New Map Hints At Venus' Wet, Volcanic Past

Matt_dk writes with this excerpt from Space Fellowship: "Venus Express has charted the first map of Venus' southern hemisphere at infrared wavelengths. The new map hints that our neighbouring world may once have been more Earth-like, with a plate tectonics system and an ocean of water. The map comprises over a thousand individual images, recorded between May 2006 and December 2007. Because Venus is covered in clouds, normal cameras cannot see the surface, but Venus Express used a particular infrared wavelength that can see through them."

Think... think... think....

Nope, can't think of one.
