This letter reports rich X-ray jet structures found in the Chandraobservation of PKS 1055+201. In addition to an X-ray jet coincident with theradio jet we detect a region of extended X-ray emission surrounding the jet asfar from the core as the radio hotspot to the North, and a similar extendedX-ray region along the presumed path of the unseen counterjet to the Southernradio lobe. Both X-ray regions show a similar curvature to the west, relativeto the quasar. We interpret this as the first example where we separatelydetect the X-ray emission from a narrow jet and extended, residual jet plasmaover the entire length of a powerful FRII jet.Comment: Accepted for publication in Ap. J. Letters. 4 pages, 3 figure
