Interacting galaxies with potential higher red shift

Very interesting distant case of interacting galaxies!

It does look interesting.

May I ask, how did you decide the two objects are at (potentially) quite different redshifts?

No, I don’t mean different red shift between the two galaxies. They should be the same if interacting. I mean just because of the color they should be relatively higher red shift than normal close to us galaxies where the color is not shifted as much do the red :slight_smile:

Oh, I see. Thanks for clarifying.
