An atmosphere starry sky light for festival entertainment is provided. The constellation unit is configured to switch patterns of twelve constellations and perform projection display on the patterns of the twelve constellations. The starry sky unit is configured to project a starry sky background. The background unit is configured to project patterns of aurora, clouds, and ripples. The planetary unit is configured to switch patterns of a planet, and to project and display a planetary image. The constellation unit, the planetary unit, the starry sky unit and the background unit form a panoramic image of the cosmic starry sky by superimposing and combining.

An educational monument, comprising a designated geographical area accessible to a general public, a first structure having a first face positioned to receive a solar light beam, an aperture formed through the first structure for projecting the light beam at predetermined times and, a second structure positioned to receive the light beam at a first predetermined time. A third structure positioned to receive the light beam at a second predetermined time. Wherein a transition of the light beam reflects a change in the seasons and an alignment of Earth illustrating a physical representation of the transition at a plurality of successive predetermined times, each respective predetermined time being the same hour on a different day. Wherein a plurality of ellipses are scaled from the receiving wall, accurately representing the scaled orbit of the planets.
