A Companion to Astronomy and Astrophysics:

The story of science is one of individuals, as well as discoveries and ideas. So our Timeline includes the people who have made major scientific contributions that are related to astronomy, and astrophysics.

The Dictionary defines all terms and acronyms that deal with our celestial science, from important concepts to individual objects and space missions. It is arranged alphabetically and complemented by numerous tables of fundamental data for bright cosmic objects, including the celestial coordinates required to observe them. Line drawings are also used to forcefully compact a scientific insight, with clear labels and captions.

An exceptionally thorough Index cross-references concepts, discoveries and individuals in both the Timeline and Dictionary. The combined result is a unique, comprehensive, stand-alone reference volume in which the reader can quickly locate information, while also discovering new and unexpected knowledge. Astronomy and Astrophysics is therefore an indispensable book for any library and all persons interested in astronomy and astrophysics, as well as the related fields of cosmology, geology and physics.
