In 2004, Venus crossed the sun's face for the first time since 1882. Some did not bother to step outside. Others planned for years, reserving tickets to see the transit in its entirety. But even this group of astronomers and experience seekers were attracted not by scientific purpose but by the event's beauty, rarity, and perhaps--after this book--history. For previous sky-watchers, though, transits afforded the only chance to determine the all-important astronomical unit: the mean distance between earth and sun.

Eli Maor tells the intriguing tale of the five Venus transits previously observed and the fantastic efforts made to record them. This is a story of heroes and cowards, of reputations earned and squandered, all told against a backdrop of phenomenal geopolitical and scientific change.

With a novelist's talent for the details that keep readers reading late, Maor tells the stories of how Kepler's misguided theology led him to the laws of planetary motion; of obscure Jeremiah Horrocks, who predicted the 1639 transit only to die, at age 22, a day before he was to discuss the event with the only other human known to have seen it; of the unfortunate Le Gentil, whose decade of labor was rewarded with obscuring clouds, shipwreck, and the plundering of his estate by relatives who prematurely declared him dead; of David Rittenhouse, Father of American Astronomy, who was overcome by the 1769 transit's onset and failed to record its beginning; and of Maximilian Hell, whose good name long suffered from the perusal of his transit notes by a color-blind critic.

Moving beyond individual fates, Maor chronicles how governments' participation in the first international scientific effort--the observation of the 1761 transit from seventy stations, yielding a surprisingly accurate calculation of the astronomical unit using Edmund Halley's posthumous directions--intersected with the Seven Years' War, British South Seas expansion, and growing American scientific prominence. Throughout, Maor guides readers to the upcoming Venus transits in 2004 and 2012, opportunities to witness a phenomenon seen by no living person and not to be repeated until 2117

Seit den alten Hochkulturen vor etwa 4000 Jahren haben die Sterne die Menschen fasziniert und diese sich bemuht, durch den Bau von Sternwarten mehr uber den Sternhimmel herauszufinden. In diesem Buch werden erstmals die 82 wichtigsten Sternwarten von Stonehenge bis in unsere Zeit vorgestellt. Einem kurzen Begleittext zu jeder Sternwarte sind jeweils farbige Fotographien sowie - vor allem bei den alteren Observatorien - Grundrisszeichnungen an die Seite gestellt. Somit ist dieser Bildband nicht nur eine Fundgrube fur den Berufs- und Hobbyastronomen, sondern auch eine baugeschichtlich und kulturhistorisch hoechst interessante Bilddokumentation des mit einem wissenschaftlichen Zweck unmittelbar verbundenen "Gebaudetypus Sternwarte".

The universe contains many unusual sights and sounds, most of which are either very difficult to witness or simply go unnoticed. With the right tools, time, and location, some of the often talked about but seldom seen and heard gems in our skies can finally be observed. This book introduces readers to the rare and ephemeral happenings above our heads. It offers a crash course in astronomical history, detailing the observations, assumptions, and inventions of different cultures over time as they turned their studies to the stars. Using this as a baseline to redefine truly "rare" occurrences, Jonathan Powell then provides modern-day astronomers at all levels with pointers for what they can witness and when. From phenomena as old and far-off as a supernova witnessed a thousand years ago, and as recent and nearby as Sputnik's famous beeping, this book covers everything that one must know to see, hear, and appreciate the astronomical events happening around us.

Enrich your next sea vacation with this fun how-to guide to observing and doing astrophotography on water. Collecting together the author's five decades of astrophotography and teaching experience, this book shares all the practical information you will need to start on your own astronomy adventure. Part I is full of practical advice on what to pack, the best ways to enjoy the night sky from your cruise ship observatory, specific astronomical objects and events to look out for, and myriad other useful tips. Part II gives you a crash course on astrophotography at sea, teaching you the nitty-gritty details of taking pictures of the night sky. Proof that it can be done is provided by the many amazing color astrophotographs taken by the author while following the steps laid out in this book.

There are currently thousands of amateur astronomers around the world engaged in astrophotography at a sophisticated level. Their ranks far outnumber professional astronomers doing the same and their contributions both technically and artistically are the dominant drivers of progress in the field today. This book is a unique collaboration of individuals world-renowned in their particular area and covers in detail each of the major sub-disciplines of astrophotography. This approach offers the reader the greatest opportunity to learn the most current information and the latest techniques directly from the foremost innovators in the field today. "Lessons from the Masters" includes a brilliant body of recognized leaders in astronomical imaging, assembled by Robert Gendler, who delivers the most current, sophisticated and useful information on digital enhancement techniques in astrophotography available today. Each chapter focuses on a particular technique, but the book as a whole covers all types of astronomical image processing, including processing of events such as eclipses, using DSLRs, and deep-sky, planetary, widefield, and high resolution astronomical image processing. Recognized contributors include deep-sky experts such as Jay GaBany, Tony Hallas, and Ken Crawford, high-resolution planetary expert Damian Peach, and the founder of TWAN (The World at Night) Babak A. Tafreshi. A large number of illustrations (150, 75 in color) present the challenges and accomplishments involved in the processing of astronomical images by enthusiasts.

