Episode Details

The celestial sphere is one of the most important concepts to teach in an introductory astronomy course. With the use of advanced video techniques and computer-generated graphics, students follow two star-watchers as they present the sky through their interactions with a digital skyscape. The lesson covers historical interpretations of the sky by earlier civilizations and the models of the cosmos they created. Comet hunter and astronomy writer David Levy anchors a diverse group of experts to deliver this dynamic lesson.
