The galactic and extragalactic background radiation components are of major importance in astrophysical studies of a variety of problems related to galactic structure, interstellar matter, the distribution and evolution of galaxies and intergalactic matter, and cosmology. The back ground radiation is a unique source of information in cases where the source is of a truly diffuse nature, as with scattering and emission by interstellar dust and gas, or where the discrete emission sources are so faint (e. g. , very distant galaxies) that they can be observed only by their integrated emission. The galactic and extragalactic background must be discussed together because they are observationally entangled and their proper separation requires a knowledge of both components. The above points are equally valid for the entire electromag netic spectrum, from gamma rays to long radio waves. Thus, the study of the galactic and extragalactic background radiation is interdisciplinary in its character, and a multi wavelength approach would appear to be dictated by the nature of the topic. The proper separation of the galactic and extragalactic background components requires a knowledge of both. In addition, the foreground components, i. e. , zodiacal light, airglow, and atmospheric scattered light, must be treated carefully.

Cosmology has not been the subject matter of a Saas-Fee Advanced Course since 1978. That occasion was the memorable course entitled Observational Cosmologyy with lecturers J.E. Gunn, M.S. Longair, and M.J. Rees. A new course on cosmology seemed overdue, and we subsequently planned and or ganized, with the endorsement of the Swiss Society of Astrophysics and As tronomy, the present, 23"^^ Saas-Fee Advanced Course. Probing (drilling) the Universe to greatest depths, in terms of diffuse radiation and discrete objects, with all consequences for our understanding of cosmic evolution, was meant to be the unifying aspect of this course. Hence the title The Deep Universe. We are very happy to have won such competent and brilliant scientists as lecturers. Malcolm Longair - Saas-Fee lecturer for the second time! - lectured on cosmological background radiation ("The Physics of Background Radia tion"); Richard Kron on observations of extremely distant galaxies ("Evo lution in the Galaxy Population"); while the Grand Master of Cosmology, Allan Sandage, provided the fundaments of it all, also in a historical sense ("Practical Cosmology: Inventing the Past"). The course took place from 29 March to 3 April, 1993, in Les Diablerets, with around 90 participants. The format was as usual, every lecturer giving 9 or 10 lectures of 45 minutes.

What is the future of observational astronomy? The effect on astronomy of environmental degradation, from electromagnetic pollution to near-Earth space debris, and the broader implications of jeopardising this science are explored in this provoking review. Astronomy is acutely vulnerable to environmental pollution. This survey demonstrates, unequivocally, the destructive impact of civilisation on current observational astronomy and its future. International astronomers discuss the source and effect of electromagnetic pollution - from optical to radio wavelengths - and space debris. Together with specialists from industry, law and elsewhere, they go on to outline possible remedies and the legislation required for successful international regulation of the pollutants. These articles offer an authoritative survey of the pollutants and the steps necessary to regulate them. They provide an essential reference for the professional astronomer, environmentalist and concerned non-specialist.

Space experiments have opened practically all electromagnetic windows on the Universe. A discussion of the most important results obtained with multi-frequency photonic astrophysics experiments will provide new input to advance our knowledge of physics, very often in its more extreme conditions. A multitude of high quality data across the whole electromagnetic spectrum came at the scientific community's disposal a few years after the beginning of the Space Era. With these data we are attempting to explain the physics governing the Universe and its origin, which continues to be a matter of the greatest curiosity for humanity. In this book we describe the latest steps of the investigations born with the advent of space experiments. We highlight the most important results, identify unsolved problems, and comment on perspectives we can reasonably expect. This book aims to provide a useful tool for the reader who is not specialized in space astrophysics and for students. Therefore, the book is written in the form of a review with a still reasonable length, taking into account the complexity of the arguments discussed. We do not claim to present a complete picture of the physics governing the Universe, but have rather selected particular topics for a more thorough discussion. A cross section of essays on historical, modern, and philosophical topics is offered and combined with personal views into tricks of the space astrophysics trade.

Over the last decade, statisticians have developed new statistical tools in the field of spatial point processes. At the same time, observational efforts have yielded a huge amount of new cosmological data to analyze. Although the main tools in astronomy for comparing theoretical results with observation are statistical, in recent years, cosmologis
