A new analysis of images taken by Voyager 1 has revealed a giant landslide on the Jovian moon Io. On page 1514, the researchers who identified the slide say it may be a sign that movement along faults deep in Io's crust built many of its peaks. If so, say the authors, Io would be unique among the solar system's moons in having this style of tectonics, which is common on Earth.
