[bonzelite]

yes. there it is. Iapetus the death star space station. nice pics by the way. beautiful.

 

[Swampcat]

<font color="yellow">"nice pics by the way."</font><br /><br />Thanks, bozelite, but I have to admit that this one was too easy. Usually these Cassini images require much more work than the MER images, but this one just fell together on the first try. Basically all I did was crop it.<br /><br />I guess I should compliment the Cassini imaging team for doing such a good job getting the raws on this one. <div class="Discussion_UserSignature"> <font size="3" color="#ff9900"><p><font size="1" color="#993300"><strong><em>------------------------------------------------------------------- </em></strong></font></p><p><font size="1" color="#993300"><strong><em>"I hold it that a little rebellion now and then is a good thing, and as necessary in the political world as storms in the physical.

These is odd about Hyperion, notice the yellowish tint, even after changing the hue and saturation level the yellow still stayed, is this another active moon? Is the yellowish substance sulfur? I'm sure in the coming weeks we will find out more....<br /><br />I used JPLs false color image of Hyperion and tried to convert it back to what it should look like and this is what I got.<br /><br />Notice in top left corner of the image is the original image that I used to convert it, as always I sharpened it and added contrast to the image.<br />PIA07768.7<br /><br /> <div class="Discussion_UserSignature"> Ron Bennett </div>

<font color="orange"> close-up look at the Saturnian atmosphere reveals small, bright and puffy clouds with long filamentary streamers that are reminiscent of the anvil-shaped Earthly cirrus clouds that extend downwind of thunderstorms. Dark ring shadows hang over the scene while the planet rotates beneath. <br /><br />The image was taken in infrared light (939 nanometers) with the Cassini spacecraft wide-angle camera on Oct. 29, 2005, at a distance of approximately 388,000 kilometers (241,000 miles) from Saturn. The image scale is 20 kilometers (12 miles) per pixel. The image was contrast enhanced to improve visibility of features in the atmosphere.<font color="white"><br /><br />I added color. <br /><br /></font></font> <div class="Discussion_UserSignature"> Ron Bennett </div>

<font color="orange">The source of geological activity on Enceladus is a mystery. "We're amazed to see ice geysers on this<br /> little world that was thought to be cold and dead long ago," commented Dr. Dale Cruikshank of NASA Ames<br /> Research center, a member of the visual and infrared mapping spectrometer team. "Some unexpected <br />process is vigorously heating the interior of Enceladus, especially the south polar region, and causing the <br />ejection of the plumes of ice particles."<br /> <br />As the icy plumes jet out from the moon, the larger particles probably follow paths that mostly bring them<br /> back to the surface, while the smaller particles are nudged by sunlight into orbits around Saturn.<br />"Most of these small particles probably re-impact the <br />moon, but the smallest ones eventually disperse as a result of radiation (light) pressure and interactions with<br /> Saturn's magnetosphere to form the broad E ring," said Dr. Mark Showalter of the SETI Institute, Mountain<br /> View, Calif. Thus, the E ring is currently being regenerated by some kind of geological activity in the<br /> interior of Enceladus. <br /><br />During the Cassini spacecraft's flyby on Nov. 26, the visual and infrared mapping spectrometer instrument<br /> measured the spectrum of the polar plumes of Enceladus. "We see a very clear signature of small ice <br />particles in the plume data, in the form of a strong absorption band at 2.9 microns in an otherwise <br />featureless spectrum," said Dr. Phil Nicholson, professor of astronomy at Cornell University, Ithaca, N.Y. <br />Nicholson is a member of the visual and infrared mapping spectrometer science team.<br /> <br />The visual and infrared mapping spectrometer images of Enceladus show not only the plume over the south<br /> pole, but also the dark side of the moon, silhouetted against a foggy background of light from the E Ring.<br /> Measurements of the spectrum show a very similar signature of small ice particles to that in the plumes,<</safety_wrapper></font> <div class="Discussion_UserSignature"> Ron Bennett </div>

"geysers"; Pools of hot water on the surface?

 

[telfrow]

Thanks for the color version of the "cloud tops" photo. I posted the B&W version in the Cassini thread a while ago, with the comment: "Wow!" Great photo. <br /><br />Looks like I have a new desktop background. Thanks again. <div class="Discussion_UserSignature"> <strong><font color="#3366ff">Made weak by time and fate, but strong in will to strive, to seek, to find and not to yeild.</font> - <font color="#3366ff"><em>Tennyson</em></font></strong> </div>

<font color="orange">"geysers"; Pools of hot water on the surface?<font color="white"><br /><br />I can't see pools of hot water on the surface unless there is some kind of dense atmosphere to support it however internal pools of hot water can exist. How cool is that. <br /><br />Over 40 percent of the radiation received on the earths surface from the sun is inferred, tidal force heating would give off inferred radiation from heated rocks. Sea creatures live at the bottom of the earth’s oceans more than 2.5 miles down where there is no visible light.<br /><br />Several of us here talked extensively about the possibility of tidal heating of the moons of Saturn on this board before Cassini arrived at Saturn, see if I can dig that up and bump it back from virtual space.......<br /></font></font> <div class="Discussion_UserSignature"> Ron Bennett </div>

Thanks <div class="Discussion_UserSignature"> Ron Bennett </div>

There is no doubt that water is oozing onto the surface from pools, but the magnitude, depth, and duration eludes me. Titan should have some similarities in this regard, with sufficient surface pressure to boot.
