Tethys and Dione don't seem to be active after all

Posted by Emily Lakdawalla on 2011/09/23 01:09 CDT

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.

Color versions of the recent Titan & moon beauty shots

Posted by Emily Lakdawalla on 2011/06/02 01:46 CDT

Last week I got very excited about a set of pictures that had appeared on Cassini's raw images website, but was sad that I couldn't make color versions myself. I was so excited that I failed to identify the little icy moon in the picture correctly.

Tantalizing photos of Titan, Dione, Tethys, and Saturn

Posted by Emily Lakdawalla on 2011/05/23 02:23 CDT

It figures. I just start a three-week trip, with my only computer a diminutive Netbook, and guess what's just been radioed across the 1.3 billion kilometers separating us and Saturn? A set of photos that should become -- when properly processed -- an iconic image from Cassini's fourteen-year mission to the Saturn system.

Two fine color Cassini animations: Prometheus rotating, Tethys and Dione dancing

Posted by Emily Lakdawalla on 2011/01/20 11:23 CST

Daniel Macháček has reached into the dark side of Prometheus and pulled out an incredible amount of detail where the potato-shaped moon is illuminated by Saturnshine. He produced an animation that morphs among the three sets of four-filter color images that Cassini snapped during the flyby.

Showing off Saturn's moons

Posted by Emily Lakdawalla on 2008/02/19 04:40 CST

There was a press release from the Cassini mission today about a pile of papers (14 of them!) being published in the journal Icarus about Saturn's icy moons. I haven't had time to read more than the overview article yet, but I wanted to come up with a graphic for an overview of Saturn's moons, and I couldn't resist delving into the massive database of Cassini images to produce something new
