Two fine color Cassini animations: Prometheus rotating, Tethys and Dione dancing

Emily Lakdawalla • January 20, 2011

Daniel Macháček has reached into the dark side of Prometheus and pulled out an incredible amount of detail where the potato-shaped moon is illuminated by Saturnshine. He produced an animation that morphs among the three sets of four-filter color images that Cassini snapped during the flyby.

Emily Lakdawalla • December 28, 2010

Time to open the twenty-eighth door in the advent calendar. Where in the solar system is this cratered and streaked surface?

Pretty picture: Three moons of Saturn

Emily Lakdawalla • October 29, 2010

The Cassini Raw Images Website always offers rewards to the browser. This evening I found the raw images necessary to create this color composite, showing the hazy orange moon Titan, the mid-sized icy moon Dione, and the tiny rock Prometheus all at the same time.

Pretty picture: Crescent Dione

Emily Lakdawalla • September 10, 2010

I was busy with other projects today, so today's post just asks you to look at this gorgeous three-image mosaic of a crescent Dione, taken during Cassini's most recent flyby a week ago.

How to Recognize Titan from Quite a Long Way Away

Emily Lakdawalla • August 09, 2010

You know, I could fill this blog almost entirely with the amazing images that Gordan Ugarkovic locates, processes into prettiness, and uploads to his Flickr account.

Pictures hitting Earth from Cassini's close Enceladus flyby today

Emily Lakdawalla • May 18, 2010

Cassini flew within 436 kilometers of Enceladus' surface today. Although it's Cassini's 11th targeted flyby of Enceladus, these close buzzes are never routine.

Titan and Dione: The same, but different

Emily Lakdawalla • April 22, 2010

Here's a new lovely color composition of Titan and Dione captured by Cassini. This one was taken on April 20, 2010; a set of 15 raw images taken of the two moons just showed up on the Cassini raw images website.

Hey, I'm on APOD today!

Emily Lakdawalla • April 20, 2010

A big thanks to Bob Nemiroff, editor of NASA's Astronomy Picture of the Day website, for picking my composition of a set of Cassini photos of Dione and Titan for today's offering.

Dione and Titan

Emily Lakdawalla • April 12, 2010

It's axiomatic that as soon as I post about pretty Cassini pictures, another set of pretty photos will appear on the raw images website.

A feast of pretty pictures from Cassini

Emily Lakdawalla • April 12, 2010

Cassini has it almost too easy. Point at anything in the Saturn system and you're guaranteed of a shot that looks, at least, pretty.

A busy day for Cassini: Dione plus bonus Enceladus and Janus

Emily Lakdawalla • April 08, 2010

The Cassini Saturn orbiter just completed its second very close flyby of Saturn's mid-sized iceball moon Dione, and the images from that encounter have been streaming onto the Cassini raw images website this morning.

A trio of pretty Cassini pics

Emily Lakdawalla • March 19, 2010

It's been a little while since I posted any Cassini pictures just because they were pretty, so here's a few recent ones, produced by amateurs from the images available on the Cassini raw images website.

Hooray! Cassini's tour has been extended for SEVEN MORE YEARS!

Emily Lakdawalla and John Spencer • February 03, 2010

NASA has just announced that once Cassini's Equinox Mission runs out in June of this year, they will extend it a further seven more years, long enough for the spacecraft to see Saturn through its solstice!!

Highlights from the January 1, 2010 Cassini imaging data release

Emily Lakdawalla • January 13, 2010

The January 1, 2010 Cassini imaging data release includes everything acquired by Cassini from January 1 to March 30, 2009 in all its high-quality glory.

Awesome Mars Express view of Phobos and Deimos together

Emily Lakdawalla • December 11, 2009

My inbox was exploding this morning with messages about a tremendously cool animation released this morning by ESA's Mars Express team. It shows Phobos crossing Deimos, in what's known as a "mutual event."

Planetary Society Advent Calendar for December 1: Dione

Emily Lakdawalla • December 01, 2009

I've always loved advent calendars and the way they both managed and heightened my anticipation of the gift-opening frenzy of Christmas morning.

Showing off Saturn's moons

Emily Lakdawalla • February 19, 2008

There was a press release from the Cassini mission today about a pile of papers (14 of them!) being published in the journal Icarus about Saturn's icy moons. I haven't had time to read more than the overview article yet, but I wanted to come up with a graphic for an overview of Saturn's moons, and I couldn't resist delving into the massive database of Cassini images to produce something new

Mimas, Dione, Rhea

Emily Lakdawalla • May 31, 2007

There's been quite a lot of Mars on this page for the last week; it's time to remind ourselves that there are other places besides Mars in the solar system.

Dione's south pole

Emily Lakdawalla • April 09, 2007

Cassini got a nice "Voyager-class" view of Saturn's moon Dione yesterday, passing about 250,000 kilometers from the moon's south pole.
