The Pierre Auger Observatory addresses the most fundamental questions about the nature and origin of the highest‐energy cosmic rays. The results obtained by the Auger Observatory have already led to a number of major breakthroughs in the field contributing to the advance of our understanding of these extremely energetic particles. The spectrum and the arrival direction distribution are key observables to search for sources or source regions of ultra‐high energy cosmic rays, and to understand the transition from Galactic to extragalactic cosmic rays. We present the latest results on the energy spectrum, and on the studies of anisotropies performed on the ten‐year dataset of arrival directions of cosmic rays at large and small angular scales. We also address the plans and motivations for the future upgrade of the Pierre Auger Observatory. (© 2015 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
