The gamma-ray polarization vector superimposed on a composite image of the Crab from Chandra (X-ray/blue) and the Hubble Space Telescope (optical/red). The vector is drawn so as to pass through the position of the pulsar. The limits on the direction of the vector are indicated by the shading. The direction of the polarization vector shows a remarkable alignment with the inner jet structure.
