Title:
Enceladus Ice Geysers
Explanation:
Ice geysers erupt on Enceladus [ http://en.wikipedia. org/wiki/Enceladus_( moon) ], bright and shiny inner moon of Saturn. Shown in this false-color image [ http://photojournal…], a backlit view of the moon's southern limb, the majestic, icy plumes were discovered by [ http://antwrp.gsfc.…] instruments on the Cassini Spacecraft during close encounters with Enceladus in November of 2005. Eight source locations [ http://saturn.jpl.n…press-release-detail s.cfm?newsID=780 ] for these geysers have now been identified along substantial surface fractures [ http://antwrp.gsfc.…] in the moon's south polar region. Researchers suspect the geysers arise [ http://photojournal…] from near-surface pockets of liquid water with temperatures [ http://lamar.colost…] near 273 kelvins (0 degrees C). That's hot when compared to the distant moon's surface temperature of 73 kelvins (-200 degrees C). The cryovolcanism [ http://en.wikipedia…] is a dramatic sign that tiny, 500km-diameter Enceladus is surprisingly [ http://saturn.jpl.n…press-release-detail s.cfm?newsID=662 ] active. Enceladus ice geysers also likely produce Saturn's faint but extended E ring [ http://www.planetar…].
