Shadows and Plumes Across Enceladus . ... Credit Copyright: Cassini Imaging Team , SSI , JPL , ESA , NASA Explanation: Why does Enceladus have ice plumes? The discovery of jets spewing water vapor and ice was detected by the Saturn-orbiting Cassini spacecraft in 2005. ... A leading hypothesis held that the source might originate from a deep underground sea, but another hypothesis indicated that it might just be ice melted off walls of deep rifts by the moon's tidal flexing and heating. ...
