Studies of stars and stellar populations, and the discovery and characterization of exoplanets, are being revolutionized by new satellite and telescope observations of unprecedented quality and scope. Some of the most significant advances have been in the field of asteroseismology, the study of stars by observation of their oscillations. Asteroseismic Data Analysis gives a comprehensive technical introduction to this discipline. This book not only helps students and researchers learn about asteroseismology; it also serves as an essential instruction manual for those entering the field. The book presents readers with the foundational techniques used in the analysis and interpretation of asteroseismic data on cool stars that show solar-like oscillations. The techniques have been refined, and in some cases developed, to analyze asteroseismic data collected by the NASA Kepler mission. Topics range from the analysis of time-series observations to extract seismic data for stars to the use of those data to determine global and internal properties of the stars. Reading lists and problem sets are provided, and data necessary for the problem sets are available online. The first book to describe in detail the different techniques used to analyze the data on stellar oscillations, Asteroseismic Data Analysis offers an invaluable window into the hearts of stars. * Introduces the asteroseismic study of stars and the theory of stellar oscillations* Describes the analysis of observational (time-domain) data* Examines how seismic parameters are extracted from observations* Explores how stellar properties are determined from seismic data* Looks at the "inverse problem," where frequencies are used to infer internal structures of stars

Delineating the huge strides taken in cosmology in the past ten years, this much-anticipated second edition of Malcolm Longair's highly appreciated textbook has been extensively and thoroughly updated. It tells the story of modern astrophysical cosmology from the perspective of one of its most important and fundamental problems - how did the galaxies come about? Longair uses this approach to introduce the whole of what may be called "classical cosmology". What's more, he describes how the study of the origin of galaxies and larger-scale structures in the Universe has provided us with direct information about the physics of the very early Universe.

This book contains the elaborated and updated versions of the 24 lectures given at the 43rd Saas-Fee Advanced Course. Written by four eminent scientists in the field, the book reviews the physical processes related to star formation, starting from cosmological down to galactic scales. It presents a detailed description of the interstellar medium and its link with the star formation. And it describes the main numerical computational techniques designed to solve the equations governing self-gravitating fluids used for modelling of galactic and extra-galactic systems. This book provides a unique framework which is needed to develop and improve the simulation techniques designed for understanding the formation and evolution of galaxies. Presented in an accessible manner it contains the present day state of knowledge of the field. It serves as an entry point and key reference to students and researchers in astronomy, cosmology, and physics.

Will the universe expand forever? Or will it collapse in a Big Crunch within the next few billion years? If the Big Bang theory is correct in presenting the origins of the universe as a smooth fireball, how did the universe come to contain structures as large as the recently discovered "Great Wall" of galaxies, which stretches hundreds of millions of light years? Such are the compelling questions that face cosmologists today, and it is the excitement and wonder of their research that Michael Lemonick shares in this lively tour of the current state of astrophysics and cosmology. Here we visit observatories and universities where leading scientists describe how they envision the very early stages, the history, and the future of the universe. The discussions help us to make sense of many recent findings, including cosmic ripples, which supply evidence of the first billionth of a second of the universe; anomalous galactic structures such as the Great Wall, the Great Void, and the Great Attractor; and the mysterious presence of dark matter, massive but invisible. Lemonick assembles this information into a comprehensive, up-to-date picture of modern cosmology, and a portrait of its often contentious practitioners. Originally published in 1995. 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.

The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. Developing ideas sketched in the first volume, twistor theory is now applied to genuine issues of physics, and there are the beginnings of twistor diagram theory (an analogue of Feynman Diagrams). This collection includes joint papers with Stephen Hawking, and uncovers certain properties of black holes. The idea of cosmic censorship is also first proposed. Along completely different lines, the first methods of aperiodic tiling for the Euclidean plane that come to be known as Penrose tiles are described. This volume also contains Penrose's three prize-winning essays for the Gravity Foundation (two second places with both Ezra Newman and Steven Hawking, and a solo first place for 'The Non-linear graviton').

