I assumed the "stars" were just schmutz on the picture (as in this real JPL shot of the north pole of Saturn), but a closer look at the picture I linked shows none on the planet itself, and when I look more closely, there's a lot of suspicious artifacts that indicate a rendering.
I found the photo on a quick Google image search, and assumed it was just one of many NASA shots posted by some space fan. But on checking out the website more closely now and going "upstream" a bit on the URL, I found that the site is indeed a forum for a rendering program
The forum album page the Saturn picture came from is here.
*blush* I had no idea what "A.M." stood for. Had it said "3DS Max" I like to think I wouldn't have been caught out so easily.
Still, it's interesting that the guy included the hexagon in his model. Has the existence of this feature been common knowledge for a long time?

Dang. You're right on that not being a real picture.
