Lynn Poole introduces the program by pointing an arrow gun, or optical pointer that is used to point to objects on the dome of a planetarium. Man has wondered about the universe around him since prehistoric times, noticing the movement of the stars and planets. Early in the 20th century the Zeiss planetarium was developed and built in six cities in the United States. After World War II, Armand Spitz produced the Spitz planetarium which made it much more economical for smaller sites to have planetariums. There are now over one hundred in the United States. Mr. Spitz discusses how these planetariums work. He has also designed a toy planetarium that can project images of the stars and planets in the home.

The program begins with a discussion of the solar system with the sun in the center and the nine planets, with their satellites or moons. Comets also travel around the sun in very irregular orbits. Great clusters of billions of stars form galaxies. The earth is near the center of the galaxy known as the Milky Way. Stars are arranged into the constellations that have distinctive configurations.
