Planetarium: Light Years from Andromeda
A beam of light leaves the Andromeda Galaxy and travels across intergalactic space. On a nearby planet, intelligent life evolves. As the light speeds across the light years, the primitives on the planet form cultures and civilizations — and begin to wonder about the universe surrounding them. When the light reaches Earth, some of the descendants of the early hunters have just escaped the bonds of their world’s gravity, and visited the Moon.
