Cosmic rays, high energy particles originating from outside of the solar system, are believed to be dominated by particles from our Galaxy at least up to the energy of 10^15 eV. Since the discovery of these particles in 1912, the origin, acceleration and propagation of these high energy particles have remained as century old questions. In the last few years, new results from space-borne experiments, such as the rise of the positron flux and hardening of the light nuclei, have begun to challenge our understanding of these particles.
