This text presents numerous illustrations of the observed variability of cataclysmic variable stars. It provides a clear explanation and thorough up-to-date overview of this phenomena at a level accessible to the advanced amateur or undergraduate student.

In the tradition of Flatland, and with an infectious enthusiasm, Clifford Pickover tackles the problems inherent in our 3-D brains trying to visualize a 4-D world, muses on the religious implications of the existence of higher-dimensional consciousness, and urges all curious readers to venture into 'the unexplored territory lying beyond the prison of the obvious'.

New Cosmic Horizons tells the extraordinary story of space-based astronomy since the Second World War. Starting with the launch of the V2 rocket in 1946, this book explores the triumphs of space experiments and spacecraft designs and the amazing astronomical results that they have produced. David Leverington examines the fascinating way in which the changing political imperatives of the United States, USSR/Russia and Western Europe have modified their space astronomy programs. He covers all major astronomy missions of the first fifty years of space research: the Soviet Sputnik and American Explorer projects, the subsequent race to the moon, solar and planetary missions, and the wonders of modern astrophysics culminating in the exciting results of the Hubble Space Telescope. Extensively illustrated, New Cosmic Horizons offers amateur and professional astronomers an unusual perspective on the history of astronomy in our time. David Leverington was Design Manager of the GEOS Spacecraft and Meteosat Program Manager for ESA in the 1970s. During his tenure as Engineering Director at British Aerospace in the 1980s, he was responsible for the Giotto spacecraft that intercepted Halley's comet, and the Photon Detector Assembly and solar arrays for the Hubble Space Telescope. He is a Fellow of the Royal Astronomical Society. He lives in Essex, England.

If you have ever watched shooting stars graze the sky or wondered about a particularly bright point of light near the horizon, then this is the book for you. A Skywatcher's Year is the authoritative guide to visible bodies in the night sky throughout the year. Through fifty-two essays, Jeff Kanipe guides you to celestial events and phenomena that occur or are visible with the naked eye and binoculars for each week of the year. He acquaints you not only with up-to-date astronomical information on stars, nebulae, meteors, the Milky Way, and galaxies, but also conveys the beauty and wonder of the night sky. Covering both the Northern Hemisphere and Southern Hemisphere, A Skywatcher's Year helps readers find prominent stars and constellations, bright star clusters, nebulae, and galaxies, and explains how and when to observe prominent annual meteor showers. Kanipe also examines the most frequently-observed celestial body, the Moon, and the intriguing lore surrounding it. A rich and jargon-free look at the sky through the four seasons, this engaging book will give new dimensions to backyard star-gazing.

With this extraordinary handbook, you, too, can frame the stars and have them hanging on your livingroom walls. Astrophotography for the Amateur provides a complete guide to taking pictures of stars, galaxies, the Moon, the Sun, comets, meteors and eclipses, using equipment and materials readily available to the hobbyist. Based on suggestions from readers of the first edition, the new edition has been completely updated and expanded to include new chapters on computer image processing and CCD imaging; expanded advice on choosing cameras and telescopes; completely updated information about films; a much larger bibliography; and hundreds of new photographs (in color and black and white) demonstrating the latest equipment and techniques. Astrophotography for the Amateur has become the standard handbook for all amateur astronomers. This new edition provides an ideal introduction for beginners and a complete handbook for advanced amateurs. It will also appeal to photography enthusiasts who will discover how to take spectacular images with only modest equipment. Michael A. Covington received his Ph.D. at Yale University. He is the author of several books, including Syntactic Theory in the High Middle Ages (Cambridge, 1984). He is a Senior Member of the IEEE and is the Associate Director of the Artificial Intelligence Center at the University of Georgia.

This is the most detailed guide to observing galaxies, clusters and nebulae available in a single volume.

For most objects descriptions are given for a range of telescope apertures; the catalogue contains data not available elsewhere.

CD-ROM and Book. Lost in the glare of Apollo's success, the Gemini program is often forgotten. Without the ten successful manned Gemini missions NASA could not have accomplished Kennedy's seemingly impossible goal of landing a man on the moon in the 1960s. Gemini 6 the fifth manned flight of America's two-man spacecraft. Aboard were Commander Wally Schirra and rookie pilot Tom Stafford. Their original mission flight plan was to attempt the first ever docking and rendezvous in space, an essential step if the pilots flying Apollo would ever be able to meet up in orbit around the moon. The Soviet Union had claimed the first space rendezvous but many felt that unless the pilot was in control and able to manoeuvre around the accompanying vehicle it could not truly be called a rendezvous. On October 25th 1965 the target vehicle, known as Atlas/Agenda failed to make orbit and so the crew of Gemini 6 were suddenly presented with a totally revised and audacious flight plan. The long duration Gemini 7 mission was already scheduled for launch and so the crew of Gemini 6 were told that NASA would attempt a double manned mission and rendezvous.;This was undoubtedly a risky proposition which would stretch the NASA infra-structure to its limits. On December 15th 1965 ace pilot Schirra and rendezvous maestro Stafford closed to within a meter of Gemini 7 and America was one step closer to the moon. Includes: Windows CD-ROM featuring: an exclusive recent interview with Commander Wally Schirra; all of the still photo images taken during the mission; two 28 minutes - 'Gemini Science' and 'Gemini 7 and 6' plus the complete 16 mm film from the mission.

