The Texas A&M-Commerce Planetarium will be holding its annual Christmas programming along with a tour of the night sky tonight. “Let it Snow” will play at 7:00 pm, combining traditional Christmas and an exciting finale featuring the Trans-Siberian Orchestra. The show will have computer-animated videos synced to the music. The next part, starting at 8:15 pm, will blast you back 2000 years in search of a scientific explanation for the Star of Bethlehem. Opening at 6:30 pm, the ticket office will have tickets available for $5 a person for each show.
