An Astronomical Life - Observing the Depths of the Universe" Though science as a subject can be di?cult, what has been more important for me is that its practice can also be rewarding fun! This book is crafted to expose the reader to the excitement of modern observational cosmology through the study of galaxy evolution over space and cosmic time. Recent extragalactic research has led to many rapid advances in the ?eld. Even a suitable skeptic of certain pronouncements about the age and structure of the Universe should be pleased with the large steps that have been taken in furthering our understanding of the Universe since the early 1990's. My personal involvement in galaxy research goes back to the 1960's. At that point, galaxies were easily recognized and partially understood as organized c- lections of stars and gas. What their masses were presented a problem, which I supposed would just fade away. But fade it didn't. Distant active nuclei and quasars were discovered in the mid-1960's. A c- mon view of QSOs was that they have large redshifts, but what use are they for cosmology or normal galaxy astrophysics? I shared that conclusion. My expec- tions fell below their potential utility. In short, the Universe of our expectations rarely matches the Universe as it is discovered.

The quest for the farthest objects in the Universe remains one of the most challenging to modern astronomy. Peering deeper and deeper into space reveals the most distant and powerful objects known and so probes back to the embryonic epochs of the Universe not long after its birth in the Big Bang. Four world experts - chosen for their ability to communicate research astronomy to popular audiences - each contribute a chapter to this lucid survey, first published in 1994. In clear terms they bring to the general audience the excitement and challenge of studying the Universe on the largest scales. They address the fundamental issues of scale in the Universe; the ghostly etchings seen on the cosmic background radiation; quasars and their evolution; and galaxy birth. This survey offers an exceptional chance for the general audience to share in the excitement of today's forefront research of the early Universe in an accessible and stimulating way.
The quest for the farthest objects in the Universe remains one of the most challenging areas of modern astronomical research. Peering deeper and deeper into space reveals the most distant and powerful objects known and so unveils the embryonic epochs of the Universe not long after its birth in the Big Bang. Four world experts--chosen for their ability to communicate research astronomy at a popular level--each contributes a chapter to this lucid survey. They address the fundamental issues of scale in the Universe; the ghostly etchings seen on the cosmic background radiation; quasars and their evolution; and galaxy birth. This fascinating and accessible account offers an exceptional chance for the general audience to share in the excitement of today's forefront research of the early Universe.
