The San Juan College Planetarium’s AstroFriday presentation for Friday, September 29, is Cosmic Castaways. Show times are at 6:30 and 7:30 p.m.
This 20-minute full-dome planetarium show focuses on galaxies and their stars. Most stars lie within the crowded boundaries of galaxies, traveling with their brothers and sisters in a vast galactic family. Some find themselves on their own, deep within voids between the galaxies – these are the cosmic castaways.
The full-dome presentation will be followed by a live guided tour of the sky, using the Planetarium’s Digitarium Zeta star projector.
Fall sky maps will be given out while supplies last. There is no admission charge, but there is a maximum seating capacity of 60 in the Planetarium, so seating will be on a first-come, first-served basis. In order to preserve dark-adaption, no one will be admitted late once the show has started.
Due to construction of the West Classroom Complex, entrance and exit to the Planetarium is through the outside door from the courtyard between the Planetarium and the Little Theatre.
Weather permitting, a free public stargaze with telescopes will be held at 8:30 p.m. in the courtyard between the Planetarium and the Little Theatre, after the last show. The Stargaze will last a maximum of one hour.
There is no capacity limit for the stargaze. Plan to view the waxing gibbous Moon and the spectacular planet Saturn. More challenging solar system targets include the distant gas giants Neptune and Uranus. Binary star targets for the evening feature the always spectacular double star, Albireo. If weather conditions are particularly favorable, participants may also see such deep-sky objects as the Ring Nebula in Lyra, the globular cluster M13 in Hercules, the Wild Duck Cluster in Aquila, and the Dumbbell Nebula M27 in Cygnus.
