Astronomy is a user-friendly guide for beginners. Chapters make it easy for you to quickly learn the main topics of a college level course. Sections clarify basic principles and contemporary advances. The Index enables you to look up concepts, definitions, facts and famous astronomers, fast. You can use the book alone or with a conventional textbook, Internet based or distance-learning course, computer software, telescope manual, or as a handy reference.
A list of objectives for each chapter tells you instantly what information is contained there. The first time a new term is introduced, it appears in bold type and is defined. Topics in each chapter are presented in short, numbered sections. Each section contains new information and usually asks you to answer a question or asks you to suggest an explanation, analyze, or summarize as you go along. You will always see the answer to the question right after you have answered it. If your answer agrees with the book’s, you understand the material and are ready to proceed to the next section. If it does not, you should review some previous sections to make sure you understand the material before you proceed.
A self-test at the end of each chapter lets you find out fast how well you understand the material in the chapter. You may test yourself right after completing a chapter, or you might take a break and then take the self-test as a review before beginning a new chapter. Compare your answers with the book’s. If your answers do not agree with the printed ones, review the appropriate sections (listed next to each answer).
On a clear night in a place where the sky is really dark, you can see about 2000 stars with your unaided eye.
