Bode S Law And The Discovery Of Juno

Johann Bode developed a so-called law of planetary distances best known as Bode’s Law. The story of the discovery of Juno in 1804 by Karl Harding tells how Juno fit into that scheme and is examined as it relates to the philosopher Georg Hegel’s 1801 thesis that there could be no planets between Mars and Jupiter. By 1804 that gap was not only filled but had three residents: Ceres, Pallas and Juno! When Juno was discovered no one could have imagined its study would call into question Newton’s law of gravity, or be the impetus for developing the mathematics of the fast Fourier transform by Carl Gauss. Clifford Cunningham, a dedicated scholar, opens to scrutiny this critical moment of astronomical discovery, continuing the story of asteroid begun in earlier volumes of this series. The fascinating issues raised by the discovery of Juno take us on an extraordinary journey. The revelation of the existence of this new class of celestial bodies transformed our understanding of the Solar System, the implications of which are thoroughly discussed in terms of Romantic Era science, philosophy, poetry, mathematics and astronomy. The account given here is based on both English and foreign correspondence and scientific papers, most of which are translated for the first time.

The 1846 discovery of Neptune is one of the most remarkable stories in the history of science and astronomy. John Couch Adams and U.J. Le Verrier both investigated anomalies in the motion of Uranus and independently predicted the existence and location of this new planet. However, interpretations of the events surrounding this discovery have long been mired in controversy. Who first predicted the new planet? Was the discovery just a lucky fluke? The ensuing storm engaged astronomers across Europe and the United States. Written by an international group of authors, this pathbreaking volume explores in unprecedented depth the contentious history of Neptune’s discovery, drawing on newly discovered documents and re-examining the historical record. In so doing, we gain new understanding of the actions of key individuals and sharper insights into the pressures acting on them. The discovery of Neptune was a captivating mathematical moment and was widely regarded at the time as the greatest triumph of Newton’s theory of universal gravitation. The book therefore begins with Newton’s development of his ideas of gravity. It examines too the mathematical calculations related to the discovery of Neptune, using new theories and tools provided by advances in celestial mechanics over the past twenty years. Through this process, the book analyzes why the mathematical approach that proved so potent in the discovery of Neptune, grand as it was, could not help produce similar discoveries despite several valiant attempts. In the final chapters, we see how the discovery of Neptune marked the end of one quest—to explain the wayward motions of Uranus—and the beginning of another quest to fill in the map and understand the nature of the outer Solar System, whose icy precincts Neptune, as the outermost of the giant planets, bounds.

Grounded in historical studies of asteroids from the nineteenth century, Asteroids is a fully up-to-date view of these remarkable objects. Without resorting to any technical diagrams or mathematics, Clifford J. Cunningham shows that asteroids are not just rocks in space, but key to understanding the life and death on Earth of both animals and humans. From space missions to the asteroids’ starring role in literature and film, Cunningham precisely and entertainingly looks at the place asteroids have in our solar system and how they affect our daily lives.

Astronomy in Depth fills the need for a textbook that covers pre-university level Astronomy courses (in the UK, the GCSE syllabuses) and provides numerical examples to help students. It is also written as a serious foundation in Astronomy for amateurs who want to take a more detailed approach than can be found in the bulk of introductory astronomy books. Almost every aspect of astronomy is considered, from Earth and its place in the solar system, through instrumentation, the planets, stars, and galaxies, to black holes and the beginnings of cosmology. This book is perfect for anyone who wants to get to know astronomy in detail, as quickly as possible.

Bennu, named for the ancient Egyptian phoenix, was the chosen destination of OSIRIS-REx, NASA’s premier mission of asteroid exploration, launched in 2016. Study of the asteroid is important in safeguarding the future of planet Earth, but Bennu is also a time capsule from the dawn of our Solar System, holding secrets over four-and-a-half billion years old about the origin of life and Earth as a habitable planet. In 2020 the OSIRIS-REx spacecraft successfully landed on the surface of Bennu and collected pristine asteroid material for delivery to Earth in September 2023. Scientific studies of the samples, along with data collected during the rendezvous, promise to help find answers to some of humanity’s deepest questions: Where did we come from? What is our destiny in space? This book, the world’s first complete (and stereoscopic) atlas of an asteroid, is the result of a unique collaboration between OSIRIS-REx mission leader Dante Lauretta and Brian May’s London Stereoscopic Company. Lauretta’s colleagues include Carina Bennett, Kenneth Coles, and Cat Wolner, as well as Brian May and Claudia Manzoni, who became part of the ultimately successful effort to find a safe landing site for sampling. The text details the data collected by the mission so far, and the stereo images have been meticulously created by Manzoni and May from original images collected by the OSIRIS-REx cameras.
