From the beginning of time, human beings have looked up at the stars and speculated on other worlds. We have written endless stories, stared for hours through telescopes, made observations, calculations, and finally, started to understand how these celestial bodies influence our world. This is the story of the sun and the moon. It is also the story of human history. This collection of origin stories from different cultures, scientific discoveries, facts and observations uncovers what we really know about Earth's most influential companions. Beautifully illustrated, the book works in two parts - one side is dark, but flip it over and the other is bright, meeting in the middle in a perfect eclipse.
