We present results from an adaptive optics survey conducted with the Palomar and Keck telescopes over 3 years, which measured the frequency of stellar and sub-stellar companions to Sun-like stars. The survey sample contains 266 stars in the 3-10000 million year age range at heliocentric distances between 8 and 200 parsecs and with spectral types between F5-K5. A sub-sample of 101 stars, between 3-500 million years old, were observed in deep exposures with a coronagraph to search for faint sub-stellar companions. A total of 288 candidate companions were discovered around the sample stars, which were re-imaged at subsequent epochs to determine physical association with the candidate host stars by checking for common proper motion. Benefitting from a highly accurate astrometric calibration of the observations, we were able to successfully apply the common proper motion test in the majority of the cases, including stars with proper motions as small as 20 milli-arcseconds/year. The results from the survey include the discovery of three new brown dwarf companions (HD 49197B, HD 203030B, and ScoPMS 214B), 43 new stellar binaries, and a triple system. The physical association of an additional, a priori-suspected, candidate sub-stellar companion to the star HII 1348 is astrometrically confirmed. The newly-discovered and confirmed young brown dwarf companions span a range of spectral types between M5 and T0.5, and will be of prime significance for constraining evolutionary models of young brown dwarfs and extra-solar planets. Based on the 3 new detections of sub-stellar companions in the 101 star sub-sample and following a careful estimate of the survey incompleteness, a Bayesian statisticalanalysis shows that the frequency of 0.012-0.072 solar-mass brown dwarfs in 30-1600 AU orbits around young solar analogs is 6.8% (-4.9%, +8.3%; 2-sigma limits). While this is a factor of 3 lower than the frequency of stellar companions to G-dwarfs in the same orbital range, it is significantly higher than the frequency of brown dwarfs in 0-3 AU orbits discovered through precision radial velocity surveys. It is also fully consistent with the observed frequency of 0-3 AU extra-solar planets. Thus, the result demonstrates that the radial-velocity "brown dwarf desert" does not extend to wide separations, contrary to previous belief.

Ever since early stargazers discovered that some heavenly bodies wandered among the others, people have been fascinated by the planets. Kepler calculated their orbits from naked-eye observations; Galileo's telescope made it possible to discern their markings; now observations from spacecraft provide electronically enhanced images that bring these distant worlds even closer. In Worlds in the Sky, William Sheehan gives us a history of this long fascination, weaving together scientific history, anecdotes surrounding planetary discoveries, and the personal reflections of an incurable amateur astronomer. He describes how we arrived at our current understanding of the Moon and the planets and shows how certain individuals in history shaped the world's knowledge about the Solar System. The University of Arizona Press's Century Collection employs the latest in digital technology to make previously out-of-print books from our notable backlist available once again. Enriching historical and cultural experiences for readers, this collection offers these volumes unaltered from their original publication and in affordable digital or paperback formats.

A selection of the History, Scientific American, and Quality Paperback Book Clubs For a very brief moment during the 1960s, America was moonstruck. Boys dreamt of being an astronaut; girls dreamed of marrying one. Americans drank Tang, bought "space pens" that wrote upside down, wore clothes made of space age Mylar, and took imaginary rockets to the moon from theme parks scattered around the country. But despite the best efforts of a generation of scientists, the almost foolhardy heroics of the astronauts, and 35 billion dollars, the moon turned out to be a place of "magnificent desolation," to use Buzz Aldrin's words: a sterile rock of no purpose to anyone. In Dark Side of the Moon, Gerard J. DeGroot reveals how NASA cashed in on the Americans' thirst for heroes in an age of discontent and became obsessed with putting men in space. The moon mission was sold as a race which America could not afford to lose. Landing on the moon, it was argued, would be good for the economy, for politics, and for the soul. It could even win the Cold War. The great tragedy is that so much effort and expense was devoted to a small step that did virtually nothing for mankind. Drawing on meticulous archival research, DeGroot cuts through the myths constructed by the Eisenhower, Kennedy, and Johnson administrations and sustained by NASA ever since. He finds a gang of cynics, demagogues, scheming politicians, and corporations who amassed enormous power and profits by exploiting the fear of what the Russians might do in space. Exposing the truth behind one of the most revered fictions of American history, Dark Side of the Moon explains why the American space program has been caught in a state of purposeless wandering ever since Neil Armstrong descended from Apollo 11 and stepped onto the moon. The effort devoted to the space program was indeed magnificent and its cultural impact was profound, but the purpose of the program was as desolate and dry as lunar dust.

