature image showed the South Pole Telescope with the moon setting behind it. Here we see it again, but set against an aurora backdrop while its dish is scanning the sky for CMB (cosmic microwave background) mapping. […]
Introduction Results from the IceCube Neutrino Observatory have recently provided compelling evidence for the existence of a high energy astrophysical neutrino flux utilizing a dominantly Southern Hemisphere data set consisting primarily of νe and ντ charged-current and neutral-current (cascade) neutrino interactions. In the analysis presented here, a data sample of approximately 35000 muon neutrinos from […]
This album has been created to be distributed with the press release announcing the publication in PRL of a paper by the IceCube Collaboration about the confirmation of the astrophysical nature of high-energy neutrinos with an independent search in the Northern Hemisphere. Press release link. […]
Today, the IceCube Collaboration announces a new observation of high-energy neutrinos that originated beyond our solar system. This study, which looked for neutrinos coming from the Northern Hemisphere, confirms their cosmic origin as well as the presence of extragalactic neutrinos and the intensity of the neutrino rate. The first evidence for astrophysical neutrinos was announced by the collaboration in November 2013. The results published now in ”Physical Review Letters” are the first independent confirmation of this discovery. […]
It’s still dark at the South Pole, with sunrise not for a while yet. So don’t be confused—that was the moon, not the sun, setting behind the South Pole Telescope. Once it had set, some bright and lively green auroras took over the sky. […]
Last week at the Pole they had Christmas in July. Since the seasons in the Southern Hemisphere are the reverse of the Northern Hemisphere, many southern locales celebrate in July or August so that they can have a wintry feel to their festivities. The South Pole station had a tree, presents, and plenty of sweets on hand for theirs. […]
The IceCube Collaboration has a strong presence at the 34th International Cosmic Ray Conference (ICRC 2015) with over 50 presentations and posters. ICRC started on July 30 and runs through August 6 in The Hague, Netherlands. […]
The Astrophysical Multimessenger Observatory Network (AMON) will link existing and future high-energy astrophysical observatories into a single virtual system, enabling near real-time coincidence searches for multimessenger astrophysical transients and their electromagnetic counterparts and providing alerts to follow-up observatories. […]
You might not know you’re at the South Pole from the photo of this watermelon. But there it is, growing in the greenhouse at the station, only a little bigger than a tennis ball at the moment. With it’s supportive, handmade hammock, hopefully it will reach a nice size and ripeness for the crew to enjoy. […]
It’s dark at the Pole, and even a headlamp’s light only goes so far. Paths to outlying buildings are lined with flags before winter arrives, when there’s still sufficient light for the installation. On a moonless winter night, though, there’s no question that the flag line has a value much greater than the sum of its parts. It’s a real lifesaver. […]
