About The Planetarium

Within The York Learning Center Planetarium, one is able to observe celestial motions that, in some instances, would take years of 'real-time' observation. Additional capabilities, such as dynamic illustrations of astronomical phenomena, help to make astronomy so intriguing that one cannot help but get excited and want to learn more.

The Spitz planetarium projector below is housed under a 30 foot dome with theater seating for 56 people (The planetarium is wheelchair-accessible.) This projector can display thousands of stars in both the northern and southern hemispheres, the sun, moon, visible planets, and the Milky Way. A celestial coordinate system, ecliptic, and meridian projectors complement the main projector to allow, among other things, accurate sky measurements. Take a trip into the future or back into time.

Who Can Use the Planetarium?

We offer programs for the public of all ages as well as for Scouts, students in preschool through senior high school, and other groups. If you plan to come as a group of more than10, we strongly recommended making reservations as these shows are often full. We are fully accessible for guests with limited mobility.

Why Visit the Planetarium?

The planetarium is a unique educational and entertaining experience. See the night sky the way it was before light pollution erased most of the stars from view. Learn how to find your way around the night sky. Watch one of the special shows presented as seen only at a planetarium. If weather permits, look through one of the YCAS members telescopes set up for seeing the planets or Moon after the show.

Can we have a Private Show?

Private shows are available. For pricing information please contact planetarium director Todd Ullery. See Contact planetarium link. Contact Planetarium