What is time? The Janus Point offers a ground-breaking solution to one of the greatest mysteries in physics. For over a century, the greatest minds have sought to understand why time seems to flow in one direction, ever forward. In The Janus Point, Julian Barbour offers a radically new answer: it doesn't. At the heart of this book, Barbour provides a new vision of the Big Bang - the Janus Point - from which time flows in two directions, its currents driven by the expansion of the universe and the growth of order in the galaxies, planets and life itself. What emerges is not just a revolutionary new theory of time, but a hopeful argument about the destiny of our universe. 'Both a work of literature and a masterpiece of scientific thought' Lee Smolin, author of The Trouble with Physics 'Profound...original...accessible to anyone who has pondered the mysteries of space and time' Martin Rees, Astronomer Royal 'Takes on fundamental questions, offering a new perspective on how the Universe started and where it may be headed' Science Magazine

Orienting us with an insider's tour of our cosmic home, the Milky Way, William Waller and Paul Hodge then take us on a spectacular journey, inviting us to probe the exquisite structures and dynamics of the giant spiral and elliptical galaxies, to witness colliding and erupting galaxies, and to pay our respects to the most powerful galaxies of all-the quasars. A basic guide to the latest news from the cosmic frontier-about the black holes in the centers of galaxies, about the way in which some galaxies cannibalize each other, about the vast distances between galaxies, and about the remarkable new evidence regarding dark energy and the cosmic expansion-this book gives us a firm foundation for exploring the more speculative fringes of our current understanding. This is a heavily revised and completely updated version of Hodge's Galaxies, which won an Association of American Publishers PROSE Award for Best Science Book of the Year in 1986.

This book gives an accessible account of the history of the Universe; not only what happened, but why it happened. An author of textbooks on the early Universe and inflation, David Lyth now explains both cosmology and the underlying physics to the general reader. The book includes a detailed account of the almost imperceptible structure in the early Universe, and its probable origin as a quantum fluctuation during an early epoch known as the epoch of inflation. It also explains how that early structure is visible now in the cosmic microwave radiation which is our main source of information about the early Universe, and how it gave rise to galaxies and stars. The main text of the book assumes no knowledge of mathematics or physics so that it is accessible to everybody, while an appendix contains more advanced material. As a result the book will be useful for a wide spectrum of readers, including high-school students, undergraduates, postgraduates and professional physicists working in areas other than cosmology. It will also serve as "additional reading" for university courses in general astronomy, astrophysics or cosmology itself.

This book gathers the lecture notes of the 100th Les Houches Summer School, which was held in July 2013. These lectures represent a comprehensive pedagogical survey of the frontier of theoretical and observational cosmology just after the release of the first cosmological results of the Planck mission. The Cosmic Microwave Background is discussed as a possible window on the still unknown laws of physics at very high energy and as a backlight for studying the late-time Universe. Other lectures highlight connections of fundamental physics with other areas of cosmology and astrophysics, the successes and fundamental puzzles of the inflationary paradigm of cosmic beginning, the themes of dark energy and dark matter, and the theoretical developments and observational probes that will shed light on these cosmic conundrums in the years to come.

Rhodri Evans tells the story of what we know about the universe, from Jacobus Kapteyn's Island universe at the turn of the 20th Century, and the discovery by Hubble that the nebulae were external to our own galaxy, through Gamow's early work on the cosmic microwave background (CMB) and its subsequent discovery by Penzias and Wilson, to modern day satellite-lead CMB research. Research results from the ground-based experiments DASI, BOOMERANG, and satellite missions COBE, WMAP and Planck are explained and interpreted to show how our current picture of the universe was arrived at, and the author looks at the future of CMB research and what we still need to learn. This account is enlivened by Dr Rhodri Evans' personal connections to the characters and places in the story.

This book journeys into one of the most fascinating intellectual adventures of recent decades - understanding and exploring the final fate of massive collapsing stars in the universe. The issue is of great interest in fundamental physics and cosmology today, from both the perspective of gravitation theory and of modern astrophysical observations. This is a revolution in the making and may be intimately connected to our search for a unified understanding of the basic forces of nature, namely gravity that governs the cosmological universe, and the microscopic forces that include quantum phenomena. According to the general theory of relativity, a massive star that collapses catastrophically under its own gravity when it runs out of its internal nuclear fuel must give rise to a space-time singularity. Such singularities are regions in the universe where all physical quantities take their extreme values and become arbitrarily large. The singularities may be covered within a black hole, or visible to faraway observers in the universe. Thus, the final fate of a collapsing massive star is either a black hole or a visible naked singularity. We discuss here recent results and developments on the gravitational collapse of massive stars and possible observational implications when naked singularities happen in the universe. Large collapsing massive stars and the resulting space-time singularities may even provide a laboratory in the cosmos where one could test the unification possibilities of basic forces of nature.

How did our modern picture of the universe come into being? Masters of the Universe tells this fascinating story in an unusual format that blends factual and fictional elements. It is based on a series of interviews that a fictional person conducted with leading astronomers and physicists between 1913 and 1965. Among the interviewed scientists are giants such as Albert Einstein, Edwin Hubble, and George Gamow, but also scientists who are less well known today or not primarily known as cosmologists such as Karl Schwarzschild, Paul Dirac, and Svante Arrhenius. By following the interviews the reader gets a lively and "almost authentic" impression of the problems that faced this early generation of cosmologists. Although the interviews are purely fictional, a product of the author's imagination, they could have taken place in just the way that is described. They are solidly based on historical facts and, moreover, supplemented with careful annotations and references to the literature. In this way the book bridges the gap between scholarly and popular history of science.

