Rays of extremely high energy, originating in outer space, which enter the earth�s atmosphere and, having undergone several transformations, can still be detected at great depths underground. The main component of these rays are high-energy particles (protons, helium nuclei, heavy atomic nuclei and leptons), as well as X-rays and γ-rays.
