Time to open the sixth door in the advent calendar. Where in the solar system are these snowy slopes?

December really has arrived, and that means that the year is racing to a close. Continuing last year's tradition, I'm counting the days to the New Year with an advent calendar, where each

The Cassini Raw Images Website always offers rewards to the browser. This evening I found the raw images necessary to create this color composite, showing the hazy orange moon Titan, the mid-sized icy moon Dione, and the tiny rock Prometheus all at the same time.

Where's the Cassini Saturn orbiter going to be in the next week -- or hundred weeks? It's all already planned out.

Photos like this always make me think about how unimportant size is in determining whether one of the worlds of the solar system is an exciting place.

Periodically, usually after I've posted some images pulled out of an image archive, a reader asks me:

I was busy with other projects today, so today's post just asks you to look at this gorgeous three-image mosaic of a crescent Dione, taken during Cassini's most recent flyby a week ago.

A couple of weeks ago Paul Schenk posted a few really cool videos to his personal blog. Paul's subspecialty is the topography of icy moons, and he's been doing a lot of work on the moons of Saturn lately.

Over the last couple of days Cassini flew past Enceladus, Tethys and Dione, so there are lots of treats to see on the raw images website! You should go check it out for yourself, but here are a couple of real favorites.

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.

I've posted animations from Cassini before in which there are multiple moons moving around, but this is one of the coolest such sequences I've seen yet.

I've spent a pleasurable hour or so browsing over the latest release of images from Cassini to the Planetary Data System.

The Saturn system is always in motion, always changing. Saturn itself is a gas giant, with swirling storms, and like the other gas giants it has a host of moons flying around, perturbing each other's motions. And then there's the rings.

Four times a year, the Cassini mission releases three months' worth of data gathered from Saturn and its moons to NASA's Planetary Data System.

As promised last week, Cassini has delivered its best photos yet of the tiny moon Daphnis, the ringmoon that is responsible for carving out the skinny Keeler gap at the outer edge of Saturn's A ring.

Just a pretty picture post, a dramatic Cassini shot on the outer edge of the A ring captured earlier this month.

Every time I think Cassini has captured the coolest image of Enceladus ever, it does better.

Cassini flew within 436 kilometers of Enceladus' surface today. Although it's Cassini's 11th targeted flyby of Enceladus, these close buzzes are never routine.

Every time Cassini gets reasonably close to one of the moons of Saturn, whether the close approach is a targeted one or just an opportunistic encounter, its planners usually take advantage of the proximity to take a bunch of photos.

A good start to my day today: The New York Times' Lens Blog featured the
