Abstract: A body portion of non-luminous material has an enlarged surface area on which design elements are applied of luminous material. The design elements are shaped to depict celestial bodies and the arrangement is such that when these design portions are charged by light, they will glow in the dark so that in an overhead position a nocturnal celestial appearance is provided. The body portion can consist of a double layer of material and the design elements confined between the two layers. A support for the body portion may include an electric motor for rotating the body portion to simulate rotation of the earth.
