By James Lattis & Kelly Tyrrell

A richly illustrated history of Wisconsin’s astronomical innovations.

Explore the remarkable story of Wisconsin astronomers whose curiosity, persistence, and innovation helped us better understand our universe. Chasing the Stars traces the history of the University of Wisconsin’s Washburn Observatory, where some of the world’s most cutting-edge astronomical inventions were born. Learn about the earliest Indigenous stargazers, the women who worked as the first human computers, the astronomers who sold time by the stars, the scientists who shrank the Milky Way, and the crucial role Wisconsin astronomers played in the development of modern astrophysics and space astronomy. This extraordinary book features more than 100 modern and historic photographs that illustrate the people and science behind Wisconsin’s astronomical innovations. Designed for lay readers and astronomers alike, Chasing the Stars inspires all of us to look up at the sky in wonder.

Attend the book launch virtually or in person on May 7, 2024 in Madison, WI.

“Filled with fascinating astronomy-related facts…. Chasing the Stars [is] a thorough, enlightening history of an important scientific site and the personalities who brought it to life.” —Foreword Reviews

“Lattis and Tyrrell give us a masterful tour of Washburn Observatory, its legacy of astronomical discovery, and the key figures who forever changed our understanding of the cosmos. Readers will find delightful insights on these pages that bring this rich history to life and instill a desire to gaze at the stars.”

—Kenneth Sembach, former director of the Space Telescope Science Institute

“Through enchanting photos and compelling tales of astronomers, Lattis and Tyrrell shed light on the impressive innovations Wisconsin has contributed to the field of astrophysics. From the novel ways of collecting light from space to the new technologies sent to space on early satellites, readers will be fascinated to learn how Wisconsin astronomers have influenced our understanding of the universe.”

—Dr. Amanda Bauer, deputy director and head of science and education, Yerkes Observatory 

“This fascinating and detailed account of the history of astronomy in Wisconsin highlights a diverse set of connections, from the construction of the University of Wisconsin’s first observatory in the late 1880s, to General Mills, Oscar Meyer, railroads, and the creation of the American Astronomical Society. Chasing the Stars recounts for us how Wisconsin’s astronomers came to be leaders in this field for more than a century and reminds us of why astronomy is a deeply human endeavor that appeals to professionals and nonprofessionals alike.”

—Dr. Andrea Ghez, UCLA astrophysicist and Nobel laureate
