Afterglow of Creation: From the Fireball to the Discovery of Cosmic Ripples Marcus Chown
This is the story of the cosmic background radiation - the 'afterglow' of the Big Bang in which the Universe was born - and how it was discovered. Chown brilliantly weaves a tale of the search for the origins of the Universe, beginning in the 1920s and culminating with the flight of the COBE satellite and its crucial discovery.
