  We have discovered that the radio nebula surrounding the Vela pulsar covers a
much wider extent than previously reported, with two lobes to the North and
South of the pulsar. Indications of this object have been reported previously,
but its symmetric morphology around the pulsar and other details had not been
identified as they were hidden due to poor sensitivity to low spatial
frequencies.
  The structure is highly polarised and the polarisation vectors, once
corrected for Faraday rotation, reveal symmetry with respect to the spin axis
of the pulsar. The X-ray emission found by Chandra lies at the centre of this
structure, in a region which has no detectable excess of radio emission. We
estimate total fluxes and regional fluxes from the Northern and Southern lobes,
plus the X-ray region at four radio frequencies; 1.4, 2.4, 5 and 8.5 GHz. We
present the corresponding images in both the total and polarised intensities,
as well as those showing the derotated linear polarisation vectors.