On July 20, 1969, humanity paused with attention locked to television and radio broadcasts as the astronauts of the Apollo 11 mission dramatically touched down on the dusty face of the moon. The first word from the lunar surface: Houston. Houston, Space City USA is a visual celebration of the city's historic ties to the US human space program. When President Kennedy declared, ""We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard,"" he did so from the campus of Rice University. More than half a century later, Houston continues to serve as the nerve center of the American human space program. Author and photographer Ray Viator, a longtime Houstonian, has lovingly captured the spirit of a city's devotion to space exploration from then to now. Using striking photographs of the full moon as a visual motif of Houston's connection to spaceflight, Viator also weaves together historic images to show how former cow pastures transformed into mission control. Some connections are obvious-the Houston Astros or the Houston Rockets. Others are hidden in plain sight, like the arm patches on the uniform of every Houston police officer that read, ""Space City U.S.A."" Viator's lens captures this and more. Houston, Space City USA not only marks the important milestone of the first lunar landing, but it also helps readers discover and rediscover a city's constellation of connections to one of humankind's greatest achievements.

Although the author's inquiries are still incomplete, he brought together some of the notes he had collected, as they may induce other inquirers to go on with the work. The reader must form his own judgment as to the direction in which the evidence tends. Lockyer believed the view that our ancient monuments were built to observe and mark the rising and setting places of the heavenly bodies is now fully established with the evidence.

"A fascinating and useful handbook to both the science and science fiction of extraterrestrial life. Cohen and Stewart are amusing, opinionated, and expert guides. I found it a terrific and informative piece of work–nothing else like it!"
–Greg Bear

"I loved it."
–Larry Niven

"Ever wonder about what aliens could be like? The world authority is Jack Cohen, a professional biologist who has thought long and hard about the vast realm of possibilities. This is an engaging, swiftly moving study of alien biology, a subject with bounds and constraints these authors plumb with verve and intelligence."
–Gregory Benford

"A celebration of life off Earth. A hearteningly optimistic book, giving a much-needed antidote to the pessimism of astrobiologists who maintain that we are alone in the universe–a stance based on a very narrow view of what could constitute life. A triumph of speculative nonfiction."
–Dougal Dixon, author of
After Man: A Zoology of the Future

This volume of star names is not intended for the professional astronomer, but as a reference to fill a vacancy in popular astronomical literature. It contains a sketch of the lunar and solar zodiacs which are constantly alluded to in the treating of individual constellations; as well as a detailed list of the constellations, their history among the nations, cataloging and early treatment by authors and their connection with astrology, art, folklore, literature and religion.

An amazing journey from our moon to the most distant stars, revealing the magic and majesty of our universe.

There are as many different kinds of stars as there are stars themselves. Each an individual, every one unique. In this arresting and lavishly illustrated volume, noted astronomy writer and teacher Jim Kaler choose 100 stars to illustrate the mind-boggling variety of the stars' shapes and sizes, their immense ages, and the vast range of configurations in which they exist.||From AG Draconis to Z Andromedae, this alphabetically arranged volume first lists each star's resident constellation, its class, its apparent brightness as viewed from Earth, its distance from our Sun, and its visual luminosity. Then the real story begins. In choosing his "top 100," Kaler has aimed not just at providing a representative sample of the Universe's extraordinarily diverse population, but at capturing their complexity, their dynamism, and the amazing view they provide into the extraordinary physical forces at play in the Universe.||James B. Kaler is Professor of Astronomy at the University of Illinois at Urbana-Champaign. He has held both Fulbright and Guggenheim Fellowships, and has been awarded medals for his work from the University of Liege (Belgium) and the University of Mexico.