Most scientists now agree that some sixty-five million years ago, an immense comet slammed into the Yucatan, detonating a blast twenty million times more powerful than the largest hydrogen bomb, punching a hole ten miles deep in the earth. Trillions of tons of rock were vaporized and launched into the atmosphere. For a thousand miles in all directions, vegetation burst into flames. There were tremendous blast waves, searing winds, showers of molten matter from the sky, earthquakes, and a terrible darkness that cut out sunlight for a year, enveloping the planet in freezing cold. Thousands of species of plants and animals were obliterated, including the dinosaurs, some of which may have become extinct in a matter of hours. In Impact, Gerrit L. Verschuur offers an eye-opening look at such catastrophic collisions with our planet. Perhaps more important, he paints an unsettling portrait of the possibility of new collisions with earth, exploring potential threats to our planet and describing what scientists are doing right now to prepare for this awful possibility.
Every day something from space hits our planet, Verschuur reveals. In fact, about 10,000 tons of space debris fall to earth every year, mostly in meteoric form. The author recounts spectacular recent sightings, such as over Allende, Mexico, in 1969, when a fireball showered the region with four tons of fragments, and the twenty-six pound meteor that went through the trunk of a red Chevy Malibu in Peekskill, New York, in 1992 (the meteor was subsequently sold for $69,000 and the car itself fetched $10,000). But meteors are not the greatest threat to life on earth, the author points out. The major threats are asteroids and comets. The reader discovers that astronomers have located some 350 NEAs ("Near Earth Asteroids"), objects whose orbits cross the orbit of the earth, the largest of which are 1627 Ivar (6 kilometers wide) and 1580 Betula (8 kilometers). Indeed, we learn that in 1989, a bus-sized asteroid called Asclepius missed our planet by 650,000 kilometers (a mere six hours), and that in 1994 a sixty-foot object passed within 180,000 kilometers, half the distance to the moon. Comets, of course, are even more deadly. Verschuur provides a gripping description of the small comet that exploded in the atmosphere above the Tunguska River valley in Siberia, in 1908, in a blinding flash visible for several thousand miles (every tree within sixty miles of ground zero was flattened). He discusses Comet Swift-Tuttle--"the most dangerous object in the solar system"--a comet far larger than the one that killed off the dinosaurs, due to pass through earth's orbit in the year 2126. And he recounts the collision of Comet Shoemaker-Levy 9 with Jupiter in 1994, as some twenty cometary fragments struck the giant planet over the course of several days, casting titanic plumes out into space (when Fragment G hit, it outshone the planet on the infrared band, and left a dark area at the impact site larger than the Great Red Spot). In addition, the author describes the efforts of Spacewatch and other groups to locate NEAs, and evaluates the idea that comet and asteroid impacts have been an underrated factor in the evolution of life on earth.
Astronomer Herbert Howe observed in 1897: "While there are not definite data to reason from, it is believed that an encounter with the nucleus of one of the largest comets is not to be desired." As Verschuur shows in Impact, we now have substantial data with which to support Howe's tongue-in-cheek remark. Whether discussing monumental tsunamis or the innumerable comets in the Solar System, this book will enthrall anyone curious about outer space, remarkable natural phenomenon, or the future of the planet earth.

Humanity is confronted by and attracted to extremes. Extreme events shape our thinking, feeling, and actions; they echo in our politics, media, literature, and science. We often associate extremes with crises, disasters, and risks to be averted, yet extremes also have the potential to lead us towards new horizons. Featuring essays by leading intellectuals and public figures arising from the 2017 Darwin College Lectures, this volume explores 'extreme' events, from the election of President Trump, the rise of populism, and the Brexit referendum, to the 2008 financial crisis, the Syrian war, and climate change. It also celebrates 'extreme' achievements in the realms of health, exploration, and scientific discovery. A fascinating, engaging, and timely collection of essays by renowned scholars, journalists, and intellectuals, this volume challenges our understanding of what is normal and what is truly extreme, and sheds light on some of the issues facing humanity in the twenty-first century.

Is it possible that extraterrestrial life forms exist within our Galaxy, the Milky Way? This book offers a critical analysis by leading experts in a range of sciences, of the plausibility that other intelligent lifeforms do exist. Exploration of the Solar System, and observations with telescopes that probe deep space, have come up empty handed in searches for evidence of extraterrestrial life. Many experts in the fields of astronomy, biology, chemistry and physics are now arguing that the evidence points to the conclusion that technological civilisations are rare. After ten billion years, and among hundreds of billions of stars, we may well possess the most advanced brains in the Milky Way Galaxy. This second edition contains many new and updated aspects of extraterrestrial research, especially the biological viewpoint of the question.

