Uncover the Secrets of the Universe Hidden at Wavelengths beyond Our Optical Gaze William Herschel's discovery of infrared light in 1800 led to the development of astronomy at wavelengths other than the optical. Infrared Astronomy - Seeing the Heat: from William Herschel to the Herschel Space Observatory explores the work in astronomy that relies on observations in the infrared. Author David L. Clements, a distinguished academic and science fiction writer, delves into how the universe works, from the planets in our own Solar System to the universe as a whole. The book first presents the major telescopes in the world of observational infrared astronomy, explains how infrared light is detected through various kinds of telescopes, and describes practical problems that send infrared astronomers to the tops of mountains and their telescopes into orbit and beyond. Much of the book focuses on what infrared astronomers find in their observations. You'll discover what infrared astronomy reveals about the planets, moons, and other bodies that constitute our Solar System; star formation and stellar evolution; the processes that shape galaxies; and dark energy and dark matter. Infrared astronomy has revolutionized our understanding of the universe and has become essential in studying cosmology. Accessible to amateur astronomers, this book presents an overview of the science and technology associated with infrared astronomy. With color figures, it shows you how infrared astronomy provides insights into the workings of the universe that are unavailable at other wavelengths.

The ESO jIAC Workshop on Quasar Hosts was held in Puerto de la Cruz, Tenerife, from 24 to 27 September 1996 in the Conference Centre of the Ca- bildo Insular de Tenerife. The four days of the meeting were filled with fasci- nating new results and interesting discussions, and ranged from the centre of our own galaxy to some of the most distant objects known in the universe. Quasar Host studies are going through an exciting time, and are benefiting from new facilities, including the refurbished HST and the Keck, and from novel techniques, including adaptive optics and deconvolution methods. We also saw the first of hopefully many results from the ISO satellite. These re- sults were presented during the many sessions and discussed in the gardens over coffee, and on the bus during our tour of the Canaries Observatories. We would very much like to thank the secretaries of ESO and lAC, Christina Stoffer, Pamela Bristow, Monica Murphy, Judith de Araoz, and Beatriz Mederos, who we depended on for their expertise and efficiency. Our colleagues on the scientific organising committee, Phil Crane, Bob Fosbury, Marie-Helene Ulrich, Peter Shaver and Jose Rodriguez-Espinosa, deserve considerable thanks for their contributions to the programme. We must also thank the local organising committee, Fernando Cabrera- Guerra, Monica Murphy, Ismael Perez-Fournon, Ana Perez-Garcia, Luis Ramirez-Castro, and Montserrat Villar-Martin, for all their efforts in making sure things ran smoothly on the day.
