This book is designed for upper division courses in astronomy and as a reference for science professionals. The subject areas of astronomy and astrophysics have grown tremendously during the last few decades. New developments in radio astronomy and recent data retrieved from NASA's Hubble Space Telescope have resulted in many discoveries and created new interest in the study of the universe. Using four-color throughout, Astronomy & Astrophysics describes the different techniques and instruments employed in the study of the universe and the results obtained with discussion on both theory and observation. The book covers topics such as, "minor" planets, radio astronomy, astronomical telescopes, measurement of solar brightness distribution, black holes, and the Einstein effect. A CD-ROM with color figures and simulations accompanies the book.
