In meno di due decenni l'astronomia amatoriale ha cambiato volto. Il motivo, naturalmente, e il progresso tecnologico. Telescopi economici, ma di alta qualita, montature "go-to" controllate dal computer, autoguide, camere CCD, videocamere e (come sempre) computer e Internet sono soltanto alcuni degli elementi che hanno rivoluzionato l'astronomia del XXI secolo. Non solo hanno reso l'astronomia amatoriale piu "amichevole" e divertente, ma hanno anche ampliato enormemente le potenzialita dell'astrofilo.

Martin Mobberley dapprima affronta le tematiche di base per poi analizzare in modo approfondito quali sono gli strumenti disponibili sul mercato. Da qui prende le mosse per passare in rassegna le rivoluzionarie possibilita che si aprono per gli astrofili, dalla ripresa di immagini, alla spettroscopia, alla fotometria, alla sorveglianza degli oggetti Near-Earth - comete e asteroidi che possono avvicinarsi pericolosamente alla Terra.

L'astrofilo moderno e una valida guida alla nuova astronomia. Sia il neofita che chiede di essere introdotto in questo campo, sia l'astrofilo esperto che voglia tenersi al passo delle innovazioni troveranno in questo libro cio che fa per loro.

The Solar System - so what is it? We've all learned the basics at school but how much can you remember? Expert astronomers and co-presenters of The Sky at Night Chris North and Paul Abel take a fascinating guided tour of our Solar System and explain its wonders. They look at all the major players, including our more familiar neighbours - the Sun, the planets and their moons - the occasional visitors to our planet - asteroids, meteors and comets - as well as distant stars and what might be beyond our Solar System - Earth Mark II? Chris and Paul recount the history of how everything came about and the myths that once shaped astronomy. They explain the latest science and discoveries, and reveal how any amateur astronomer can view and interpret the Solar System.

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

The two most fascinating questions about extraterrestrial life are where it is found and what it is like. In particular, from our Earth-based vantage point, we are keen to know where the closest life to us is, and how similar it might be to life on our home planet. This book deals with both of these key issues. It considers possible homes for life, with a focus on Earth-like exoplanets. And it examines the possibility that life elsewhere might be similar to life here, due to the existence of parallel environments, which may result in Darwinian selection producing parallel trees of life between one planet and another. Understanding Life in the Universe provides an engaging and myth-busting overview for any reader interested in the existence and nature of extraterrestrial life, and the realistic possibility of discovering credible evidence for it in the near future.

This introduction to the night sky is for amateur astronomers who desire a deeper understanding of the principles and observations of naked-eye astronomy. It covers topics such as terrestrial and astronomical coordinate systems, stars and constellations, the relative motions of the sky, sun, moon and earth leading to an understanding of the seasons, phases of the moon, and eclipses. Topics are discussed and compared for observers located in both the northern and southern hemispheres. Written in a conversational style, only addition and subtraction are needed to understand the basic principles and a more advanced mathematical treatment is available in the appendices. Each chapter contains a set of review questions and simple exercises to reinforce the reader's understanding of the material. The last chapter is a set of self-contained observation projects to get readers started with making observations about the concepts they have learned. William Charles Millar, currently Professor of Astronomy at Grand Rapids Community College in Michigan, has been teaching the subject for almost twenty years and is very involved with local amateur astronomy groups. Millar also belongs to The Planetary Society and the Astronomical Society of the Pacific and has traveled to Europe and South America to observe solar eclipses. Millar holds a Masters degree in Physics from Western Michigan University.

Found throughout the universe, variable stars are fascinating objects to observe. Their brightness changes over time and they can easily be seen with even the most basic equipment. David Levy explains how to begin electronic (or CCD) observing, as well as how to observe variable stars through a small telescope or binoculars. Featuring a section on Southern hemisphere stars, this book covers various types of objects that can be observed by amateur astronomers, including more exotic phenomena like gamma ray bursts, blazars, and polars. It will motivate anyone with even a basic interest in astronomy to begin observing variable stars.

Galileo, Newton, Herschel, Huggins, Hale, Eddington, Shapley and Hubble: these astronomers applied ideas drawn from physics to astronomy and made dramatic changes to the world-pictures that they inherited. They showed that celestial objects are composed of the same materials as the earth and that they behave in the same way. They displaced successively the earth, the sun and finally the milky way galaxy from being the centre of the universe.
This book contains their biographies and outlines their greatest discoveries. Hard work, physical insight, desire for fame and a strong belief in the rightness of their own ideas were characteristics of all eight. Their often quirky personalities led them into bitter controversies with their contemporaries. But their successes arose from the outstanding clarity of their thoughts, their practical ability and their strong sense of direction in science.

The most beautiful and influential photographs ever made were of the whole earth seen from space. They were taken from the moon, almost as an afterthought, by the astronauts of the Apollo space programme. They inspired a generation to think more seriously about our responsibility for this tiny oasis in space, the 'blue marble' falling through empty darkness.

This is a book about the long road to the capture of those unforgettable images. It is a history of the space programme and of the ways in which it transformed our view of the earth and changed the lives of the astronauts who walked in space and on the moon. It is the story of the often blemished visionaries who inspired that journey into space: Charles Lindbergh, Robert Goddard and Wernher Von Braun, and of the courageous pilots who were the first humans to escape the Earth's orbit.

