kinda makes me wonder what venus would look like if we could terraform it

Not like the picture you commented on, this one was just the product of not having a suitably detailed altimetric map of the planet and not taking into account some factors that would make even present day Venus habitable, if it wasn't for the carbon dioxid blanket that covers the planet.

so if we got rid of all those greenhouse gasses do you think venus would have any chance of becoming earth like?

It would involve a lot more steps than simply removing its oppressive atmosphere and it would require a level of technological development we haven't reached yet, but in the future it might be doable. What I was referring to however was the fact it's been discovered that if the Earth rotated on its axis as slowly as present day Venus does on its own and orbited at same distance from the Sun, the ridiculously long solar day of the planet would compensate for the greater solar irradiation received.

It's because each solar day a planet with an earthlike atmosphere loses an amount of the heat received directly proportional to its solar day/solar year length ratio, 1/365 in the Earth's case.

so you're saying that another reason that Venus is so hot is because of it's super long ass solar day?

No, it's the opposite. If Venus had an earthlike atmosphere, it would lose into space a bit more than a half of the solar energy it received, because Venus' solar day is a bit longer than half of its solar year. If you factor in the fact Venus also gets almost double the solar irradiation the Earth gets, by average temperature, you would end up with a planet only slightly cooler than our own, with a daily thermal excursion growing ever harsher moving towards the equator, but nothing that would be considered out of the norm if comparared to the yearly thermal excursion regions with a continental climate experience on our own planet.

wow. XD that's hard to keep up with. I read it all but damn

And that's the dumbed down version XD

Basically, moving from either pole to the equator on Venus would be like moving from Seattle to Chicago, depending on the season you could either barely notice the difference or getting a heat stroke.

Dude! Nice! Where'd you get the images though? I've never found Venus surface maps 8192x4096 or higher, forcing me to fool with the images a lot to make them come out nice.

Thanks. It's partially what I've done as well, at least as far the height map of the planet goes (finding one on the net with greater resolution than 2048x1024 it's almost a urban legend). The surface map? I put together the pieces in the level 3 folder of a virtual texture I downloaded from www(dot)celestiamotherlode(dot)net, all 128 of them.

Thanks a lot, just wait until I upload the new and improved terraformed versions of Venus, the Moon and Mars. Mercury, Europa, Ganymde, Callisto and Titan are officially off of my list of terraformed planets because the resolution parts of them were photographed at just plain sucks.
