LHAASO discovers giant ultra-high-energy gamma-ray bubble, identifying the first super PeVatron
The Large High Altitude Air Shower Observatory (LHAASO) has discovered a giant ultra-high-energy gamma-ray bubble structure in the Cygnus star-forming region, which is the first time that the origin of cosmic rays with energy higher than 10 Peta-Electronvolt (PeV) has been discovered. This achievement was published in the form of a cover article in Science Bulletin on Feb. 26.