Both novice and advanced skywatchers will value this comprehensive and easy-to-use guide to the brilliant and ever-changing sights of the southern sky by night. Readers are introduced to the many and varied objects in the sky and their movements and changing appearances, as well as the ancient myths and legends entwined around the groupings of stars. Featured in this book are two groups of sky charts, designed so that readers can move easily between them. The 24 skyviews show the appearance of the whole night sky every two weeks (or at each hour of sidereal time). The 20 sky charts show particular areas of the night sky in detail and are accompanied by explanatory text. This new edition also features: - digitally re-drawn skyviews, sky charts and map of the surface of the Moon - a table of planet positions up to 2017

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.

Astronomer Joseph Silk explores the Universe from its beginnings to its ultimate fate. He demonstrates how cosmologists study cosmic fossils and relics from the distant past to construct theories of the birth, evolution and future of the Universe. Stars, galaxies, dark matter and dark energy are described, as successive chapters detail the evolution of the Universe from a fraction of a microsecond after the Big Bang. Silk describes how physicists apply theories of subatomic particles to recreate the first moments of the Big Bang, and how astronomers chart the vast depths of space to glimpse how the most distant galaxies formed. He gives an account of the search for dark matter and the dark energy that will determine the ultimate fate of the Universe. Joseph Silk is the Savilian Professor of Astronomy and Head of the Astrophysics Department at the University of Oxford. He was previously Professor of Astronomy at the University of California, Berkeley. He holds a BA in Mathematics from Clare College, Cambridge, and a PhD in Astronomy from Harvard University. Silk is the author, or co-author, of many books, including The Left Hand of Creation (Basic Books, 1994) and A Short History of the Universe (WH Freeman, 1997). He is a Fellow of the Royal Society, the American Physical Society, and the American Association for the Advancement of Science.

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.

For over a quarter of a century, gamma-ray bursts were the outstanding mystery in astronomy. No one knew where they were or how they worked. The Biggest Bangs tells how the mystery was unraveled, from the discovery of gamma-ray bursts by a Cold War satellite system monitoring the Nuclear Test Ban Treaty to the localization of bursts in distant galaxies and the observation of surprisingly bright flashes of light from the bursts themselves. The Biggest Bangs is for laymen with an interest in science, physicists and astronomers interested in subjects in those fields not their specialty, students in non-technical astonomy courses, and as supplemental reading for courses in the history of science.

The Sun is the closest star to Earth, and the only one we can observe in any sort of detail. As such it is a fascinating field of study, and one that is well-suited to amateur astronomers - the Sun is close enough to need little magnification. It also has the practical advantage, unlike every other astronomical object, of being visible in the daytime!During solar eclipses, there are momentary chances to observe and photograph some spectacular and scientifcally interesting sights.Studying the Sun nonetheless needs specialist knowledge. Safety is paramount, as without the right precautions the heat and light of the Sun would instantly blind the observer. But given the right techniques, the Sun is a rewarding subject for amateur astronomers: in this book, Professor Chris Kitchin provides all the information needed for safe solar observing.

The Ever-Changing Sky is a comprehensive and uniquely non-mathematical guide to spherical astronomy. In a clear and lucid text, it guides through terrestrial and celestial co-ordinate systems, time measurement and celestial navigation, on to the stars and constellations (with useful star maps provided), the motions and appearance of the Moon and planets, tides and eclipses, and the smaller bodies of the Solar System (asteroids, meteors, meteorites and comets). There is also a brief overview of atmospheric phenomena. This text is invaluable to students of naked-eye astronomy, amateur and professional astronomers, and more general readers wanting to know how the night sky changes.

This book summarizes and presents the scientific search for life in the universe, and the current level of scientific understanding of how life begins, grows, and becomes intelligent in our Solar System and beyond. This engaging book promises to appeal not only to the general reader but to scientists as well, many of whom strive to acquire an informed perspective on the search for extraterrestrial life in fields not their own.

If, as Immanuel Kant once said, we are guided by the starry sky above and the moral law within, then, thanks to David Levy, we can now conceptualize Kant's adage at least half-way. David Levy's Guide to the Night Sky is designed to satisfy observers who have just become interested in the sky and want to navigate their way around it. By stirring the imagination and putting observation in a framework of personal adventure, Levy explains how to discover the Moon, planets, comets, meteors, and distant galaxies through a small telescope. Fully updated, the new edition includes:

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.

Our Cosmic Origins tells the story of our remarkable adventure on this planet, beginning with a single event in the depths of space. It traces the rich and wonderful history of the Universe, from the Big Bang to the creation of atoms and molecules, from the formation of stars and planets to the emergence of life on Earth. Delsemme brings together cosmology, astronomy, geology, biochemistry, and biology to create a unique look at the complex story of the Universe. He chronicles how the first light atoms were made and formed stars and how heavier atoms were cooked in stars and scattered in space, creating dust mrains and organic molecules. He examines the growing eomplexity of plant and animal life, including the emergence and extinction of dinosaurs. Our Cosmic Origins shows how the coupling of eye and brain led to self-awareness and intelligence. It explores the cosmic coincidences that might explain our existence and concludes with the tantalizing suggestion that intelligent alien life is likely. This provocative book will appeal to anyone who has ever looked at the sky and wondered how we got here. Originally published in French, this edition has been revised to include the most recent research in astronomy and cosmology. Armand Delsemme has published four books and over 230 scientific papers. He received a Sigma Xi award for outstanding research and has had, by order of the International Astronomical Union, an asteroid named after him.