Constellations are not new to astronomy. Even before the era of printing, patterns of stars have been recognized by humans and their histories have been passed on from generation to generation, culture to culture. This book is the ultimate constellation reference book. Finally, a book exists that brings together a variety of information about constellations, including: the size, visibility, and relative brightness of all eighty-eight constellations; former locations of extinct constellations; the number of visible stars in each constellation; and more. Using tables, this information is presented in the first part of the book so that constellations can be readily compared and a general view of them developed. In the second part of the book, each constellation is taken in turn, with a star chart and map illustrating the associated celestial figure, supported by a comprehensive list of essential properties. This highly illustrated volume provides the most complete reference to date covering all aspects of the constellations and will be helpful for astronomers, both amateur and professional, educators and science writers.

Excellence in observation is crucial to astronomy. Optical designers, engineers and astronomers have tried all kinds of novel ways to improve telescope design, in the quest for better and more accurate telescopes. In this book, Peter L. Manly surveys more than 150 unusual telescope designs. They are all built by amateur and professional astronomers to suit some special need. This survey includes an inflatable telescope, and one with a liquid mirror. Every so often, a neglected design comes back into fashion: the largest telescopes now under construction use the alt-azimuth design that was ignored for over a century, and liquid mirror telescopes can be used for zenithal astronomy. The author shows why a particular engineering approach makes each telescope unique, and explains the rationale behind the design. The effects on telescope performance are also discussed where possible. This is not just a collection of weird and wonderful devices that proved to be false starts: the author includes the first instrument to measure star diameters, and the first useful radio telescope. This book is a resource and stimulus for anyone who likes to build astronomical telescopes.

How can you find new minor planets, comets and novae? How can you use photoelectric detectors to derive the temperatures of stars?

It also explains how to record and catalog observations using recognized professional terminology and classification schemes. The volume's emphasis throughout is on giving amateur astronomers sound information to use at the telescope. The most effective and efficient techniques are presented so that observers can apply those that are most suitable to their own equipment and degree of experience. This comprehensive survey of practical methods of observation will develop the observational skills of the avid novice and will also satisfy the more demanding needs of the experienced amateur astronomer.

For the first time the inside story of Russia's marketing of their space program to the West is chronicled by one who was there. The colourful tales are told, warts and all. How the door to Russia's long hidden space pro-gram was opened during the era of Soviet perestroika, the political struggle on the signing of the first contract between the Russians and NASA, the push to change space station Freedom into a co-operative venture, the willingness of the Russians to use free markets against the wishes of NASA and how the Russian space station Mir became a commercial platform, are all told in a relaxed and engaging style by the author, who is the only American ever to work within the Russian space program. The book chronicles the author's 14 year journey to use Russian assets to strengthen the American space program. Included is the behind-the-scenes of signing Dennis Tito, working with entertainment icons like James Cameron and Mark Burnett and the electrifying ride that was MirCorp. The book discusses the boycott organised by NASA to prevent MirCorp's success and the drama behind the world's only commercial manned expedition that sent two men to the Mirspace station for over two months, with no government funding. It is a tale of strong characters. Readers are given a front-row seat on the decade-long clash between the Russian chief Yuri Semenov and NASA's Dan Goldin, a paradoxical battle that saw the Russians embracing American open markets and NASA clinging to the Cold War model for space exploration.

"Have you ever seen a total solar eclipse?" If the question caused you to search your memory, the correct answer would have been "no." A common response is: "Yes-I saw one, it was about 90% partial eclipse where I lived." A 90% partial eclipse is indeed a remarkable phenomenon, but true totality leaves all else in the shade, in all senses of the phrase. Ask the question of anyone who has experienced the full sensation of being obliterated by the moon's shadow, and they will reply "yes"-without hesitation-and continue with a monologue describing the overwhelming experiences and unique phenomena that ensued. On 21 August 2017 millions of people across the United States witnessed "The Great American Eclipse" of the Sun. The moment it was over, people around the world were asking questions: what caused the weird shadows and colors in the build up to totality? Were those ephemeral bands of shadows gliding across the ground in the seconds before totality real or an optical illusion? Why this, what that, but above all: where and when can I see a total solar eclipse again? Eclipses: What Everyone Needs to Know helps explain the profound differences between a 99.99% partial eclipse and true totality, and inform readers how to experience this most beautiful natural phenomenon successfully. It covers eclipses of sun, moon, and other astronomical objects, and their applications in science, as well as their role in history, literature, and myth. It describes the phenomena to expect at a solar eclipse and the best ways to record them-by camera, video, or by simple handmade experiments. The book covers the timetable of upcoming eclipses, where the best locations will be to see them, and the opportunities for using them as vehicles for inspiration and education. As a veteran of seven total solar eclipses, physicist Frank Close is an expert both on the theory and practice of eclipses. Eclipses: What Everyone Needs to Know is a popular source of information on the physics of eclipses.
