A basic guide to the latest news from the cosmic frontierabout the black holes in the centers of galaxies, about the way in which some galaxies cannibalize each other, about the vast distances between galaxies, and about the remarkable new evidence regarding dark energy and the cosmic expansionthis book gives us a firm foundation for exploring the more speculative fringes of our current understanding. This is a heavily revised and completely updated version of Hodges Galaxies, which won an Association of American Publishers PROSE Award for Best Science Book of the Year in 1986.
