In 2022, the IceCube Neutrino Observatory at the South Pole announced evidence for high-energy neutrinos spewing from the “nearby” active galaxy NGC 1068. One of the brightest X-ray sources in the universe, NGC 1068 is an active galactic nucleus (AGN) with a central, supermassive black hole that actively gobbles up surrounding matter. X-rays shine brightly […]
“Project Hercules” is the latest educational video game from Field Day, an award-winning game design studio based at the Wisconsin Center for Education Research within the School of Education at the University of Wisconsin–Madison. Developed in collaboration with the Wisconsin IceCube Particle Astrophysics Center (WIPAC), the Wisconsin Department of Public Instruction, and a network of […]
The sun is up, but it’s still quite low on the horizon. When you face the sun, as in the image above looking at the South Pole Telescope, all of the surroundings are still dark and in shadow. Face away, as in the image below of the IceCube Upgrade drill camp, and all is clear […]
We would like to congratulate the following PhD graduates who successfully defended their theses in the summer of 2025: Kathrine Mørch Groth David Guevel Christoph Günther Yarno Merckx Julian Saffer Shefali Shefali Jessie Thwaites […]
Antarctica has sometimes been referred to as the end of the world. But for those who live at the South Pole, there’s a specific place known as the “End of the World.” It’s what they call the area past the storage berms out on the ice. Snow removed from around buildings is often dumped there […]
Introduction This data release accompanies IceCube’s recent search for high-energy neutrinos from the Sun with 10 years of IceCube and DeepCore data. This analysis set world-leading limits on dark matter scattering and solar atmospheric neutrinos. For further details, refer to the IceCube publication:“Search for high-energy neutrinos from the Sun using ten years of IceCube data,” […]
Yes, the sun has officially risen at the Pole. But it happened at the very end of the week, so we may have to wait a bit for an actual sunrise photo (or go back one or two weeks for something close). Last week was busy with several sunrise-related activities. IceCube’s winterovers were out cleaning […]
A total lunar eclipse started off last week at the Pole. IceCube winterover Ilya had set up a camera box in advance to capture photos during the event. Unfortunately, the weather was poor and the blood moon was not very visible, plus the outdoor camera setup wasn’t a match for the weather conditions. Still, Ilya […]
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 […]
