Nice merger

  We all agree it´s a nice merger, but an odd one. What´s the blue thing at 7? a background galaxy or to do with voorwerpjes?

  The blue thingy at 7 is definitely another galaxy, but without additional information (spectrum) there is no way to tell whether it is close or background/foreground.
