The observable universe beyond the thin slice of the visible spectrum is often overlooked. The Radio Sky Cylinder immerses the audience in the radio universe, yielding a firsthand experience with a part of the electromagnetic spectrum of which most are unaware. The program consists of a radio view of the sky projected on the portable planetarium dome which can be removed and replaced with the visible sky view of the Milky Way. Newspapers and magazines, television and the internet, broadcast almost daily, news about discoveries in astronomy that have been made at radio, millimeter, infrared, ultraviolet, x-ray, and gamma-ray wavelengths. This cylinder can help students relate to these discoveries and become excited about them. For middle and high school students, this cylinder is accompanied by a 16- page curriculum with background information, a cylinder script and activities.
