Saturn continues to surprise as scientists comb through 13 years of Cassini data.

Space is even more spectacular when you can see beyond what the eye can behold.

Google Maps released several new map products that allow you to see the locations of named features on many solar system planets and non-planets, spinning them around in space with your mouse.

Now that Cassini has returned to Saturn's equatorial plane, it has lots of opportunities to observe Saturn's moons. For about a week, Cassini has been taking regular sets of images of Iapetus, which I've assembled into an animation.

I've been resisting all urges to speculate on what kinds of geological features are present on Ceres, until now. Finally, Dawn has gotten close enough that the pictures it has returned show geology: bright spots, flat-floored craters, and enigmatic grooves.

A few presentation slides with pretty pictures, sized to scale, of the large moons of the solar system.

Meet some worlds that were nearly shattered, literally.

I've been out of town for a couple of days and am overwhelmed with work and an overflowing email box. So what do I do about that? I ignore what I'm supposed to be doing and play with Cassini raw image data, of course. Here is a

Clearly, this is Saturn, and its rings, and if you look closer you can see a tiny circle, on top of the rings, which is Mimas, and two stars in the background. It should look weird to you that while the rings are bright, Mimas is a black dot. What is happening here? Nearly everything in this picture is lit by light that has not arrived directly from the Sun.

About four years ago I wrote a blog entry about an ESA press release about paper published in Nature that suggested that Saturn's moons Tethys and Dione might have volcanic activity, like Enceladus. A new paper published in Icarus casts doubt on that conclusion.

I'm preparing a talk for the Pacific Astronomy and Telescope Show here in Pasadena on Sunday afternoon at 1:45. I have spent the morning putting together a slide that I have long wanted to have for presentations.

Explaining how to combine the red, green and blue images from a recent Cassini image session containing five of Saturn's moons: Janus, Pandora, Enceladus, Mimas and Rhea.

A few weeks ago a producer for a public television space documentary asked me if I knew of any cool Cassini animations and my answer was,

There's a new orbital mission on the map! As of Friday, the relatively small mass of the asteroid Vesta has finally taken hold of its new artificial satellite, Dawn.

Here are Ted Stryk's notes from the sessions he attended in the afternoon of Thursday, March 10, at the 42nd Lunar and Planetary Science Conference.

This is both a Lunar and Planetary Science Conference (LPSC) update and a public service announcement. Ted Stryk has been working for years to locate the original Pioneer 10 and 11 image data from the Jupiter and Saturn encounters.

Cassini's busy downlinking photos from yesterday's close pass by Enceladus, including some neat shots of Dione and this one where Mimas skipped briefly in to the field of view.

You know, I could fill this blog almost entirely with the amazing images that Gordan Ugarkovic locates, processes into prettiness, and uploads to his Flickr account.
