Possible merger of three galaxies

• by SeanWaugh

  Seems like these three objects are roughly the same distance, could we possibly have a three galaxy merger?

  You can look up the redshifts and photoz, which can sometimes give you a good idea. Though sometimes, it is not much better than estimating distance by colour with your eye.
