The Christa McAuliffe Center at Framingham State University opens its planetarium for free public presentations each month (except April), with new topics each month within one of three series:  Family Night, Late Nite Skies, and Stellar Nursery. This month’s Family Night film, Holiday Skies, will be shown on December 13 at 5:30PM and 6:30PM for families with children 6 years or older. Register now at those links because space is limited, and for guaranteed seating you must pre-register and arrive 15 minutes before show time (directions and parking). A suggested donation of $5 per guest is requested. For more information, email cmc@framingham.edu.
