Eclipse Phase got it mostly right as new data provide the first geophysical measurements of the internal structure of Saturn's sixth largest moon that is consistent with subsurface oceans. That also makes it a candidate for microbial life. "The gravity measurements suggest a large, possibly regional, ocean about 6 miles (10 kilometers) deep, beneath an ice shell about 19 to 25 miles (30 to 40 kilometers) thick. The subsurface ocean evidence supports the inclusion of Enceladus among the most likely places in our solar system to host microbial life. " http://www.jpl.nasa.gov/news/news.php?release=2014-103
