It was on ce said that 'the night sky always looks much the same'. In fact, nothing could be further from the truth. There are 365 days in each year (366 in a Leap Year!), and from an astronomical point of view no two are alike. What I aim to do, in this book, is to go through a complete year and point out some special items of interest for each night. It may be a double star, a vari able star or a nebula; it may be a planet, or even the Moon in some particular aspect - there is plenty of variety. (Anyone unfamiliar with astronomical terms should consult the Glossary at the end ofthis book. ) Let it be said at once that you do not need a large and expensive telescope. A surprising amount can be seen with the naked eye, and binoculars give increased range; indeed, it is probably fair to say that good binoc ulars are ideal for the beginner, and are far better than very small telescopes. Telescopes are of two types: refractors, and reflectors. A refractor collects its light by means of a glass lens known as an object-glass (OG); the light passes down the telescope tube and is brought to focus, where an image is formed and is then magnified by a second lens, termed an eyepiece.
Discusses how to select and use binoculars and telescopes, how to observe planets, meteors, comets, and other celestial bodies, and how to use star charts.
One of the wonders of the universe we live in is the Milky Way. It spans the entire sky and can be seen every night of the year from anywhere on Earth. This is the first book that deals specifically with what can be seen within the Milky Way from a practical observer's point of view. Astronomy of the Milky Way covers every constellation that the Milky Way passes through, and describes in detail the many objects that can be found therein, including stars, double and multiple stars, emission nebulae, planetary nebulae, dark nebulae and supernovae remnants, open and galactic clusters, and galaxies. It also describes the one thing that is often left out of observing guides - the amazing star clouds of the Milky Way itself. It is one of a two-volume set that deal with the entire Milky Way - this second volume looks at what can be seen predominantly from the Southern skies In addition to the descriptive text there are many star charts and maps, as well as the latest up-to-date images made by observatories around the world and in space, as well as images taken by amateur astronomers. Equipped with this book, an amateur astronomer can go out on any clear night of the year and observe the galaxy we live in - The Milky Way.
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.
To the naked eye, the most evident defining feature of the planets is their motion across the night sky. It was this motion that allowed ancient civilizations to single them out as different from fixed stars. “The Observer’s Guide to Planetary Motion” takes each planet and its moons (if it has them) in turn and describes how the geometry of the Solar System gives rise to its observed motions. Although the motions of the planets may be described as simple elliptical orbits around the Sun, we have to observe them from a particular vantage point: the Earth, which spins daily on its axis and circles around the Sun each year. The motions of the planets as observed relative to this spinning observatory take on more complicated patterns. Periodically, objects become prominent in the night sky for a few weeks or months, while at other times they pass too close to the Sun to be observed. “The Observer’s Guide to Planetary Motion” provides accurate tables of the best time for observing each planet, together with other notable events in their orbits, helping amateur astronomers plan when and what to observe. Uniquely each of the chapters includes extensive explanatory text, relating the events listed to the physical geometry of the Solar System. Along the way, many questions are answered: Why does Mars take over two years between apparitions (the times when it is visible from Earth) in the night sky, while Uranus and Neptune take almost exactly a year? Why do planets appear higher in the night sky when they’re visible in the winter months? Why do Saturn’s rings appear to open and close every 15 years? This book places seemingly disparate astronomical events into an understandable three-dimensional structure, enabling an appreciation that, for example, very good apparitions of Mars come around roughly every 15 years and that those in 2018 and 2035 will be nearly as good as that seen in 2003. Events are listed for the time period 2010-2030 and in the case of rarer events (such as eclipses and apparitions of Mars) even longer time periods are covered. A short closing chapter describes the seasonal appearance of deep sky objects, which follow an annual cycle as a result of Earth’s orbital motion around the Sun.
