Of all the fixed stars in the night sky, Sirius is by far the brightest almost twice as bright as its nearest rival, the star Canopus, which lies too far south to be viewed from most of the Northern Hemisphere. Only the Sun, Moon and the planets Venus, Jupiter and, at times, Mars, appear brighter. Sirius, with its flashing brilliance, is a striking feature of the northern winter sky and has understandably drawn the attention of observers of the night sky for thousands of years.

Sirius has many names. Astronomers recognize over fifty designations for the star, but the most...

Amateur astronomers - particularly deep-sky observers - are always on the lookout for new observing challenges. The Herschel Objects, and How to Observe Them offers the exciting opportunity of retracing the steps of the greatest visual observer and celestial explorer that ever lived. This is a practical guide to seeing the most impressive of Herschel's star clusters, nebulae and galaxies.

There has never been - and as of the time of submitting this proposal there still isn't - an observer's book devoted to the Herschel objects. The US-based Astronomical League has for several years...

Reflector antennas are widely used in the microwave and millimeter wavelength domain. Radio astronomers have developed techniques of calibration of large antennas with radio astronomical methods. These have not been comprehensively described. This text aims to fill this gap. It takes a practical approach to the characterisation of antennas. All calculations and results in the form of tables and figures have been made with Mathematica by Wolfram Research. The reader can use the procedures for the implementation of his own input data. The book should be of use to all who are involved in the...

This book contains the latest results on the plasma environment of Mars and its interaction with the solar wind. These results include mapping of the plasma environment with the instruments on Mars Express and Mars Global Surveyor, the latest numerical simulations, and theoretical studies. This comprehensive examination of the Mars environment also sets the stage for the interpretation of the Venus Express measurements.

The aim of the Space Exploration annuals is to provide a yearly update on recent space launches, missions and results, to be published every September in a format that will be suitable for, and appeal to, the Christmas market. The annual will cover space exploration from a variety of angles, looking back at past missions, reviewing those currently under way and detailing those planned for the future, and encompassing both manned and unmanned spaceflight.

Chapter 1 - The Annual Review, written by Brian Harvey appears every year. It will include details of all satellite and...

The aim of the State of the Universe annuals is to provide an annual astronomy review suitable for the popular science level reader to be published every September in a format that will be suitable for, and appeal to, the Christmas market. The book will cover all major astronomical news on topics beyond the Solar System and place them in the context of the longer term goals of astronomers and astrophysicists around the world. The aim is to capture the excitement and vibrancy of modern astronomical research. This section also includes web links for all major news stories, providing a bridge...

For the experienced amateur astronomer who is wondering if there is something useful, valuable, and permanent that can be done with his or her observational skills, the answer is, "Yes, you can " This is the book for the experienced amateur astronomer who is ready to take a new step in his or her astronomical journey. Unfortunately, there is no modern text that points curious amateur astronomers to the research possibilities that are open to them. At the 2006 meeting of the Society for Astronomical Sciences, quite a few participants agreed that the lack of such a text was a serious gap in...

Guide to Observing Deep-Sky Objectsis a reference book for amateur astronomers. It contains, for each constellation, a star chart showing the Bayer labels, a table for many of the stars in the constellation, along with their positions and magnitudes, and a table of the deep-sky objects in the constellation, with relevant observational data. Facing pages provide unique year-long graphs that show when the constellation is visible in the sky, allowing the user to quickly determine whether a given constellation can be seen, and when the best time to see it will be.

Although most people have some knowledge of the essential structure of the Solar System, few are familiar with the large and varied array of objects that travel with and between the planets in their journeys around the Sun.

Imaging techniques from Earth continue to improve, while missions such as Voyager, Galileo and the Hubble Space Telescope have yielded many excellent images. Most significantly of all, several missions in recent years have shown a huge diversity of objects in close-up for the first time. The book will take advantage of the rich pool of images that is available,...

Venus and Mercury have long been regarded as difficult targets for amateur observers, but advances in commercially-made telescopes have brought them within the skills of observers of only moderate experience. Peter Grego's fascinating book presents an up-to-date, detailed description of the history and geology of the so-called inferior planets, and provides the latest, most useful advice on observing and recording them with commercially-available telescopes and cameras. The book also offers a wealth of detailed practical information on every aspect of observing, from safely targeting the...
