@garbageinhere: Clearly from your fabulous picture of Mars the valles marineris is not a natural formation and must have been created by intelligent life.

These are great, but... do we really know the topography of Venus thru that thick atmosphere?
btw... Civ map makers get on em!!

though Venus has got an atmosphere made of sulfuric acid, NASA already knows it's topography (so much

Radar imaging. Bounce radar off of the ground, and measure the time it takes for it to come back. Then you get the height at that point. (do it often enough, and you get a good map.)

Well the first topographic map was made back in the 90s. I guess it was before the web was huge, I remember watching an IMAX movie about it at the old Omnitheater when I was a young lad.

This pictures isn't my favourit but I've taken it by my own at university. I've used a 80cm(diameter) telecope on the Vienna Observatory. Integration time was around a minute per colour. It's a three colour composite of Johnson B(blue), V(green) and R(red). The galaxy is called M81.

How possible is terraforming? For Mars, Venus, and the Moon? Mars is the one they talk about most (but it seems so small!), Venus has an inhospitable atmosphere- IDK of anyway to change that, and the Moon just doesn't have an atmosphere, and AFAIK, you don't just conjure one up.

Well, all of them are difficult.
Mars primarily needs to have a thicker atmosphere, (vaporize water and/or dry ice there) and that will lead to higher temperatures.
Venus needs to have its CO2 locked away, and that will lead to it cooling off. (yeah... very difficult. The best I've heard of is smash lots and lots of ice asteroids into it so it can lock the CO2 away as carbonic acid when it reacts with the water, and then let that combine with the rocks and turn it into limestone.)
The moon the hard part is maintaining an atmosphere. Which leads to temperature and everything. Just not enough gravity. And little volatile materials to make an atmosphere. Best would probably just build domes around craters and fill it in with air. And seal off cracks where air can leak out. So no true terraforming.
Oh, we sent probes long ago. Those aren't interesting anymore. Just like we don't hear about WWII vets returning from WWII 60 years ago now.

come to think about it, the expression 'once in a Blue Moon' would be that much more... stupid!

Spiral Galaxy M81
Found it on Digg. Not pasting it cause it's MASSIVE and if you've got dialup then it'll take a fortnight.
Pretty though.
