Meet some worlds that were nearly shattered, literally.

I'm absolutely floored when I stop to think that our beautiful blue ocean is only one of perhaps a half dozen or more oceans on other worlds in our solar system, and only one of probably millions (or more) oceans on other Earth-like planets in our galaxy. Oceans abound!

Nothing reflects the romance of deep space exploration more than the evocative names of places on the planets and moons.

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

A tale from the scientific trenches: laboratory work to simulate Titan's rich atmosphere.

An easy image processing trick -- using lower-resolution color data to colorize a black-and-white photo -- is relied upon by many space missions to keep data volumes low. Here's how to do it.

On Thursday at noon PDT / 1900 UTC I'll report on some of my favorite findings from LPSC, and answer your questions about the latest planetary science.

Reports from the March 19 session at the Lunar and Planetary Science Conference covering eight icy moons in the outer solar system: Ganymede, Europa, Dione, Rhea, Mimas, Tethys, Enceladus, and Miranda.

I use a variety of social networking tools to perform my job, but there's one that's more important and valuable to me than all the rest combined: Twitter. Yesterday afternoon there was a discussion on Twitter that exemplifies its value and fun: are there visible meteors on Titan?

Look past the rings, and Saturn is even stranger--and more breathtaking.

When the sunlight catches it just right, Saturn's F Ring is something to see.

For the first time, amateur astronomers are capturing spectacular images of Saturn's bizarre north polar hexagon.

Time for my quarterly foray into the Cassini archival science data! The very first image I downloaded from the January 1, 2013 data release presented an interesting challenge to my image processing skill. I'll show you the pretty picture of Enceladus and then explain how I processed it.

Join us for our weekly Google+ Hangout Thursday at noon PT / 2000 UT. This week, I'm excited to have as a guest Sarah Hörst. Sarah is a postdoc at the University of Colorado whose current line of research involves experimental work on the complex atmospheric chemistry of Titan. She is also applying to be an astronaut!

Remember the amazing photo of Saturn's north pole that I posted yesterday? Now, thanks to an amateur image processor, it moves, and the motions of the individual clouds within the belts are mesmerizing.

Amazing photos have just come back from Cassini, of swirling clouds surrounding Saturn's north pole.
