To study astronomy is to consider the most wondrous phenomena on the grandest of scales - the universe and all it contains. Beginning with our earliest explorations of the night sky, William Waller takes us on an enthralling journey through the Milky Way and far, far beyond. He combines science and history to show how our understanding of everything from black holes to the structure of the universe has evolved over time, illuminating past discoveries and offering contemporary insights into the cosmic histories of stars, planets and galaxies. Whether object of study or curiosity, the universe - and all it contains - is tantalisingly introduced here.
