Book Excerpt :

Much of what is known about the universe came from the study of celestial shadows. This book looks in detail at the way eclipses and other celestial shadows have given us amazing insights into the nature of the objects in our solar system and how they are even helping us discover and analyze planets that orbit stars other than our Sun. A variety of eclipses, transits, and occultations of the mooons of Jupiter and Saturn, Pluto and its satellite Charon, asteroids and stars have helped astronomers to work out their dimensions, structures, and shapes - even the existence of atmospheres and structures of exoplanets. Long before Columbus set out to reach the Far East by sailing West, the curved shadow of the Earth on the Moon during a lunar eclipse revealed that we inhabit a round world, a globe. More recently, comparisons of the sunlit and Earthlit parts of the Moon have been used to determine changes in the Earth's brightness as a way of monitoring possible effects in cloud coverage which may be related to global warming. Shadows were used by the Greek mathematician Eratosthenes to work out the first estimate of the circumference of the Earth, by Galileo to measure the heights of the lunar mountains and by eighteenth century astronomers to determine the scale of the Solar System itself. Some of the rarest and most wonderful shadows of all are those cast onto Earth by the lovely "Evening Star" Venus as it goes between the Earth and the Sun. These majestic transits of Venus occur at most two in a century; after the 2012 transit, there is not a chance to observe this phenomenon until 2117, while the more common sweep of a total solar eclipse creates one of the most dramatic and awe-inspiring events of nature. Though it may have once been a source of consternation or dread, solar eclipses now lead thousands of amateur astronomers and "eclipse-chasers" to travel the globe in order to experience the dramatic view under "totality." These phenomena are among the most spectacular available to observers and are given their full due in Westfall and Sheehan's comprehensive study.

Book Short Summary:

In this book Astronomy Magazine editor Michael Bakich presents all the information you’ll need to be ready for the total solar eclipse that will cross the United States on August 21, 2017. In this one resource you’ll find out where the eclipse will occur, how to observe it safely, what you’ll experience during the eclipse, the best equipment to choose, how to photograph the event, detailed weather forecasts for locations where the Moon’s shadow will fall, and much more. Written in easy-to-understand language (and with a glossary for those few terms you may not be familiar with), this is the must-have reference for this unique occurrence. It’s not a stretch to say that this eclipse will prove to be the most viewed sky event in history. That’s why even now, more than a year before the eclipse, astronomy clubs, government agencies, cities — even whole states — are preparing for the unprecedented onslaught of visitors whose only desire is to experience darkness at midday. Bakich informs observers what anyone will need to observe, enjoy, and understand this event.

The Hatfield SCT Lunar Atlas

Book Short Summary:

In 2004, it became obvious that Henry Hatfield’s original atlas wasn’t suitable for all current commercially-made amateur telescopes. Newtonian telescopes and astronomical refractors – for many years the only choice for amateurs – invert the observed image. The standard Hatfield Atlas therefore follows the IAU (International Astronomical Union) convention of having maps (and photographs) with South at the top and West on the left: an inverted image. However, the current ranges of Schmidt-Cassegrain and Maksutov telescopes – that’s most of those manufactured by Meade, Celestron, and many others – don’t invert the observed image but instead reverse it left-for-right. That’s with North at the top and East on the left. Because of the way the human visual system works, it is almost impossible to mentally ‘mirror-image’ a map to compare it with the view through the eyepiece , so even turning an IAU-standard atlas upside-down doesn’t help! This new SCT version of the Atlas solves this problem for observers. Identification of lunar features is made quick and easy. The new, digitally re-mastered second edition vastly improves the clarity and definition of the original photographs – significantly beyond the resolution limits of the photographic grains present in earlier atlas versions – whilst preserving the layout and style of the original publications. This has been achieved by merging computer-visualized Earth-based views of the lunar surface, derived from NASA’s Lunar Reconnaissance Orbiter data, with scanned copies of Commander Hatfield’s photographic plates, using the author’s own software. The result is a The Hatfield SCT Lunar Atlas for 21st century amateur telescopes up to and beyond 12-inch aperture. It contains all the features that made the original so widely used: a combination of an index of all International Astronomical Union named primary lunar features, and twelve chart areas help to locate any named lunar features of interest that can each be examined under typically five different states of illumination. Close ups of interesting features are also included. The new Atlas is supplemented by an introduction to its use, a short description of the digital re-mastering technique, and a completely new section describing lunar observing techniques. At the end of the atlas there is an index of all named features and crater diameters, along with a summary table of the dates and times that the original Hatfield images represent.

Book Short Summary:

"The Hatfield Lunar Atlas" has become an amateur lunar observer's bible since it was first published in 1968. A major update of the atlas was made in 1998, using the same wonderful photographs that Commander Henry Hatfield made with his purpose-built 12-inch (300 mm) telescope, but bringing the lunar nomenclature up to date and changing the units from Imperial to S.I. metric This edition is important since the fact is that modern telescope optics, digital imaging equipment and computer enhancement can easily surpass what was achieved with Henry Hatfield's 12-inch telescope and a film camera. This limits the usefulness of the original atlas to visual observing or imaging rather small amateur telescopes. The new, digitally re-mastered edition vastly improves the clarity and definition of the original photographs - significantly beyond the resolution limits of the photographic grains present in earlier atlas versions - while preserving the layout and style of the original publications. This has been achieved by merging computer-visualized Earth-based views of the lunar surface, derived from NASA's Lunar Reconnaissance Orbiter data, with scanned copies of Commander Hatfield's photographic plates, using the author's own software. The results is a "The Hatfield Lunar Atlas" for 21st century amateur telescopes up to and beyond 12-inch aperture.

Book Short Summary:

The Oxford English Dictionary contains 175,000 words in common usage and yet linguists estimate that a vocabulary of 3,000 is sufficient to cover ninety-five per cent of common usage in speech and print. Where have all those other words gone? The English language is a giant sponge, absorbing words from a multitude of different languages and cultures and yet it seems speakers of English are indolent at accessing the rich resources at our disposal. 1000 Words to Expand Your Vocabulary aims to ameliorate this issue by providing a fascinating lexicography to boost your word power. Alongside the elegant and archaic words are discussions of malapropisms and solecisms, words for which meaning has changed over time and words that have meanings often contrary to their common usage (and abusage). Each entry contains outlines of word origins, examples in context and a wealth of word related trivia. 1000 Words to Expand Your Vocabulary will help word lovers flaunt their prolixity without flouting the rules that govern correct meaning.
