Pretty pictures: Dancing moons

Posted by Emily Lakdawalla on 2011/09/28 12:28 CDT

Since Cassini currently orbits Saturn within the plane of Saturn's rings, it has lots of chances to catch two or more moons in the same photo. One such "mutual event" happened on September 17, featuring four moons: Titan, Dione, Pan, and Pandora.

What I see in the first high-res Dawn images of Vesta

Posted by Emily Lakdawalla on 2011/08/02 11:22 CDT

I had to wait until the kids were in bed and the husband fed last night before I finally had time to sit down and really look at the Dawn images of Vesta. And I still hardly knew where to begin. This brand new world is just so different than others I've seen.

Amateur takes on the Dawn Vesta images

Posted by Emily Lakdawalla on 2011/06/24 10:12 CDT

I am pretty sure that the Dawn team put nearly every image they've taken of Vesta so far in the animation they released yesterday, which is awesome. It hasn't taken long for the amateur image processing community to pick that animation apart into its component frames and process the heck out of the individual images to produce some very fine looking images and animations.
