Book excerpt: Excerpt from The Apparent Projection of Stars Upon the Bright Limb of the Moon at Occultation, and Similar Phenomena at Total Solar Eclipses, Transits of Venus and Mercury, Etc;, Etc This paper is prompted mainly by the many references made by astronomers and astronomical publications to Baily's Beads in cases of total solar eclipses; to the black drop and ligament in transits of Mercury and Venus over the Sun's disc; to the projection of a star upon the bright body of the Moon at immersion or emersion of occultation; to stars and the satellites of Jupiter seen through the limb or body of that planet at occultation; to planets surrounded by an atmosphere of great depth; and to empirical corrections to the semidiameters of the Sun and Moon at meridian transits. We have lately examined the reports of the observers of the transits of Venus in I874 and 1882; of the transits of Mercury since 1878, and the reports of the total solar eclipses since' 1860; and we are amazed at the crude and apparently indigested explanations given for certain appear auces attending the phenomena. There would seem to have been a desire to seek explanations in some obscure cause or causes - such as the poor character of the objective used, the lack of sharpness in the limbs of the planets (owing to their possessing an atmosphere), diffraction, telescopic and occular irradiation, astigmatism, sympathetic attraction, etc. These explanations are very unsatisfactory, and the experienced Observer, who has observed occultations of stars by the Moon or by Jupiter, meridian transits of the Moon, transits of Mercury and Venus across the Sun's disc, and total solar eclipses in a serene atmosphere, knows that the outlines of the planets, the Moon, and the Sun are remarkably sharp and steady, even under high magnifying power; that the Observations made under such conditions are satisfactory; and that there are no extraordinary phe nomena present.

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 David Levy s Guide to Eclipses Transits and Occultations written by David H. Levy and published by Cambridge University Press. This book was released on 2010-08-19 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this simple guide, David Levy inspires readers to experience the wonder of eclipses and other transient astronomical events for themselves. Covering both solar and lunar eclipses, he gives step-by-step instructions on how to observe and photograph eclipses. As well as explaining the science behind eclipses, the book also gives their historical background, discussing how they were observed in the past and what we have learned from them. This personal account contains examples from the 77 eclipses the author has witnessed himself. The guide also includes chapters on occultations of stars and planets by the Moon and of asteroids by stars, and the transits of Mercury and Venus. Tables of future eclipses make this invaluable for anyone, from beginners to practised observers, wanting to learn more about these fascinating events.

Download or read book Eclipse Phenomena in Astronomy written by F. Link and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 281 pages. 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.
