Simone Marchi presents the emerging story of how cosmic collisions shaped both the solar system and our own planet, from the creation of the Moon to influencing the evolution of life on Earth. The Earth emerged out of the upheaval and chaos of massive collisions in the infancy of the Solar System, more than four billion years ago. The largest of these events sent into orbit a spray of molten rocks out of which the Moon coalesced. As in ancient mythological tales, this giant catastrophe marks the birth of our planet as we know it. Space exploration has shown that signs of ancient collisions are widespread in the Solar System, from the barren and once-habitable Mars to the rugged asteroids. On Earth these signs are more subtle, but still cataclysmic, such as the massive asteroid strike which likely sparked the demise of the dinosaurs and many other forms of life some 66 million years ago. Signatures of even more dramatic catastrophes are concealed in ancient rocks. These events wreaked havoc on our planet's surface, influencing global climate and topography, while also enriching the Earth with gold and other rare elements. And recently, modern science is finding that they could even have contributed to developing the conditions conducive to life. In Colliding Worlds, Simone Marchi explores the key role that collisions in space have played in the formation and evolution of our solar system, the development of planets, and possibly even the origin of life on Earth. Analysing our latest understanding of the surfaces of Mars and Venus, gleaned from recent space missions, Marchi presents the dramatic story of cosmic collisions and their legacies.

Furnished with more than a hundred figures, maps and tables, this book was first published in 1878 by Simon Newcomb (1835 1909), a noted mathematician and professor at the United States Naval Observatory. A meticulous work, originally intended to be of use to the general reader as well as the student, it provides a view of astronomy as it stood on the eve of General Relativity, and inevitably includes some theories which have since been disproved. Newcomb outlines a brief history of astronomy, from ancient Greece (when the planets were thought to be fixed in crystal spheres), to the application of the new laws of thermodynamics and the latest observations of the solar system. Included are a rejection of the then prevalent theory that the sun has a cool interior and its own inhabitants, details of the anomaly of Mercury's orbit according to Newtonian theory, and thorough observational guides.

Originally published during the early part of the twentieth century, the Cambridge Manuals of Science and Literature were designed to provide concise introductions to a broad range of topics. They were written by experts for the general reader and combined a comprehensive approach to knowledge with an emphasis on accessibility. First published in 1914, R. A. Sampson's book The Sun presents an early twentieth-century overview of the facts, theories and astronomical phenomena relating to the Sun.

Considering the development of life on Earth, the existence of life in extreme environments and the potential for life elsewhere in the Universe, this book gives a fascinating insight into our place in the Universe. Chris Impey leads the reader through the history, from the Copernican revolution to the emergence of the field of astrobiology - the study of life in the cosmos. He examines how life on Earth began, exploring its incredible variety and the extreme environments in which it can survive. Finally, Impey turns his attention to our Solar System and the planets beyond, discussing whether there may be life elsewhere in the Universe. Written in non-technical language, this book is ideal for anyone wanting to know more about astrobiology and how it is changing our views of life and the Universe. An accompanying website available at www.cambridge.org/9780521173841 features podcasts, articles and news stories on astrobiology.

A gripping first-person account of how scientists came to understand our universe's mysterious structure J. Richard Gott was among the first cosmologists to propose that the structure of our universe is like a sponge made up of clusters of galaxies intricately connected by filaments of galaxies-a magnificent structure now called the "cosmic web" and mapped extensively by teams of astronomers. Here is his gripping insider's account of how a generation of undaunted theorists and observers solved the mystery of the architecture of our cosmos. The Cosmic Web begins with modern pioneers of extragalactic astronomy, such as Edwin Hubble and Fritz Zwicky. It goes on to describe how, during the Cold War, the American school of cosmology favored a model of the universe where galaxies resided in isolated clusters, whereas the Soviet school favored a honeycomb pattern of galaxies punctuated by giant, isolated voids. Gott tells the stories of how his own path to a solution began with a high-school science project when he was eighteen, and how he and astronomer Mario Juric measured the Sloan Great Wall of Galaxies, a filament of galaxies that, at 1.37 billion light-years in length, is one of the largest structures in the universe. Drawing on Gott's own experiences working at the frontiers of science with many of today's leading cosmologists, The Cosmic Web shows how ambitious telescope surveys such as the Sloan Digital Sky Survey are transforming our understanding of the cosmos, and how the cosmic web holds vital clues to the origins of the universe and the next trillion years that lie ahead.

