The Astrophysical Journal American Astronomical Society Centennial Issue

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.

"Letters to the Editor" issued as Part 2 and separately paged from v. 148, 1967. Beginning in 2009, the Letters published only online.

A thought provoking study of the powerful impact of images in guiding astronomers' understanding of galaxies through time.

Since the invention of the telescope 400 years ago, astronomers have rapidly discovered countless celestial objects. But how does one make sense of it all? Astronomer and former NASA Chief Historian Steven J. Dick brings order to this menagerie by defining 82 classes of astronomical objects, which he places in a beginner-friendly system known as "Astronomy’s Three Kingdoms.” Rather than concentrating on technicalities, this system focuses on the history of each object, the nature of its discovery, and our current knowledge about it. The ensuing book can therefore be read on at least two levels. On one level, it is an illustrated guide to various types of astronomical wonders. On another level, it is considerably more: the first comprehensive classification system to cover all celestial objects in a consistent manner. Accompanying each spread are spectacular historical and modern images. The result is a pedagogical tour-de-force, whereby readers can easily master astronomy’s three realms of planets, stars, and galaxies.

One of the most attractive features of the young discipline of Space Science is that many of the original pioneers and key players involved are still available to describe their field. Hence, at this point in history we are in a unique position to gain first-hand insight into the field and its development. To this end, The Century of Space Science, a scholarly, authoritative, reference book presents a chapter-by-chapter retrospective of space science as studied in the 20th century. The level is academic and focuses on key discoveries, how these were arrived at, their scientific consequences and how these discoveries advanced the thoughts of the key players involved. With over 90 world-class contributors, such as James Van Allen, Cornelis de Jager, Eugene Parker, Reimar Lüst, and Ernst Stuhlinger, and with a Foreword by Lodewijk Woltjer (past ESO Director General), this book will be immensely useful to readers in the fields of space science, astronomy, and the history of science. Both academic institutions and researchers will find that this major reference work makes an invaluable addition to their collection.

This book shows that astronomical discovery is a complex and ongoing process comprising various stages of research, interpretation and understanding.
