Hi,

I think this is an interacting pair of galaxies. If you click on the “NGC/IC galaxies” overlay, you’ll see that they are NGC 5614 and 5615, which according to Simbad are at roughly the same redshift:

The tail at the 1 o’clock position and the ring of blue star formation might have been triggered by this collision.

cheers,