The cosmos is a very big place indeed and most people find it rather too enormous. Hence, this very small book takes the reader on a clever little journey through it all. Packed with information on everything from Supernovae to Galaxy Clusters and Black Holes, as well as all the latest theories about how it might have come into being, this is probably the densest, and certainly the greenest book ever written on the Universe in the Universe. It is printed in sepia inks on 100 per cent recycled papers.

Are humans a galactic oddity, or will complex life with human abilities develop on planets with environments that remain habitable for long enough? In a clear, jargon-free style, two leading researchers in the burgeoning field of astrobiology critically examine the major evolutionary steps that led us from the distant origins of life to the technologically advanced species we are today. Are the key events that took life from simple cells to astronauts unique occurrences that would be unlikely to occur on other planets? By focusing on what life does - it's functional abilities - rather than specific biochemistry or anatomy, the authors provide plausible answers to this question. Systematically exploring the various pathways that led to the complex biosphere we experience on planet Earth, they show that most of the steps along that path are likely to occur on any world hosting life, with only two exceptions: One is the origin of life itself - if this is a highly improbable event, then we live in a rather "empty universe". However, if this isn't the case, we inevitably live in a universe containing a myriad of planets hosting complex as well as microbial life - a "cosmic zoo". The other unknown is the rise of technologically advanced beings, as exemplified on Earth by humans. Only one technological species has emerged in the roughly 4 billion years life has existed on Earth, and we don't know of any other technological species elsewhere. If technological intelligence is a rare, almost unique feature of Earth's history, then there can be no visitors to the cosmic zoo other than ourselves. Schulze-Makuch and Bains take the reader through the history of life on Earth, laying out a consistent and straightforward framework for understanding why we should think that advanced, complex life exists on planets other than Earth. They provide a unique perspective on the question that puzzled the human species for centuries: are we alone?

Jupiter is an extraordinarily colourful and dynamic planet. Over minutes, one can watch tiny shadows cast by its moons slide over its surface; over days and weeks parades of diverse, giant swirling storms can be seen to move and evolve. It is because of this richness of visual and physical properties that Jupiter has intrigued amateur and professional astronomers and has been the goal of several space missions. This highly illustrated volume provides a comprehensive and accessible account of Jupiter and its satellites. It reviews systematic telescopic observations that have stretched over more than a hundred years, in addition to modern observations and theories, and the wealth of data from the Pioneer, Voyager and Ulysses space missions. As well as a thorough survey of the planet's atmosphere, this volume presents an up-to-date account of our present knowledge of Jupiter's satellites and magnetosphere, at a level accessible to the non-specialist. This volume provides the definitive account of Jupiter for advanced amateur astronomers, professional astronomers and planetary scientists.

Astronomers have successfully observed a great deal of the Universe's history, from recording the afterglow of the Big Bang to imaging thousands of galaxies, and even to visualising an actual black hole. There's a lot for astronomers to be smug about. But when it comes to understanding how the Universe began and grew up we are literally in the dark ages. In effect, we are missing the first one billion years from the timeline of the Universe. This brief but far-reaching period in the Universe's history, known to astrophysicists as the 'Epoch of Reionisation', represents the start of the cosmos as we experience it today. The time when the very first stars burst into life, when darkness gave way to light. After hundreds of millions of years of dark, uneventful expansion, one by the one these stars suddenly came into being. This was the point at which the chaos of the Big Bang first began to yield to the order of galaxies, black holes and stars, kick-starting the pathway to planets, to comets, to moons, and to life itself. Incorporating the very latest research into this branch of astrophysics, this book sheds light on this time of darkness, telling the story of these first stars, hundreds of times the size of the Sun and a million times brighter, lonely giants that lived fast and died young in powerful explosions that seeded the Universe with the heavy elements that we are made of. Emma Chapman tells us how these stars formed, why they were so unusual, and what they can teach us about the Universe today. She also offers a first-hand look at the immense telescopes about to come on line to peer into the past, searching for the echoes and footprints of these stars, to take this period in the Universe's history from the realm of theoretical physics towards the wonder of observational astronomy.

