Fragments of collision

  • davidrobertson by davidrobertson

    This seems to show an elliptical with a peripheral arc. My question is about the collision that formed it. There seems to be a trail of fragments to the left and two higher up. Is it possible that the white dot is the core of a small galaxy that impacted and dragged out a trail of stars which formed the 4 dots in between? Could the colour variation in the fragments indicate the amount of hydrogen collected by the stars during the collision? Is it usual that the impacting core is compact and white?

    The central gaaxy looks more like a disturbed spiral to me. At least oneof he objects to the left is also a galaxy. The smaller round ones are probably foreground stars from our galaxy So, not connected in any way with the central galaxy.
