Is this merging or overlapping?

  • Joncox2016 by Joncox2016

    I am new to galaxy zoo. I think this is an overlapping image as the object in the above right of centre, whilst close enough to be potentially merging, there is no sign of effect on the galaxy in the centre which I would expect to see if merging was occurring. Is this a correct analysis?

    I would agree that is is nearly overlapping. The little galaxy is much more red, and probably much further away than the blue spiral. Possibly the spiral is closer to us than it is to the distant galaxy, but I would have to do some calculations to be sure.
