Two moons making waves in the rings

Emily Lakdawalla • June 18, 2010

Just a pretty picture post, a dramatic Cassini shot on the outer edge of the A ring captured earlier this month.

The most amazing image of Enceladus Cassini has captured yet

Emily Lakdawalla • May 19, 2010

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

A Martian Moment in Time, revisited

Emily Lakdawalla • May 12, 2010

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!

Saturn's hexagon recreated in the laboratory

Emily Lakdawalla • May 04, 2010

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.

Hubble turns 20

Emily Lakdawalla • April 23, 2010

Tomorrow is the 20th anniversary of the launch of the Hubble Space Telescope. It's hard to believe it's been going strong for so many years.

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.

Pretty picture: Rhea, rings, and two little moons

Emily Lakdawalla • April 06, 2010

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

Pointing at Helene

Emily Lakdawalla • March 10, 2010

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.

Hubble sees both of Saturn's aurorae

Emily Lakdawalla • February 12, 2010

Yesterday, the European wing of the Hubble PR machine released this cool image of Saturn and its aurorae, with an associated video.

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 Cassini mutual event movies

Emily Lakdawalla • December 23, 2009

I love posting animations of Cassini images that I compose from frames grabbed from the mission's raw images website, but they are shoddy compared to the versions that eventually come out from the mission's imaging team.

Planetary Society Advent Calendar for December 12: Saturn

Emily Lakdawalla • December 12, 2009

Cassini's amazing cameras have set a new standard for the quality, sharpness, resolution, beautiful color, and all-around spectacularness of images returned from the outer solar system.

Saturn's aurora, even better than before

Emily Lakdawalla • November 24, 2009

The Cassini imaging team have posted their own processed and captioned version of the Saturn's aurora movie that I posted a preview of about six weeks ago, and it was worth the wait.

Four moons and a ring

Emily Lakdawalla • November 10, 2009

Thanks to Mike Malaska for the tip on this one. The image is part of an animation that ends with Rhea transiting Saturn.

Planetary Radio Q and A: Saturn's Hexagon

Emily Lakdawalla • November 04, 2009

On "Questions and Answers" I answered this question: "How do they explain the hexagon near Saturn's north pole?"

Planetary Radio Q and A: Not-so-gassy giants

Emily Lakdawalla • November 04, 2009

On Planetary Radio's "Questions and Answers" I answered this question: "I read that Uranus got its tilt when it was hit by another object. What does it mean for a ball of gas to be hit -- wouldn't another object just pass through it?"

Spinning spokes in Saturn's rings

Emily Lakdawalla • October 21, 2009

Here's a neat animation captured last month by Cassini and assembled by Mike Malaska: spokes in Saturn's B ring.

Saturn shadows shift with the seasons

Emily Lakdawalla • October 19, 2009

So many goodies on the Cassini raw images website lately! I am especially excited when Cassini takes photos through red, green, and blue filters so that it's possible to create views that look roughly like what you'd see with your own eyes.

A brief word on Saturn's radius

Emily Lakdawalla • October 15, 2009

I've had two people write in to correct my Phoebe ring post from yesterday.
