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

Today the 365 Days of Astronomy podcast aired my contribution, What's in a Science Meeting?, about what scientists do at big meetings like the Division of Planetary Sciences.

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.

An awful lot of the talks in the Pluto session on Tuesday morning, October 5, at the Division of Planetary Sciences meeting spent more time focusing on how bad weather conditions were during the astronomers' attempts to view Pluto as it occulted background stars than they did on any measurements or science that came out from the data.

Last week I posted a stack of Voyager Mission Status Bulletins, which were once the main resource for space enthusiasts to follow the dramatic events and photos of an in-flight space mission.

In response to Emily's entry about finally getting her hands on a subscription to the planetary science journal Icarus, I thought I would report on an article from the most recent issue: Geology of the Selk crater region on Titan from Cassini VIMS observations, by Jason Soderblom and 11 other scientists.

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.
