This scene's really not too complex. Its two spheres that I've texture mapped the moon's surface and the earth's surface to, a background of stars, and a black floor on which to allow for shadows, reflections, etc. I've a few spotlights above and behind, but trained on the earthy-sphere. In addition to all this I've got anti-aliasing, soft shadows, and glossy reflections turned on. I also had to do a bit of fussing with the attenuating-constants and light placement to get the half planet/half reflecty-metally look that I thought was pretty sweet.
