Re: The Colliding Spiral Galaxies of Arp 274, spin direction

I doubt they're on the same plane, but agree they are not terribly far from it. ... Not very far indeed. Towards the top, it appears the left side galaxy is in front, towards the bottom, the right side galaxy seems nearer. I'm aware appearances can be deceiving, but look at the overlapping spiral a...

Re: The Colliding Spiral Galaxies of Arp 274 (2009 April 7)

There's an interesting looking object to the top-left of the two main protaganists in this picture. See the hot little orange spot inside a swirl of something? I can't tell whether that might be a star coincidentally in front of a far off galaxy, or the glowing centre of a relatively nearby nebula,...

Here is a source of some animations to help answer your questions. Science and art at the same time.
Looks like the galaxies are behaving much like smoke when they collide

The Colliding Spiral Galaxies of Arp 274 (2009 April 7)

The two colliding galaxies look like mirror images of one another. Do they turn i different directions or is that a just a visual effect? What will happen when they collide, will the spin come to a halt? Are they approching sideways (edge on) or will they collide disc on disc? Is there any way ot te...
