Well that's the other problem I have with the comet scene, it's insanely 
slow to render! I have media for the earth's atmosphere, there's media for 
the comet's tail (turned off for this render to get it below 16 hours!) and 
the icy rocks have refraction, reflection, fade_colour, AND scattering 
media! So definitely not a cheap trick, more a ludicrously complex trick. 
But I agree the result is very pleasing, definitely worth the effort.

That grainy reflection spot will go away at some point, the earth's textures 
look terrible and are just placeholders.

I like the idea of throwing out the comet, my original idea didn't have a 
comet and was just meteors, but I wanted to see if I could get more things 
in the scene. Still if I remove the comet I can finish this scene in a lot 
less time, so maybe I can do both images before the deadline... that's an 
interesting thought...
