In this unique and fascinating history of science, acclaimed popular science writer William Sheehan - who was awarded a Guggenheim Fellowship for Science Writing - and award-winning geographer John Westfall take us back through the centuries to chronicle the intrepid explorations of scientists and adventurers who studied the transits of Venus in the quest for scientific understanding.

Camille Flammarion (1842-1925) began his career at 16 as a human computer under the great mathematician U. J. J. Le Verrier at the Paris Observatory. He soon tired of the drudgery; he was drawn to more romantic vistas, and at 19 wrote a book on an idea that he was to make his own-the habitability of other worlds. There followed a career as France's greatest popularizer of astronomy, with over 60 titles to his credit. An admirer granted him a chateau at Juvisy-sur-l'Orge, and he set up a first-rate observatory dedicated to the study of the planet Mars. Finally, in 1892, he published his masterpiece, La Planete Mars et ses conditions d'habitabilite, a comprehensive summary of three centuries' worth of literature on Mars, much of it based on his own personal research into rare memoirs and archives. As a history of that era, it has never been surpassed, and remains one of a handful of indispensable books on the red planet. Sir Patrick Moore (1923-2012) needs no introduction; his record of popularizing astronomy in Britain in the 20th century equaled Flammarion's in France in the 19th century. Moore pounded out hundreds of books as well as served as presenter of the BBC's TV program "Sky at Night" program for 55 years (a world record). Though Moore always insisted that the Moon was his chef-d'oeuvre, Mars came a close second, and in 1980 he produced a typescript of Flammarion's classic. Unfortunately, even he found the project too daunting for his publish ers and passed the torch of keeping the project alive to a friend, the amateur astronomer and author William Sheehan, in 1993. Widely regarded as a leading historian of the planet Mars, Sheehan has not only meticulously compared and corrected Moore's manuscript against Flammarion's original so as to produce an authoritative text, he has added an important introduction showing the book's significance in the history of Mars studies. Here results a book that remains an invaluable resource and is also a literary tour-de-force, in which the inimitable style of Flammarion has been rendered in the equally unique style of Moore.

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.

Insect-Plant Interactions is a series devoted to reviews across the breadth of the topic from cellular mechanisms to ecology and evolution. Articles are selected from areas of particular current interest or subjects that would especially benefit from a new review. It is hoped that the interdisciplinary selection in each volume will help readers to enter new fields of insect-plant interactions.

This full-length biography of Edward Emerson Barnard, tells the remarkable tale of endurance and achievement of one of the leading astronomers of the late nineteenth and early twentieth centuries. As a 'man who was never known to sleep', Barnard scoured the heavens endlessly, leaving an astonishing legacy of observations - of planets, satellites, comets, double stars, bright and dark nebulae and globular clusters - that make him one of the greatest observers of all time. This book traces Barnard's life from poverty to international recognition. We are told how he grew up fatherless and in hardship during the American Civil War; that he later acquired a small telescope and discovered so many comets that, despite his lack of formal education, he won a position at the Lick Observatory, California. His success as a professional astronomer then unfolds, and we are told, in particular, how he discovered the fifth satellite of Jupiter and pioneered wide-angle photography of comets and the Milky Way.

Now available in paperback, this beautifully illustrated volume ranges across the entire history of Jupiter studies, from the naked-eye observations of the Babylonians and the Greeks, through the telescopic discoveries of Galileo and T.E.R. Phillips, to the explosion of information received from space probes. It brings our understanding of Jupiter right up to date and includes preliminary findings from the Juno space probe, while also providing valuable practical information for those who wish to make their own observations of the planet. Introducing planetary science in an accessible and engaging way, Jupiter will appeal to those who wish to have a better understanding of this magnificent planet and its unique place in the solar system.

Presented for the first time in popular form is the fascinating true story of the search for the phantom planet Vulcan. As with legends of "the lost continent of Atlantis," scientists and dreamers alike have sought to prove that Vulcan is more than just a myth. Historians of astronomy Richard Baum and William Sheehan have combed the continents, digging through dusty letters and journals, to unravel this mysterious and captivating tale. The planet first assumed a shadowy reality against a backdrop of war and revolution early in the nineteenth century. Le Verrier, the autocratic Director of the Paris Observatory, had unveiled a problem with the motion of the planet Mercury. The indications were of a planet closer to the sun than Mercury. Incredibly, the prediction was immediately fulfilled by an obscure French country doctor using no more than a homemade telescope. The planet, named for the Roman god of fire, was no sooner discovered than it was lost. Still it reappeared often enough to tantalize even skeptics into considering its shadowy existence possible. This fast-paced tale follows the exploits of Le Verrier, and later of his followers, in a pursuit of his unbridled obsessions: to extend the universality of Newton's Laws, to prove Vulcan's existence, and to secure his place in history as one of the greatest astronomers of his time. Stranger than fiction, the story reaches an exciting climax in the final showdown in the unlikeliest of places: America's Wild West. Like gunslingers at high noon, determined astronomers of the opposing camps brave Indians and the elements in their attempt to prove once and for all whether the planet exists. They congregate with some of the most illustrious names of their time for the final test: a grand eclipse of the sun.

Saturn is the showcase of the Solar System. It may not be the largest of the planets, nor the smallest, nor even the only planet with rings. But it is among the most stunningly beautiful objects in the sky, and is always breathtaking when seen in a telescope. This is a beautifully illustrated, authoritative overview of the entire history of humankind's fascination with the ringed planet, from the first low-resolution views of Galileo, Huygens and other early observers with telescopes to the most recent discoveries by the spacecraft Cassini, which studied the planet at close range between 2004 and 2017. The book describes the planet from inside out, details the complicated system of rings and their interaction with Saturn's bevy of satellites, and considers how Saturn formed and the role it played in the early history of the Solar System. Featuring the latest research and a spectacular array of images, it will appeal to the wide audience for astronomy and popular science.

This new and beautifully illustrated account of Venus takes in the most recent research into this mysterious, inhospitable world. Looking at the history of our observations of the planet, from early astronomy to future space missions, it seeks to answer many of the questions that remain unanswered, such as why Venus and Earth, so similar in size and mass, evolved in such different directions, and how Venus acquired its dense carbon-dioxide atmosphere. Above all, it assesses whether life might have escaped from the oven-like temperatures at the surface and evolved to become perpetually airborne - in which case Venus may not be lifeless after all.

The last of the five naked-eye planets discovered in ancient times, Mercury has long been an elusive, enigmatic world. As seen from the Earth, it never emerges far from the Sun, and astronomers in the telescopic era found it challenging to work out such basic data as its rotation period, the inclination of its axis, and whether or not it possessed an atmosphere. In this up-to-date and beautifully illustrated volume, William Sheehan brings our understanding of the planet into clear focus. He deftly traces the history from the earliest observations right up to the most recent explorations using radar and spacecraft. The planet has been surveyed in great detail, revealing vast volcanic plains, water-ice deposits in craters near the poles, and a remarkable core having the highest iron content of any body of the Solar System. A fascinating world in its own right, Mercury also holds important clues for scientists attempting to better understand the origin and evolution of the Earth.

The intriguing narrative of one of astronomy's strangest searches for a planet that never existed.
