Pretty pictures & movies: Eye candy from two recent Cassini Enceladus flybys

Posted by Emily Lakdawalla on 2011/10/20 12:35 CDT

Cassini has completed two very close flybys of Enceladus in less than three weeks, one of them just this morning, and the images from that encounter have already arrived on Earth.

Saturnlit moon, sunlit fountains

Posted by Emily Lakdawalla on 2011/10/07 06:00 CDT

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.

Notes from Day 5 of the EPSC/DPS meeting: Saturn's storm, Phobos, and Lutetia

Today was (is) the last day of the Division of Planetary Sciences / European Planetary Science Congress meeting in Nantes, France.

Brief notes from Day 2 of the DPS-EPSC meeting

Posted by Emily Lakdawalla on 2011/10/04 11:18 CDT

It's been a very full day at the DPS-EPSC 2011 joint meeting. My day was less full than it might have been, because I overslept and missed most of the morning's session. I really needed the rest though so I think it was probably for the best!

Some first impressions of EPSC-DPS meeting

Posted by Emily Lakdawalla on 2011/10/03 11:55 CDT

Today they turned on the scientific fire hose at the Division of Planetary Sciences / European Planetary Science Congress meeting happening here in Nantes, France. My brain already feels full and I still have four more days!

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.

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.

Titan crater and programming note

The summer is winding to a close but it's not quite over for me -- by which I mean my children -- yet.

Holey Hyperion!

Posted by Emily Lakdawalla on 2011/08/26 05:43 CDT

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

Posted by Emily Lakdawalla on 2011/08/24 05:13 CDT

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

Posted by Emily Lakdawalla on 2011/08/03 09:57 CDT

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!

Posted by Emily Lakdawalla on 2011/07/26 06:28 CDT

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!

Posted by Emily Lakdawalla on 2011/07/18 05:08 CDT

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

Posted by Emily Lakdawalla on 2011/06/28 04:12 CDT

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

Posted by Emily Lakdawalla on 2011/06/20 04:41 CDT

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

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.

Titan's lack of lightning

Posted by Emily Lakdawalla on 2011/05/19 12:27 CDT

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.

Watch Saturn's storms spin with VIMS

Posted by Emily Lakdawalla on 2011/04/28 01:15 CDT

A lot of attention has been paid recently to a storm in Saturn's northern hemisphere that is large and bright enough to be visible from Earth, but Saturn's atmosphere actually features lots more swirling storms. They can be hard to see, at least in visible wavelengths.