Recent discoveries of planet-like objects circling other sun-like stars have stirred enormous interest in what other planets may exist in the universe, and whether they could support intelligent life. This book takes us into the midst of this search for extrasolar planets. Unlike other books, it focuses on the people behind the searches -- many known personally by the author -- and the extraordinary technology that is currently on the drawing boards. The author is an experienced, award-winning science journalist who was previously technology correspondent for the Financial Times of London. He has written on many topics in astronomy and astrobiology in over 35 different newspapers and magazines worldwide.

Skywatchers of Ancient Mexico helped establish the field of archaeoastronomy, and it remains the standard introduction to this subject. Combining basic astronomy with archaeological and ethnological data, it presented a readable and entertaining synthesis of all that was known of ancient astronomy in the western hemisphere as of 1980.

In this revised edition, Anthony Aveni draws on his own and others' discoveries of the past twenty years to bring the Skywatchers story up to the present. He offers new data and interpretations in many areas, including:
-- The study of Mesoamerican time and calendrical systems and their unprecedented continuity in contemporary Mesoamerican culture
-- The connections between Precolumbian religion, astrology, and scientific, quantitative astronomy
-- The relationship between Highland Mexico and the world of the Maya and the state of Pan-American scientific practices
-- The use of personal computer software for computing astronomical data

With this updated information, Skywatchers will serve a new generation of general and scholarly readers and will be useful in courses on archaeoastronomy, astronomy, history of astronomy, history of science, anthropology, archaeology, and world religions.

Winner of several teaching awards, including National Professor of the Year from the Council for the Advancement and Support of Education, Anthony F. Aveni is the Russell B. Colgate Professor of Astronomy and Anthropology at Colgate University in upstate New York.

The first photo book by the Nasa astronaut Scott Kelly, who spent a record-breaking Year in Space. This is an awe-inspiring collection of the photos Scott took himself while on board the International Space Station, many of which have never been seen before. Scott Kelly has seen the world in ways most of us never will. During his record-breaking 340 consecutive days on board the ISS, Scott Kelly circled the earth 5,440 times, witnessing 10,944 sunrises and sunsets - that's 16 a day. In all this time, he posted just 713 photos on Instagram. But it's not all sunrises, sunsets and #nofilter. Through the photos Kelly took during his time in space, we can learn to see the world in a new way and we are afforded a glimpse into a life that most of us will never encounter but of which many of us dream. This book will show you what it's really like to be a Nasa astronaut.

Popular cosmologist Martin Rees of Cambridge University traces the essential features of the physical cosmos to six numbers imprinted in the Big Bang, and argues that if a single one were untuned, there would be no stars and no life.

Gateway to the Moon presents the definitive history of the origins, design, and construction of the lunar launch facilities at Kennedy Space Center, the terrestrial site of one of the greatest national adventures of the 20th century, humanity's first trip to the moon. It includes archival illustrations and diagrams of locations, personnel, and equipment, from aerial views of sandy, undeveloped Cape Canaveral to some of the first photos of the mobile launchers and crawler-transporters.

Filled with the sense of wonder and pride that the earliest U.S. space achievements inspired, the book focuses on launch complexes 39A and 39B, the gigantic assemblies from which the Apollo-Saturn vehicles departed for trips into space, and on the massive eight-acre Vertical Assembly Building (renamed the Vehicle Assembly Building) and the attached Launch Control Center -- some of the most awesome buildings ever constructed. It also analyzes the technological and governmental interactions necessary to ensure success of the launches.

Originally part of Moonport, a 1978 volume in the NASA History Series, the book is based on extensive interviews with wit participants in the space program and wide access to official documents, letters, and memoranda; in addition, the authors air criticisms directed at the Kennedy Space Center team and treat in detail mistakes in launch operations and conflicts within the program. Written for a general-interest audience, with jargon and acronyms translated into everyday language, the book offers a faithful account of technology in service to humanity.

