Abstract: Significant progress has been made in understanding astrophysical jets, thanks to new multi-wavelength observations extending from radio up to high energy gamma-rays. In this paper, I will briefly overview recent highlights/progress in studies of AGN jets, focusing on the high-sensitivity X-ray and gamma-ray observations that may shed new light on the forthcoming VSOP-2 era. I will especially discuss the recent Suzaku observation of blazars as a probe of particle content in the jet, and the first important site of the shock acceleration in sub-pc scale. Large scale (kpc to Mpc) AGN jets recently resolved/discovered with Chandra X-ray observatory are also discussed in detail. Since the X-ray emission from large scale jets are thought to arise from high energy electrons above 10 TeV, this will provide a new clue to the jet dynamics and high energy cosmic-ray acceleration in powerful jet sources. Finally, I will briefly comment on the X-ray observation of an iron Kα line feature in a radio galaxy as a new probe of disk-jet connection in radio-loud AGNs.
