Radio/IR distant

    my first look at this is that there is not 3 individual occurrences yet 2. The circular shaped one is by itself and the other 2 are balanced around the 2 stars between them. Is this a possible reality? is all of this too far apart?

    Welcome to RGZ, mlab81!

    You are correct.

    In the center is a #compact, a single radio source associated with what looks like a star (SDSS J143233.63+091232.4), but is actually a very distant quasar (or QSO).

    To the bottom right (SE, in terms of directions; astronomers reverse E and W) is a classic #doublelobe. Its host is likely SDSS J143236.42+091157.7, which is likely a giant elliptical galaxy, the brightest in a cluster (however, it's possible the host is a different galaxy, close by on the sky). Here's a zoomed-in SDSS cutout of the field, centered on that galaxy:

    The two lobes are a nice distance apart, and you'll likely find many others at least as far apart; some are so distant that they don't even appear in the ARG field! These are cosmic beasts which some radio astronomers are actively seeking; they're called giants.

    Hope this helps, and happy hunting! 😃
