Cosmic Discovery

Martin Harwit's influential book, Cosmic Discovery, is rereleased after more than thirty-five years, with a new preface written by the author. The work chronicles the astronomical discoveries up to the late twentieth century and draws conclusions that major discoveries have often been unexpected, unrelated to prevailing astronomical theories and made by outsiders from other fields. One trend alone seems to prevail: major discoveries follow major technological innovations in observational instruments. The author also examines discovery in terms of its political, financial, and sociological contexts, including the role of industry and the military in enabling new technologies, and methods of funding. The challenges encountered by astronomy in the 1980s are remarkably similar to those astronomers face today. Difficulties persist in controlling recurrent cost overruns on planned missions, and in confronting mounting costs in developing observatories for detecting gravitational waves, high-energy cosmic rays, and particles that might explain dark matter.

• Summarizes the accelerating discovery of cosmic objects and phenomena from antiquity to the late twentieth century
• Addresses fundamental questions astrophysicists were asking in the late 1970s, many of which remain unanswered today
• Promotes the idea that astronomy will need to find new sponsors, sources of funding, and new international partners in order to succeed in the future
