The most amazing image of Enceladus Cassini has captured yet

Posted by Emily Lakdawalla on 2010/05/19 01:05 CDT

Every time I think Cassini has captured the coolest image of Enceladus ever, it does better.

Pictures hitting Earth from Cassini's close Enceladus flyby today

Posted by Emily Lakdawalla on 2010/05/18 05:48 CDT

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.

New maps of Enceladus and other moons

Posted by Emily Lakdawalla on 2010/05/13 02:26 CDT

Every time Cassini gets reasonably close to one of the moons of Saturn, whether the close approach is a targeted one or just an opportunistic encounter, its planners usually take advantage of the proximity to take a bunch of photos.

A Martian Moment in Time, revisited

Posted by Emily Lakdawalla on 2010/05/12 02:30 CDT

A good start to my day today: The New York Times' Lens Blog featured the "Martian Moment in Time" photo that Opportunity took last week in a really nice writeup. I'm so grateful, and still a little surprised, that the folks on the Mars Exploration Rover mission took this idea and ran with it!

Radar glories in Titan rivers

Posted by Emily Lakdawalla on 2010/05/11 04:53 CDT

Wow, this is a cool paper. Here's the gist: the Cassini RADAR team has spotted some river channels on Titan that shine so brightly in radar images, there must be something special going on to explain that brightness.

Saturn's hexagon recreated in the laboratory

Posted by Emily Lakdawalla on 2010/05/04 12:32 CDT | 12 comments

A lot of readers have expressed interest in the origin of Saturn's north polar hexagon. The hexagon is a long-lived pattern in the clouds surrounding Saturn's north pole, which has been observed since the Voyagers passed by in 1980 and 1981.

Posted by Emily Lakdawalla on 2010/04/22 05:29 CDT

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.

Posted by Emily Lakdawalla on 2010/04/20 04:02 CDT

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.

A calming Titan

Posted by Emily Lakdawalla on 2010/04/19 03:35 CDT

Usually I like Mondays, but today I'm feeling a bit overwhelmed. When I get overwhelmed, I look at pictures from Cassini.

Dione and Titan

Posted by Emily Lakdawalla on 2010/04/12 05:03 CDT

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

Posted by Emily Lakdawalla on 2010/04/12 01:28 CDT

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.

Posted by Emily Lakdawalla on 2010/04/08 12:39 CDT

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.

Posted by Emily Lakdawalla on 2010/04/06 03:07 CDT

Here's a lovely picture whose components came down from Cassini a few days ago.

Mimas' cold region: another new mystery for Cassini to explore

Posted by Emily Lakdawalla on 2010/03/29 05:19 CDT

This new map of Saturn's moon Mimas -- representing data captured by the CIRS thermal infrared spectrometer during Cassini's February 13, 2010 flyby -- is just baffling.

A trio of pretty Cassini pics

Posted by Emily Lakdawalla on 2010/03/19 02:19 CDT

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.

It's the second time I've posted with this provocative title. This time, it's in response to a new paper published last week in Science.

Posted by Emily Lakdawalla on 2010/03/11 10:59 CST

Yes, it's yet another post on Helene! I keep on finding new stuff to post. This time it is a really cool montage assembled by Ian Regan.

Pointing at Helene

Posted by Emily Lakdawalla on 2010/03/10 11:40 CST

I posted already some neat images from Cassini's flyby of Helene last week, and commented on how most of the images from that encounter missed Helene entirely or only caught the moon at one edge of the camera field of view. Here's an example of one of those images.
