2. How much of a temperature drop would it be for those in the shadow of the rings?

It would be like a weird season within fall/winter/spring as the shadow passed over.

3. I don't think it would be that dark a shadow

The sun shining through the debris that makes up the rings would be a lot weaker, possibly like just before sunset or just after sunrise. The rings aren't solid.

I just think it unlikely we'd get both moon and rings. Looking up into the night sky and seeing the partial arc of the rings would be neat as hell, though.

16. At least one of Saturn's rings are the result of a moon

http://www.nasa.gov/mission_pages/cassini/whycassini/cassini20110921.html

Chalk up one more feat for Saturn's intriguing moon Enceladus. The small, dynamic moon spews out dramatic plumes of water vapor and ice -- first seen by NASA's Cassini spacecraft in 2005. It possesses simple organic particles and may house liquid water beneath its surface. Its geyser-like jets create a gigantic halo of ice, dust and gas around Enceladus that helps feed Saturn's E ring. Now, thanks again to those icy jets, Enceladus is the only moon in our solar system known to influence substantially the chemical composition of its parent planet.

The images online are beautiful!!

15. The night time reflection might make up for it.

Here is a picture from the back side of Saturn taken by Cassini. You can see how the light stretches around.



The highlighted area is a little planet known to astronomers as "Earth."

7. I would miss seeing...

All the stars in the night sky. If the rings were as bright as the full moon the light would not allow so many to be seen.

Although the rings would be cool, 'specially if in color.

I'm sure some jewelery store would try to use them for advertising. lol

10. What would the ancients have thought of them?

They might not see them as rings, but arches. The way the appearance changes as you move north and south, Galileo may have been able to calculate their size and distance. The shadow of the Earth on the rings would produce lots of cool scientific speculation, and perhaps some crazy religious beliefs, too.

13. thats what I wonder

I think "the earth is clearly a sphere orbiting the Sun" would have been known (and more importantly--never doubted) from the beginning of civilization. This could have given us a huge leg up on science.

OTOH , it does look quite like a bridge to Heaven.

14. They might have sent massive expeditions to seek the "end" of the skybow.

'Cause it sure looks like it comes down to the ground just beyond that line of hills . . . or maybe the other side of those mountains . . . or beyond that sea . . . Holy cow, we're back where we started!

11. "This video contains content from WMG. It is restricted from playback on certain sites."

WMG claims an animation of rings around the Earth and restricts videos from being played on DU?
