Cassini Finds Titan's Seas Are Sand

Until a couple of years ago, scientists thought the dark equatorial regions of Titan might be liquid oceans. New radar evidence shows they are seas -- but seas of sand dunes like those in the Arabian or Namibian Deserts. A University of Arizona Cassini radar team member and colleagues report the findings in Science (May 5).
