Indeed, the two red spirals(?) down in the left corner caught my eye. I wonder if they're orbiting each other? ....destined to eventually smash into one another? Also, all the faint fuzzies that are in the background....possibly *billions* of light years away.... simply amazing stuff!!
On the Hi-Res Visible only shot it looks as though each spiral has different structure.... looks as though there might even be an exchange of matter occuring ??
