NASA's James Webb Space Telescope (JWST), planned for operation in about five years, will have the capability to investigate - and answer - some of the most challenging questions in astronomy. Although motivated and designed to study the very early Universe, the performance of the observatory's instruments over a very wide wavelength range will allow the world's scientific community unequaled ability to study cosmic phenomena as diverse as small bodies in the Solar System and the formation of galaxies. As part of preparation to use JWST, a conference was held in Tucson, Arizona in 2007 that brought together astronomers from around the world to discuss the mission, other major facilities that will operate in the coming decade, and major scientific goals for them. This book is a compilation of those presentations by some of the leading researchers from all branches of astronomy. This book also includes a "pre-history" of JWST, describing the lengthy process and some of the key individuals that initiated early work on the concepts that would evolve to become the premier space observatory of the next decade.

Thronson's current responsibilities include identification, assessment, and advocacy for advanced human/robotic programs at NASA Goddard Space Flight Center in coordination with other NASA Centers, industry, and the scientific community. Previously, while working at NASA Headquarters, he was responsible for selection and development of advanced technologies that will significantly enhance future science missions such as large astronomical observatories in space and robotic missions to Mars, other planets, and the Moon. He has also served as the program scientist for the Hubble Space Telescope (HST), the Spitzer Space Telescope (SIRTF), the James Webb Space Telescope (JWST), and the Stratospheric Observatory for Infrared Astronomy (SOFIA), among other missions. Over the past few years, he has served as senior scientist on a variety of long-range planning activities and led three NASA HQ teams that developed science and technology priorities for President George Bush's Vision for Space Exploration. He received his Ph.D. in astrophysics in 1978 from the University of Chicago and has been a faculty member and on the senior staff of the Universities of Arizona and Wyoming, and the Royal Observatory, Edinburgh. He has published more than 100 research papers and co-edited 12 books.

Stiavelli obtained his PhD at the Scuola Normale Superiore of Pisa in 1986. He has been a postdoctoral researcher at Rutgers University and a fellow at the European Southern Observatory in Garching. He has held positions at the Scuola Normale Superiore of Pisa (1992-1995), at the European Space Agency in Baltimore (1995-2000), and at the Space Telescope Science Institute in Baltimore (since 2000).  He is a member of the American Astronomical Society, of the American Association for the Advancement of Science, of the American Institute of Aeronautics and Astronautics and of the International Astronomical Union. He hasserved and chaired several NASA committees and is a member of the Science Working Group of the James Webb Space Telescope. He has authored or coauthored 83 papers on professional journals and 146 technical reports and other publications.

Tielens is a senior scientist at NASA Ames Research Center and a professor of astrophysics at the Kapteyn Institute in the Netherlands. Prior to this, he was associated with the astronomy department of the University of California in Berkeley and the Dutch Space Agency, SRON. He is the project scientist of HIFI the heterodyne instrument that will fly on the Herschel Space Observatory and the coordinator of the 'Molecular Universe' an interdisciplinary network on interstellar chemistry. He has published extensively on various aspects of the physics and chemistry of the interstellar medium of galaxies.
