How galaxies � and yet larger structures � are formed remains one of the most interesting, topical and important questions facing astrophysicists and cosmologists today. This fully updated and revised edition of The Road to Galaxy Formation draws on the most recent observation of galaxies in the early universe obtained by the very latest ground- and space-based telescopes.
The study of the formation and early evolution of stars has been an ever
growing part of astrophysical research. Traditionally, often in the shadow of
its big brothers (i.e., the study of stellar structure, stellar atmospheres and
the structure of galaxies), it has become evident that early stellar evolution
research contributes essentially to these classical fields. There are a few new
items on the list of traditional astrophysical studies, some of which are more
related to features known from the extreme late stages of stellar evolution.
Water is one of the basic elements for life. It is even assumed that the evolution
of life is only possible if there is liquid water present. A water molecule has some
remarkable properties that make it quite unique in the universe. In the first chapter
of this book we will review these basic properties of water and the role of water on
Earth. All ancient civilizations realized the importance of water and their cities were
constructed near great reservoirs of water.
