Specifically traces the impact of Einstein's ideas on astronomy, including the way we interpret observations of stars and galaxies. Includes comments from principals in important discoveries, illuminating the processes behind these results. Presents many applications of relativity that have not been shown in earlier popular-level books and illustrates how deeply physics permeates the way we interpret many astronomical phenomena. Highlights light-travel delays in cosmic jets, using gravitational lensing to trace cosmic mass distribution. Illustrations employ new and archival data from ground- and space-based observatories.

Written by one of the leading authorities in the field, this is one of the first book's to describe one of today's most important problems in cosmology - the formation of galaxies. The book tackles this great puzzle by discusses the beginnings of the process from cosmological observations and calculations, considers the broad features of galaxies that we need to explain and what we know of their later history. The author compares the competing theories for galaxy formation and considers the progress expected from new generations of powerful telescopes both on earth and in space. An intriguing text on one of today's greatest and most profound puzzles.
