Remember that sometimes encelados is cited like candidate it contain life.

http://photojournal.jpl.nasa.gov/catalog/PIA06208]Cool Picture! of Enceladus.

*Yes, that really is lovely. Looks almost touchable.

YL Rocket's first photo link in his March 17 post is spell-binding. The shadows of the rings on Saturn's upper hemisphere...always a visual treat. And the moons which are right in-line with the ring edges. :up:

:up:

Life on Europa? Good chance, I think. As for Enceladus? I'm more skeptical. But who knows...

*Crazy little moon. Tumbles "chaotically" in its orbit. Is thought to be the Solar System's largest irregular moon. Nice collage. Have seen a couple of other photos of Hyperion; glad for these additional images.

Cassini will do a flyby of Hyperion in September: Closest approach will be 615 miles.

Something must have smacked Hyperion pretty good, or it is the result of a large collision.

http://saturn.jpl.nasa.gov/multimedia/i … 1442]Mimas occults Janus

The movie was created from 37 original images taken over the course of 20 minutes as the spacecraft's narrow-angle camera remained pointed toward Janus. Although Mimas moves a greater distance across the field of view, Janus also moved perceptibly during this time. The images were aligned to keep Janus close to the center of the scene. Additional frames were inserted between the 37 Cassini images in order to smooth the appearance of Mimas' movement -- a scheme called interpolation. Close-up images from the few minutes surrounding the occultation are arranged into a strip along the bottom of the movie.

*Nice!

False-color pic which "enhances slight differences in natural color across" its surface.

The extreme north and south latitudes have a notable difference in hue compared to the mid-latitudes.

Pic taken 18 February 2005.

*And at a tilt. Taken March 6th. Can see vortices and cloud patterns.

*Whoops...ha ha ha. (Songs often come to mind...nevermind).

Nice pic of Dione. Distance of Cassini from the moon at the time was 808,000 miles. The "streaks" were first noticed by Voyager. They're really "an immense system of linear fractures."

Dione is 695 miles in diameter.

::EDIT:: Next Titan flyby is March 31. Will pass within 1,493 miles of Titan.

Truly a fabulous photo. Wish we could get a color version of it. Taken yesterday, March 25.

Contrast/brightness enhanced. Taken March 20. (In this photo it could pass for "the ghost of Mimas" -- the center especially looks like a very vague outline of that vast crater on Mimas)

Two large craters on day/night boundary? Left side is dimly lit by reflected light from Saturn. Taken February 18.

*Awesome pic, terrific song to go with (it -wouldn't- work with kilometers, nyaaa). There've been quite a few pics of moons and rings, but in this pic the rings are tilted just enough to allow a glimpse of layers. :up: Taken February 18. Prometheus in the photo.

I wish ESA would return some additional data from Huygens. :-\ Anyway, this pass by Cassini will take it to within 1500 miles from Titan's surface.

Go Cassini!

"Far-away fractures with strange-sounding names..."
Cindy:-

*Whoops...ha ha ha. (Songs often come to mind...nevermind).

Hmmm. I think I catch your drift, Julie .. sorry, Cindy.!
(Planetary science is one of my favourite things, too.)

Gas-giant planets in Sol's outer reaches;
Big moons like Titan with rivers and beaches;
Far-away fractures with strange-sounding names..
Dione's features in black and white frames.

Palely lit surfaces, craters, and patches;
Strange-looking fissures like pussy-cat scratches;
Plateaus all streaky and frozen in time;
If you're not awestruck it's surely a crime.

Planet-wide storms,
Gossamer rings,
All this beauty rare,
I think of them any time I'm feeling blue,
And then I don't seem to care.
:laugh:

Ah, a reference to my previous comment about Enceladus:

"Looks like some gargantuan cosmic cat had gotten hold of it as a toy."

Thanks Shaun, gave me a chuckle in more ways than one -- especially the last 2 lines. :;):
