The Vanderbilt museum also has a 238 seat state of the art planetarium which features different shows on weekends and holidays. It is one of the largest and best-equipped in the United States. Shows feature high def NASA imagery from lunar orbiters and other satellites. In addition to its domed theater where Sky shows recreate celestial events, there is also an Observatory with a professional-grade 16-inch Cassegrainian reflecting telescope through which visitors may scan the real sky on clear evenings, or, during the day, watch actual sunspots and solar prominences as transmitted live to a television monitor in the Planetarium lobby.
