Abstract. Since June 2008 the Pierre Auger Observatory, designed for the research of ultra high energy cosmic rays, is taking data in its final configuration. In this paper I will present a short overview of its recent scientific results. More specifically, I will discuss the all particle energy spectrum and the evidence for the GZK features, the measurement of the elongation rate and the resulting inferences on mass composition, the evidence for anisotropy in the subset of the highest energy events.
