Read this article: and then read how I changed it below: http://www.latimes.com/science/sciencenow/la-sci-sn-enceladus-moon-saturn-water-ocean-life-20140403,0,4555926.story
In 2005 Saturn’s Enceladus saw water start to roll - out of “tiger stripe” cracks near its south pole. Scientists thought that could be a sign of a liquid ocean beneath its ice shell, but they really could not tell. Now, with data from Cassini spacecraft, they have found gravitational evidence while they did the math. A lake superior sized sea - is in the south pole - could it be?.
This discovery, when you cross that line, shows that this tiny place could have some life signs.
313 miles across, Enceladus is too small and frozen boss, but Connected to saturn and Dione. Encell is not alone. Pulled by both bodies gravity is the reason for the cracks we see
Weren’t sure if it was coming from below or the ice on the surface though.
Scientists can’t see beneath the thick ice shell of moon we call Encell, One way they can see is by measuring certain points of gravity.. If the gravitation pull gets intense then it means below the surface is very dense; If the tug is weak without a fight then the surface is less dense and light.
During a series of passes over Encel’s terrain, Cassini measured the moon’s gravity strain using the Doppler radar up high in the stars: The signal stretched and squeezed when the gravity pulled like the breeze.
As Cassini passed over the south pole, the tug from the moon was stronger and that took its toll. Dent in Encel’s bottom so the gravity should be weak,. Not so, which meant there was something dense down below. It had to be water, water is denser than ice, thats why water makes it float so nice.
“There’s no other reasonable candi-DATE,” said Caltech’s David Stevenson,. “There is rock but that’s not the signal it creates.”
The scientists think there’s a sea that sinks 6 miles down,covered by a shell that covers 25 miles of ground. This could be as large as Lake Superior, based around the south pole, yet it could reach the north a bit as a whole. possibly a global ocean, at least a regional sea, based on the data from the gravity.
Encel’s been known to have sodium and a bit of potassium, as well as ammonia and methane inside it’s water vein. being spit out of its south pole. If it has organic molecules, in its layer of water it’s possibly habitable, cool.
But Bill McKinnon, Washington U in St. Lou, who was not involved, thinks Jupiters Europa is more likely to evolve: It’s more massive, volcanic activity. It also shot water from the south for us to see.
