Selected by 50 notable astronomers from the major sub-fields of the discipline, the articles assembled in this special AAS Centennial collection are accompanied by commentary that provides the scientific-historical context essential to comprehending each article's original impact. Many commentators were contemporaries of the original authors and provide first-person accounts of papers published in the journals—and the earliest reactions they evoked. Arranged in chronological order of publication, these classic papers include works by Subrahmanyan Chandrasekhar, George E. Hale, Fred Hoyle, Edwin Hubble, A.A. Michelson, Henry Norris Russell, Arthur Achuster, Harlow Shapley, and others. Together the articles and commentaries provide a historical window into twentieth-century astronomy and how the results were achieved.
In this collective biography of the more than 1,200 individuals who engaged in astronomical
research, teaching, or practice in the United States between 1859 and 1940, John Lankford
paints a meticulously documented portrait of this community. He tallies the number with and
without doctorates, the number that taught in colleges or universities versus those involved in
industrial or government work, the number of women versus men, and so on. He also
addresses the crucial question of power within the community—what it meant, which
astronomers had it, and what they did with it.
Drawing on more than a decade of archival research, Lankford attends to the numbers in
concise tables and figures, and takes care to focus through biographical sketches on the
human beings his data represent. This dual approach convincingly illustrates how the changing
structure of a scientific community can alter both the career trajectories of its members and the
nature of the scientific research they choose to pursue.

Two hundred years after the first asteroid was discovered, asteroids can no longer be considered mere points of light in the sky. Spacecraft missions, advanced Earth-based observation techniques, and state-of-the-art numerical models are continually revealing the detailed shapes, structures, geological properties, and orbital characteristics of these smaller denizens of our solar system. This volume brings together the latest information obtained by spacecraft combined with astronomical observations and theoretical modeling, to present our best current understanding of asteroids and the clues they reveal for the origin an,d evolution of the solar system.
This collective knowledge, prepared by a team of more than one hundred international authorities on asteroids, includes new insights into asteroid-meteorite connections, possible relationships with comets, and the hazards posed by asteroids colliding with Earth. The book's contents include reports on surveys based on remote observation and summaries of physical properties; results of in situ exploration; studies of dynamical, collisional, cosmochemical, and weathering evolutionary processes; and discussions of asteroid families and the relationships between asteroids and other solar system bodies. Two previous Space Science Series volumes have established standards for research into asteroids. Asteroids III carries that tradition forward in a book that will stand as the definitive source on its subject for the next decade.

Over the past decade, asteroids have come to the forefront of planetary science. Scientists across broad disciplines are increasingly recognizing that understanding asteroids is essential to discerning the basic processes of planetary formation, including how their current distribution bespeaks our solar system’s cataclysmic past. For explorers, the nearest asteroids beckon as the most accessible milestones in interplanetary space, offering spaceflight destinations easier to reach than the lunar surface. For futurists, the prospects of asteroids as commercial resources tantalize as a twenty-first-century gold rush, albeit with far greater challenges than faced by nineteenth-century pioneers. For humanity, it is the realization that asteroids matter. It is not a question of if—but when—the next major impact will occur. While the disaster probabilities are thankfully small, fully cataloging and characterizing the potentially hazardous asteroid population remains unfinished business.
Asteroids IV sets the latest scientific foundation upon which all these topics and more will be built upon for the future. Nearly 150 international authorities through more than 40 chapters convey the definitive state of the field by detailing our current astronomical, compositional, geological, and geophysical knowledge of asteroids, as well as their unique physical processes and interrelationships with comets and meteorites. Most importantly, this volume outlines the outstanding questions that will focus and drive researchers and students of all ages toward new advances in the coming decade and beyond.
Indian scientific achievements in the early twentieth century are well known, with a number of heralded individuals making globally recognized strides in the field of astrophysics. Covering the period from the foundation of the Asiatick Society in 1784 to the establishment of the Indian Association for the Cultivation of Science in 1876, Sen explores the relationship between Indian astronomers and the colonial British. He shows that from the mid-nineteenth century, Indians were not passive receivers of European knowledge, but active participants in modern scientific observational astronomy.
