Until Karl Jansky's 1933 discovery of radio noise from the Milky Way, astronomy was limited to observation by visible light. Radio astronomy opened a new window on the Universe, leading to the discovery of quasars, pulsars, the cosmic microwave background, electrical storms on Jupiter, the first extrasolar planets, and many other unexpected and unanticipated phenomena. Theory generally played little or no role – or even pointed in the wrong direction. Some discoveries came as a result of military or industrial activities, some from academic research intended for other purposes, some from simply looking with a new technique. Often it was the right person, in the right place, at the right time, doing the right thing – or sometimes the wrong thing. Star Noise tells the story of these discoveries, the men and women who made them, the circumstances which enabled them, and the surprising ways in which real-life scientific research works.

Describes how radio astronomers made a series of remarkable serendipitous discoveries that changed our understanding of the Universe.

In the shadow of the Cold War, whispers from the cosmos fueled an unlikely alliance between the US and USSR. The search for extraterrestrial intelligence (or SETI) emerged as a foundational field of radio astronomy characterized by an unusual level of international collaboration—but SETI’s use of signals intelligence technology also served military and governmental purposes. In this captivating new history of the collaboration between American and Soviet radio astronomers as they sought to detect evidence of extraterrestrial civilizations, historian Rebecca Charbonneau reveals the triumphs and challenges they faced amidst a hostile political atmosphere. Shedding light on the untold stories from the Soviet side for the first time, she expertly unravels the complex web of military and political interests entangling radio astronomy and the search for alien intelligence, offering a thought-provoking perspective on the evolving relationship between science and power. This is not just a story of radio waves and telescopes; it's a revelation of how scientists on both sides of the Iron Curtain navigated the complexities of the Cold War, blurring the lines between espionage and the quest for cosmic community. Filled with tension, contradiction, and the enduring human desire for connection, this is a history that transcends national boundaries and reaches out to the cosmic unknown, ultimately asking: how can we communicate with extraterrestrials when we struggle to communicate amongst ourselves?

ALMA, the Atacama Large Millimeter/submillimeter Array, situated high in the Chilean desert, is the largest ground-based telescope on Earth. This is an insiders' account of how this complex mega-project came to fruition from authors with intimate knowledge of its past and present. The separate roots of ALMA in the United States, Europe, and Japan are traced to their merger into an international partnership involving more than 20 countries. The book relates the search for a suitable telescope site, challenges encountered in organization, funding, and construction, and lessons learned along the way. It closes with a review of the most significant results from ALMA, now one of the most productive telescopes in the world. Written for a broad spectrum of readers, including astronomers, engineers, project managers, science historians, government officials, and the general public, the eBook edition is available to download as an Open Access publication on Cambridge Core.

This book describes our gradual awareness of a vast, previously concealed Universe. It is a story of expanding horizons and the discovery of invisible worlds. This voyage of discovery is presented within universal themes, such as invisibility, motion, content, form, impermanence, violence and emptiness, beginnings and ends. These are topics that concern us all, helping us take the Universe personally, so each chapter begins with the human aspect of some of these themes. The book is additionally broadened by including the perceptions of artists, poets and writers, as well as with line drawings that forcefully compact a scientific insight.

Ironically, the technology that has made possible so many exciting astronomical discoveries is now jeopardizing the future of observational astronomy. The effects of atmospheric degradation, electromagnetic pollution, and near-Earth space debris are taking their toll. This provocative survey convincingly demonstrates the destructive impact of civilization on current observational astronomy. International astronomers discuss the sources and effects of environmental pollution and degradation and together with specialists from industry, law and elsewhere, they outline possible remedies and the legislation required for successful international regulation of the pollutants. These articles provide essential reference for the professional astronomer, environmentalist, and concerned nonspecialist.

Explains how stars are born, how they evolve and their ultimate fates, for a broad general audience.
