Cosmology is the study of the origin, size, and evolution of the entire universe. Every culture has developed a cosmology, whether it be based on religious, philosophical, or scientific principles. In this book, the evolution of the scientific understanding of the Universe in Western tradition is traced from the early Greek philosophers to the most modern 21st century view. After a brief introduction to the concept of the scientific method, the first part of the book describes the way in which detailed observations of the Universe, first with the naked eye and later with increasingly complex modern instruments, ultimately led to the development of the "Big Bang" theory. The second part of the book traces the evolution of the Big Bang including the very recent observation that the expansion of the Universe is itself accelerating with time.

On March 21, 2013, the European Space Agency released a map of the afterglow of the Big Bang. Taking in 440 sextillion kilometres of space and 13.8 billion years of time, it is physically impossible to make a better map: we will never see the early universe in more detail. On the one hand, such a view is the apotheosis of modern cosmology, on the other, it threatens to undermine almost everything we hold cosmologically sacrosanct. The map contains anomalies that challenge our understanding of the universe. It will force us to revisit what is known and what is unknown, to construct a new model of our universe. This is the first book to address what will be an epoch-defining scientific paradigm shift. Stuart Clark will ask if Newton's famous laws of gravity need to be rewritten; if dark matter and dark energy are just celestial phantoms? Can we ever know what happened before the Big Bang? What's at the bottom of a black hole? Are there universes beyond our own? Does time exist? Are the once immutable laws of physics changing?

From the age of ten, looking up at the stars, Jerry Ross knew that he wanted to journey into space. This autobiography tells the story of how he came not only to achieve that goal, but to become the most-launched astronaut in history, as well as a NASA veteran whose career spanned the entire US Space Shuttle program. From his childhood in rural Indiana, through education at Purdue University, and a career in the US Air Force, Ross charted a path to NASA after overcoming many setbacks-from failing to qualify for Air Force pilot training because of "bad" eyesight, to an initial failure to be selected into the astronaut program. The majority of the book is an insider's account of the US Space Shuttle program, including the unforgettable experience of launch, the delights of weightless living, and the challenges of constructing the International Space Station. Ross is a uniquely qualified narrator. During seven spaceflights, he spent 1,393 hours in space, including 58 hours and 18 minutes on nine space walks. Life on the ground is also described, including the devastating experiences of the Challenger and Columbia disasters. For readers who have followed the space program from Mercury through the International Space Station and wonder what comes next, this book provides fascination; for young people interested in space exploration and reaching for their dreams, whatever they might be, this book provides inspiration. Full of stories of spaceflight that few humans have ever experienced, told with humor and honesty, Spacewalker presents a unique perspective on the hard work, determination, and faith necessary to travel beyond this world. Key Points: An insider's account of the US Space Shuttle program, from before its first launch through the final landing, and the building of the International Space Station. A firsthand account of life in space from the first human to fly seven missions. An inspirational story of a personal journey from rural Indiana to outer space, powered by a deep Christian faith.

What does it take to consider a planet potentially habitable? If a planet is suitable for life, could life be present? Is life on other planets inevitable? Searching for Habitable Worlds answers these questions and provides both the general public and astronomy enthusiasts with a richly illustrated discussion of the most current knowledge regarding the search for extrasolar planets. Nearly everyone wants to know if we are alone in the universe. This book might not have the answers, but shows where we should look. This book is a fun and accessible book for everyone from middle schoolers to amateur astronomers of all ages. The use of non-technical language and abundant illustrations make this a quick read to inform everyone about the latest movement in the search for other planets that we might be able to inhabit. After a brief discussion on why humans are hard-wired to be curious, and to explore the unknown, the book describes what extrasolar planets are, how to detect them, and how to pin down potential targets. In addition, a data-driven list of the best candidates for habitability is profiled and the next generation of exoplanet-hunting scientific instruments and probes are identified.

The study of dark matter, in both astrophysics and particle physics, has emerged as one of the most active and exciting topics of research in recent years. This book reviews the history behind the discovery of missing mass (or unseen mass) in the Universe, and ties this into the proposed extensions to the Standard Model of Particle Physics (such as Supersymmetry), which were being proposed within the same time frame. This book is written as an introduction to these problems at the forefront of astrophysics and particle physics, with the goal of conveying the physics of dark matter to beginning undergraduate majors in scientific fields. The book goes onto describe existing and upcoming experiments and techniques, which will be used to detect dark matter either directly on indirectly.

Visual Astronomy introduces the basics of observational astronomy, a fundamentally limitless opportunity to learn about the universe with your unaided eyes or with tools such as binoculars, telescopes, or cameras. The book explains the essentials of time and coordinate systems and their use in basic observations of the night sky. Readers will learn how to use widely accessible resources to determine what is visible (and when it is visible) from their particular location. Distinct attention is paid to the dependence of the appearance and motion on the observer's location, by extending the discussion to include various latitudes in both the Northern and Southern Hemispheres. This approach provides a better understanding of the night sky and makes the material more interesting and relevant around the world, not just in North America. You don't need any mathematical skill or technical knowledge to quickly grasp the concepts of basic astronomy, nor do you need expensive equipment to look up at the night sky and understand what you see. If you do have or can access a telescope, Visual Astronomy will teach you the fundamentals of its use and how to get the best views possible. Links to major telescope facilities around the world; current and past space missions; links to free sky simulation applications; and ideas for observation projects make this an excellent learning tool for the new hobbyist or for teachers who wish to show their students why visual astronomy is a lifetime love for millions.

Adaptive optics (AO) corrects distortions created by atmospheric turbulence and delivers diffraction-limited images on ground-based telescopes. The vastly improved spatial resolution and sensitivity has been utilized for studying everything from the magnetic fields of sunspots upto the internal dynamics of high-redshift galaxies. This thesis about AO science from small and large telescopes is divided into two parts: Robo-AO and magnetar kinematics. In the first part, I discuss the construction and performance of the world's first fully autonomous visible light AO system, Robo-AO, at the Palomar 60-inch telescope. Robo-AO operates extremely efficiently with an overhead

Taking inspiration from Siv Cedering's poem in the form of a fictional letter from Caroline Herschel that refers to "my long, lost sisters, forgotten in the books that record our science", this book tells the lives of twenty-five female scientists, with specific attention to astronomers and mathematicians. Each of the presented biographies is organized as a kind of "personal file" which sets the biographee's life in its historical context, documents her main works, highlights some curious facts, and records citations about her. The selected figures are among the most representative of this neglected world, including such luminaries as Hypatia of Alexandra, Hildegard of Bingen, Elisabetha Hevelius, and Maria Gaetana Agnesi. They span a period of about 4000 years, from En HeduAnna, the Akkadian princess, who was one of the first recognized female astronomers, to the dawn of the era of modern astronomy with Caroline Herschel and Mary Somerville. The book will be of interest to all who wish to learn more about the women from antiquity to the nineteenth century who played such key roles in the history of astronomy and science despite living and working in largely male-dominated worlds.
