LPSC 2013: License to Chill (or, the solar system's icy moons)

Emily Lakdawalla • March 27, 2013

Reports from the March 19 session at the Lunar and Planetary Science Conference covering eight icy moons in the outer solar system: Ganymede, Europa, Dione, Rhea, Mimas, Tethys, Enceladus, and Miranda.

The Stormscapes of Saturn

Bill Dunford • March 04, 2013

Look past the rings, and Saturn is even stranger--and more breathtaking.

Arc of Ice and Light

Bill Dunford • February 18, 2013

When the sunlight catches it just right, Saturn's F Ring is something to see.

Enceladus: A problem of contrast

Emily Lakdawalla • January 30, 2013

Time for my quarterly foray into the Cassini archival science data! The very first image I downloaded from the January 1, 2013 data release presented an interesting challenge to my image processing skill. I'll show you the pretty picture of Enceladus and then explain how I processed it.

That amazing image of Saturn's north pole just got better: now, it moves!

Emily Lakdawalla • November 28, 2012

Remember the amazing photo of Saturn's north pole that I posted yesterday? Now, thanks to an amateur image processor, it moves, and the motions of the individual clouds within the belts are mesmerizing.

Staring into Saturn's baleful eye

Emily Lakdawalla • November 27, 2012

Amazing photos have just come back from Cassini, of swirling clouds surrounding Saturn's north pole.

Watching the slow shift of seasons on Titan

Emily Lakdawalla • November 06, 2012

A sharp-eyed amateur noticed two images of Titan taken 20 months apart from nearly exactly the same perspective, and they illustrate how the shifting of Saturn's seasons has brought change to Titan's atmosphere.

A huge color global view of Dione

Emily Lakdawalla • October 23, 2012

From the Cassini data archives comes a huge (5000 pixels square!) color image of Saturn's icy moon Dione, worth investigating from both near and far.

DPS 2012, Tuesday: Titan's surface

Emily Lakdawalla • October 17, 2012

Tuesday morning at the Division of Planetary Sciences meeting featured talks on the surface composition and landforms on Titan, including lakes and "hot cross buns."

Happy Cassini PDS Release Day!

Emily Lakdawalla • October 08, 2012

It's a quarterly feast day for me: the day that the Cassini mission delivers three months' worth of data to NASA's Planetary Data System. Here's a few images processed from the October 1, 2012 data release.

Sturzstroms on Saturn's Moon Iapetus

Kelsi Singer • October 01, 2012

Long-runout landslides (sturzstroms) are found across the Solar System. They have been observed primarily on Earth and Mars, but also on Venus, and Jupiter’s moons Io and Callisto. I have just published a paper about sturzstroms on Iapetus.

A couple of gems from the archives

Emily Lakdawalla • September 10, 2012

We're still working on migrating content from the old to the new website. This week, that means I am looking, one by one, through some great amateur-processed space images.

What's Up in the Solar System in September 2012

Emily Lakdawalla • August 31, 2012

It's an active time in interplanetary exploration! Curiosity has begun roving Mars, and Opportunity's not wasting any time either. Dawn has just departed Vesta and begun the more than two-year cruise to Ceres. Juno is in the middle of a big deep-space maneuver, setting up next year's Earth flyby.

Saturn's still there

Emily Lakdawalla • August 22, 2012

A pretty picture of Cassini's current view of Saturn.

Daphnis cruises through the Keeler Gap

Jason Davis • August 16, 2012

What's up in the Solar System in August 2012

Jason Davis • August 03, 2012

Welcome to the monthly roundup of our solar system's envoy of electronic explorers! All eyes are on Curiosity as it approaches Mars this weekend. Who will lend support at the Red Planet?

Pretty picture: Meet Tethys

Emily Lakdawalla • June 20, 2012

Just a pretty global view of one of Saturn's flock of icy moons, newly processed from archival data by Gordan Ugarkovic.

Pretty picture: Halo on a halo?

Emily Lakdawalla • June 15, 2012

An interesting set of images of Titan that Cassini took recently shows a peculiar cap at Titan's south pole.

More Venus transits in 2012

Jay Pasachoff • June 07, 2012

A transit of Venus as seen from Jupiter may be observed by Hubble on September 20 and a transit of Venus as seen from Saturn will be observed by Cassini on December 21.

Video: Saturn makes its own drama (with a little help)

Emily Lakdawalla • May 22, 2012

The apparently simple device of running Cassini images together like a flipbook makes for a dramatic movie, especially with the help of well-timed musical cues.