The 24th century: humankind has become a spacefaring civilization, colonizing the solar system and beyond. While no alien forms of life have yet been encountered in this expansion into space, colonists suddenly encounter machines of alien origin - huge robots able to reproduce themselves. Called replicators by the colonists, they seem to have but a single goal: to destroy all organic life they come in contact with.
Since the colonial governments have no means to fight this menace directly, they instead promise huge rewards to whoever destroys a replicator. As a result, the frontier attracts a new kind of adventurers, the Hunters, who work to find and destroy the replicators. Mike Edwards, a skilled young maintenance technician and robotics expert at a faraway outpost, will not only become one of them - but be the very first one to unlock the secret behind the replicators origin and mission.
The scientific and technical aspects underlying the plot - in particular space travel, robotics and self-replicating spacecraft - are introduced and discussed by the author in an extensive non-technical appendix."

Fora general audience interested insolving mysteries in art, history, and literature using the methods of science, 'forensic astronomy' is a thrilling new field of exploration. Astronomical calculations are the basis of the studies, which have the advantage of bringing to readers both evocative images and a better understanding of the skies.
Weather facts, volcano studies, topography, tides, historical letters and diaries, famous paintings, military records, and the friendly assistance of experts in related fields add variety, depth, and interest to the work. The chosen topics are selected for their wide public recognition and intrigue, involving artists such as Vincent van Gogh, Claude Monet, Edvard Munch, and Ansel Adams; historical events such as the Battle of Marathon, the death of Julius Caesar, the American Revolution, and World War II; and literary authors such as Chaucer, Shakespeare, Joyce, and Mary Shelley. This book sets out to answer these mysteries indicated with the means and expertise of astronomy, opening the door to a richer experience of human culture and its relationship with nature.
Each subject is carefully analyzed. As an example using the study of sky paintings by Vincent van Gogh, the analytical method would include:
- computer calculations of historical skies above France in the 19th century
- finding and quoting the clues found in translations of original letters by Van Gogh
- making site visits to France to determine the precise locations when Van Gogh set up his easel and what celestial objects are depicted.
For each historical event influenced by astronomy, there would be a different kind of mystery to be solved. As an example:
- How can the phase of the Moon and time of moonrise help to explain a turning point of the American Civil War - the fatal wounding of Stonewall Jackson at Chancellorsville in 1863?
For each literary reference to astronomy, it was determined which celestial objects were being described and making an argument that the author is describing an actual event. For example, what was the date of the moonlit scene when Mary Shelley first had the idea for her novel Frankenstein?

These and more fun riddles will enchant and delight the fan of art and astronomy. "

This book introduces the Martian simulations of The Mars Society, the first one installed on Devon Island, an uninhabited island in the Canadian Arctic, well within the polar circle, and the second in the desert of Utah, several hundreds of kilometers South of Salt Lake City. The book is based on the diaries held during the simulations, by Vladimir Pletser, a physicist-engineer, who was selected to participate in these simulations. It relates the details of everyday life in these Martian habitats and of the scientific and exploratory work conducted in these extreme environments in preparation for future manned missions to Mars. Through the real experiences described in the book, readers will find space explorations and living on Mars more tangible.

Many books have been written about the Big Bang and how the universe became the way it is today. But what about the future of the universe? What will happen to the Earth and solar system? What about our galaxy? Indeed, how long will the universe as we recognize it survive? The Future of the Universe takes the reader on a journey through space and time, beginning with a long look at the Earth and solar system, voyaging to the outermost galaxies, and finishing with speculations about the life and fate of the entire universe.

Federal patronage of science was never contemplated by the framers of the Constitution, but they did seek to "promote the Progress of Science and useful Art" by granting inventors patent rights. However, direct subvention to scientists and scientific organizations was not considered appropriate activity of the central government. In the 19th Century, American science was funded almost entirely through private investors. Since WWII, however, the federal government has become the primary patron of American science. From the race-to-space in the 1950s to current furor over global warming, Bennett traces the subtle and not-so-subtle ways in which government has co-opted scientific research and reinforced a culture in which challengers to proscribed wisdom are frozen out. Citing original documents and media reports, Bennett offers a compelling, entertaining, and thought-provoking perspective on political influence on scientific research and its implications for a democratic society.

