Neutrinos are very small particles that pass through matter almost untouched, so they carry information from far away in space. The source says the prize honours the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin. The piece is mainly an explainer, so the details of the discovery are limited here.
