In 75 essays, Evans supplies fascinating facts and raises questions about the mysteries of astronomy. Why is the night sky dark? How likely is it that meteors killed the dinosaurs? Since Halley's Comet orbits the wrong way around the sun, did it originate outside our solar system? He also encourages the reader to become involved in our cosmic backyard, pointing out that a telescope isn't necessary for most viewing - binoculars are adequate for most sights and are actually better for seeing meteors and some nebulae.
