Prepare for the holiday season once again at Marietta College's Anderson Hancock Planetarium with the full-dome show "Season of Light," at 7:00 p.m., Thursday, December 19th. "Season of Light" traces the history and development of numerous holiday traditions, including the Yule log, mistletoe, and the Christmas tree. The program concludes by exploring possible astronomical explanations for the Christmas star. Preceding Season of Light will be a brief star talk focusing on the late December sky. Season of Light was created by Loch Ness Productions.
