Résumé
HESS is a Stereoscopic Astroparticle Experiment situed in the deserts of Namibia at 1800m of Altitude. Four 12m Telescopes provide stereoscopic data that permits a unique way of diminishing background events and best angular resolution. Its main characteristics are low energy threshold (100Gev) and substantial flux sensitivity (1% Crab units). We prsent here recent results for Galactic and ExtraGalactics Object as well as some more in depth studies from Data collected in the region of the Galactic Center.
