Join us as we explore space! T.C. Williams opens up its doors to the Alexandria Community one night of every month during the school year for a free hour-long show designed to bring the mysteries of the Universe down to Earth.

The Planetarium at T.C. Williams is a valuable resource that supports students' ability to learn and understand science and is committed to high quality astronomy and space science education services by providing outreach programs to students, families and the community. Programs offered through the Planetarium's Community Nights are intended to create an awareness of the cosmos, encourage creative thinking and inspire the next generation of explorers!
