This image of Centaurus A has been overlaid with its composite radio image. The
radio lobes (shown perpendicular to the dust lane colored in blue, green and red)
are not visible optically but are clearly visible in the radio spectrum. It is common
for these lobes to extend far out from the core. The source of these lobes are the
same as the jets - synchrotron radiation.
The image is of elliptical galaxy M87. Using the Hubble Space Telescope
and using an infra-red and near UV filters, the core of the galaxy is visible
as is the emanating jet of synchrotron radiation. The jet is moving at
relativistic speed. The blue of the jet contrasts with the yellow glow from
the combined light of billions of unseen stars and the yellow, point-like
globular clusters that make up this galaxy.
