In a nontechnical fashion, this book tells the story of how astronomy and physics work together to unravel many mysteries of stars and nebulae. Professor Aller's descriptions stress deeper understanding of these objects, not just a mere review of facts. After a succinct, nonmathematical excursion into the principles of radiation and atomic structure, he explains in simple terms the physical processes at work in stars and gaseous nebulae. A survey of masses, dimensions, luminosities, temperatures, and chemical compositions of stars is followed by an exploration of their interiors and how stars...
