Yes, in late 2008, scientists observed water vapor spewing from Enceladus\'s surface. This could indicate the presence of liquid water, which might also make it possible for Enceladus to support life. Candice Hansen, a scientist with NASA\'s Jet Propulsion Lab in California headed up a research team on the plumes after they were found to be moving at ~2,189 kilometres per hour (1,360 miles per hour). Since that speed is unusual and is usually attained when water is involved, they decided to investigate the compositions of the plumes.

Evidence from the Cassini probe points to a possible global liquid ocean beneath the frozen surface.Particles of ice analysed by Cassini revealed that the ice was of salt water which could, it is surmised, only occur in a large liquid body of water, as such Enceladus is a candidate for the harbouring of extraterrestrial life. An alternative interpretation of the results is of large water filled caverns.
