Direct link What Happened to Saturn's Rings?

10 Aug 2009, 00:00 UTC Adam Fuller from Columbia Astronomy 400 years ago Galileo turned his telescope towards Saturn and saw what he thought were three separate round bodies. For the next 50 years astronomers hotly debated the true nature of Saturn. Then, in 1659, Christiaan Huygens radically changed the debate with his book, System Saturnium. In it he provided the correct explanation of Saturn’s companions: that they were actually part of a large ring wrapping around the planet. In this podcast we’ll delve into the history of this groundbreaking insight and explain why Saturn is ringless tonight. Columbia University Astronomy http://outreach.astro.columbia.edu Adam Fuller is currently a graduate student in the Earth and Planetary Sciences department at Johns Hopkins University. He graduated from Columbia University with a B.S. in Astrophysics this past May. He also has a B.A. in Journalism from the University of North Carolina at Chapel Hill (How ‘bout them Heels!). His research interests include planetary science, meteorology, and astrobiology. Outside of school he is an avid marathoner, an undrafted NBA free agent, and a dedicated uncle to three proto-astrophysicists. ------------------------------------------------------------------------------------------------------------------------------ SPONSOR: Clockwork The 365 Days of Astronomy Podcast is a project that is publishing one podcast per day, 5 to 10 minutes ...
