With its clear skies and low humidity, the southwestern United States is an astronomer’s paradise where observatories like Kitt Peak have redefined the art of skywatching. The region is unique in its loose federation of like-minded research outposts and in the quantity and diversity of its observatories—places captured in this unique guidebook. Douglas Isbell and Stephen Strom, both intimately involved in southwestern astronomy, have written a practical guide to the major observatories of the region for those eager to learn what modern telescopes are doing, to understand the role each of these often quirky places has played in advancing our understanding of the cosmos, and hopefully to visit and see the tools of the astronomer up close. For each observatory, the authors describe its history, highlights of its contributions to astronomy—with an emphasis on recent results—and information for visitors. Also included are wide-ranging interviews with astronomers closely associated with each site. Observatories covered range from McDonald in Texas to Palomar in California, with significant outposts in between: Arizona’s Kitt Peak National Observatory southwest of Tucson, the Lowell Observatory in Flagstaff, and the Whipple Observatory outside Amado; and New Mexico’s Very Large Array near Socorro and Sacramento Peak close to Sunspot. In addition to describing these established institutions, they also take a look ahead to the most powerful ground-based telescope in the world just beginning to operate at full power on Mount Graham in Safford, Arizona. With more than three dozen illustrations, Observatories of the Southwest is accessible to amateur astronomers, tourists, students, and teachers—anyone fascinated with the contributions that astronomy has made to deepening our understanding of humanity’s place in the universe, whether exploring the solar system from Lowell Observatory or studying the birth of stars using the army of giant radio telescopes at the Very Large Array. This book aims to inspire visits to these sites by illuminating the major scientific questions being pursued every clear night beneath the dark skies of the Southwest and the amazing machinery that makes these pursuits possible.

A guide to the Kitt Peak telescopes.

As a site of scientific activity, the Southwest may be best known for atomic research at Los Alamos and astronomical observations at Kitt Peak. But as George Webb shows, these twentieth-century endeavors follow a complex history of discovery that dates back to Spanish colonial times, and they point toward an exciting future. Ranging broadly over the natural and human sciences, Webb shows that the Southwest—specifically Arizona, New Mexico, and west Texas—began as a natural laboratory that attracted explorers interested in its flora, fauna, and mineral wealth. Benjamin Silliman's mining research in the nineteenth century, for example, marked the development of the region as a colonial outpost of American commerce, and A. E. Douglass's studies of climatic cycles through tree rings attest to the rise of institutional research. World War II and the years that followed brought more scientists to the region, seeking secluded outposts for atomic research and clear skies for astronomical observations. What began as a colony of the eastern scientific establishment soon became a self-sustaining scientific community. Webb shows that the rise of major institutions—state universities, observatories, government labs—proved essential to the growth of Southwest science, and that government support was an important factor not only in promoting scientific research at Los Alamos but also in establishing agricultural and forestry experiment stations. And in what had always been a land of opportunity, women scientists found they had greater opportunity in the Southwest than they would have had back east. All of these factors converged at the end of the last century, with the Southwest playing a major role in NASA's interplanetary probes. While regionalism is most often used in studying culture, Webb shows it to be equally applicable to understanding the development of science. The individuals and institutions that he discusses show how science was established and grew in the region and reflect the wide variety of research conducted. By joining Southwest history with the history of science in ways that illumine both fields, Webb shows that the understanding of regional science is essential to a complete understanding of the Southwest.

Steve Mulligan has applied his large-format camera skills to his most recent fifteen-year-long project in locating and photographing these prehistoric observatories in the American Southwest.

The Heavens on Earth explores the place of the observatory in nineteenth-century science and culture. Astronomy was a core pursuit for observatories, but usually not the only one. It belonged to a larger group of “observatory sciences” that also included geodesy, meteorology, geomagnetism, and even parts of physics and statistics. These pursuits coexisted in the nineteenth-century observatory; this collection surveys them as a coherent whole. Broadening the focus beyond the solitary astronomer at his telescope, it illuminates the observatory’s importance to technological, military, political, and colonial undertakings, as well as in advancing and popularizing the mathematical, physical, and cosmological sciences. The contributors examine “observatory techniques” developed and used not only in connection with observatories but also by instrument makers in their workshops, navy officers on ships, civil engineers in the field, and many others. These techniques included the calibration and coordination of precision instruments for making observations and taking measurements; methods of data acquisition and tabulation; and the production of maps, drawings, and photographs, as well as numerical, textual, and visual representations of the heavens and the earth. They also encompassed the social management of personnel within observatories, the coordination of international scientific collaborations, and interactions with dignitaries and the public. The state observatory occupied a particularly privileged place in the life of the city. With their imposing architecture and ancient traditions, state observatories served representative purposes for their patrons, whether as symbols of a monarch’s enlightened power, a nation’s industrial and scientific excellence, or republican progressive values. Focusing on observatory techniques in settings from Berlin, London, Paris, and Rome to Australia, Russia, Thailand, and the United States, The Heavens on Earth is a major contribution to the history of science.
