Vector arrows wouldn’t hurt, either.

Presumably, the little one came in from the right somewhere, judging from the stretched spiral arm, but above or below? And where is that tidal tail? Was it “blown off” perpendicular to the “collision”. Perpendicular to which axis? A bow wave? A wake?

I think it was here that I saw a time-lapse picture of something far away that we’ve been observing for decades (some nebula perhaps?) and stuff moved about 5 pixels, but it was 10s of light years. The app needs zoom, fast forward, and rewind features.

Maybe there is a supercomputer that can calculate that relative to the motion in the stars in the two galaxies. I just find it difficult to believe that two “buzzsaws” met in the exact same eccliptical plane.
