Pretty pictures from Cassini's weekend flybys of Enceladus and Tethys

Emily Lakdawalla • April 16, 2012

Cassini flew past both Enceladus and Tethys on April 14. Here's a cool animation of its approach to Enceladus' plumes, and a pretty global picture of Tethys.

Pretty picture: Enceladus, in lovely color

Here's an awesome picture to start off the week. The data came from Cassini's flyby of Enceladus on January 31, 2011; it was part of Cassini's January 2012 data release.

More radar images of icy moons from Cassini: Iapetus, Enceladus, and Rhea

When I posted about the really cool Cassini SAR images of Enceladus a few weeks ago, I initially wrote that this was the first-ever SAR image of an icy moon other than Titan. Several people (some readers and two members of the Cassini science team!) corrected that statement: Cassini has performed SAR imaging of other icy moons (including Enceladus) before.

First-ever high-resolution Synthetic Aperture Radar image of Enceladus

On the November 6, 2011 flyby of Enceladus -- the third such flyby in just a few weeks -- the Cassini mission elected to take a SAR swath instead of using the optical instruments for once. So here it is: the first-ever SAR swath on Enceladus. In fact, the only other places we've ever done SAR imaging are Earth, the Moon, Venus, Iapetus, and Titan.

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

Emily Lakdawalla • October 20, 2011

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

Emily Lakdawalla • October 07, 2011

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.

Some first impressions of EPSC-DPS meeting

Emily Lakdawalla • October 03, 2011

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

Emily Lakdawalla • September 28, 2011

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

Emily Lakdawalla • September 23, 2011

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.

Scale solar system presentation slide, a provisional version for you to review

Emily Lakdawalla • September 15, 2011

I'm preparing a talk for the Pacific Astronomy and Telescope Show here in Pasadena on Sunday afternoon at 1:45. I have spent the morning putting together a slide that I have long wanted to have for presentations.
