Constellations are simply groups of stars that form patterns in the night sky. Ancient peoples saw these patterns in the stars as representations of their cultures’ stories and myths. Ancient farmers used constellations as a calendar to tell what month it was. This was very useful for planning their planting and harvest. Sailors used their knowledge of constellations to help with navigation.
These patterns in the sky weren’t just useful for ancient peoples. They still serve as guides for modern man. In 1922, the International Astronomical Union (IAU) officially defined 88 constellations. These constellations help astronomers communicate about the areas of the sky they are studying.
● paper towel roll
● aluminum foil cut in 4-inch squares
● a Sharpie
● a toothpick
● Constellation guide, sky map, or space app for your device
Trace the outline of the paper roll on the middle of a piece of foil. Then, draw your favorite constellation on the center of the outlined circle.
Wrap the foil around the end of the paper roll with the constellation markings facing out. Using a toothpick, carefully poke holes in the foil where the stars of the constellation are marked.
Aim your viewer at a light source and look into the open end. You should see your constellation!
