Improved IceCube Upgrade optical module paves the way for IceCube-Gen2

The IceCube Neutrino Observatory, a cubic-kilometer-sized neutrino telescope, searches for high-energy neutrinos of astrophysical origin. Located at the geographic South Pole, IceCube consists of 5,160 digital optical modules (DOMs) across 86 vertical cables (strings) embedded deep within the Antarctic ice, as well as a surface array, IceTop, and a denser inner subdetector, DeepCore. When neutrinos […]

Week 1 at the Pole

At the South Pole, they have their traditions…and their training. Last week, training included station-wide emergency response drills. And training can involve some fun. Lobbing balls around in the gym (or doing anything), though, in full firefighting gear is strenuous and thus good practice. PolarTREC educator Elaine Krebs arrived at the Pole as part of […]

IceCube reports first detection of candidate astrophysical tau neutrinos

The IceCube Collaboration has reported two candidate events for the final unobserved Standard Model cosmic messenger: astrophysical tau neutrinos. And one of these neutrino events, as with previous prominent particles detected by the IceCube Neutrino Observatory, has been given its own nickname.  Double Double, an event with a high probability of being produced by a […]

Week 52 at the Pole

Week 52—the last of 2022—was a busy week at the South Pole. Some of IceCube’s summer staff were leaving by the end of the week, so there were some minor items to finish up before then. Also, the second South Pole overland traverse (SPOT2) arrived, with more fuel for the station and some IceCube Upgrade […]

Week 51 at the Pole

There was lots of activity at the Pole last week. Some IceCube summer crew members are now there working alongside the winterovers. The early part of the week was dedicated to hardware repairs and upgrades at the IceCube Lab. They also packed up cargo, including hard drives destined for long-term storage in Madison, which they […]

Download IceCube’s 2023 calendar!

It’s almost the new year, which means it’s time for the 2023 IceCube Calendar! Featuring breathtaking photos taken by our winterovers from the past few years, this calendar will teach you something new about the IceCube Neutrino Observatory and the South Pole every month. The calendar is available to download in three different sizes in either […]

Week 50 at the Pole

Ahh, summer! Sunshine and warm lazy days. At the South Pole, though, you only get the sunshine (unless it’s cloudy), but not the warmth. Summer at the Pole also means more people coming to the station. Among the group arriving in the photo above are three members of the IceCube team. They received a special […]

IceCube’s latest search for neutrinos from fast radio bursts using cascades

The IceCube Neutrino Observatory, a one-of-a-kind detector operating at the Amundsen-Scott South Pole Station, searches for neutrinos—tiny, ghost-like particles that can travel extremely long distances unperturbed. Of particular interest to IceCube are astrophysical neutrinos, high-energy neutrinos originating from beyond our galaxy. Because they can travel straight distances, they can be traced back to their sources. […]
