Socrates knew all that was known by his contemporaries. But already in the Middle Ages it was becoming difficult for a single man to have a truly encyclopedic view of all human knowledge. It is true that Pico della Mirandola, Pius II, Leonardo da Vinci, and several other great minds were thoroughly in possession of considerable know ledge, and knew all that one could know, except no doubt for some techniques. The encyclopedists of the 18th century had to be content with an admirable survey: they could not go into details, and their work is a collective one, the specialized science of each collaborator compensating for the insufficiencies of the others. We know very well that our science of today is a science of specialists. Not only is it impossible for anyone person to assimilate the totality of human knowledge, it is impossible even to know ones own discipline perfectly thoroughly. Each year the presses of science pro duce a frightening quantity of printed paper. Even in very limited fields, new journals are created every day, devoted to extremely specialized, often very narrowly defined subjects. It is indeed evident that in a field whose scope extends well beyond astronomical or astrophysical research, it is materially impossible to be informed of everything, even with the richest of libraries at hand.

An ideal resource for lecturers, this book provides a comprehensive review of experimental space astronomy. The number of astronomers whose knowledge and interest is concentrated on interpreting observations has grown substantially in the past decades; yet, the number of scientists who are familiar with and capable of dealing with instrumentation has dwindled. All of the authors of this work are leading and experienced experts and practitioners who have designed, built, tested, calibrated, launched and operated advanced observing equipment for space astronomy. This book also contains concise information on the history of the field, supported by appropriate references. Moreover, scientists working in other fields will be able to get a quick overview of the salient issues of observing photons in any one of the various energy, wavelength and frequency ranges accessible in space. This book was written with the intention to make it accessible to advanced undergraduate and graduate students.

We are now living in the multimessenger era in which often weak and elusive astrophysical phenomena need to be studied using different and orthogonal probes and information carriers in order to be fully understood. Different techniques need to be emploted and developped to detect and carefuly characterize electromagnetic waves arising from astrophysical obsjects depending mainly on their energy and other characteristics, such as spectral features and polarization. This book is designed to give advanced undergraduate students a description of the most popular techniques and instrumentation employed in modern astrophysics. Focusing on electromagnetic radiation and its detection spanning from radio- to X-ray wavelengths, it gives a general description of astrophysical observables, such as flux, brightness, throughput, and magnitude. It describes general concepts about geometrical and physical optics at different wavelengths, in an astronomical context, including the concepts of lenses, mirrors, antennas, telescopes, the focal plane, angular resolution, the field of view, and the diffraction limit. The origin of noise and the extraction of a signal from it is also covered, including noise reduction techniques such as filtering, amplification, as well as cryogenic techniques. The theory of signals and the theorems related to digital electronics are also introduced. A set of student laboratory activities is included to illustrate the concepts covered in the book.

Le ciel est, par-dessus le toit, The sky is, up above the roof, Si bleu, si calme! So blue, so calm! Un arbre, par-dessus Je toit, A tree there, up above the roof, Berce sa palme. Waves leaves of palm. La cloche, dans le ciel qu'on voit, A church bell, in the sky I see, Doucement tinte. Softly tolls. Un oiseau, sur l'arbre qu'on voit, A bird, upon the tree I see, Chante sa plainte. Sadly calls. PAUL VERLAINE Like Verlaine, we are in prison. The prison is our Earth, "which is so pretty"; our atmosphere and its clouds, its "marvellous clouds". (You would think that Verlaine, Prevert and Baudelaire had been comparing notes!) The sky is up above the roof ... A tree there, up above the roof ... Stars in the sky, like birds ... their rays, like bells (and here we are with Apollinaire!) What we see opens the way to what we guess at; what we observe Ieads us towards the unobservable. A poem releases images, and the invisible grows big with reality. Astronomcrs are a little like poets (indirectly from the Greek 7tostco, make): they make the universe by interpreting messages, extrapolating spectra, and inventing 'models' of the cosmos or of stars - fictional constructions whose observable part constitutes only a small fraction of the whole, and which only the inductive logic of the theoretician allows us to consider as representing unique physical reality.
