Haha, I totally knew that. I was just being a dick to see if he really knew what he was talking about or if he was just cut-and-pasting stuff.

Mars' atmosphere is like 95% CO2, and I think that if there is any water on mars it's only very small amounts in the form of water vapor present in the atmosphere.

Anyways, what do you mean when you say that Venus is 'glowing in the dark'? Do you mean that it's emitting light, or that it is more reflective for some reason?
