ABSTRACT:
Disclosed is an enclosed planetarium with both fluorescent and phosphorescent painted representations of astronomical bodies, some of the representations may be mobile and rotated and the remainder of the representations may be painted on the inside surface of the enclosure. An ultraviolet light source is provided which upon activation illuminates all of the representations, but upon extinguishment only the phosphorescent painted representations continue to be visible. This provides two different displays both of which have the pleasing effect of ultraviolet illumination.
