The invisible universe. Probing the frontiers of astrophysics

As Galileo's discovery of the telescope revolutionized mankind's perception of his visible outermost surroundings, so the past twenty years have irrevocably altered our view of the invisible cosmos. In The Invisible Universe, Eric Chaisson, author of Cosmic Dawn and George Field, former director of the Harvard-Smithsonian Center for Astrophysics, discuss stars and galaxies, and especially the ''hidden matter'' among them - summarizing discoveries made in our Golden Age of astronomy. The book's major emphasis is on the translation of non-visible data into visible pictures, with data-collecting telescopes that transmit information from space to earth via radio. This technology is demonstrated in the book's color photographs, which are computer-enhanced digital images representing a cross-section of the image processing in radio, infared, optical, ultraviolet and x-ray astronomy
