The heart of the Vela supernova remnant
This is an image of the central region of the Vela supernova remnant, showing emission created by ``winds'' from the active dead star (a pulsar) at the heart of the remnant. This image is in so-called ``polarised emission'', where we measure the tendency for the radio waves to oscillate in a preferred direction. In Vela, the preferred direction is caused by a strong magnetic field. The ``cracks'' in the image are regions where the preferred direction of oscillation is scrambled by visps of intervening material.
