Nice shot of Rhea against Saturn taken on May 8 2010:

This is the exact same geometry as Planetary Photojournal Image PIA10494.

Great catch, Juramike!
Is it an RGB composition?

It was indeed. I was guessing it was a Cassini "Mother's Day" special, with Saturn, Queen of the Solar System, with her daughter Rhea.

Rhea behind the rings, May 11, 2010... I think the other satellite is in front of them.

Three-frame animation of Iapetus from May 7th, 9th, and May 12th observations (May 12th is RGB, May 9th was colorized to match):

False color zoom of Enceladus RGB = IR3, GRN, UV3. Lotsa wrinkly terrain, a couple narrow deepcrevasses superposed, and a splat crater with fresh white stuff.
(Note crater on left without the splat.)

What the...?
http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=216821

EDIT: OK, now I've figured out why it looks so weird. Low phase angle plus relatively fresh uncratered terrain. We're seeing albedo differences as much as light/shadow differences. Still, it's very weird looking!

Yes, unusual. Islands of old terrane in a active spreading zone?

It is "RGB"...


The (temporary) jawdropper in this batch was the saturnshine/crescent Dione (N00153920).

Does this 3D work for people? I can't tell if I'm really seeing 3D or if I am willing my brain to see it smile.gif

And the automatic contrast stretch is probably messing things up as there's probably no completely black space visible in this image - some shadows though.

Interesting that no one has mentioned this one...

ohmy.gif ...Thanks for pointing it out, VP. The upper-haze ring on Titan is just amazing in this context!

Emily, I think I see 3D in your image, but it sure is subtle. Is the surface relief here perhaps a lot less than you'd expect from the albedo & illumination variances?

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

I think your eyes did not discern the solid surface of Enceladus in the foreground... or did they?

Unbelievable.
