Today's astronomy students not only seek an up-to-date summary of astronomical facts: they ask, as people have asked for ages, about our basic relations to the rest of the universe. They may study astronomy partly to seek points of contact between science and other human endeavors: philosophy, history, politics, environmental action, even the arts and religion.
Science fiction writers and special effect artists on recent films help today's students realize that unseen worlds of space are real places—not abstract concepts. Today's students are citizens of a more real, more vast cosmos than conceptualized by students of a decade ago.
In designing this edition, the Wadsworh editors and I have tried to respond to these developments. Rather than jumping at the start into murky waters of cosmology, I have begun with the viewpoint of ancient people on Earth and worked outward across the universe. This method of organization automatically (if loosely) reflects the order of humanity's discoveries about astronomy and provides a unifying theme of increasing distance and scale.
