BeijingA 42-light-year X-ray tail matches once-unexplained gamma rays.
It offers a candidate answer to a century-old question: where cosmic rays originate.
China’s Einstein Probe satellite and a Tibetan Plateau observatory traced the tail to a pulsar 4,600 light-years away.
Researchers still need to confirm the pulsar wind mechanism against other candidate accelerators before ruling out alternatives.
