Super-Kamiokande Finds Structure in the Cosmic Ray Sky

Cosmic rays, which are high-energy atomic nuclei driven by spectacular cosmic events, come to us from every direction on the sky. Most of them are destroyed high in the atmosphere, creating a shower of high-speed particles that penetrate sky and earth with ease. Surprising results from Japan's Super-Kamiokande underground observatory have recently shown that the distribution of cosmic rays on the sky is not uniform, a useful clue to the nature of these cosmic voyagers.
