With over 150,000 copies sold since its first publication, this is one of the most popular astronomy books of all time. This unique guidebook to the night sky shows you how to observe a host of celestial wonders. Its distinct format of object-by-object spreads illustrates how deep-sky objects and planets actually look through a small telescope, while its large pages and spiral binding allow for use outside. Along with updated star names and astronomical information, this new edition provides links to a dedicated webpage with up-to-date tables and images, and an improved planets chapter. The many Dobsonian-friendly images and small telescope views have been revised to account for changes in modern telescope technology, such as larger field of view eyepieces. With dedicated chapters on Northern and Southern Hemisphere objects, it's never been easier to explore the night sky, wherever you are.

The introduction of the moving sphere as a model for understanding the celestial phenomena caused a great breakthrough in scientific thinking about the structure of the world. It provided the momentum for making celestial globes and mapping the stars. Celestial globes were produced first by Greek astronomers, and soon became greatly appreciated in antiquity as decorative objects (3 antique globes). The design and construction of the globe varied greatly as it passed through the Arabic (10 scientific globes made before 1500) and Medieval European cultures (3 scientific globes made before 1500). It was the starting-point for the design of many maps in antiquity and later in the Middle Ages (33) serving to illustrate books such as Aratus's Phaenomena. In the early fifteenth century scientific celestial maps (5) were constructed in their own right, independent of globes. In this book all extant celestial maps and globes made before 1500 are described and analysed in detail. This prestigious study will appeal to academic historians of science and astronomy, and art historians alike.

Designed with the beginner in mind and useful to anyone interested in astronomy. Star Maps for Beginners is the classic guide to viewing and understanding the heavens. Its superb maps -- drawn in the shape of two crossed ellipses -- provide the reader with a unique perspective on the sky and have been widely acknowledged as the easiest system yet devised for locating any constellation at any time of the year.

Now revised for the 1990s, with updated planet charts and a new section on spotting meteor showers. Star Maps for Beginners includes:

12 complete maps -- one for each month -- showing the positions of the constellations viewed from every direction
a synoptic table that shows how to choose the proper map for use at any time special tables that give approximate positions of the planets for the years 1992 through 1997
the most up-to-date overview of the solar system available today the latest facts about each of the planets -- orbit, size, atmosphere, internal structure, climate, and terrain
a full chapter on the history and development of the constellations, and the ancient legends and mythological lore surrounding them
a special section on meteors -- how they originate and when and where to spot them.

Initially published in 1942 and now celebrating its 50th anniversary, Star Maps for Beginners has sold more than 450,000 copies.

The Moon is not just a static piece of cosmic matter in our night sky, but a dynamic living being. Throughout her journey around the Earth which takes about 29.5 days she shows us her different faces, growing from a silver sliver in the sky to an awe-inspiring illuminated sphere, before returning to darkness again. She changes colour and moves through a variety of star constellations reflecting the energies at play each day. The Moon gives us a map to a cyclical way of living; the blueprint for a life that breathes in harmony with the rhythm of the natural world around us. She teaches us about the importance of embracing quiet and reflective times as much as celebrating the times we experience life in its fullest expression. She informs us when to plant the seeds of our dreams and when to take stock and harvest what we have been growing. What will you discover about yourself when you tune into the moon?

Amateur astronomers of all expertise from beginner to experienced will find this a thorough star cluster atlas perfect for easy use at the telescope or through binoculars. It enables practical observers to locate the approximate positions of objects in the sky, organized by constellation. This book was specifically designed as an atlas and written for easy use in field conditions. The maps are in black-and-white so that they can be read by the light of a red LED observer's reading light. The clusters and their names/numbers are printed in bold black, against a "grayed-out" background of stars and constellation figures. To be used as a self-contained reference, the book provides the reader with detailed and up-to-date coverage of objects visible with small-, medium-, and large-aperture telescopes, and is equally useful for simple and computer-controlled telescopes. In practice, GO-TO telescopes can usually locate clusters accurately enough to be seen in a low-magnification eyepiece, but this of course first requires that the observer knows what is visible in the sky at a given time and from a given location, so as to input a locatable object. This is where "The Observer's Guide to Star Clusters" steps in as an essential aid to finding star clusters to observe and an essential piece of equipment for all amateur astronomers.

As interest in astrology continues to grow, so too have the sales of this accurate working tool. Raphael's Ephemeris continues to fill the astrologer's everyday need for pocket reference and is used extensively by professionals and students alike. The Ephemeris is widely recognised in its classic livery and should be displayed by general bookshops, specialised New Age shops and, of course, in every astrology outlet. Longitudes of all the planets for every day of the year. Tables of Houses for London, Liverpool and New York. Complete Lunar and Planetary Aspectarian together with all the necessary data for casting horoscopes North and South of the Equator.

Raphael's Astronomical Ephemeris has been published every year for well over 100 years. Renowned for its accuracy, it is respected the world over as the number one portable planetary guide and aspectarian.

Modern telescopes of even modest aperture can show thousands of double stars. Many are faint and unremarkable but hundreds are worth searching out. Veteran double-star observer Bob Argyle and his co-authors take a close-up look at their selection of 175 of the night sky's most interesting double and multiple stars. The history of each system is laid out from the original discovery to what we know at the present time about the stars. Wide-field finder charts are presented for each system along with plots of the apparent orbits and predicted future positions for the orbital systems. Recent measurements of each system are included which will help you to decide whether they can be seen in your telescope, as well as giving advice on the aperture needed. Double star observers of all levels of experience will treasure the level of detail in this guide to these jewels of the night sky.

Are we alone in the universe? If not, where is everybody? An engaging exploration of one of the most important unsolved problems in science. Everything we know about how planets form and how life arises suggests that human civilization on Earth should not be unique. We ought to see abundant evidence of extraterrestrial activity-but we don't. Where is everybody? In this volume in the MIT Press Essential Knowledge series, science and technology writer Wade Roush examines one of the great unsolved problems in science: is there life, intelligent or otherwise, on other planets? This paradox (they're bound to be out there; but where are they?), first formulated by the famed physicist Enrico Fermi, has fueled decades of debate, speculation, and, lately, some actual science. Roush lays out the problem in its historical and modern-day context and summarizes the latest thinking among astronomers and astrobiologists. He describes the long history of speculation about aliens (we've been debating the idea for thousands of years); the emergence of SETI (the Search for Extraterrestrial Intelligence) as a scientific discipline in the 1960s, and scientists' use of radio and optical techniques to scan for signals; and developments in astrobiology (the study of how life might arise in non-Earth like environments) and exoplanet research (the discovery of planets outside our solar system). Finally, he discusses possible solutions to the Fermi Paradox and suggests way to refocus SETI work that might increase the chances of resolving the paradox-and finding extraterrestrials.
