Associated with the pulsar B0833-45, Vela X has been observed at different wavelengths and in particular in and X-ray bands. The H.E.S.S. Cherenkov telescope array has observed Vela X in 2004 and 2005, discovering very high energy gamma-ray emission in this region, centered to the south of the pulsar, and contained within a region of 0.8 degrees radius. Additional observations from 2006 to 2009 allowed further investigation into the Vela X non-thermal emission. In this work the latest results on the Vela X gamma-ray emission are presented in the context of a multiwave-length analysis. %G English %Z HESS %2 https://hal.in2p3.fr/in2p3-00461297/document %2 https://hal.in2p3.fr/in2p3-00461297/file/icrc0641.pdf %L in2p3-00461297 %U https://hal.in2p3.fr/in2p3-00461297 %~ IN2P3 %~ X %~ UNIV-SAVOIE %~ UGA %~ LPTA %~ LAPP %~ LLR %~ CNRS %~ UNIV-MONTP2 %~ X-LLR %~ X-DEP %~ X-DEP-PHYS %~ UNIV-MONTPELLIER %~ USMB-COMUE %~ UM1-UM2
