    Well, see... I don't know that I want to do that. 8-) I hear that the
earth has a ring, and it's too small to be visible from the ground. Whereas
Saturn's rings are almost a naked eye object from here.

    If I understand what rings are... an area in the orbit of the planet
where the tidal forces are too strong to support the formation of a planet,
but stable enough to collect debris. The denser the planet, the closer the
ring, the wider the potnetial area of disturbed forces. I could be wrong, I
usually research these things before typing them in stone, but I've got my 8
year old mind on today...

    Eh, I just looked on my old computer and I have some stuff that I wrote
a while ago that I can put on a web page, but I don't want to broadcast
anything I still have hopes of getting a publisher for...

I noticed that, too, a while back. I corresponded with one of the
Voyager illustrators on that. His response was (paraphrased): "Oh, I
don't want to get dragged in to another discussion about scale!  ;-)" 
[his smiley, not mine]. I got the feeling they had heard that one
before. The rest of the conversation was centered on artistic license.

It would be render a more realistic version of that scene. If anyone
does, I'll email it to the illustrator!

Jon

Yeah, you can see Saturn's rings from here, easily. But you can't
resolve them. ;-)

A reasonably good small telescope will show them to you.

A pair of field glasses and a steady hand will work too.

I agree with the original sentiment...

However, I think that this realstic image might be interesting... Often, in Trek, a
sense of scale is lost, that this is a tiny little ship in a planet filled with
humoungous structures.
