The Pierre Auger Observatory studies the most energetic cosmic rays arriving at Earth, in the energy range from 10^17 eV up to 10^20 eV and beyond. More than 10 years data taking have led to major advances in our knowledge of the origin and nature of cosmic rays. We present a summary of the latest results, discussing the challenges on the astrophysical interpretation of the flux suppression observed above 4 10^19 eV imposed by the experimental results on the primary cosmic ray composition and anisotropy.
