How would the Earth look if it had a ring system like Saturn?

August 11th marks the coming of Spring to Saturn's northern hemisphere, when the 170,000 miles wide rings turn edge-on to the sun and reflect almost no sunlight. The rings are only some 10 meters (30 feet) thick and made of mud and ice. As Saturn shifts towards its once every 15 year equinox, out-of-plane structures will cast long shadows across the rings' broad expanse, making them easy to detect (previously). Though you can't see the rings with the unaided eye, professional and amateur astronomers have captured the gas giant in its transition towards the equinox.

Source Of Geysers On Saturn's Moon Enceladus May Be Underground Water. Earlier this year the Cassini spacecraft detected organic material in the geysers of Enceladus. The question now is, how's the fishing?

In Saturn's Shadow. Pictures of Saturn like none you've seen before, taken by Cassini while the planet was in between the probe and the sun. You can just make out Earth in the photos. Previously.

Stunningly beautiful photo of Dione and Saturn with rings. Such a sensation of depth and grandeur. Thanks, Cassini/JPL/NASA. [animation] [planetary photojournal entry] [B/W mirror from kokogiak] [now you play fun Flash spaceship game].

Cassini Flies by Tethys and Hyperion, and the photos so far have been awesome and weird. I especially want to point out this fascinating view, which, if you look at it closely, reveals what appears to be a string of small impact craters, in a straight line over older terrain. What kind of meteor impact could have produced such an excellent formation of craters? Hyperion photos are coming. (Kokogiak's got backup in case the JRUNS strike.)

Rocks Among the Rings. The Planetary Society's Emily Lakdawalla has compiled some of the loveliest imagery of Saturn's ring-and-moon system from Cassini. More on Saturn from the Planetary Society here. Also see the Cassini at Saturn photoset, from our very own kokogiak, and watch for updates on the latest Enceladus flyby.

It worked! Huygens has successfully landed on Saturn's moon Titan and the Cassini orbiter is sending good data back to Earth as I type. Isn't it amazing how we can take a probe the size of a compact car, send it on a 7 year journey in the most inhospitable environment imaginable, deploy a sub-probe that has been dormant for that entire time and land it where we had planned on another solar body so far away that it takes 67 minutes to get a signal back and forth. Exploration and research has never been so cool.

" It was beyond description, really, it was mind-blowing," she said. "I'm surprised at how surprised I am at the beauty and the clarity of these images. They are shocking to me."

The Solar System Simulator 'is designed to simulate - as realistically as possible - what one would actually see from any point in the Solar System. The software looks up the positions of the Sun, planets and satellites from ephemeris files developed here at JPL, as well as star positions and colors from a variety of stellar databasees, and uses special-purpose renderers to draw a color scene. Texture maps for each of the planets and physical models for planetary rings have been derived (in most cases) from scientific data collected by various JPL spacecraft.' Far too complicated for me to even begin to understand, still I've always wondered what Saturn looks like from Triton.

Cassini makes Jupiter flyby on way to Saturn. They successfully made their pass, picking up considerable velocity necessary to make it out to Saturn. [More inside]
