Intro Astronomy Class 1: Tour of the Solar System

Bruce Betts • February 11, 2014 • 1

Take a tour of the Solar System in the video of class 1 of Bruce Betts' Introduction to Planetary Science and Astronomy class.

Enceladus huffs and puffs: plumes vary with orbital longitude

Emily Lakdawalla • December 11, 2013 • 2

In which I finally get around to writing about a paper published last August: Enceladus' plumes sometimes spout more and sometimes spout less, depending on where Enceladus is in its orbit. This discovery was enabled by Cassini's longevity at Saturn, and we'll be able to follow up on it, as long as Cassini is allowed to complete its mission.

Europe Will Select Its Next Major Science Mission in November

Van Kane • September 25, 2013 • 2

The European Space Agency will announce two major science missions this November, one of which is likely to be devoted to solar system exploration.

Scale comparisons of the solar system's major moons

Emily Lakdawalla • July 10, 2013 • 16

A few presentation slides with pretty pictures, sized to scale, of the large moons of the solar system.

One Ocean World Among Many

Jim Bell • June 03, 2013 • 6

I'm absolutely floored when I stop to think that our beautiful blue ocean is only one of perhaps a half dozen or more oceans on other worlds in our solar system, and only one of probably millions (or more) oceans on other Earth-like planets in our galaxy. Oceans abound!

Planetary Society Weekly Hangout: Reports from the Lunar and Planetary Science Conference

Emily Lakdawalla • March 28, 2013 • 5

On Thursday at noon PDT / 1900 UTC I'll report on some of my favorite findings from LPSC, and answer your questions about the latest planetary science.

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.

Enceladus: A problem of contrast

Emily Lakdawalla • January 30, 2013 • 6

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.

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.

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.
