Books by Thomas Hockey

Have you ever wondered what comets are and why astronomers spend so much time studying them? A comet expert and an astronomical historian have come together to produce this unique book. The authors concisely present the information you need to comprehend these majestic apparitions that grace our night skies.

Today's casual observer knows far less about the sky than did our ancestors, who depended on the sun and the moon to tell them the time and on the stars to guide them through the seas. This title gives us back our knowledge of the sky, offering an overview of what can be seen there without the help of a telescope.
