Today's IPOD image of Venus shows that the surface bears few impact craters. At Venus, something appears to be resurfacing the entire planet? like Jupiter's moon, Io? Volcanism? Corrosive atmosphere? Where IS all that sulphuric acid coming from if naught volcanoes? How much of Venus' atmosphere sublimates into space annually? How much is replaced? Does Venus outgas sulphur like Earth outgasses methane? What does that say about its evolution? Did it actually evolve around Sol? or was it perhaps 'captured' during a close encounter with another star or brown dwarf? Odd planet.. Venus.
