MC Planetarium

Welcome to the Montgomery College Planetarium

The Planetarium is located on the Takoma Park/Silver Spring Campus and is an extension of the Science South Building. The facility is both the centerpiece of the Astronomy program and the local planetarium for the surrounding neighborhood. 

The Planetarium has a 24-foot dome and uses a state of the art Spitz SciDome XD projector that can show astronomical objects from the perspective of anywhere in the universe, show star positions up to 100,000 years in the past or future, and use Layer Earth to study our own planet's geology, geography, and atmosphere. The projector can also show full 360 video using the entire dome to create an unbelievably immersive experience. The facility has a large video monitor at eye level with 3D capabilities for special presentations and educational videos.

The Planetarium has regular events, including lectures and light shows, and often hosts star gazing parties for dazzling astronomical occurrences like meteor showers, eclipses, and comets. Visitors can observe what are often once in a lifetime celestial spectacles through either of the Planetarium's two telescopes; a 13 inch Dobsonian and a 3 1/2 inch Questar. Most events are free and open to the public. Check out the event calendar to find out about upcoming shows and lectures.
