Due to unknown symmetries they could have lifetimes comparable to the age of the Universe. Velasco, S. Stolpovskiy, M. Preliminary results from the presently operating Alpha Magnetic Spectrometer AMS on board the International Space Station show that positrons in the cosmic rays arrive with no directionality?

There are also plans to aprticle a dedicated satellite or to instrument a flourescence camera on the ISS for observing extremely high energy CRs from space with much larger exposure [ 42] than expected for the Pierre Auger Observatory.

Glasstetter et al. Bibcode : iac! In common scientific usage,  high-energy particles with intrinsic mass are known as "cosmic" rays, an example of which is given in. Another type of test has been performed by investigating distributions of high energy hadrons observed in the shower core.
This magnifying effect of the earth atmosphere allows to instrument only a very small portion of the EAS area and to still reconstruct the major properties of the primary particles. From his observations, Pierre Auger already concluded that primary particles up to energies of eV are found in CRs. Primary energy spectrum in the knee region as obtained from different experiments. Diurnal variation of ionisation in hpysics vessels.
Bhattacharjee and G! G23 1. Stenkin, I. Haungs, V. Indeed, such a violation is expected from models of quantum gravity.
Cosmic rays are high-energy protons and atomic nuclei which move through space at nearly the speed of light. They originate from the sun, from outside of the solar system ,  and from distant galaxies. Data from the Fermi Space Telescope  have been interpreted as evidence that a significant fraction of primary cosmic rays originate from the supernova explosions of stars. The term ray is somewhat of a misnomer due to a historical accident, as cosmic rays were at first, and wrongly, thought to be mostly electromagnetic radiation. In common scientific usage,  high-energy particles with intrinsic mass are known as "cosmic" rays, while photons , which are quanta of electromagnetic radiation and so have no intrinsic mass are known by their common names, such as gamma rays or X-rays , depending on their photon energy. The precise nature of this remaining fraction is an area of active research.
