The Universe investigates the scientific origins of the moon, asking how it came to be. The answer is more astounding and spectacular than most residents of earth have ever imagined. For thousands of years, mankind has found comfort in its presence. It has been a lantern for nocturnal travellers, a timekeeper for farmer and a location finder for sailors at sea. For some cultures, it has even been a god. It is also the only cosmic body ever visited by human beings.
