Gavitational lensing or something else?
The radio sources in this image seem to very symmetrical. Could this be the effect of gravitational lensing?

The symmetry that you observe are #artefacts left over from processing the processing. These are called sidelobes and as we are trying to probe as close to the noise level as possible, these sidelobes will pop up. Have a look at this discussion board: http://radiotalk.galaxyzoo.org/#/boards/BRG0000005/discussions/DRG0000006 😃
