The Pierre Auger Observatory was built to help unveil the properties of ultra‐high energy cosmic rays with energies from 1017 to 1020 eV. In this paper we review the latest results obtained from data of the Pierre Auger Observatory in almost ten years of continuous operation and summarize what has been learned about the energy spectrum, mass composition, and arrival directions of cosmic rays in that energy range. We also discuss some implications of these results for the full characterization of ultra‐high energy cosmic rays and for assembling a consistent description of their origin, propagation, and composition.
