    Don't remember seeing this.

    Does NASA do September fools jokes?

    I cannot imagine anything so CGI being for real.

    They say it is an exaggerated color image, which means photoshopped to the death (using software with the price tag that makes Photoshop look free).

    What's the problem? Just looks like extreme enhancement of a real image. I do this all the time with my astrophotography, just alot less enhancement.

    Wonderful image. I have seen it featured on a number of televised documentaries.

    I love how it includes Earth as a brilliant white dot too

    Well it's a pretty image. Solar photographers do this with the sun. I've never of complaining from better detail..

    Is Saturn's surface that reflective? I thought it was a gas bag? Why don't the lines line up?

    If it's a composite, then I have no problem. Just don't tell me this is an enhanced photograph.

    disclaimer: I have never been to the far side of Saturn, nor do I know anything.

    The rings cast a shadow on the surface of the planet that seems to add or change them, since they are mostly transparent. It happens sometimes.

    A ha! After looking at about 1000 images of Saturn, I've figured out what I was misinterpreting. The rings reflect light back onto Saturn's surface primarily only towards one hemisphere. Here's another view:

    saturns_rings_reflect_a_lot_of_light.jpg

    There were actually three bugs I had to resolve:
    1. I didn't notice in the original image that the southern hemisphere was brighter than the north.
    2. The dark band at the equator is simply where the rings reflect/refract the least amount of light onto the surface.
    3. There is also an http://www.ciclops.org//view_media.php?id=14617" which points out something else I did not know. The rings look completely different depending upon from which side they are illuminated. This would explain why the rings in the shadow do not line up with, nor are they even the same width as, the rings in the sunlight.


    Mystery solved. The image is simply enhanced. And after only 4 hours of research, I know just about everything regarding Saturn and its moons.

    And I would like to thank everyone for their help.