In the final book of his astonishing career, Carl Sagan brilliantly examines the burning questions of our lives, our world, and the universe around us.

These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century? Here, too, is a rare, private glimpse of Sagan’s thoughts about love, death, and God as he struggled with fatal disease.

Ever forward-looking and vibrant with the sparkle of his unquenchable curiosity, Billions & Billions is a testament to one of the great scientific minds of our day.

This open access volume focuses on the cultural background of the pivotal transformations of scientific knowledge in the early modern period. It investigates the rich edition history of Johannes de Sacrobosco's Tractatus de sphaera, by far the most widely disseminated textbook on geocentric cosmology, from the unique standpoint of the many printers, publishers, and booksellers who steered this text from manuscript to print culture, and in doing so transformed it into an established platform of scientific learning. The corpus, constituted of 359 different editions featuring Sacrobosco's treatise on cosmology and astronomy printed between 1472 and 1650, represents the scientific European shared knowledge concerned with the cosmological worldview of the early modern period until far after the publication of Copernicus' De revolutionibus orbium coelestium in 1543. The contributions to this volume show how the academic book trade influenced the process of homogenization of scientific knowledge. They also describe the material infrastructure through which such knowledge was disseminated, and thus define the premises for the foundation of modern scientific communities.

There are 'voids' obscuring all kinds of objects in the cosmos.Voids may be withinan object, or betweenan object and us. "Dark Nebulae, Dark Lanes, and Dust Lanes" looks out into the deep sky at those apparent darkregions in space, which are among the most compelling telescopic destinations for amateur observers.One famous example is Barnard's dark nebulae - those striking dark clouds set against the background of stars in the Milky Way. But there are countless other less well knownexamples.These dark regions are often ignored altogether or commented upon onlybriefly in astronomy books, and it is all too easy to overlook the treasure trove they offer the observer.

"Dark Nebulae, Dark Lanes, and DustLanes" is a great source of practical information for observers.Such voids may be successfully observed using conventional observing methods, but they are often far better seen with technologies such as light-pollution filters, CCD video cameras, and image intensifiers. This book explains the optimal ways to observe each object in detail."

This title is a comprehensive set of visual descriptions of deep-sky objects visible from the northern hemisphere. It is a record of the most extensive and systematic visual survey of the sky ever done in modern times. 3,000 deep-sky objects are listed with short descriptions of the visual appearance in the author's powerful binocular telescope. Objects in the book are organized by position for easy identification of unknown targets. Full indexes by catalog numbers and names allow searches for specific objects.

The prevailing scientific view of the world just doesn't work! Our most precious and accepted scientific principles, built over millennia by luminaries including Einstein, Darwin and Hawking, are all built on one basic idea, that time is a straight line. However, logical contradictions that arise are given ever-more improbable explanations to fill the gaps - string theory, dark matter, parallel universes. It just doesn't add up. But what if time is not a straight line? What if time is a circle with a relatively short repeating cycle? Then everything falls neatly into place. Welcome to Flash Time: a revolutionary new world view Flash Time is a revolutionary new way of looking at the universe and our place in it by seeing time as a cycle rather than a line. As a result, our most persistent scientific inconsistencies are swept away, along with all our biggest scientific assumptions, and a new `Theory of Everything' that really works is presented. A truly mind-bending book that will change how you think about the world around you.

Do you sometimes wonder why the sky at dusk is filled with color, or how the moon controls the tides? Why do stars twinkle and planets don't? Interested in refining your star-gazing techniques? You don't need any special equipment to marvel at the beauty of the universe, and Night Has a Thousand Eyes will place the cosmic within your grasp.

If you want to know why werewolves only come out at night, are curious about twilight, the seasons and their causes, our solar system, light and darkness, weather, stars and latitude, the moon, light pollution, and the planets, this is the book for you. Filled with science and lore, with references to myths, legends, and "high" and popular culture, this "naked-eye" guide -- no telescope required -- demystifies the celestial in accessible, instructive, and entertaining prose. Night Has a Thousand Eyes is the perfect resource for amateur astronomers and meteorologists of all ages -- city, suburban, and country folk alike -- who pause to enjoy sunsets and identify constellations on a starry night. Illustrated throughout with photographs, sky charts, and diagrams.

