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 generate energy. The life histories of stars, from origin through final demise, sometimes through variability to beautiful nebulae, sometimes via violent explosions as supernovae, is recounted in detail. The exotic life histories of many double stars, some of which produce novae, are also described, and the origins of chemical elements in dense stellar cores and the vital role played by gas and dust between the stars is explained. The book closes with an account of the exciting new field of high-energy astronomy and the origin of cosmic rays. This is the ideal introduction to the important field of modern astrophysics for physics and astronomy students. It should also appeal to amateur astronomers interested in the life history of a star, be it a modest one such as our sun or a massive object destined to become a supernovae.

Astronomer university professor
He was born in Tacoma, Washington.
He never finished high school and worked for a time as a gold miner. There he obtained his master"s degree in 1938 and his Doctor of Philosophy in 1943.
He received his bachelor"s degree from the University of California, Berkeley in 1936 and went to graduate school at Harvard in 1937. From 1943 to 1945 he worked on the Manhattan Project at the University of California Radiation Laboratory. He was an assistant professor at Indiana University from 1945 to 1948 and then an associate professor and professor at the University of Michigan until 1962.
He moved to University of California, Los Angeles in 1962 and helped build its astronomy department.
He was chair of the department from 1963 to 1968. His work concentrated on the chemical composition of stars and nebulae.
He was one of the first astronomers to argue that some differences in stellar and nebular spectra were caused by differences in their chemical composition. Aller wrote a number of books, including Atoms, Stars, and Nebulae, the third edition of which was published in 1991 ().
He published 346 research papers between 1935 and 2004.
He was elected to the American Academy of Arts and Sciences in 1961 and to the United States National Academy of Sciences in 1962.
