For just the second time in human history, researchers have identified a source of high-energy neutrinos — ghostly subatomic particles produced in some of the universe’s most extreme environments. The discovery was made by an international collaboration led by Michigan State University and Technical University of Munich researchers at the IceCube Neutrino Observatory in Antarctica. The team announced its findings on Nov. 3 in an online webinar and will publish its study Nov. 4 in the journal

On December 6, 2016, a high-energy particle was hurtling through space at nearly the speed of light and happened to smash into an electron deep inside the South Pole’s glacial ice. The collision created a new particle, known as the W– boson. This enabled IceCube to make the first ever detection of a Glashow resonance event, a phenomenon predicted 60 years ago by Nobel laureate physicist Sheldon Glashow. The international IceCube Collaboration, including MSU scientists Claudio Kopper and Nathan Whitehorn, published this result online on March 11 in the journal Nature.
