Breakthrough in the search for cosmic particle accelerators

(Deutsches Elektronen-Synchrotron DESY) In a global observation campaign, scientist have for the first time located a source of high-energy cosmic neutrinos, ghostly elementary particles that travel billions of light years through the universe, flying unaffected through stars, planets and entire galaxies. The campaign was triggered by a single neutrino that had been recorded by the IceCube neutrino telescope at the South Pole. Scientists from the 18 different observatories involved are presenting their findings in the journal Science.