"A highly readable survey of the historical prelude to the study of the origins of life, as well as selected areas of current research, including the search for extraterrestrial life."-NatureWhere did we come from? Did life arise on earth or on some other planet? What did the earliest primitive organisms look like? Untangling a century of contentious debate, the authors explore current theories of the source of life-from Martian meteors to hydrothermal vents-and then present their own elegant scenario: Life arose not in the subterranean depths, as many believe, but on Earth's tumultuous surface, where a primitive form of natural selection spawned the first genetic material, perhaps in the form of a proto-virus. Knowing exactly how life began on Earth will not only teach us more about ourselves, it will bring us closer to finding life elsewhere.

'Sarah Cruddas is a gifted writer and Look Up is an inspired book. I am hopeful that we will never stop looking up.' Apollo 11 astronaut Michael Collins Most of us have never been to space. To date, of the more than 100 billion humans that have ever existed, fewer than 600 humans have ever left Earth. But the exploration of space is the most significant thing we will ever do as a species. Sarah Cruddas has been looking to the skies her entire life. Her childhood was spent staring at the Moon and hearing stories of the space race, and she worked in a fruit factory to fund her love of the subject. Her subsequent career studying astrophysics, and becoming a television host and space journalist has seen her report on space exploration and chase launches across the world. In Look Up Sarah explains why she has always been a passionate advocate for why space should matter - to everyone. From our ancestors who first painted patterns of the stars in caves, to the US and Soviet pioneers who first forged a path beyond our planet, Sarah Cruddas explores the stories and sacrifices that humankind has made to understand more about our place in the universe. And even today, when Moon walking and people in space suits seem less relevant to us than climate change and conflicts here on Earth, she shows how everything from medicine to mobile phones is affected by space technology, and how a new generation of entrepreneurs have kick-started a new story with the stars. This is an inspirational and enlightening introduction to the importance of space to everyone, and why we should all learn to Look Up.

Former NASA astrophysicist Jeanne Cavelos examines the scientific possibility of the fantastical world of Star Wars. She explains to non-technical readers how the course of science might soon intersect with such fantasies as interstellar travel, robots capable of thought and emotion, habitable alien planets, bizarre intelligent life forms, high-tech weapons and spacecraft, and advanced psychokinetic abilities. She makes complex physics concepts, like quantum mechanics, wormholes, and Einstein's theory of relativity both fascinating and easy to comprehend. The Science of Star Wars does for Star Wars what Lawrence Krauss's bestselling The Physics of Star Trek did for the Star Trek universe.

Cavelos answers questions like:

* How might spaceships like the Millennium Falcon make the exhilarating jump into hyperspace?

* Could a single blast from the Death Star destroy an entire planet?

* How close are we to creating robots that look and act like C-3PO and R2-D2?

* Could light sabers possibly be built, and if so, how would they work?

* Do Star Wars aliens look like "real" aliens might?

* What kind of environment could spawn a Wookie?

* What would living on a desert planet like Tatooine be like?

* Why does Darth Vader require an artificial respirator?

* Can we access a "force" with our minds to move objects and communicate telepathically with each other?

Donna Shirley's 35-year career as an aerospace engineer reached a jubilant pinnacle in July 1997 when Sojourner--the solar-powered, self-guided, microwave-oven-sized rover--was seen exploring the Martian landscape in Pathfinder's spectacular images from the surface of the red planet. The event marked a milestone in space, but for Donna Shirley, the leader of the mostly male team that designed and built Sojourner--and the first woman ever to manage a NASA program--it marked a triumph of another kind.

Managing Martians is Shirley's captivating memoir of a life and career spent reaching for the stars. From her seemingly outlandish aspiration at age ten to build aircraft, to abandoning high school Home Ec in favor of mechanical drawing, and, at sixteen, becoming a licensed pilot, Shirley defied expectations from the beginning. In a vivid narrative, rich with anecdotes and thrilling turning points, Shirley recounts the intense battles she waged to defend her vision and the ingenuity and resourcefulness of her committed team. Her moment-by-cliffhanging-moment account of Pathfinder's landing and Sojourner's first tentative foray across the sands of Mars brilliantly captures the fulfillment of a lifelong dream as it heralds a brave new era of space exploration.

