The Montgomery College 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.
Dr. Harold Alden Williams, Planetarium Director
Dr. Harold Williams has been the director of the Montgomery College Planetarium since 1990. He is also the coordinator of the Physics labs and the head of the Astronomy program.
Originally from Jacksonville, FL, Dr. Williams received his Bachelor of Science degree with a double major in physics and mathematics from Florida State University. He received his Master of Science from the State University of New York at Stony Brook and his doctorate from Louisiana State University—where he studied star formation by using 3D explicit Eulerian hydrodynamics. At LSU, Dr. Williams first started teaching astronomy and learning how to use telescopes and run a planetarium. Dr. Williams continued his star formation studies for two years after leaving LSU as a post-doctoral fellow at the Department of Terrestrial Magnetism of the Carnegie Institution of Washington.
In 1993, Dr. Williams co-wrote a proposal that secured funding from the National Science Foundation to allow Montgomery College's campuses to be connected to the internet. He has secured hundreds of thousands of dollars in grants during his tenure and works tirelessly to improve the Physics program and expand the Planetarium's offerings. Dr. Williams has developed numerous educational programs for the Planetarium, including grade-specific programs for local school field trips. He is also the faculty adviser to the Science Club.
Dr. Williams is currently president of the National Capital Astronomers, which is affiliated with the National Academy of Sciences. He was also president from 1996-1998 and 2005-2007, and vice president/program chairman from 1994-1996. He also worked with the Goddard Space Flight Center as a High Energy Spectroscopic Imager (HESSI) education partner.
When he is not running the Planetarium, Dr. Williams teaches astronomy and physics courses and represents Montgomery College at events and conferences abroad. His current scientific preoccupation is to one day fully understand how angular momentum is redistributed through star formation.
SciDome XD Projector
The Planetarium uses a state of the art Spitz SciDome XD projector that can do far more than just show the night sky and a few constellations. Students and visitors can see astronomical objects from the perspective of anywhere in the universe, view 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 Planetarium also produces its own 3D video and full dome presentations.
From I-495, the capital beltway, go south on George Avenue (Route 97). Turn left on Sligo Avenue. Continue to Fenton Street; turn right. The parking garage will be on the right on King Street between two storage facilities. To reach the Planetarium, continue on Fenton and keep right through the next stop sign after the garage. The Planetarium will be on your left. The campus is easily accessible from the Silver Spring and Takoma Park Metro stations and local Ride-On buses as well.
Parking While Visiting the Planetarium
You cannot park in the lot directly adjacent to the Planetarium as this is for Faculty and Staff only and requires a permit. If you do not have a Montgomery College parking permit of any kind, there are multiple public metered parking spaces around campus. You can also obtain a visitor permit if you are attending an event that will allow you to park in the garage on King Street by first stopping at the Planetarium before parking. You may park briefly in the lot outside the Planetarium to go inside and obtain your permit.
If you are coming to a grade-specific field trip and traveling in a school bus, please pull the bus adjacent to the planetarium in the faculty/staff parking lot outside the Planetarium. There is a wide area outside the Planetarium where you can load and unload.
