Did you know it is pronounced somewhat like “EhGEllodos” in Greek? But you can also resort to “EnCELLladous” in English….
Since the discovery of the mysteriously warm ‘tiger stripe’ crevasses and the remarkable geyser-like plumes of water vapor erupting from Enceladus’s southern regions, this icy moon has gone from an afterthought to a prime target for astrobiology.
During the years of the Cassini mission’s avatar-like presence in the Saturnian system we’ve seen increasingly convincing evidence that Enceladus is a lot more than just a brightly reflective ball of ice. To summarize all of this in simple terms: the moon has a large internal ocean of liquid, salty water.
That water jets out in visible plumes a few hundred miles high through a system of cracks and (we presume) deep plumbing through an icy crust that is probably anywhere from 10 km to 40 km in average thickness. In fact, so much effluvia jets out from Enceladus that it generates Saturn’s vast E-ring – encircling the giant planet at a roughly 200,000 km orbital radius. … (SciAm)
