This is an interesting field. Here's SDSS zoomed out to about the same resolution as the WISE image:
The bunch of yellow balls (elliptical galaxies) in the center is surely the heart of a condensed galaxy cluster. Two of these (at least) have spectra (e.g. SDSS J110708.17+131306.4, z_sp=0.405), so the host of the nice double lobe is likely to be one of them (can't really tell which, neither the WISE nor FIRST have sufficient resolution).
The purplish-blue stuff in antikodon's post is several separate SDSS 'photometric objects', but I think they're all parts of the same irregular or disturbed Sd disk galaxy. None have spectra; however, the apparent core (containing the nucleus?) - SDSS J110705.34+131353.6 - has a z_ph of 0.059±0.031 and 0.062±0.023. And the other bits, classes as GALAXY, have similar z_ph's.
There is indeed an artifact in the SDSS image ... it looks like a line has been drawn across the middle, roughly horizontally, and the sky is noisier to the S. And that's just what has happened; the 'erupting black hole' (NOT!! 😦) that's creating the radio jets is near the border between two SDSS Fields:
