How the Planetarium Works

With the completion of the most recent planetarium renovation, how our system works is considerably different than anytime in the previous fifty years. The Uniview all-dome digital projection system uses a powerful computer to generate interactive images of the night sky and objects in it. Drawing on the Digital Universe Atlas, the image generator of the Uniview system can place the viewer anywhere from the surface of the earth, out to the edge of the known Universe. These are not make-believe journeys, but are based on the most current and accurate data sets available of the known Universe.

Once generated, these images are distorted in a way that makes them look like 3D images when projected onto the dome overhead. With corrected geometry, the sense of motion is very real and you can almost believe that you are flying to another planet or to a distant part of the Universe. Planetary images are based on NASA/JPL planetary images and are highly accurate and realistic. Projection grids, used by astronomers, help to explain complex motions of the sky and objects that we see in it. Phases of the Moon, changes in the seasons, what we see and when, and what the Universe looked like when it was young are all possible.

These immersive films place you at the center of the action, as stars explode around you, and galaxies swirl about. The sense of motion and depth can be overwhelming, exciting, and beautiful.

Future programs will include non-astronomy topics such as the origins of life on earth, chemistry, and other topics. This makes the "planetarium" and environment for much more than astronomy.
