In this book Dr. Maccone explains how the Sun can serve as an enormous gravitational lens for amplifying signals emitted by distant stars, planets, and civilizations. He proposes various space missions over the next several decades for utilizing the phenomenon. The book provides semitechnical details adequate for scientists and engineers to evaluate, plan, and begin the technical design for such space missions.
"Scientists and engineers of the world have the moral duty, and must face the challenge to use the most gigantic magnifying lens of their solar system: the one which Einstein predicted to be produced by the Sun's bending of space. Claudio Maccone, with his profound scientific and technical knowledge, his active drive in organizing international meetings dedicated to this fascinating and farsighted enterprise, is the best and most internationally recognized creative specialist whom we thank for giving us such an illuminating book on opening our astronomically-sized eye on our cosmos. We are not bound to stay bound!"

"In this remarkably interesting and informative book an internationally acknowledged expert gives a comprehensive account of our present knowledge of the Sun as a gravitational lens and of its possible application as a giant telescope. This detailed and up-to-date analysis - which is partly based on the author's experience as organizer of a series of scientific topical conferences since 1992 in Turin, Italy - is a major contribution to a topic important for the future of space exploration and also exceptionally interesting. The book thoroughly deserves to be great success."
