Enceladus: Oasis or Ice Ball? - Exploring Saturn's Enigmatic Moon

Explore the fascinating world of Enceladus, Saturn's icy moon, in this 56-minute AGU Fall Meeting 2009 Shoemaker Lecture presented by Susan W. Kieffer from the University of Illinois. Delve into various aspects of this intriguing celestial body, including its size, composition, and unique features like the Old Faithful-like geysers. Examine the different types of observations, chemical makeup, and thermal properties of Enceladus. Investigate the South Polar Terrain, Tiger Stripe Terrain, and other tectonic regions. Learn about gas abundances, fractures, and crust models. Understand the thermodynamics and mechanics of how the Enceladus system works, drawing parallels with Earth phenomena like Yellowstone's geysers. Engage in a thought-provoking discussion that addresses the question: Is Enceladus an oasis or merely an ice ball?
