Chinese Observatory's New Discovery, a Step Closer to Solving Cosmic Ray Enigma
China's cosmic ray observatory has discovered a giant ultra-high-energy gamma-ray bubble structure, about ten million times larger than our solar system, in the Cygnus star-forming region, around 5,000 light years from Earth. "This is the first super cosmic ray accelerator identified as of now. With increasing observation time, LHAASO is expected to detect more super cosmic ray accelerators, and hopefully solve the mystery behind the origins of cosmic rays in the Milky Way," said Cao Zhen, principal investigator of LHAASO and an academician of Chinese Academy of Sciences (CAS).
