The New American Ephemeris for the 21st Century 2000-2100 at Midnight, Michelsen Memorial Edition Compiled and Programmed by Rique Pottenger, based on the earlier work of Neil F Michelsen Memorial text and Introduction compiled and written by Maria Kay Simms In 1976, Neil F Michelsen (1931-1990) compiled, programmed and published the first edition of The American Ephemeris that set new standards of accuracy for contemporary astrology. In 2006, celebrating the 30th anniversary of first publication of the first volume of work that grew to become Michelsen's comprehensive American Ephemeris series, Rique Pottenger continued the work that Neil began. Within The New American Ephemeris for the 21st Century 2000-2100 at Midnight is the familiar data and format long used and trusted by astrologers worldwide, now updated and expanded, with new features. This ephemeris is unique among others in the series for its memorial text section that documents, partially from excerpts from Michelsen's own writing, and partially from testimonials of colleagues, a history of the development of computer technology for astrology. Features of this entire 21st century edition include improvements in the computer generating program that enable finding double ingresses in a single day plus more accurate station times. Ceres, the asteroid that was elevated to planetary status by the IAU (International Astronomical Union) in 2006, has been added to the daily longitude listings in her position between Mars and Jupiter. The new planet Eris, whose discovery precipitated the IAU decisions of 2006, moves, at most, about 3 minutes per month, so her position is listed once per month in the Astro Data box, along with monthly positions for Chiron, Pallas, Juno and Vesta. A new formula increases the accuracy of monthly positions of the Galactic Center. Phenomena listed in the Astro Data column are sorted by time as well as by date. Also, the planetary ingress data includes R if the planet is retrograde when it ingresses.

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.

Marvel at the wonders of the Universe, from stars and planets to black holes and nebulae, in this exploration of our Solar System and beyond. Universe opens with a look at astronomy and the history of the Universe, using 3D artworks to provide a comprehensive grounding in the fundamental concepts of astronomy, including the basic techniques of practical astronomy. The core of the book is a tour of the cosmos covering the Solar System, the Milky Way, and galaxies beyond our own. Explanatory pages introduce different celestial phenomena, such as galaxies, and are followed by catalogues that profile the most interesting and important examples. A comprehensive star atlas completes the picture, with entries on each of the 88 constellations and a monthly sky guide showing the night sky as it appears throughout the year as viewed from both the northern and southern hemispheres.

Cometography is the most complete and comprehensive collection of data on comets available. It comes in four self-contained sequential volumes and this, the first, covers ancient times through to the end of the eighteenth century. Cometography uses the most reliable orbits known to determine all the key parameters of each well observed comet. Cometography also provides nontechnical details to help the reader understand how the comet may have influenced various cultures at the time of its appearance. All the information in Cometography has been sourced directly from the original documents, including European monastic histories, Roman, Greek and Muslim texts, Chinese, Japanese and Korean scripts. In many cases, dates of important historical events can be corrected based on the appearance of a comet and identified using this book. Cometography will be valuable to historians of science as well as providing amateur and professional astronomers with a definitive reference on comets through the ages.

The only small, popular book on the important subject of ancient calendars.
The study of heavenly cycles is common to most ancient cultures. The ancient Egyptians, Chinese, and Babylonians all tried to make sense of the year. But it fell to the later Mesoamerican Maya to create a series of calendars that could be cross referenced. In doing so, the Maya discovered many strange numerical harmonics. Their lunar calendar was extremely accurate--far more so than the Greek Metonic cycle; they tracked Venus to an accuracy of less than a day in five hundred years and their tables could have been used to predict eclipses seven hundred years in the future. This book will provide a much needed compact guide to the Mayan calendar systems as well as covering the essentials of calendar development throughout the world.

The interstellarum Deep Sky Atlas set a new high standard for modern celestial cartography. The same team now presents the interstellarum Deep Sky Guide, its unique observing companion. Taking an intuitive visual approach, for each spread of the Atlas, the Guide focuses on carefully selected objects, either as colored composite POSS plates or through the authors' own eyepiece sketches. They allow you to estimate the visibility of features in the telescope while planning observations. Stars and other objects in the vicinity are highlighted, so they also serve as finder charts at night. An index map on each spread allows you to quickly find each object's location in the Atlas. The interstellarum Deep Sky Guide takes all the hassle out of preparing for observing sessions - there's no need to print star charts or photos. Simply grab your Atlas and your Guide, and go observe!

In The Destinies of the Stars the evolution of the stars and planets are traced through the spiral nebula, the gaseous stars, the sun, the worlds to be, Jupiter and Saturn, the world, to the final destiny of all, the dead planets, Mercury and Mars.

Planetary scientist and educator Ken Coles has teamed up with Ken Tanaka from the United States Geological Survey's Astrogeology team, and Phil Christensen, Principal Investigator of the Mars Odyssey orbiter's THEMIS science team, to produce this all-purpose reference atlas, The Atlas of Mars. Each of the thirty standard charts includes: a full-page color topographic map at 1:10,000,000 scale, a THEMIS daytime infrared map at the same scale with features labeled, a simplified geologic map of the corresponding area, and a section describing prominent features of interest. The Atlas is rounded out with extensive material on Mars' global characteristics, regional geography and geology, a glossary of terms, and an indexed gazetteer of up-to-date Martian feature names and nomenclature. This is an essential guide for a broad readership of academics, students, amateur astronomers, and space enthusiasts, replacing the NASA atlas from the 1970s.

Removes the scanning artefacts and transmission imperfections to produce a most comprehensive and beautifully detailed set of images of the lunar surface.

To help practical astronomers, all the photographs are systematically related to an Earth-based view.

Organized to make it easy for astronomers to use, enabling ground-based images and views to be compared with the Orbiter photographs.

A CD is included, providing the enhanced and cleaned photographs for screen viewing, lectures, etc..

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.
