Planetary Society Advent Calendar for December 9: Atlas
Here's another weird-looking one, though it's less weird from this particular, polar point of view than it is when viewed from the side.
Planetary Society Advent Calendar for December 5: Epimetheus
Epimetheus is one of the many small moons of Saturn that are referred to by the Cassini mission team as
Planetary Society Advent Calendar for December 1: Dione
I've always loved advent calendars and the way they both managed and heightened my anticipation of the gift-opening frenzy of Christmas morning.
Saturn's aurora, even better than before
The Cassini imaging team have posted their own processed and captioned version of the Saturn's aurora movie that I posted a preview of about six weeks ago, and it was worth the wait.
Two more awesome pictures from the Enceladus flyby
I'm getting to be a broken record here, but I can't stop looking at these photos from the Enceladus flyby.
Prepare for your jaw to hit the floor when you see these pictures of Enceladus
Wow, just wow. I didn't know what to expect from the second flyby of Saturn's geyser moon Enceladus in November, which happened yesterday.
Another great Enceladus shot
Here's a 4-frame mosaic of Enceladus images -- just another everyday spectacularly alien landscape.
Opportunity's poking at Marquette Island; Cassini's catching dancing moons
Since tomorrow's class is going to be on playing with raw images from the rovers and Cassini, I've been playing with recent raw images from the rovers and Cassini! I just thought I'd share a couple of the fun items I've been working with.
Four moons and a ring
Thanks to Mike Malaska for the tip on this one. The image is part of an animation that ends with Rhea transiting Saturn.

Another marvelous image from Cassini's Nov 2 Enceladus flyby
This image goodie was produced from the raw images from Cassini's close encounter with Saturn's geyser moon Enceladus yesterday by Gordan Ugarkovic.
Cassini's Enceladus encounter, with bonus Tethys
Raw images from Cassini's close pass by Enceladus today started appearing on the JPL raw images website, and some less-compressed versions of a few of them showed up on the CICLOPS website.
Fun Friday photo: Titan and Rhea
Cassini recently captured a series of images documenting Rhea passing behind Titan.
What "phase angle" means
As is probably obvious by now, I love playing with spacecraft image data. I am always looking for excuses to dive into space image archives to unearth images of stuff in space that haven't really been seen by very many people before.
Spinning spokes in Saturn's rings
Here's a neat animation captured last month by Cassini and assembled by Mike Malaska: spokes in Saturn's B ring.
Saturn shadows shift with the seasons
So many goodies on the Cassini raw images website lately! I am especially excited when Cassini takes photos through red, green, and blue filters so that it's possible to create views that look roughly like what you'd see with your own eyes.
Fun for Sunday: Titan and Tethys pas de deux
Checking in on Cassini's raw images this weekend, there are several nice shots to play with, including the many frames from which I tossed together this cute animation.
Rhea, Enceladus, Mimas, and Tethys, oh my!
With the last Titan flyby on October 12, Cassini came back to an orbit that's nearly in the equatorial plane, and immediately rewarded us with some fine views of several of the icy moons. Here are a bunch of images of those moons.
A brief word on Saturn's radius
I've had two people write in to correct my Phoebe ring post from yesterday.
