According to world-famous astronomer David Levy, an eclipse of the sun “is a natural event with unnatural consequences. In fact, a total eclipse of the Sun has the power to rip through to the core of your being.” Levy should know, having experienced the power of the vanishing Sun first as a child then in 1999 on a ship in the North Atlantic. It was that voyage to the darkness of the disappearing Sun, followed by a rendezvous with a brilliant display of the Northern Lights, that formed the inspiration for this book. Levy recounts the recorded history of eclipses, how they have been perceived by ancient cultures, how they can be predicted, and how best to view them. In addition, he explains the science of solar eclipses and what can be gained by studying them. In a manner accessible to all readers, Levy recounts the story of nature’s most profound displays.

Deep-Sky Companions: The Secret Deep

In this fresh list, Stephen James O'Meara presents 109 new objects for stargazers to observe. The Secret Deep list contains many exceptional objects, including a planetary nebula whose last thermal pulse produced a circumstellar shell similar to the one expected in the final days of our Sun's life; a piece of the only supernova remnant known visible to the unaided eye; the flattest galaxy known; the largest edge-on galaxy in the heavens; the brightest quasar; and the companion star to one of the first black hole candidates ever discovered. Each object is accompanied by beautiful photographs and sketches, original finder charts, visual histories and up-to-date astrophysical information to enrich the observing experience. Featuring galaxies, clusters and nebulae not covered in other Deep-Sky Companions books, this is a wonderful addition to the series and an essential guide for any deep-sky observer.

Deep-Sky Companions: Hidden Treasures

Stephen O'Meara's new and exciting observing guide spotlights an original selection of 109 deep-sky objects that will appeal to sky-watchers worldwide. His 'hidden treasures' include a wonderful assortment of galaxies, open clusters, planetary nebulae and more, all of which have been carefully chosen based on their popularity and ease of observing. None of these objects are included in either the Messier or the Caldwell catalogs, and all are visible in a 4-inch telescope under dark skies. Stunning photographs and beautiful drawings accompany detailed visual descriptions of the objects, which include their rich histories and astrophysical significance. The author's original finder charts are designed to help observers get to their targets fast and efficiently.

Deep-Sky Companions: Southern Gems

In Southern Gems, Stephen James O'Meara makes a detour beneath the southern skies, presenting a fresh list of 120 deep-sky objects for southern hemisphere stargazers to observe. Showcasing many exceptional objects catalogued by the pioneering observer James Dunlop, known as the 'Messier of the southern skies', all are visible through small- to moderate-sized telescopes or binoculars under dark skies. The list features some of the blackest dark nebulae, icy blue planetary nebulae and magnificent galaxies of all types. Each object is accompanied by beautiful photographs and sketches, original finder charts, visual histories and up-to-date astrophysical background information. Whether you live in the southern hemisphere or are just visiting, this new Deep-Sky Companion will make a perfect observing partner, whatever your background. There is no other southern sky guide like it on the market.

Deep-Sky Companions: The Messier Objects

The 110 galaxies, star clusters and nebulae catalogued by the comet hunter Charles Messier in the late 1700s are still the most widely observed celestial wonders in the heavens. They are the favourite targets of amateur astronomers, with such rich variety and detail that they never cease to fascinate. This book provides new and experienced observers with a fresh perspective on the Messier objects. Stephen James O'Meara has prepared a visual feast for the observer. Using the finest optical telescopes available for amateur work, superior eyepieces and the darkest site on Earth, he describes and sketches the view from the telescope as never before. There are new drawings, improved finder charts, and new astronomical data on each object, including findings from the Hubble Space Telescope. This is truly the Messier Guide for the modern age.

Sky and Ocean Joined

As one of the oldest scientific institutions in the United States, the US Naval Observatory has a rich and colourful history. This volume is, first and foremost, a story of the relations between space, time and navigation, from the rise of the chronometer in the United States to the Global Positioning System of satellites, for which the Naval Observatory provides the time to a billionth of a second per day. It is a story of the history of technology, in the form of telescopes, lenses, detectors, calculators, clocks and computers over 170 years. It describes how one scientific institution under government and military patronage has contributed, through all the vagaries of history, to almost two centuries of unparalleled progress in astronomy. Sky and Ocean Joined will appeal to historians of science, technology, scientific institutions and American science, as well as astronomers, meteorologists and physicists.
