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.

The hum of the starship's engines echoed through the vastness of space as Captain Elysia Nova stood on the observation deck, her eyes fixed on the kaleidoscope of distant galaxies. Beyond the transparent alloy windows, a tapestry of twinkling lights unfolded, painting the cosmic canvas with luminescent hues. This was the Ozymandias, the pinnacle of human engineering, navigating the cosmic ocean.

Two questions guide this seven-year project: First, how can we approach the phenomenon, representation, and interpretation of total solar eclipses? Second, how can we heal the historical divide separating the natural sciences from the humanities, arts, history, and theology? The result of this interdisciplinary investigation into eclipses is an exciting look behind the scenes - into labs, archives, and museums, as well as around fieldwork in astronomy, meteorology, animal behaviour, and ecophysiology. Carefully prepared for readers from all backgrounds, these voices invite us to imagine a liberated mode of discovery, perception, creativity, and knowledge-production across the traditional academic divisions. A uniquely prismatic representation of total solar eclipses emerges, itself rising to a model of communal thinking, together, across disciplinary borders. This book is Tom McLeish's final project and scholarly testament. Dedicated to him and to astrophysicist Jay M. Pasachoff (contributing author of a chapter about the solar corona, also Pasachoff's final piece of writing), the volume is a friendly companion to the chase of knowledge, encouraging its readers to embark upon their own interdisciplinary journey of discovery.

Lunar and solar eclipses have always fascinated human beings. Digging deep into history, Clemency Montelle examines the ways in which theoretical understanding of eclipses originated and how ancient and medieval cultures shared, developed, and preserved their knowledge of these awe-inspiring events. Eclipses were the celestial phenomena most challenging to understand in the ancient world. Montelle draws on original research—much of it derived from reading primary source material written in Akkadian and Sanskrit, as well as ancient Greek, Latin, and Arabic—to explore how observers in Babylon, the Islamic Near East, Greece, and India developed new astronomical and mathematical techniques to predict and describe the features of eclipses. She identifies the profound scientific discoveries of these four cultures and discusses how the societies exchanged information about eclipses. In constructing this history, Montelle establishes a clear pattern of the transmission of scientific ideas from one culture to another in the ancient and medieval world. Chasing Shadows is an invitingly written and highly informative exploration of the early history of astronomy.

From an award-winning author, astronomer, and anthropologist, an exploration of the scientific and cultural significance of the mesmerizing cosmic display. Since the first humans looked up and saw the sun swallowed by darkness, our species has been captivated by solar eclipses. Astronomer and anthropologist Anthony Aveni explains the history and culture surrounding solar eclipses, from prehistoric Stonehenge to Babylonian creation myths, to a confirmation of Einstein’s theory of general relativity, to a spectacle that left New York City in the moon’s shadow, to future eclipses that will capture human imaginations. In one accessible and engaging read, Aveni explains the science behind the phenomenon, tracks eclipses across the ancient world, and examines the roles of solar eclipses in modern times to reveal the profound effects these cosmic events have had on human history. Colored by his own experiences—Aveni has witnessed eight total solar eclipses in his lifetime—his account of astronomy’s most storied phenomenon will enthrall anyone who has looked up at the sky with wonder. “Aveni’s authoritative but accessible text is the clearest statement of the way our perception of eclipses has changed over the centuries.” —Stuart Clark, New Scientist “Authoritative and engaging.” —Marcelo Gleiser, NPR’s 13.7 “A recommended way to share the spirit of the occasion.” —Laurence A. Marschall, Natural History magazine “Everything you need to enjoy a solar eclipse—and even predict one, just like the Babylonians did! Aveni’s entertaining explorations show the very different impacts eclipses have had on past and present cultures.” —David DeVorkin, National Air and Space Museum, Smithsonian Institution