This astronomy travel guide examines the many wonderful opportunities for experiencing the observing hobby. Amateur astronomy is often consigned to observing from home or from a local park, yet it can be much more. Tim Treadwell explores all the possibilities of astronomical and space-related activities that are available on day trips and longer vacations. These activities range from observatory visits and other simple ways to build an astronomy event into a holiday, to full blown specialized astronomy travel. Many trips give the opportunity to visit some of the world's famous attractions. On most vacations it can be a matter of just taking a day (or night) out of your schedule to fit in an astronomy event, but larger, dedicated pilgrimages are also possible. How to make the most of astronomy potential on a holiday, whether observing on the beach in Hawaii with the Telescope Guy or visiting Star City in Russia, is covered in detail. Go to a star party, explore the national parks or see the northern lights! There are a wide variety of activities for all budgets described in this book.

In September 1969, several months after the Apollo 11 lunar landing, President Richard M. Nixon established the Space Task Force to chart NASA's path for the decades to come. This imaginative vision was shattered less than six months later when, on January 13, 1970, NASA Administrator Dr. Thomas Paine announced that, owing to funding cuts, only the reusable Space Shuttle could be afforded -- there would be no space station, no return to the Moon, and no missions to Mars. This is a story never before told about the missions and technologies that NASA had begun to plan but never fully realized. The book is a companion to the author's previous two works on the Space Shuttle. Whereas the first two books showed how the Space Shuttle flew in space and what the program accomplished, this book explains what more the Space Shuttle could have achieved and how the space transportation system could have further matured if circumstances had been otherwise. A final chapter also discusses how some of these plans might be resurrected in future programs.

Indulge your curiosity with this humorous and fascinating book that demystifies the surprising myths about space.

In the latest book from the Everything You Know is Wrong series, Matt Brown brings you a compendium of amazing facts about our planet, the universe, and everything in between! Thanks to popular sci-fi films and TV shows, there have been many misconceptions about the cosmos – from travelling through worm-holes to blowing up asteroids. In Everything You Know About Space is Wrong, you'll find a plethora of myths, legends and misquotes that have shaped the way you view the universe today. Think that the vacuum of space would make your blood boil and your head explode? It won't, and there have been people who have survived without wearing a suit in space. Think that astronauts float in space because there is zero-gravity? They're actually constantly falling towards the Earth. Think that the colour of space is black? It's actually predominantly green.

Chock-full of facts about the cosmos, how it works (and how it doesn't!), this illuminating book will guide you through the mine of misinformation to answer such questions as whether we will meet aliens in our lifetime (SETI predicts we'll find evidence of ET by 2040!), what happens in the centre of the black hole, and why Mercury is not the hottest planet in the solar system. Discovering untruths about popular science, Everthing You Know About Space is Wrong provides a hugely entertaining insight into our universe.

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.
David H. Levy is one of the most successful comet hunters in history. He has discovered twenty-one, eight of them using a telescope in his own backyard.

Astronomical concepts can be truly hard to comprehend, especially those of planetary sizes and distances from Earth and from each other. These concepts are made more comprehensible by the group of illustrations in this book, which put scale extraterrestrial objects side by side with objects on Earth we can more easily relate to. For example, study the pictures of Earth floating above Jupiter's Great Red Spot and the asteroid Itokawa resting beside Toronto's CN Tower. These mind-bending images bring things better into perspective and will help you understand the size and scale of our Solar System. In later chapters, you will be told how close the visionaries of the past came to guessing what today's explorers would find. Astronomer/painter Lucien Rudaux's masterpieces of Mars dust storms anticipated Viking and Mars rover images by nearly a century. Space artist Ludek Pesek envisioned astronauts setting up camp on the lunar surface in scenes hauntingly similar to photos taken by Apollo astronauts decades later. But the real benefit of this work is in better grasping the nature of our universe -- how big it is, now large it is, and how we fit into it.

'Bite-sized, cutting edge science delivered with enormous enthusiasm - all you need to travel the cosmos' CHRIS LINTOTT 'A lot of astrophysics is packed into this neat little book . . . I guarantee you will come away knowing your dark matter from your supermassive black holes' JIM AL-KHALILI This book is for anyone who wants to easily understand the mind-blowing fundamentals of our extraordinary, expanding universe. Written by Oxford astrophysicist Dr Becky Smethurst and composed of ten captivating, simple essays, it guides you swiftly through the galaxies, explaining the mysteries of black holes, dark matter and what existed before the Big Bang, presenting the evidence as to whether we really are alone, illuminating what we still don't know, and much more besides. If you have big questions about Space, this book will provide you with the answers in an engaging and succinct way.

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.

