Moons get no respect. People think of them as dead and cold, often overshadowed (literally) by the superstar planets they orbit around. But planetary scientist Baptiste Journaux would disagree. He’s fascinated by moons and the growing research that has shown that moons are far more active than we used to think. In fact, they contain heat and ice and essential components needed for life. Pocket Science host Gabriel Spitzer talks with Journaux about the latest discoveries of frozen planets and the upcoming NASA mission to explore Titan, the moon orbiting Saturn.
