In this video excerpt from NOVA, learn about Titan, the largest moon of Saturn. Through radar imaging, scientists discover that Titan’s surface is covered with hundreds of lakes filled with liquid methane and ethane, making it the only world other than Earth that has a liquid on its surface. In activity six from the Education Collection that accompanies this video, students examine 12 cards that describe the habitability of the planets and six moons. Based on their assessment, students identify the top candidates for life in the solar system.
