Book excerpt: Much of what is known about the universe came from the study of celestial shadows. This book looks in detail at the way eclipses and other celestial shadows have given us amazing insights into the nature of the objects in our solar system and how they are even helping us discover and analyze planets that orbit stars other than our Sun. A variety of eclipses, transits, and occultations of the mooons of Jupiter and Saturn, Pluto and its satellite Charon, asteroids and stars have helped astronomers to work out their dimensions, structures, and shapes - even the existence of atmospheres and structures of exoplanets. Long before Columbus set out to reach the Far East by sailing West, the curved shadow of the Earth on the Moon during a lunar eclipse revealed that we inhabit a round world, a globe. More recently, comparisons of the sunlit and Earthlit parts of the Moon have been used to determine changes in the Earth's brightness as a way of monitoring possible effects in cloud coverage which may be related to global warming. Shadows were used by the Greek mathematician Eratosthenes to work out the first estimate of the circumference of the Earth, by Galileo to measure the heights of the lunar mountains and by eighteenth century astronomers to determine the scale of the Solar System itself. Some of the rarest and most wonderful shadows of all are those cast onto Earth by the lovely "Evening Star" Venus as it goes between the Earth and the Sun. These majestic transits of Venus occur at most two in a century; after the 2012 transit, there is not a chance to observe this phenomenon until 2117, while the more common sweep of a total solar eclipse creates one of the most dramatic and awe-inspiring events of nature. Though it may have once been a source of consternation or dread, solar eclipses now lead thousands of amateur astronomers and "eclipse-chasers" to travel the globe in order to experience the dramatic view under "totality." These phenomena are among the most spectacular available to observers and are given their full due in Westfall and Sheehan's comprehensive study.

Download or read book Advances in Solar Research at Eclipses from Ground and from Space written by Jean-Paul Zahn and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this Advanced Study Institute was to give an account on the most recent results obtained in solar research. Bucharest was chosen to host it, because the capital city of Romania was located right in the middle of the totality path of the last eclipse of the millennium, on 11th August 1999; furthermore the phenomenon was close to reach there its longest duration: 2m 23s. Such a total eclipse is not only a very spectacular event which draws the crowds: to astronomers, solar eclipses still offer the best conditions for observing the lower part of the corona. The Sun plays a crucial role in our very existence. It was responsible for the formation of the Earth, and rendered this planet fit to host living beings, providing the right amount of heat, and this for a long enough span of time. Quite understandably, it has always been a prime target of human curiosity, and more recently one of scientific investigation. During the last century, it was realized that the Sun is a star like billions of others; we learned since that it draws its energy from the nuclear fusion of hydrogen, and we are now able to estimate its age and life expectancy.
Download or read book Advances in Astronomy and Astrophysics written by Zdeněk Kopal and published by Academic Press. This book was released on 2013-10-22 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Astronomy and Astrophysics, Volume 5 is a collection of papers that deals with the Zodiacal light, three dimensional periodic oscillations, the secular variation of mass, and the evolution of binary systems. Some papers discuss the periodicity of the sunspot groups, as well as compact and dispersed cosmic matter. One paper notes that the brightness of the zodiacal light continues to increase right up to the limb of the Sun, where it merges with parts of the solar corona. Another paper discusses analytically and numerically the three families of three-dimensional motions where the members of each family pass very close to one of three equilibrium points. One paper describes the loss of mass in the Sun as being (1) caused by electromagnetic or corpuscular radiation that occurs at a slow rate, or (2) by an explosion of a nova or supernova. One paper examines the periodicity of solar activities, the physical conditions of sunspots, chromospheric flares, prominence, and magnetic fields. The paper notes that different periodicity laws govern the formation frequency and importance of spot groups. The behavior of spot groups also depends on the periodicity process of solar activity. The collection can prove valuable for astro-physicists, astronomers, geochemists, and mathematicians whose works involve cosmology and astronomy.

Available in PDF, EPUB and Kindle. Book excerpt: Eclipses and problems related to them have been, from ancient times, one of the main interests not only of astronomers but indeed of all mankind. The appearance of eclipses, lunar as well as solar, excited the imagination of our ancestors and provoked their curiosity to explain their origin or to use them for the further investigation of celestial bodies. With the present development of astronomy the eclipse problems are not limited to the Sun and the Moon, as in the past, but have been progressively extended to the components of the solar system and to domains of radiations other than optical ones. Our intention is to give an account of all these problems in their theoretical and experimental form with some additions on their historical development. Those of our readers not interested in the historical side may feel at first inclined to ignore this part, but we are sure that eventually they will be sufficiently interested to repair this omission.

Available in PDF, EPUB and Kindle. Book excerpt: In 2017, over 200 million Americans witnessed the spectacular total eclipse of the Sun, and the 2024 eclipse is expected to draw even larger crowds. In anticipation of this upcoming event, this book takes us back in history over 150 years, telling the story of the nation’s first ever eclipse chasers. Our tale follows the chaotic journeys of scientists and amateur astronomers as they trekked across the western United States to view the rare phenomenon of a total solar eclipse. The fascinating story centers on the expeditions of the 1869 total eclipse, which took place during the turbulent age of the chimerical Planet Vulcan and Civil War Reconstruction. The protagonists—a motley crew featuring astronomical giants like Simon Newcomb and pioneering female astronomers like Maria Mitchell—were met with unanticipated dangers, mission-threatening accidents, and eccentric characters only the West could produce. Theirs is a story of astronomical proportions. Along the way, we will make several stops across the booming US railroad network, traveling from viewing sites as familiar as Des Moines, Iowa, to ones as distant and strange as newly acquired Alaska. From equipment failures and botched preparations to quicksand and apocalyptic ‘comets’, welcome to the wild, western world of solar eclipses.
