Found at SpaceWeather:

--- Space artist Merry Wooten anticipated the discovery two decades ago:



Wooten had a hunch that Saturn's powerful tides might cause geothermal activity on Enceladus. Her painting of the resulting ice-geysers first appeared in a planetarium show, "When Worlds Erupt," in 1986. ---

I want more. Where are other Enceladus artists?

Notice that for Saturn's rings to be almost parallel to the horizon, as they are in that painting, you have to be near one of the poles.

Is that true? I thought Titan's orbit was coplanar with the rings, and that its axial inclination is nearly zero wrt Saturn...if so, I'd expect the rings to look practically edge-on and level to the horizon from almost any point on Titan's surface.

However, the low elevation of Saturn with respect to the horizon does imply that the scene is set at a high latitude...whether north or south, I can't tell! tongue.gif

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

The fact that Saturn is close to the horizon only tells us that the site is close to one or the other edge of the sub-Saturnian hemisphere, where it will stay permanently, of course.
The angle of the rings tells us that we're at a high latitude: if the rings are straight up and down like this (|) then you're at the equator; if the rings are horizontal, you're at the N or S pole. These fellows must be at about 75° N or S; the longitude is a little harder to figure, but I guess around 60° or 300° (i.e., either 75 N, 300, or 75 S, 60)
But it can't be Enceladus, because Saturn is far too small. If not Titan, it could be Rhea perhaps.

Anyway, it is a cute thing about these pictures that they almost always show Saturn (or Jupiter) in the sky, and so you can pretty much figure out exactly where such a picture could be taken!
