- "NASA's Fermi Space Telescope Finds Most Powerful Cosmic Ray Ever Detected" (February 2023)
NASA's Fermi Gamma-Ray Space Telescope has detected the most powerful cosmic ray ever observed, a high-energy particle that is likely to have originated from a distant galaxy. The cosmic ray, known as a "UHECR" (Ultra-High-Energy Cosmic Ray), has an energy of approximately 1.8 x 10^20 electronvolts, making it the most energetic particle ever detected.
