Althouh the geyser plumes aren't very evident in this image, they are still visible, it is still a really cool one.

Hello I3p3r

Your right

harry the high quality quicktime one is the same quality as the 104mb gif but compressed better, so theres really no point :p

Hello All

Nice word ,,,,,,,remember,,,,,,,,,, I have had the flu for the past 2 weeks and my memory has gone hay wire.

The fly by movie is fantastic.

I'm downloading the 104mb version

flyby

... and remember the flyby. It doesn't show the geysers but it starts with the Tiger Stripes.

Here is another good picture of the geysere of Enceladus,
the moon Tethys and the gargantuan Titan as well as the rings of Saturn

Harry,
Don't forget this geyser photo

Great Huh?

The thermal avtivity is generated by friction between crust an internal layers and its rotation and the gravity of saturn trying to rip it apart.
Enceladus "Cold Geyser" Model

As Saturn's active moon Enceladus continues to spew icy particles into space, scientists struggle to understand the mechanics of what is going on beneath the fractured south polar terrain. This graphic illustrates key aspects of the model proposed by the Cassini imaging science team in a paper published in the journal Science on March 10, 2006.

The model shows how proposed underground reservoirs of pressurized liquid water above 273 degrees Kelvin (0 degrees Celsius) could fuel geysers that send jets of icy material into the skies above the moon's south pole. In the graphic, the vent to the surface pierces one of the "tiger stripe" fractures seen in Cassini views of the southern polar terrain (see PIA06247 for a look at the tiger stripes). Temperatures increase with depth.

Some combination of internal radioactive decay and flexing--perhaps concentrated within the tiger stripe fractures and brought about by the particular characteristics of Enceladus' orbit--is implicated as the source of the heat creating the liquid reservoirs. However, it is not yet clear how the deep interior of Enceladus functions, nor whether the moon is fully differentiated (separated into layers, with rock at the center and ice outside).

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.

In my humble opinion, drawings ( illustrations ) are nice but do nothing to generate discovery. A real photograph will. Pass me an ice cold one :D