"During the Nineteenth Century, almost entirely on private funding, American science grew from practically nothing to world class. Now, however, over fifty percent of American science is funded by the federal government. Dr. Bennett traces the path, "crisis" after "crisis," by which American science became practically an arm of the federal government. His tale is a cautionary one, warning against future "crisis mongers" who would extend the government's already majority control of American science even further. His warning is a timely one, and it should be heeded." Joseph P. Martino, author of Science Funding: Politics and Porkbarrel

"Bennett's latest book offers a challenging interpretation of the rise of the American federal science establishment since World War II. Focusing primarily on the growth of the space program, Bennett argues that crisis, real or imagined, is the source of state power and state funding for science. The Doomsday Lobby offers what no doubt will be viewed as a controversial contribution to the history of American science policy, and more broadly to an understanding of the role of the state in society." James D. Savage, Professor of Politics, University of Virginia, and author of Funding Science in America

Two thousand years ago, according to the Bible, a star rose low in the east and stopped high above Bethlehem. Was it a miracle, a sign from God to herald the birth of Christ? Was there a star at all, or was it simply added to the Bible to fulfill the Old Testament prophecy concerning the birth of the Messiah? Or was the Star of Bethlehem an actual astronomical event? For hundreds of years, astronomers as prominent as Johannes Kepler have sought an answer to this last baffling question. In The Star of Bethlehem, Mark Kidger brings all the tools of modern science, years of historical research, and an infectious spirit of inquiry to bear on the mystery. He sifts through an astonishing variety of ideas, evidence, and information--including Babylonian sky charts, medieval paintings, data from space probes, and even calculations about the speed of a camel--to present a graceful, original, and scientifically compelling account of what it may have been that illuminated the night skies two millennia ago. Kidger begins with the stories of early Christians, comparing Matthew's tale of the Star and the three Magi who followed it to Bethlehem with lesser-known accounts excluded from the Bible. Crucially, Kidger follows the latest biblical scholarship in placing Christ's birth between 7 and 5 B.C., which leads him to reject various phenomena that other scientists have proposed as the Star. In clear, colorful prose, he then leads us through the arguments for and against the remaining astronomical candidates. Could the Star have been Venus? What about a meteor or a rare type of meteor shower? Could it have been Halley's Comet, as featured in Giotto's famous painting of the Nativity? Or, as Kidger suspects, was the Star a combination of events--a nova recorded in ancient Chinese and Korean manuscripts preceded by a series of other events, including an unusual triple conjunction of planets? Originally published in 1999. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press.

Advance praise for Philip Plait’s Bad Astronomy

"Bad Astronomy is just plain good! Philip Plait clears up every misconception on astronomy and space you never knew you suffered from." —Stephen Maran, Author of Astronomy for Dummies and editor of The Astronomy and Astrophysics Encyclopedia

"Thank the cosmos for the bundle of star stuff named Philip Plait, who is the world’s leading consumer advocate for quality science in space and on Earth. This important contribution to science will rest firmly on my reference library shelf, ready for easy access the next time an astrologer calls." —Dr. Michael Shermer, Publisher of Skeptic magazine, monthly columnist for Scientific American, and author of The Borderlands of Science

"Philip Plait has given us a readable, erudite, informative, useful, and entertaining book. Bad Astronomy is Good Science. Very good science..." —James "The Amazing" Randi, President, James Randi Educational Foundation, and author of An Encyclopedia of Claims, Frauds, and Hoaxes of the Occult and Supernatural

"Bad Astronomy is a fun read. Plait is wonderfully witty and educational as he debunks the myths, legends, and 'conspiracies’ that abound in our society. 'The Truth Is Out There'–and it's in this book. I loved it!" —Mike Mullane, Space Shuttle astronaut and author of Do Your Ears Pop in Space?

Astronomers believe that a supernova is a massive explosion signaling the death of a star, causing a cosmic recycling of the chemical elements and leaving behind a pulsar, black hole, or nothing at all. In an engaging story of the life cycles of stars, Laurence Marschall tells how early astronomers identified supernovae, and how later scientists came to their current understanding, piecing together observations and historical accounts to form a theory, which was tested by intensive study of SN 1987A, the brightest supernova since 1006. He has revised and updated "The Supernova Story" to include all the latest developments concerning SN 1987A, which astronomers still watch for possible aftershocks, as well as SN 1993J, the spectacular new event in the cosmic laboratory.

