The "contour explosion" has to do with the fact that the radio source is rather bright and are hard to deal with when making radio images. The star-like pattern is the response of the telescope and will look different for the different radio telescopes. The radio source is located at the centre of the pattern and the rest of the radio is artifacts.
And it's clear it's the faint blue 'star' which is the source:
However, for some reason the DR10 SDSS photometric pipeline doesn't recognize this as a photometric object! 😮
