Powerful cosmic rays believed to be from nearby pulsar discovered

Scientists have discovered high-energy cosmic rays that may originate from a nearby pulsar, after over a decade of data collection. These cosmic electrons and positrons, with energies over 10 tera-electronvolts, are 1000 billion times more powerful than visible light. Researchers from the HESS observatory in Namibia speculate that a pulsar, a few thousand light years away, could be the source.
