A must have volume for any astronomer, this fourth edition has grown to more than twice the size of the previous editions in order to accommodate all the more recent developments in astronomy and astrophysics.
This reference is a compilation of the work of over ninety authors who worked over nine years. Recent advances in astrophysics and astronomical observations have provided a new understanding and an enormous amount of new data about our solar system, galaxies, galaxy clusters, and their emissions. New or greatly expanded chapters provide detailed tables of the most recent data covering the topics of radio, infrared, ultraviolet, X-ray, and gamma-ray and neutrino astronomy; stellar evolution; and cosmology.
Several chapters are also devoted to the general constants and units; atoms, molecules and spectra; observational and planetary astronomy; supernovae; stellar populations; and star clusters and quasars.
