    I don't think there's much doubt that the source is the #green SDSS J144932.94+262406.7:

    If its redshift is indeed ~0.3, then it's likely a Green Pea (GP). I don't know how many GPs are known to be radio sources; if only a few, this could be very interesting indeed! 😃

    It isn't a star, because there are no stars, which have truely a green colour! This object is truely green, isn't it?
    So I guess, that it is either a GP galaxy (with an AGN?) or it is a QSO!

    EDIT:
    There is the section THE PROPERTIES OF NARROW LINE SEYFERT1 PEAS
    in the paper, where the discovery of the Green Peas had been announced!.:

    @A1001

    You might want to inform about this object in following discussion, which was started by a scientist.:

    Green Galaxies associated with RGZ sources.

    EDIT: UPDATE: I informed about it overthere!

    @A1001

    I think, that another title for this discussion might be better because of the post by Jean. So you might want to change the title.

    Suggestion for a new title: "EDIT: A Green Pea?"

    (The original title is.: "ARG0001xwj STAR or GALAXY the radio source?")

    I don't think it is GP, rather a z ~1 QSO as usual

    In the paper, where the discovery of the GPs had been announcd, there is given following statement.:

    To define colour selection criteria, we compared the sample of ∼100 Peas identified by the Galaxy Zoo volunteers to a com- parison sample of 10,000 galaxies and 9,500 QSOs at the same redshifts over the colour space defined by the 5 SDSS bands. The 10,000 galaxies were selected to match the redshift and g-band- magnitude distributions of the Peas. The QSO sample contains all spectroscopically confirmed QSOs in the Peas’ redshift range, because the QSOs are overall too luminous to match the Peas magnitude distribution.