At this very moment the most ambitious scientific experiment of all time is beginning, and yet its precise aims are little understood by the general public. This book aims to provide an everyman's guide for understanding and following the discoveries that will take place within the next few years at the Large Hadron Collider project at CERN. The reader is invited to share an insider's view of the theory of particle physics, and is equipped to appreciate the scale of the intellectual revolution that is about to take place. The technological innovations required to build the LHC are among the most astonishing aspects of this scientific adventure, and they too are described here as part of the LHC story. The book culminates with an outline of the scientific aims and expectations at the LHC. Does the mysterious Higgs boson exist? Does space hide supersymmetry or extend into extra dimensions? How can colliding protons at the LHC unlock the secrets of the origin of our universe? These questions are all framed and then addressed by an expert in the field. While making no compromises in accuracy, this highly technical material is presented in a friendly, accessible style. The book's aim is not just to inform, but to give the reader the physicist's sense of awe and excitement, as we stand on the brink of a new era in understanding the world in which we all live.

The aim of the State of the Universe annuals is to provide an annual astronomy review suitable for the popular science level reader to be published every September in a format that will be suitable for, and appeal to, the Christmas market. The book will cover all major astronomical news on topics beyond the Solar System and place them in the context of the longer term goals of astronomers and astrophysicists around the world. The aim is to capture the excitement and vibrancy of modern astronomical research. This section also includes web links for all major news stories, providing a bridge between the public news stories and the actual research web sites.

Chapter 1 a" a ~A Year in News and Picturesa (TM), written by Martin Ratcliffe, appears every year and makes up the first half of the annual. It will present brief summaries of the major announcements, discoveries and news items from that year, with the major ones being explained in detail through later chapters written by invited contributors who are at the forefront of research in these fields. The January meeting of the American Astronomical Society each year will be the major source of astronomical news for the following yeara (TM)s volume, giving access to potential authors and contacts with public information officers of major observatories, space centers, etc.

The invited contributions which make up the second half of the annual each year will cover a variety of topics and are written to appeal to a wide readership. These are written by leading astronomers or science writers. One feature introduced in the first volume, the overall review of the State of the Universe by Dr Jim Kaler will be retained for State ofthe Universe 2008. The set of appendices at the end of the book will include a list of launches of major astronomical observatories/satellites during the past year; a list of planned future astronomical satellites; basic data on all astronomical observatories currently in operation with web links for the reader who wishes to find out more.

This is a reference source for professional and student astrologers alike. The book has been published annually since 1821. It gives the longitudes of all the planets for each day and their latitudes and declinations for every other day, and includes tables of houses for London, Liverpool and New York. The book also contains complete lunar and planetary aspectarians together with all the neccessary data for casting horoscopes for all places in the world, both north and south of the Equator.

Modern physics has revealed a universe that is a much stranger place than we could have imagined, filled with black holes and dark matter and parallel lines meeting in space. And the puzzle at the center of our present understanding of the universe is time.
Now, in The Labyrinth of Time, Michael Lockwood takes the reader on a fascinating journey into the nature of things. A brilliant writer, Lockwood illuminates the philosophical questions about past, present, and future, our experience of time, and the possibility of time travel, in a book that is both challenging and great fun. Indeed, he provides the most careful, lively, and up-to-date introduction to the physics of time and the structure of the universe to be found anywhere in print. He guides us step by step through relativity theory and quantum physics, introducing and explaining the ground-breaking ideas of Newton and Boltzmann, Einstein and Schroedinger, Penrose and Hawking. We zoom in on the behavior of molecules and atoms, and pull back to survey the expansion of the universe. We learn about entropy and gravity, black holes and wormholes, about how it all began and where we are all headed.
Lockwood's aim is not just to boggle the mind but to lead us towards an understanding of the science and philosophy. Things will never seem the same again after a voyage through The Labyrinth of Time.
A model of balance and clarity.
--Paul Davies, Times Higher Education Supplement

Is the universe infinite, or does it have an edge beyond which there is, quite literally, nothing? Do we live in the only possible universe? Why does it have one time and three space dimensions - or does it? What is it made of? What does it mean when we hear that a new particle has been discovered? Will quantum mechanics eventually break down and give way to a totally new description of the world, one whose features we cannot even begin to imagine?
This book aims to give the non-specialist reader a general overview of what physicists think they do and do not know in some representative frontier areas of contemporary physics. After sketching out the historical background, A. J. Leggett goes on to discuss the current situation and some of the open problems of cosmology, high-energy physics, and condensed-matter physics. Unlike most other accounts, this book focuses not so much on recent achievements as on the fundamental problems at the heart of the subject, and emphasizes the provisional nature of our present understanding of things.
