"Chinese Observatory's Breakthrough: Unveiling the Origin of Ultra-High Energy Cosmic Rays"
Chinese scientists at the Lhaaso Observatory in southwestern China have identified a bubblelike structure in the Cygnus constellation, around 10 million times larger than our solar system, as a super cosmic ray accelerator within the Milky Way. This discovery challenges previous theories about the origin and source of cosmic rays, shedding light on how ultra-high energy gamma rays may have originated. The structure, observed by the Large High Altitude Air Shower Observatory, contains multiple photons exceeding 1 PeV, and is believed to be powered by a massive star cluster called Cygnus OB2. The findings could potentially solve the century-long enigma of the origin of cosmic rays.
