Stephen James O'Meara - Böcker

Month by month, star by star, object by object, Stephen James O'Meara takes readers on a celestial journey to many of the most prominent stars and constellations visible from mid-northern latitudes. Filled with interesting anecdotes about the stars and constellations and their intriguing histories, this book is both a useful guide for amateur astronomers, and a great first-time reference for those just starting out. After describing a constellation's mythology, readers are guided in locating and identifying its brightest stars in the sky, as well as any other bright targets of interest - colourful stars, double or multiple stars, star clusters and asterisms, nebulae, galaxies, variable stars, and more. This book will help beginning stargazers become familiar with the stars and constellations visible from their backyards, and explore the brightest and best stars, nebulae, and clusters visible through inexpensive, handheld binoculars.

The bright galaxies, star clusters, and nebulae catalogued in the late 1700s by the famous comet hunter Charles Messier are still the most widely observed celestial wonders in the sky. The second edition of Stephen James O'Meara's acclaimed observing guide to the Messier Objects features improved star charts for helping you find the objects, a much more robust telling of the history behind their discovery - including a glimpse into Messier's fascinating life - and updated astrophysical facts to put it all into context. These additions, along with new photos taken with the most advanced amateur telescopes, bring O'Meara's first edition more than a decade into the twenty-first century. Expand your universe and test your viewing skills with this truly modern Messier guide. It is a must for all budding night watchers.

The Caldwell Catalogue, compiled by the late Sir Patrick Moore (1923-2012), has delighted amateur astronomers worldwide since its publication in 1995. Twenty years on, Stephen James O'Meara revisits his guide to these 109 deep-sky delights, breathing new life into them and the 20 additional observing targets included as an appendix. This second edition retains O'Meara's detailed visual descriptions and sketches, accompanied by stunning new images taken by amateur photographer Mario Motta and observations by Magda Streicher. The astrophysical descriptions have been updated to account for the many advances in our understanding of the objects, not least due to an armada of space-borne observatories and the new technologies used in large ground-based telescopes. Ideal for observers who have completed the Messier objects and are looking for their next challenge, Deep-Sky Companions: The Caldwell Objects is a fitting tribute from a renowned visual observer to one of astronomy's most famous personalities.

No other planet has so fired the human imagination as Mars. The possibility of life on the planet was an obsession in the 19th century. It is not surprising to find that it has become so once again, because of all the planets in the solar system (apart from Earth), Mars has always been regarded as the most likely to serve as the abode of life. Now that there are hints that the planet may have held "liquid water" (a prerequisite for life, in contrast to the frozen water of the ice caps) much more recently than anyone had supposed, excitement over Mars exploration has never been higher.In this engaging, eloquent account of our love affair with the Red Planet, William Sheehan and Stephen James O'Meara review the history of human fascination with our neighbor in the solar system, and look at the prospects for manned spaceflight to Mars in this new century. The authors portray the history of Mars investigations through the eyes of the dreamers and achievers that have made the planet such an integral part of the human psyche. They reveal the discoverers' hardships, their strength in the face of criticisms, and the glories of their successes.What Everest and the moon were to the 20th century, Mars will be to the 21st. Mars is our Everest, a new frontier that will continue to spur the greatest flights of imagination and the most astounding technical feats. Projects are already underway to make these dreams a reality. This book will prepare you and fill you with enthusiasm for the adventure ahead.
