How did it all begin? Where is it all going? A little over a century ago, a young Albert Einstein presented his general theory of relativity to the world and utterly transformed our understanding of the universe. His theory changed the way we think about space and time, revealed how our universe has been expanding from a hot dense state called the big bang and predicted black holes. WHERE THE UNIVERSE CAME FROM is a 13.8-billiion-year journey through the cosmos. Discover how Einstein's work explains why the cosmos is the way it is, why 95% of the universe is missing, how physicists go to extraordinary lengths to unlock gravity's secrets and how black holes could hold the key to a theory of everything. ABOUT THE SERIES New Scientist Instant Expert books are definitive and accessible entry points to the most important subjects in science; subjects that challenge, attract debate, invite controversy and engage the most enquiring minds. Designed for curious readers who want to know how things work and why, the Instant Expert series explores the topics that really matter and their impact on individuals, society, and the planet, translating the scientific complexities around us into language that's open to everyone, and putting new ideas and discoveries into perspective and context.

Alien Skies: A Travelogue of the Universe gives readers the opportunity to travel through the universe, visiting a series of celestial destinations carefully chosen to span the extraordinary limits of space and time that bound our amazing cosmos. The destinations in Alien Skies reveal the unusual skies seen from throughout the solar system, nearby stars, nebulae, and star clusters, and during a series of voyages exploring the structure and content of our home galaxy. The itinerary includes nearby 'normal' galaxies, exotic active galaxies, as well as galaxy groups, clusters and cosmic voids. The final destinations of the journey traverse space and time to view the evolution of galaxies and cosmic structure, and of the universe as a whole. Alien Skies provides a broad, factual overview of modern astronomy, while instilling interest and enthusiasm of how science reveals the wonders of our universe. This book can serve as the text for introductory courses aimed at non-science majors or as background for courses geared to astronomy and astrophysics majors. It is also suitable for advanced courses at the high school level.

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.

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.
