The Oh-My-God particle was an ultra-high-energy cosmic ray detected on 15 October 1991 by the Fly's Eye camera in Dugway Proving Ground, Utah, U.S. It is the highest-energy cosmic ray ever observed. This particle's energy was unexpected and called into question theories of that era about the origin and propagation of cosmic rays. WebUltra-high-energy gamma rays are gamma rays with photon energies higher than 100 TeV (0.1 PeV). They have a frequency higher than 2.42 × 10 28 Hz and a wavelength shorter than 1.24 × 10 −20 m. The existence of these rays was confirmed in 2024. [1]
