Discovery Missions for an Icy Moon with Active Plumes

Van Kane • April 02, 2014

In December, scientists announced the discovery of possible plumes of water being ejected from Jupiters’s moon Europa. If confirmed, Europa would be the second moon with confirmed plumes after Saturn’s moon Enceladus. Two Discovery mission proposals for Enceladus suggest the types of missions that may be proposed for Europa.

Titan's lakes: The basics

Emily Lakdawalla • March 15, 2014

Since Seth MacFarlane tweeted that this weekend's episode of Cosmos was going to include a segment on lakes on Titan, I thought I'd write a post explaining the basics of Titan lakes.

Intro Astronomy Class 1: Tour of the Solar System

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

Polar vortices across the solar system

Emily Lakdawalla • January 09, 2014

Earth's polar vortex has been in the American news all week. But we're not the only planet that has one; basically every world that has an atmosphere has a polar vortex. Here are lots of pretty pictures and animations of polar vortices.

America's Pastime: Planetary Science

Apologies to baseball fans and others for the theme of this week's Planetary Radio preview, which has star player Emily Lakdawalla on deck.

DPS 2013: Tidbits from Titan

Emily Lakdawalla • October 09, 2013

I attended a few talks at the Division for Planetary Sciences meeting today that concerned Titan's origin and interesting surface, and then one in the afternoon about the atmosphere.

Europe Will Select Its Next Major Science Mission in November

Van Kane • September 25, 2013

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

Probing Titan's Atmosphere

Sarah Hörst • August 26, 2013

By now I hope that everyone has seen some of the spectacular images of the Saturn system (and especially Titan!) from the Cassini-Huygens mission. However, the measurements that often make my heart race are taken by instruments that reveal Titan in ways that our eyes cannot see.

Pretty picture: spectacular Saturn and Titan

Emily Lakdawalla • August 15, 2013

A lovely view of the ringed planet and its hazy moon seen from nearly behind them just a few days ago.

Terra Cognita

Bill Dunford • July 29, 2013

Pushing back the frontier, and filling in the blank spaces on the map.

Jani Radebaugh, Titan Explorer

Bill Dunford • July 23, 2013

Robotic space exploration is human exploration. Meet one of the people behind the machines.

Dunes on Tatooine

Ralph Lorenz • July 17, 2013

The fictional world Tatooine, scene of action in the Star Wars movies, is named after a town in Tunisia, where parts of the movies were filmed. The desert backdrops against which the movies were filmed are real terrestrial landscapes, which prove to be perhaps unexpectedly dynamic.

Scale comparisons of the solar system's major moons

Emily Lakdawalla • July 10, 2013

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

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!

The Shores of the Kraken Sea: Great Place Names in the Solar System

Bill Dunford • May 28, 2013

Nothing reflects the romance of deep space exploration more than the evocative names of places on the planets and moons.

Doing a science on Titan

Sarah Hörst • May 15, 2013

A tale from the scientific trenches: laboratory work to simulate Titan's rich atmosphere.

Meteor showers on Titan: an example of why Twitter is awesome for scientists and the public

Emily Lakdawalla • March 06, 2013

I use a variety of social networking tools to perform my job, but there's one that's more important and valuable to me than all the rest combined: Twitter. Yesterday afternoon there was a discussion on Twitter that exemplifies its value and fun: are there visible meteors on Titan?

Planetary Society Weekly Hangout, Thu Dec 20 1200PT/2000UT: Making Titan in the laboratory with Sarah Hörst

Emily Lakdawalla • December 19, 2012

Join us for our weekly Google+ Hangout Thursday at noon PT / 2000 UT. This week, I'm excited to have as a guest Sarah Hörst. Sarah is a postdoc at the University of Colorado whose current line of research involves experimental work on the complex atmospheric chemistry of Titan. She is also applying to be an astronaut!
