e PAMELA satellite-borne experiment has presented new results on cosmic rays and in particular on antiparticles that can be interpreted in terms of dark matter annihilation or pulsar contribution. The instrument was launched from the Baikonur cosmodrome and it has been collecting data since July 2006. The apparatus is designed to study charged particles in the cosmic radiation, with a particular focus on antiparticles for searching antimatter and signals of dark matter annihilation. The apparatus comprises a time-of-flight system, a silicon-microstrip magnetic spectrometer, a silicon-tungsten electromagnetic calorimeter, an anticoincidence system, a shower tail catcher scintillator and a neutron detector. The combination of these devices allows charged particle identification over a wide energy range. This talk reviews the status of the apparatus and illustrates the most recent scientific results obtained by PAMELA.
