Bücher von Donald E. Osterbrock

Walter Baade was an influential observational astronomer of the twentieth century. This biography of this major figure in American astronomy suggests that Baade's greatest contribution to astrophysics was his discovery of two distinct stellar populations: old and young stars.

This is the biography of James E. Keeler (1857-1900), a distinguished pioneer of astrophysics, the application of the methods of physics to understanding the nature of the stars, nebulae, planets, comets, and other objects that populate the universe.
