SUMMARY: Instruments on board Cassini have confirmed that Saturn's faintest ring is being created by particles emitted by its icy moon Enceladus. Scientists are amazed that this tiny, supposedly dead moon has such active volcanoes. Some unknown process is heating up the interior of Enceladus, especially near the southern pole, causing this plume of ejected material. Most of the larger particles probably reimpact the moon, but the smaller ones are pushed into orbit around Saturn by sunlight.

Again, this has similarities to the plasma plumes (http://www.universetoday.com/am/publish/nasa_nsf_atmosphere.html?5122005) that I also mentioned in a previous thread (http://www.bautforum.com/showthread.php?p=617541#post617541). See also:
