Paperback. Condition: New. Print on Demand. This book delves into the observations of the 1874 Venus transit across the sun, an astronomical phenomenon that only occurs twice every century or so. Led by astronomer Simon Newcomb, scientists set up stations across the globe to witness the transit, providing scientists with a unique opportunity to study the details of Venus's atmosphere, its distance from Earth, and its physical properties. The author recounts the challenges faced by the team, including various technical difficulties, bad weather, and changing political circumstances that threatened to disrupt their work. The observations made during the transit provided valuable data for understanding Venus's atmosphere and the physical characteristics of the planet. The insights gained helped form the basis of our current knowledge of Venus and the solar system as a whole. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.

This was probably the best - and certainly the most widly used - heliometer erver made. With it, and in cooperation with a number of northern observatories, he determined the solar parallax by systematic observations of three minor planets, Iris, Victoria, an Shappo. The value he deduced (8.80 arc seconds) was used in the computations of all almanacs until 1968, when it was replaced by 8,794 arc seconds derived by radar echos methods and by observations of Mariner space probes."

Paperback. Condition: New. Print on Demand. This book offers a chance to delve into 14 long-forgotten zones and accompanying star charts observed in the late 1820s and early 1830s, but omitted from the published collection of the KÃ nigsberg Observatory. This trove of astronomical data was pieced together from the original observation sheets of the renowned astronomer Friedrich Wilhelm Bessel and offers insights into his working methods and the development of astronomy in the 19th century. The author has meticulously analyzed the data, identifying errors and biases, and has provided a wealth of information on the observed stars, including many that are not found in other catalogs. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
