There are also other possibilities for this photo.
1. There is an unassociated dust cloud that is between us and the galaxy and it is lit by light coming to us from the galaxy.
2. Radio wavelengths have been incorporated in the picture in the form of dust.
3. There is a dustcloud associated to the galaxy and it is being excited to a maser state. (Sort of like a laser).
Do you know what galaxy that is or it’s position? I can find out more about it if you can provide the information.
That’s NGC-7603. It shows two galaxies and two quasars connected by an obvious and visible stream of material with the cosmic objects centered in the stream. The chances of that happening via any sort of coincidence are basically zero. Again the objects are clearly part and parcel of the same thing and they have substantially differing redshifts.
