Though we now peer through its obscuring haze with radar, Saturn’s big moon remains mysterious. Cornell grad student Jason Hofgartner reports on the discovery of what appears (and disappears!) to be an island on one of Titan’s frigid lakes. Casey Dreier sits in for Emily Lakdawalla, and invites listeners to an event on Capitol Hill in DC. Bill Nye reports on the Orbiting Carbon Observatory-2 and the Planetary Society’s LightSail solar sail. Are those birds you hear in Bruce Betts’ What’s Up report?
