IceCube has helped unravel one of the oldest riddles in physics and astronomy – the origin of high-energy neutrinos and cosmic rays
For the first time ever, high-energy cosmic neutrinos have been detected coming from an energetic galaxy known as a blazar
Failing to detect the elusive particle means we remain in the dark about the origin of why neutrinos have mass
