"Unveiling the Mystery: Giant Space Bubble Identified as Cosmic Ray Source"
TL;DR
Astronomers have discovered a massive gamma-ray bubble in the Milky Way, known as a 'super PeVatron', which could be the source of the galaxy's most powerful cosmic rays. The region, located in the star-forming area Cygnus OB2, is capable of accelerating particles to energy levels exceeding 10 petaelectronvolts (PeV). This finding challenges previous assumptions about the maximum energy levels of cosmic rays in our galaxy and provides new insights into the origins of high-energy cosmic rays.
