Astrophysics is often -with some justification - regarded as incomprehensible without the use of higher mathematics. Consequently, many amateur astronomers miss out on some of the most fascinating aspects of the subject. Astrophysics Is Easy! cuts through the difficult mathematics and explains the basics of astrophysics in accessible terms. Using nothing more than plain arithmetic and simple examples, the workings of the universe are outlined in a straightforward yet detailed and easy-to-grasp manner. The original edition of the book was written over eight years ago, and in that time, advances in observational astronomy have led to new and significant changes to the theories of astrophysics. The new theories will be reflected in both the new and expanded chapters. A unique aspect of this book is that, for each topic under discussion, an observing list is included so that observers can actually see for themselves the concepts presented -stars of the spectral sequence, nebulae, galaxies, even black holes. The observing list has been revised and brought up-to-date in the Second Edition. Observing the Sun is for amateur astronomers at all three levels: beginning, intermediate, and advanced.The beginning observer is often trying to find a niche or define a specific interest in his hobby, and the content of this book will spark that interest in solar observing because of the focus on the dynamics of the Sun.Intermediate and advanced observers will find the book invaluable in identifying features (through photos, charts, diagrams) in a logical, orderly fashion and then guiding the observer to interpret the observations.Because the Sun is a dynamic celestial body in constant flux, astronomers rarely know for certain what awaits them at the eyepiece. All features of the Sun are transient and sometimes rather fleeting. Given the number of features and the complex life cycles of some, it can be a challenging hobby. Observing the Sun provides essential illustrations, charts, and diagrams that depict the forms and life cycles of the numerous features visible on the Sun. 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. If you’ve ever been interested in the night sky and the wonders above our heads, search no further: your ultimate resource for all things in the universe is here. From David Dickinson and Fraser Cain, publisher of the widely popular astronomy news site, Universe Today, comes the complete guide of the night sky, ranging from the best tips and tricks for viewing, an overview of the solar system and our galaxy to exclusive interviews with top NASA scientists, interwoven with exclusive, beautiful photography from top night sky photographers.Foreword is expected to be written by a top industry professional (hopefully Dr. Pamela Gay or Bill Nye). With calendars, charts and graphs, you’ll treasure this definitive resource for many night sky viewings from now and for years to come. Any amateur astronomer who is interested in astrophotography, particularly if just getting started, needs to know what objects are best for imaging in each month of the year. These are not necessarily the same objects that are the most spectacular or intriguing visually. The camera reveals different things and has different requirements. What objects in the sky tonight are large enough, bright enough, and high enough to be photographed? This book reveals, for each month of the year, the choicest celestial treasures within the reach of a commercial CCD camera. Helpful hints and advice on framing, exposures, and filters are included. Each deep sky object is explained in beautiful detail, so that observers will gain a richer understanding of these astronomical objects.This is not a book that dwells on the technology of CCD, Webcam, wet, or other types of astrophotography. Neither is it a book about in-depth computer processing of the images (although this topic is included). Detailed discussions of these topics can be found in other publications. This book focuses on what northern latitude objects to image at any given time of the year to get the most spectacular results. David Dickinson, co-author of The Universe Today Guide to Viewing the Cosmos, has created the ultimate field guide for backyard astronomers. Whether you want to impress viewers at a star party, or learn what you can see with your new telescope, David shows you how to find the most impressive the night sky has to offer.Backyard astronomy has become more accessible through apps and technology, but they tend to be inaccurate and a source of frustration when trying to find objects with your telescope. With 44 sky charts and David’s expertise, it’s like having a pro-astronomer out in the field with you.Broken down by month and by hemisphere to ensure you get the best possible view, David shows you how to find objects like spiral galaxies, the 14th brightest star in the sky, and other stars that bring the “wow factor” to astronomy. This book describes the many astronomical and human-scale issues that make interstellar travel a formidable challenge, even with the right technology for making the actual trip. Since the 1920\'s, science fiction authors have invented dozens of ways to make interstellar travel a reality. Sadly, after nearly 100 years of effort, scientists and engineers have yet to invent a single inexpensive technology to get us to the stars. What is more disturbing about this challenge is that the actual technology to make the trip is mostly irrelevant. Some of the issues are already known and being addressed such as: What will be our destination? How many travelers should go? What will happen to human health along the way? But the Big Picture of interstellar travel goes well beyond the design of the engines that power our starships. Once we arrive at our destination, what will we do? Will our immune systems be so compromised from the travel that we can never actually visit the surface of a biologically-active planet? What will we breath? Will we be forced to live \'under a dome\' and never venture outside without a spacesuit? What kind of a reward will that be for a decades or centuries-long voyage? What will communication with Earth be like with time delays of 100 years? These and many other questions will be covered as astronomer Sten Odenwald explores the other issues and challenges of interstellar travel that arise from living in an unfortunately very limited physical world. He will also explore optimistic scenarios involving artificial intelligence and hibernation that could completely change the game in making interstellar travel a reality.
