New Map Hints at Venus' Wet, Volcanic Past

Venus is often referred to as Earth's twin, as the two planets share a similar size. But perhaps the similarities don't end there. A new infrared map from Venus Express hints that our neighboring world may once have been more Earth-like, with a plate tectonics system and an ocean of water. While previous radar images have given us a glimpse of Venus' cloud-shrouded surface, this is the first map that hints at the chemical composition of the rocks. The new data are consistent with suspicions that the highland plateaus of Venus are ancient continents, once surrounded by ocean and produced by past volcanic activity.

    • I can remember when the "sky is falling" people used to say Earth would soon be another Venus.
      I sincerely hope they are wrong.
