Last week, the team put all of the data from Deep Impact's deep-sky imaging session online, and challenged visitors to see what they could make from it. I made some photos of M51, but there were some challenges.
Last month I posted a preliminary version of a slide I was working on for use in my public presentations, a slide that contains everything in the solar system bigger than 400 kilometers across, and invited comment. I've listened to all of your comments and corrections and come up with a second version.
It's been a week of very heavy science on this blog, so I thought it'd be nice to go into the weekend with a post in which a breathtaking picture speaks for itself, without needing my thousands of words.
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.
Here's a few pretty pictures that were recently dusted off by Ted Stryk. Pioneer 10 and 11 passed by Jupiter on December 4, 1973, and December 3, 1974, respectively. Here are three pictures from those two encounters, in versions newly processed by Ted from scanned photographic prints found during a research trip to NASA's Ames Research Center.
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.
A few weeks ago a producer for a public television space documentary asked me if I knew of any cool Cassini animations and my answer was, "Ooh, what a great excuse to have some fun digging around in the Cassini data archives." Here is the most fun animation I came up with in response to the request.
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.
Cassini has finally achieved gorgeous global imaging of Helene with a spectacular flyby on Saturday, in which they got Helene to pose prettily for the camera from beginning to end of the encounter. And what a wacky, wacky world Cassini has revealed Helene to be!!
