Abstract:
Knowledge about cosmic rays above 10^19 eV has greatly improved through the successful operation of the Auger Observatory in Argentina where more events above 10^18 eV have now been recorded than from the sum of all previous efforts. I will outline the reasons for interest in this field, describe the Observatory and review our latest results on the mass composition, the energy spectrum and the anisotropy of what are the highest energy particles in Nature.
