π China spots massive cosmic ray trail
Chinese scientists tracked an X-ray trail stretching 42 light-years across the cosmos by combining satellite and ground data. This research used China's Einstein Probe satellite and the LHAASO observatory near a pulsar 4,600 light-years from Earth. The trail runs in the same direction as ultra-high-energy gamma-ray radiation detected by LHAASO. This discovery shows high-energy particles don't diffuse uniformly after leaving their source. It offers new insights into how these powerful particles travel through interstellar space. π