Many ancient, even prehistoric, monuments and temples around the world show an amazingly sophisticated understanding of the heavens. They reflect this sacred knowledge in celestial alignments - to the eternal cycles of the sun, moon, stars and planets. The ceremonies performed at sites such as Stonehenge in England or Teotihuacan in Mexico are now lost to us. But the time-worn stones and structures remain, and archaeoastronomers (experts in ancient astronomy) have studied how their sightlines relate to astronomical phenomena such as midwinter or midsummer sunrise or the rising of the Pleiades star cluster. Within, Ken Taylor dives into the fantastical: The principles of astronomy - the seasons, the solstices and equinoxes, the rising and setting of stars, the "lunar standstills" Solar alignments - the language of light and shadow, and the life-giving shows of the sun Lunar alignments - the drama of the eclipse and the mysterious energies of the night Alignments to stars and planets - reaching out to the immensity of the cosmos In exploring such connections, in words, superb photographs and clear explanatory artworks, Celestial Geometry opens a whole universe of mystery and wonder, and a window on the inner life of ancient civilizations.

'Inspirational' Buzz Aldrin When exactly did life begin? What really happened during the big bang - and before it? Is the universe expanding? Is dark matter real? Do we live in one of many worlds? What's more, how can we prove any of this? This book is all about how we - any of us - can gain an understanding of the Universe in all its awe-inspiring glory. Brian Cox and Jeff Forshaw take us on an epic journey of scientific exploration, revealing how the biggest questions - from the size of the earth to the distance to the stars - are answerable from our own back gardens. You don't need a Large Hadron Collider or a Hubble Space Telescope to explore the cosmos. You just need this book.

In The Infinite Cosmos Joseph Silk takes the reader on a tour of the universe, past, present, and future, showing how the very latest observations and theories are unlocking clues about its origin and structure: X-ray, radio, and high-energy views of space are revealing fossil radiation left over from the big bang and providing us with unprecedented views of the most distant reaches of the universe. Theories from the frontiers of current research seek to explain its structure from the first moments to the present day, and we are beginning to understand its extraordinary nature and possible fate. This is a story involving the visible and the invisible; subatomic particles and unusual forces; long ages of darkness and spectacular and violent events. It tells of supernovae, dark matter, dark energy, curved spacetime, colliding galaxies, and supermassive black holes. Weaving the ideas of poets and writers as well as scientists into the story, from Kant and Keats to Einstein and Lemaitre, Silk explains our present state of knowledge, and how much more there is to understand about our infinite cosmos.

How well do you know our closest neighbour? Featured on BBC Radio 4 Saturday Live and BBC Breakfast The moon has fascinated humankind since the beginning of history. But far from being just a big rock out in space, the Moon has a phenomenal power over the earth, with its ability to create great waves, dictate the length of the day and summon the seasons. It is a key player in the story of our planet. In this unique celebration of the Moon, lunar expert and space scientist Dr Maggie Aderin Pocock takes readers on a journey through the Moon's past, present and future. She uncovers the way the Moon has captured our imaginations, contemplates how it was formed, and uncovers why we need the Moon to protect our fragile earth. Drawing on the latest scientific research, she then looks forward to what might be to come - will we return to the moon or will it become a launch pad to go into the great unknown? Filled with fascinating facts and anecdotes, and written with warmth and passion, The Book of the Moon is for scientists and stargazers alike. You'll never look at our closest neighbour in the same way again.

Follow Monte Ross of the Laser Space Signal Observatory as he explores the challenges in searching for evidence of extraterrestrials, the programs that have failed, and those that continue. The book circumvents the failure of searches at radio frequencies by being the first to explore electromagnetic frequencies besides RF and microwave as possible signal sources, taking into consideration all the ways that extraterrestrials might try to communicate with us. Throughout the presentation, all the ideas, concepts, and approaches are explained clearly, without the use of complex math or physics.

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.

Astronomy with a Budget Telescope, 2nd Edition is a complete introduction to buying and using a low-cost amateur astronomical telescope. It provides essential hints and tips about what to look for when buying on a budget - the best are now excellent value, but they all lack an astronomer's advice about setting them up and using them. Astronomy with a Budget Telescope was first published in 2003, since then technology has moved on substantially. The main factors are first the availability of fairly inexpensive computer-controlled "go-to" telescopes which after setting up can automatically locate any celestial objects with reasonable accuracy. Second, digital cameras have now almost completely displaced "wet" film cameras, and some of them are particularly well-suited to astronomical use. Third, prices are down and quality is up! This new edition is revised and extended to include using a low-cost "go-to" telescope - there are various pitfalls to be avoided - and how this class of instrument can make amateur astronomy more accessible to those with limited time at their disposal. It also discusses the new breed of mid-range digital cameras that include powerful on-board processing and image enhancement software that used to be available only to people with advanced astronomical CCD cameras. Finally, there are detailed reviews and test reports on some of the budget telescopes that are available on Main Street and by mail order.
