How do astronomers know what they know about the stars and planets? That is the question behind today''s rapid pace of cosmic discovery, for every new finding rests upon a centuries-long foundation of astronomical practice. Introduction to Stars and Planets: An activities-based exploration reveals the methods by which Earthbound observers have deduced the physical attributes of celestial bodies, whether situated within our solar neighborhood or at the far ends of the galaxy. The book''s 28 mildly mathematical activities invite readers to carry out the essential work of the astronomer by utilizing real observational data sets and high-quality celestial photographs to establish the innate properties of a range of cosmic systems. Taken in sequence, these activities illustrate the epic advancement of stellar and planetary astronomy over the past century, up to the present day.Key FeaturesWide-ranging topical coverage of both historical and up-to-the-minute aspects of astronomical discoveryUses a learning-by-doing approachStructured, goal-oriented framework centered on the methods and physical principles by which astronomers study the universeProvides real-time educational feedback to studentsIntroduces elementary mathematics for students to gain a truer sense of the work astronomers do
