blender model used particals and physics for this. If there is any problems let me know and i will fix. Apparently it is blender render rather than cycles though I am pretty sure I made it in cycles on my old laptop
What do you mean by visible distinct boundary you mean the end of the galaxy?
The white line along the rim is too visible if he could extend it out of the camera view.
I thought this, too, and realized when I switched to "render layer" from "compositing" the white line went away and I got a much better result. The photo above isn't the best result possible from this file.
Right now I'm working on trying to get the galaxy to spin with the arms trailing, rather than leading. I know they can spin either way, but to me it looks more natural if the arms trail the motion. Overall, a great piece.
FYI to other users--it's actually a Blender Render even though it's listed as Cycles.
Odd cause I used cycles when I rendered this and made this on my old laptop guess I will have to see if I still have the file if not I will just download it and try to fix it and maby animate it.
This user as just reposting the original blend of "cpkmexico".

Very nice model. Did you ever find the Cycles version? Please include a link to that if you have it. Thanks!
It fades out into space and it does not have a visible distinct boundary with that said its still a great render, the color variation and the glow in the center looks cool.
