Starship Asterisk*

All sorts of neat things in this picture. In the upper right corner there are two things that caught my eye.
1) What is going on with the red edge on spiral galaxy?
2) Are the two galaxies that are over lapping interacting or just in line of sight?

Starfish nebula.

Pretty Spirograph... Russia had that little brush with one awhile back, and it did not even hit, and still caused damage and harm....I don't think I want to be where one hits, especially if it is bigger.... :---[===] * Then there is the Tunguska event. Assuming it was asteroid related, it would be ...

An impressively important galaxy, and a beautiful one at that....Amazing!!! The galaxy in the upper right is interesting too.... :---[===] * Which one? In one tight area cropped out of the upper right area I count at least four galaxies and one foreground star. http://i76.photobucket.com/albums/j15...

I'm under the impression, maybe a false one, that all matter higher than helium has to be created in a star. So, a question about all this dust: is it all molecular debris from previously exploded/dead stars?

Thanks. I see the correct term should be 'satellite' and not 'background' galaxies.

Just out of curiosity, what are the two background galaxies (circled)?
