Description: Constellations are groups of stars that form imaginary shapes in the night sky. However the constellations only appear in that specific shape because we are viewing them from one location in the Universe. In this short video common constellations are toured in 3D showing varied shapes depending on the perspective of the viewer. Students can observe this phenomenon using the Interactive 3D Map of the Universe. The brightness of a star depends on the type, size, and distance from Earth.