Developments in the interrelated industries surrounding air transportation and space exploitation continue to give rise to new and challenging problems in international law. As more and more countries and private entities use outer space for satellite-based systems of air navigation, telecommunications, and surveillance, significant economic and environmental issues loom ever larger. Moreover, the ongoing exploration of space and celestial bodies in search of commercial possibilities poses new questions, ranging in substance from the proliferation of space debris to intellectual property rights. The Warsaw System of intercarrier liability, although still serviceable, is severely strained by such developments as the products liability of aircraft and satellite manufacturers and the liability involved in the construction and launching of space stations and multipurpose satellites. Aware of the massive convergence of these legal and political challenges, over 200 air and space experts - from the airlines and aerospace industries, from law practice and law faculties, and from civil aviation authorities at national, regional, and international levels - met in Seoul, in June 1997, to search for solutions and to promote and strengthen international co-operation in this crucial sphere. Twenty-three countries were represented. This book is the record of their presentations, discussions, recommendations, and conclusions. The many specific issues and topics raised and analyzed include the phenomenon of trade in launch services; the interdependence of military and satellite systems; new remote sensing technologies and the challenges they present to the Outer Space Treaty of 1967; new airports; the transfer of air traffic control functions; the transnational co-production of aircraft; regional and bilateral air transport agreements; and a great deal more. Numerous cases from a variety of jurisdictions are cited, so that the reader may gain a sense of jurisprudential trends in air and space law as we proceed into the 21st Century.

In 1992 the fastest object known to mankind hit the Earth's atmosphere at a speed within a billion-trillionth of one percent of the speed of light, carrying an energy far above that of the most powerful particle accelerator ever built. That object was a cosmic ray.Over 100 cosmic ray particles pass through our bodies every second. Some of these have enormous energies, far above those accessible using man-made particle accelerators. Many of them have traveled millions of light years across the Universe, and they bring with them clues about exotic astronomical systems like neutron stars, supernovae, quasars, and black holes.In "Cosmic Bullets" leading cosmic ray experts Roger Clay and Bruce Dawson tell the incredible story of the discovery and study of these messengers from deep space. They point out that despite a century of intensive research, it is still far from certain where most cosmic rays come from or how they were created. Nevertheless, the little-known story of their discovery and subsequent study holds many sudden twists and wonderful surprises. The authors have captured the excitement and mystery of astrophysical research, and the human drama of science, in this story of discovery.

This work is an account of one of the most thrilling topics in science - the search for life on Mars - and how it may ultimately lead us to the origins of life in the universe. Hidden beneath the sterile surface of Earth's neighbouring planet may be the keys to unlocking the origins of life in the universe. An expert on extreme-life environments, Malcolm Walter argues that the best place to find evidence of life on Mars is in the rocks and subsurface water of the Red Planet - out of reach of telescopes and space probes. In this book, Walter unveils his dramatic plan - already adopted by NASA - for finding these elusive traces of life.

A wonderful novel and perfect book club choice, The Right Stuff is a wildly vivid and entertaining chronicle of America's early space programme. WITH AN INTRODUCTION BY US ASTRONAUT SCOTT KELLY 'What is it,' asks Tom Wolfe, 'that makes a man willing to sit on top of an enormous Roman Candle...and wait for someone to light the fuse?' Arrogance? Stupidity? Courage? Or, simply, that quality we call 'the right stuff'? A monument to the men who battled to beat the Russians into space, The Right Stuff is a voyage into the mythology of the American space programme, and a dizzying dive into the sweat, fear, beauty and danger of being on the white-hot edge of history in the making. 'Tom Wolfe at his very best... Learned, cheeky, risky, touching, tough, compassionate, nostalgic, worshipful, jingoistic...The Right Stuff is superb' New York Times Book Review
