Holey Hyperion!

Emily Lakdawalla • August 26, 2011

Yesterday Cassini passed unusually close by Hyperion, the oddly shaped moon that orbits Saturn just beyond Titan. Among the many cool images captured during this flyby were three that I used to make this neato view of Hyperion's crescent.

Pretty picture: Saturn from very close up

Emily Lakdawalla • August 24, 2011

I haven't checked in on Cassini lately. I went to the raw images page and found the frames for this very lovely, very close view of Saturn. It was taken by Cassini two days ago, as it was approaching periapsis.

Pretty picture: five moons for Cassini

Emily Lakdawalla • August 03, 2011

Explaining how to combine the red, green and blue images from a recent Cassini image session containing five of Saturn's moons: Janus, Pandora, Enceladus, Mimas and Rhea.

Pretty movie: Everything in the Saturn system is in motion!

Emily Lakdawalla • July 26, 2011

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.

Congratulations to the Dawn team on their orbit entry & pretty pictures!

Emily Lakdawalla • July 18, 2011

There's a new orbital mission on the map! As of Friday, the relatively small mass of the asteroid Vesta has finally taken hold of its new artificial satellite, Dawn.

Cassini animations: Rhea and Dione and Titan

Emily Lakdawalla • June 28, 2011

I've been mucking about in the Cassini data archives (as I often do when procrastinating) and unearthed a neat, if short, mutual event sequence of two crescent moons passing by each other.

Cassini finally catches Helene

Emily Lakdawalla • June 20, 2011

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!!

Color versions of the recent Titan & moon beauty shots

Emily Lakdawalla • June 02, 2011

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

Emily Lakdawalla • May 23, 2011

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.

Titan's lack of lightning

Emily Lakdawalla • May 19, 2011

It's a fact of life in science that not all of your hypotheses will turn out to be correct (or even verifiable at all). But there's a bias toward the publication of positive results -- the discovery of this, or the proof of that.
