Humans have long thought that planetary systems similar to our own should exist around stars other than the Sun, yet the search for planets outside our Solar System has had a dismal history of discoveries that could not be confirmed. However, this all changed in 1995, after which astonishing progress can be seen in this field; we now know of more than 200 extrasolar planets. These findings mark crucial milestones in the search for extraterrestrial life arguably one of the most intriguing endeavors of modern science. These proceedings from the 2005 Space Telescope Science Institute Symposium...

This book acknowledges the importance of identifying the most crucial science to be performed by the superb Hubble Telescope. With this goal in mind, the book presents a review of some of the most important open questions in astronomy. World experts examine topics ranging from extrasolar planets and star formation to supermassive black holes and the reionization of the universe. Special emphasis is placed on what astronomical observations should be carried out during the next few years to enable breakthroughs in our understanding of a complex and dynamic universe. In particular, the reviewers...

The Hubble Deep Field (HDF) is the deepest optical image of the Universe ever obtained. It provides a unique resource for researchers studying the formation and evolution of stars and galaxies. This volume provides a comprehensive overview of the scientific impact of the HDF on cosmology. It presents articles by a host of world experts who gathered together at an international conference at the Space Telescope Science Institute. The HDF is set to revolutionize our understanding in cosmology. This book combines both observations of the HDF at a variety of wavelengths with the latest...

The Local Group of galaxies consists of the Milky Way and all of its neighbors. The proximity of these galaxies allows for detailed studies of the processes that have led to their formation, structures, and evolution. In particular, studies of the Local Group can test predictions of structure formation that are based on dark energy and cold dark matter. This book presents a collection of review papers, written by world experts, on some of the most important aspects of Local Group Astrophysics. It is an invaluable resource for both professional researchers and graduate students in this...
