The said particle fell towards Earth back in December 2016, making its way from space almost the speed of light. As the high-energy particle flew into Earth, it hit an electron buried inside an ice sheet at Antarctica, thus producing a particle that decayed into a host of secondary particles. Particle recorded by the IceCube Neutrino Observatory The particles were picked up by the IceCube Neutrino Observatory, a unique massive telescope buried underneath the Antarctic surface.