If you always thought that it was Giovanni Schiaparelli who first coined the phrase 'Canali' pertaining to the straight lines he appeared to observe on Mars you'd be wrong. In 1858, an astronomer working at the Vatican observatory named father Pietro Angelo Secchi took it upon himself to create his own drawings of Mars. The red planet was now nearing a close approach to earth and the powerful Vatican telescope was capable of resolving detail previously invisible to most astronomers. Secchi thought he saw a series of straight lines on the Martian surface so he made an innocuous notation in his notes. His sketches and articles were published in 1859 in which he referred several times to 'Canale Atlantico' or 'Canale Ceruleo'. His regrettable choice of words would not have an impact for another eight years. This volume tells not only of people and places that have influenced mankind's relationship with the enigmatic red planet, but it also shows you the colour drawings that Secchi made, which were provided to us directly by the Vatican itself. Along with many other interesting stories, drawings and photographs this book will be a prize for both the novice or ardent student of Mars.

From the authors of Sketching the Moon comes a comprehensive guide filled with richly illustrated, detailed drawing tutorials that cover a variety of solar phenomena. Explanations of what to expect visually from white light, Hydrogen-alpha and Calcium K filters are provided for those new to solar observing, along with essential tips on equipment, observing techniques and the practicalities of drawing at the eyepiece. Time-honored, traditional methods and media are described in tandem with innovative techniques developed and shared by contemporary astronomical sketchers. For the technically minded, detailed descriptions are given on how to use image manipulation software to bring your sketches to life through animation. The Sun is the most visually dynamic object in our solar system and offers compelling, spectacular views. Knotted magnetic field lines give rise to powerful eruptions and form the intricate sunspots and arching prominences that make our nearest star one of the most exciting, yet challenging, astronomical objects to sketch. Facilitated by the availability of affordable dedicated solar telescopes and filters, the Sun has become an increasingly popular target amongst astronomical sketchers. The use of narrowband solar filters provides a wonderful opportunity to capture views of the Sun that have, until recently, been largely inaccessible. You'll discover easy to follow, step-by-step instructions geared toward your specific interests, be it technical sketching and contributing to science, personal study, or even fun solar outreach activities that help children learn through art. By using Solar Sketching as a reference, drawing the Sun has never been easier.

Observers no longer need to wonder what they will turn their attention to each night of the year with this updated text of a beloved favorite from Sir Partick Moore. His night-by-night account of the stars is the best possible guide an observer could ask for, and now includes the latest data for the years 2015-2020, preserving and extending Sir Patrick Moore's legacy. This new edition of his classic text makes it easy to see why Sir Patrick Moore was such a helpful guide to generations of budding astronomers, professional and amateur alike. For every night of the year Patrick gives the reader details of interesting objects that can be seen from Earth. It is a book for people with a wide interest in practical astronomy, those who may not have specialized in a specific area of astronomy and wish to expand their knowledge in all areas. Moore updated his book in a second edition in 2005, giving astronomical events through 2010, but a more current version has been desperately lacking. This third edition includes Sir Patrick's original text but revises its time-sensitive material and adds all of the points of interest that change from year to year, such as eclipses, occultations, planetary positions, and so on. Sir Patrick Moore left behind an enormous legacy, including the world's longest-running television series with the same original presenter, the BBC's The Sky at Night, and more than 70 written works. His influence on the world of amateur astronomy was phenomen al, and his knowledge and passion led many to take up observing as a life-long hobby. This book, "The Observer's Year, 366 Nights of the Universe" was, he said, one of his personal favorites. It now features a tribute to Patrick Moore's legacy as well as including what has changed in astronomy since the previous edition ten years ago.

This complete reference provides a wealth of practical information covering all aspects of amateur astronomy. Organized thematically for ease of use, it covers observing techniques, telescopes and observatories, internet resources, and the objects that can be studied. Those new to the field will find tips, techniques and plans on how to begin their quest, and more advanced observers will find useful advice on how to get more from their hobby. Michael E. Bakich obtained a bachelors degree in Astronomy from Ohio State University and a masters degree in Planetarium Education from Michigan State University. He has written numerous original planetarium programs, and gives lectures on astronomy to groups of all ages. He is also a tour guide to eclipses and astro-archaeological sites. Bakich has written two previous books: The Cambridge Planetary Handbook (2000) and The Cambridge Guide to the Constellations (1995), both published by Cambridge University Press.
