As cosmic rays collide with particles in the Earth’s atmosphere, air showers containing atmospheric muons and neutrinos are produced. The atmospheric neutrinos are then detected by DeepCore, a denser and smaller array of sensors in the center of the IceCube Neutrino Observatory at the South Pole. Compared to the main IceCube detector, DeepCore is sensitive […]
As the sky at the South Pole gets brighter, we can definitely see the difference from just two weeks ago in this view of the IceCube Lab. The snow drift is still there, though, and that will stay there until it is intentionally moved—the sun won’t be able to make a dent in it, even […]
The sky at the South Pole continues to brighten up before official sunrise—lately to the point where headlamps are no longer needed to see while walking outside. The moon can help brighten things up even more on some days. IceCube winterover Ilya was out with his camera last week, taking some nice photos of the […]
The IceCube Neutrino Observatory, embedded in a cubic kilometer of Antarctic ice, searches for weakly interacting particles called neutrinos that are able to travel undisturbed through the cosmos. Of interest are high-energy astrophysical neutrinos that can arise from cosmic ray interactions with matter or photons in astrophysical sources. Thus far, the dominant sources of the […]
Everything’s blue and rather dark, but not gloomy. There’s just a hint of orange starting to spread along the horizon, brightening up the scenery. Last week at the Pole, IceCube’s winterovers had some minor detector issues to respond to, but they otherwise enjoyed a rather quiet week. That’s the benefit of a well-behaved detector—more quiet […]
This could the season’s last view of the IceCube Lab with the Milky Way visible overhead. Key word being could—guess we’ll see. The Milky Way also appears, somewhat more faintly, below as it stretches upward from the IceCube Upgrade drill camp. Last week at the Pole was rather quiet in most respects. The kitchen, however, […]
When high-energy particles called cosmic rays collide with Earth’s atmosphere, they create cascades of particles or air showers that emit faint radio signals. Because they are so faint, they are often drowned out by background signals from natural sources (the universe) and man-made sources (radio transmitters), making it difficult to discern signals originating from a […]
It seems so bright outside at the Pole—but we didn’t miss the sunrise, that’s still to come. However, you can see the beginning of some light along the horizon as twilight progresses. They are about to enter nautical twilight, which is basically the middle stage between night and day. Last week, there was also the […]
Over six weeks in June and July, 15 undergraduate and early graduate students from IceCube institutions, along with four visiting students, including an REU student, participated in the Cosmic-Ray Summer Program hosted this year at the University of Wisconsin–Madison (UW–Madison). The students gained hands-on research experience, attended lectures by IceCube scientists, learned software tools and […]
Quiet time at the South Pole is good for any number of things—last week it was getting all the board games sorted and organized in the game room. Board games have proven to be a popular past time at the Pole. IceCube winterover Ilya was also out on the ice removing the covers on the […]
