我国发现最高能量光子
Chinese scientists have detected a dozen ultra-high-energy cosmic accelerators within the Milky Way, a find that could overturn humanity's understanding of the galaxy and help reveal the origin of cosmic rays, which have puzzled scientists for a century. The findings were based on the observations of China's Large High Altitude Air Shower Observatory, one of the country's key national science and technology infrastructure facilities, which is under construction in Daocheng, in Southwest China's Sichuan province.
由中国科学院高能物理研究所牵头的中国高海拔宇宙线观测站国际合作组近日宣布，中国高海拔宇宙线观测站(LHAASO拉索)在银河系内发现大量超高能宇宙加速器，这一发现可能颠覆人类对银河系的认识，并有助于揭示困扰科学家一个世纪的宇宙射线的起源问题。拉索是国家重大科技基础设施，位于四川省稻城县，目前仍在建设之中。
