Exploring the Origins of Cosmic Rays in the Milky Way
Cosmic rays have long fascinated scientists with their mysterious origins and powerful energy levels. These charged particles, which travel through space at nearly the speed of light, have been a subject of intense research and speculation for over a century. In recent years, Chinese scientists from the Chinese Academy of Sciences’ Institute of High Energy Physics have made significant strides in unraveling the enigma of cosmic rays by identifying a potential source within our very own galaxy, the Milky Way.
In a recent study published in Science Bulletin, Chinese scientists revealed the existence of a massive gamma-ray bubble within the star-forming region Cygnus OB2. This bubble, dubbed a "super PeVatron," has the remarkable ability to accelerate particles to super-high energy levels,...
