DPS 2012, Tuesday: Titan's surface

Emily Lakdawalla • October 17, 2012 • 4

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."

DPS 2012, Monday: Icy moons and a four-star exoplanet

Emily Lakdawalla • October 15, 2012 • 1

In the first full day of the annual meeting of the Division of Planetary Sciences of the American Astronomical Society, I listened to scientific sessions on icy worlds and on an exoplanet in a four-star system.

Happy Cassini PDS Release Day!

Emily Lakdawalla • October 08, 2012 • 2

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 • 2

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.

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 • 6

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

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

Emily Lakdawalla • May 22, 2012 • 5

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.

Methone, an egg in Saturn orbit?

Emily Lakdawalla • May 21, 2012 • 8

Cassini obtained its first high-resolution images of Methone on May 20, 2012. Methone is one of the smallest regular moons of Saturn, having a diameter of only about 3 kilometers. It was the first moon that Cassini discovered, very early in Cassini's mission at Saturn, in 2004.

Pretty pictures from Cassini's recent Dione flyby

Emily Lakdawalla • May 04, 2012

Cassini performed its last of three close encounters with Enceladus for 2012 two days ago, and followed the flyby with some spectacular images of Dione.
