Wayne Pryor, professor of astronomy and geology at Central Arizona College, in Coolidge, is a member of the team that found supersonic geysers of water vapor and ice crystals on Saturn's moon Enceladus are coming from warm, probably liquid water in a shallow underground lake.
The report is published in the Nov. 27 issue of Nature. Four jets of water were detected in a giant plume of gas and dust from the south polar region by NASA's Cassini spacecraft.
There are contrasting interpretations, but this would put Enceladus on a par with Europa, as the only other bodies with possible liquid water besides Earth. And raises the potential for finding life.
