More than 20 IceCube institutions hosted 200 students in Belgium, Canada, Denmark, Germany, and the United States for the thirteenth edition of the IceCube Masterclass. Held between the months of March and May this year, the host institutions provided a day full of hands-on activities, webcasts, and lectures to local high school students. Since 2014, […]

WIPAC news that we’re hiding.
Prof. Francis Halzen honored with the 2026 APS Medal
Beneath 1.5 kilometers of ice near the geographic South Pole, the IceCube Neutrino Observatory is on the hunt for ghost particles.
As the world’s first gigaton neutrino detector, IceCube is used by astrophysicists to better understand cosmic objects by observing the neutrinos — abundant, nearly massless, and mysterious elementary particles — that they produce. […]
IceCube search for a correlation between galaxies and neutrinos
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. So far, high-energy neutrino emission has been […]
Exploring the universe through a new astrophysics video game
“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 […]
Students reach for the cosmos in IceCube Cosmic-Ray Summer Program
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 […]
Another successful field season for IceCube Upgrade at the South Pole
Since November of last year, a team of IceCube engineers and scientists have been hard at work during the second of three consecutive field seasons for the IceCube Upgrade. Over the course of the season, 37 team members, including 27 drill engineers and 10 installation and operations experts, were deployed to the U.S. National Science […]
IceCube observation of the cosmic-ray anisotropy in the Southern Hemisphere
Extremely energetic charged particles called cosmic rays are accelerated by violent cosmic objects before raining down on Earth from all directions. Protons and heavier nuclei make up these cosmic rays, which can then collide with other particles in the atmosphere to produce secondary particles that cascade into so-called “air showers.” For more than a century, […]
WIPAC agreement with Thai partners signals enthusiasm for future collaborations
This story was originally published by the University of Wisconsin–Madison International Division. Among the University of Wisconsin–Madison’s many ambitious research endeavors, the IceCube Neutrino Observatory stands out as one of the most unique. This remarkable telescope, which has instrumented a billion tons of South Pole ice, is designed to search for tiny, ghostlike particles called neutrinos, helping […]
Jim Madsen retires after 25 years with neutrinos
Jim Madsen, interim director of the Wisconsin IceCube Particle Astrophysics Center (WIPAC) at the University of Wisconsin–Madison and associate director for education and outreach for the IceCube Neutrino Observatory, recently announced that he was retiring after 25 years with IceCube and its predecessor AMANDA. His last day in the office was August 2. “With a […]
Carlos Argüelles-Delgado named a CIFAR Azrieli Global Scholar
This year, IceCube collaborator and Harvard University physics professor Carlos Argüelles-Delgado is among 10 emerging research leaders selected for the 2024-2026 cohort of the Canadian Institute for Advanced Research (CIFAR) Azrieli Global Scholars program, generously supported by the Azrieli Foundation. This ambitious next-generation initiative provides two years of unrestricted funding to talented researchers tackling important and […]
