  A series of 13 Chandra observations provided the deepest images of the Vela
PWN yet available. In addition to the fine structure of the inner PWN features,
a much larger and fainter asymmetric X-ray nebula emerges in the summed images.
The shape of this outer PWN is similar to that of the radio PWN. We also
present the spectral map of the Vela PWN that reveals a shell of soft emission
surrounding the inner PWN and an extended region of harder emission south-west
of the pulsar. This may indicate that the outer jet is supplying particles to
this region.
