Book excerpt: Most of the constellations, the patterns of stars found in the night sky, are connected with the ancient myths which people developed to give meaning to what they saw in the sky, based on the experience of their culture. The ideas of modern astronomy play a similar role for us today. They are stories which help us understand the phenomena we discover when we look deeper into the sky than is possible with eyes alone. In this book, the ancient sky stories and those of modern astronomy are woven together in a unique way. Coverage includes twenty-four important constellations as well as the sun and the moon and the sky as a whole. For each of these, one of the old stories is tied together with the astronomical understanding of a key feature in that part of the sky, allowing one story to serve as a reminder for the other.
