This beautifully structured book presents the essentials of William and Caroline Herschel's pioneering achievements in late 18th-century astronomy. Michael Hoskin shows that William Herschel was the first observational cosmologist and one of the first observers to attack the sidereal universe beyond the solar system: Herschel built instruments far better than any being used at the royal observatory. Aided by his sister Caroline, he commenced a great systematic survey that led to his discovery of Uranus in 1781. Unlike observers before him, whose telescopes did not reveal them as astronomical objects, Herschel did not ignore misty patches of light. Hoskins points out Herschel's achievement in surveying, cataloguing, and describing them as "nebulae" and even coming to the correct conclusion that their structure evolved over time, with Newton's gravity being the agent of change. Herschel's surveys established a new astronomy - looking at the universe rather than the planets! Michael Hoskin's account includes sketches and diagrams from Herschel's manuscripts in the Royal Astronomical Society Archives in which he attempts to delineate the structure of the Milky Way galaxy. While it is well-known that Herschel was a revolutionary in telescope design who constructed the world's largest telescopes, Hoskin also gives the full picture of the man as an entrepreneur who built and traded some 400 telescopes. Hoskin also pays close attention to the role of William's sister Caroline Herschel, who is usually portrayed as a "helpmate" to her brother. But in fact she became a significant astronomer in her own right. This book also offers a wealth of information of the wider Herschel family. It is enriched by a complete set of portraits of William and Caroline Herschel with an extensive set of images of their residences and closes with a charming appendix on how visitors to the Herschels recorded their encounters. William and Caroline Herschel - Pioneers in Late 18th-Century Astronomy will appeal to amateur astronomers and all those interested in popular astronomy. This book will rapidly establish itself as the primary introductory work for students, astronomers, and scholars working on the history of natural science in the late 18th century.

Part B of Planetary Astronomy from the Renaissance to the Rise of Astrophysics continues the history of celestial mechanics and observational discovery through the eighteenth and nineteenth centuries. It provides a synoptic view of the main developments and furnishes details about the lives, ideas, and interactions of the various astronomers involved. Twelve different authors have contributed their expertise to this book that begins with the reception of Newton's inverse-square law. In the remainder, a large place is given to the development of the mathematical theory of celestial mechanics from Clairaut and Euler to LeVerrier, Newcomb, Hill, and Poincare. This emphasis is balanced by other chapters on observational discoveries and the rapprochement of observation and theory (for instance, the discovery of Uranus and the asteroids, use of Venus transits to refine solar parallax, introduction of the method of least squares, and the development of planetary and satellite ephemerides). Lists of "Further Reading" provide entree to the literature of the several topics. This book will be of great interest to historians of science and astronomers.

Astronomy is one of the oldest sciences, and one which has repeatedly led to fundamental changes in our view of the world. This book covers the history of our study of the cosmos from prehistory to a survey of modern astronomy and astrophysics. It does not attempt to cover everything, but deliberately concentrates on the important themes and topics, including stellar astronomy in the seventeenth and eighteenth centuries--the source of many important concepts in modern astronomy--and the Copernican revolution, which led to the challenge of ancient authorities in many areas other than astronomy. This is an essential text for students of the history of science and for students of astronomy who require a historical background to their studies.

"Discoverers of the Universe" tells the gripping story of William Herschel, the brilliant, fiercely ambitious, emotionally complex musician and composer who became court astronomer to Britain's King George III, and of William's sister, Caroline, who assisted him in his observations of the night sky and became an accomplished astronomer in her own right. Together, they transformed our view of the universe from the unchanging, mechanical creation of Newton's clockmaker god to the ever-evolving, incredibly dynamic cosmos that it truly is.

William was in his forties when his amateur observations using a homemade telescope led to his discovery of Uranus, and an invitation to King George's court. He coined the term "asteroid," discovered infrared radiation, was the first to realize that our solar system is moving through space, discovered 2,500 nebulae that form the basis of the catalog astronomers use today, and was unrivalled as a telescope builder. Caroline shared William's passion for astronomy, recording his observations during night watches and organizing his papers for publication. She was the first salaried woman astronomer in history, a pioneer who herself discovered nine comets and became a role model for women in the sciences.

Written by the world's premier expert on the Herschels, "Discoverers of the Universe" traces William and Caroline's many extraordinary contributions to astronomy, shedding new light on their productive but complicated relationship, and setting their scientific achievements in the context of their personal struggles, larger-than-life ambitions, bitter disappointments, and astonishing triumphs.

An introduction to the history of Western astronomy from prehistoric times to the origins of astrophysics in the mid nineteenth century. Emphasis is given to such topics as the merging of Babylonian and Greek astronomy in later Antiquity, Kepler's conversion of astronomy into a branch of dynamics, and the first explorations of the universe of stars.

The Far Traveler's Saga is a collection of three books of poetry which were written to record and share the experiences of a Seeker. The poems are presented here so that any who might benefit from the words on a mental, emotional, or spiritual level might have words of wisdom, warning, and invitation from one who has pressed forth into the unknown. Glory to you, Far Traveler and Life everlasting

The astronomical observations of William Herschel (1738-1822) made him question the accepted model of the clockwork universe. This volume explains the development of Herschel's thoughts on what he called 'the construction of the heavens' and reprints his principal papers on this subject. The preliminary chapters provide an introduction to Herschel, including his unusual path to astronomy, the discovery of Uranus and his work on the evolution of stellar clusters, which eventually led him to challenge the unchanging Newtonian universe. The second half of the text comprises eight of Herschel's key papers on what we today would call cosmology, representing his progress between 1783 and 1814, fully annotated with historical notes and modern astrophysical explanations. Ideal for undergraduate and postgraduate students in the history of science and in astronomy, this volume explains Herschel's pivotal role in the transformation from the clockwork universe to the 'biological' universe of modern astronomy.
