Montgomery College's
  Planetarium at Takoma Park, Maryland USA

A picture of the planetarium from Fenton Street. Directions to the planetarium. Exciting public planetarium programs are offered at Montgomery College at Takoma Park . Astronomy is one of the few sciences accessible to any inquiring mind. Astronomy is the oldest science and one of the few sciences that welcomes amateurs. Please come to a public planetarium program and explore the universe with us. Everyone who looks up at the stars with wonder is an astronomer. The planetarium is open from the last week in August until the Friday before Memorial day in May. This is an academic institution so there are a few holidays like Thanksgiving and around Christmas and new year's day when the entire institution is closed.
Special Summer Planetarium Programs, when the planetarium is closed to the public, like teacher workshops and courses for grade school students are also offered.

Transit of Venus across the Disk of the Sun;  no person alive today has seen the Transit of Venus that last occurred on 6th of  December 1882.   There have been only 5 previous transit observed by humans, since the first in 1639.   If it is clear we will observe it from sunrise around 6:00AM until it ends around 7:26AM in the morning from the roof of  the Parking Garage at Fenton and King Street.  If  it is hopelessly cloudy and predicted to continue that way well past the event then we will have a show on the first floor of the Parking Garage where a  wireless Internet connection has been set up to watching web cams of this event some where, where it is not cloudy.   The direct view is best, but either way we will see the event as it happens, come join us.

See Comet Neat Q4 2001 every day for a week as it rises higher in the sky on the roof of the Parking Garage at Fenton and King Street.

Space-time Invariance and Quantum Gravity what significance does using Discrete Numbers (there is a smallest or shortest quantity) versus Real Numbers (where there is no smallest or shortest quantity) to measure length and time have in the observable universe.  Is it time to abandon the Real Numbers in describing space-time?  What are the physical consequences to our freedom to move forward and backward in space, but only forward in time? 
Saturday, 20 March 2004 at 7:00 P.M. The Rites of Spring, the Vernal Equinox the vernal equinox is 6:49UT on March 20, 2004 which is 1:49AM EST on March 20=UT-5hours+0hours for not being on daylight saving time.
Saturday, 14 February 2004 at 7:00 P.M. African Skies
Saturday, 24 January 2004 at 7:00 P.M. How are Stars Born?
Monday, 22 December 2003 at 7:00 P.M. The Day of the Sun's Return, the Winter Solstice the winter solstice is at 7:04 UT December 22 which is 2:04AM (EST=Eastern Standard time) = UT-5hours+0hours for not being on daylight saving time.
Saturday, 15 November 2003 at 7:00 P.M. Astrolabes
Saturday, 8 November 2003 at 6:30 P.M. Moon viewing during a LUNAR ECLIPSE  with a last gasp opportunity to see MARS on the roof of the Parking Garage at Fenton and King Street or a program about "The REAL OCCULT: Lunar &  Solar Eclipses and Asteroid & Stellar Disappearances Sometimes Involving Luna" in the planetarium if it is cloudy.  An early evening lunar eclipse where the shadow of the earth occults the full moon, you can see this at home, but there will be a telescope on the roof to view the moon if it is clear.  It was clear until 8:30PM so we saw the lunar eclipse from the Parking Garage on King and Fenton Street.
Saturday, 18 October 2003 at 7:00 P.M. Polarization Sundials, learn about a type of  sundial that will work when the sun is covered by a cloud and there is no shadow for a sundial gnome or an hour before the sun has risen or an hour after the sun has set  as long as there is a patch of  blue sky in the north.  White clouds depolarize sunlight and hide the information about where the sun is that is encoded in the polarization pattern of the blue sky!
Tuesday, 23 September 2003 at 7:00 P.M. When the Sky Falls the autumnal equinox is at 10:46 (UT=Universal Time) on this date which is 6:46AM (EDT=Easten Day Light Saving Time) = UT-5hour +1hour for daylight savings time.

Mars viewing on the roof of the College Parking Garage at Fenton and King Street at 9 P.M., or a program about Mars in the planetarium if it is cloudy.  On Wednesday, August 27, at 9:51 UT  = 5:51 A.M. EDT, Mars is as close to earth (55,758,006 km or 3.1 light minutes) as it has been since 57,617 BC, when Mars was a little closer (of course don't expect the view to be much better than it is ordinarily every 15 to 17 years).  Mars will be 25.1 arc seconds in diameter on all five opportunities to see it through a telescope on the roof of the College Parking Garage.  At 9 P.M. Mars will be too low in the sky to see from outside the planetarium, but it will be visible from the roof of the Parking Garage a little south of east as it rises higher.  Fortunately the clouds parted and we were able to see Mars 4 out of 5 times.  Only Wednesday did we have to have a show about Mars instead of actually seeing Mars.  While my house a block away had no power for 4 of these days the College had electrical power the entire time.  

The planetarium shows 1,834 naked-eye stars, the Milky Way (the diffuse band of light caused by the disk of our own galaxy), and the five naked eye planets (Mercury, Venus, Mars, Jupiter, and Saturn) under a twenty-four-foot dome with forty-two comfortable chairs.  The planetarium is located on Fenton Street on the Takoma Park campus of Montgomery College.  It is attached to the Science South building on the ground level and has a conspicuous silver colored domed roof. The stars are the province of all of mankind. An  astrophysicist will answer questions about the universe. There is no admission charge for these public planetarium programs.
Monthly Public Planetarium astronomy shows, grade specific shows for school groups, scout and other youth group programs, senior citizen and other adult group programs, monthly music/laser light shows, cultural astronomy shows (Havdalah, Whisper of Creation, Islamic Astronomy, others possible) college astronomy courses, summer teacher workshops, summer youth courses, all from within a planetarium
