H.E.S.S. collaboration detects the most energetic cosmic-ray electrons and positrons ever observed
www.eurekalert.org
Scientists from the CNRS, a consortium of German universities, and the Max-Planck-Institut für Kernphysik working at the H.E.S.S. observatory have recently identified electrons and positrons with the highest energies ever recorded on Earth. They provide evidence of cosmic processes emitting colossal amounts of energy, the origins of which are as yet unknown. These findings are due to be published on 18 November in the journal Physical Review Letters.

Original Title: Scientists detect the most powerful cosmic rays ever — and their unknown source could be close to Earth.This is an important result, as we can conclude that the measured CRe [cosmic ray electrons] most likely originate from very few sources in the vicinity of our own solar system.
