| sky and telescope magazine free download: Silent Sky Lauren Gunderson, 2015-01-01 THE STORY: When Henrietta Leavitt begins work at the Harvard Observatory in the early 1900s, she isn’t allowed to touch a telescope or express an original idea. Instead, she joins a group of women “computers,” charting the stars for a renowned astronomer who calculates projects in “girl hours” and has no time for the women’s probing theories. As Henrietta, in her free time, attempts to measure the light and distance of stars, she must also take measure of her life on Earth, trying to balance her dedication to science with family obligations and the possibility of love. The true story of 19th-century astronomer Henrietta Leavitt explores a woman’s place in society during a time of immense scientific discoveries, when women’s ideas were dismissed until men claimed credit for them. Social progress, like scientific progress, can be hard to see when one is trapped among earthly complications; Henrietta Leavitt and her female peers believe in both, and their dedication changed the way we understand both the heavens and Earth. |

| sky and telescope magazine free download: Weird Weather David A. J. Seargent, 2012-03-02 This book is, in a sense, a sequel to David Seargent's first Springer book Weird Astronomy (2010). Whereas Weird Astronomy extended over a broad range of purely astronomical topics, the present work concentrates on phenomena closer to home; the atmospheric and shallow space events as opposed to deep space events. The line between astronomy and meteorology is blurred - a fact that is discussed in Weird Weather. It is not primarily a book of wonders or of the unexplained, although some of the topics covered remain mysteries. It is primarily directed toward those who are fascinated by climate and weather, and who are open-minded when considering Earth's climate, what drives it, and what are the causes of climate change. The author, David A. J. Seargent, presents the facts with a balanced and scientific approach. Weird Weather: Tales of Astronomical and Atmospheric Anomalies is about strange, unusual, and apparently inexplicable observations of the air and sky. Primarily these are in the Earth's atmosphere, but there are corresponding phenomena in the atmospheres of other planets of the Solar System - lightning on Venus, Jupiter, and Saturn, whirlwinds and dust storms of Mars, and auroras on Jupiter. Topics include anomalous lights, anomalous sounds, spectacular effects of cloud illumination by the Sun or Moon, lightning phenomena, electrophonic sounds of lightning, aurora and meteors, tornado and whirlwind phenomena on Earth and Mars, usual atmospheric effects, mirages, and the possible astronomical influences on cloud and climate. |

She read every book on astronomy she could find and even started her own neighborhood astronomy club for girls. But many of the people around her didn't think science was the right field for a woman. Academic advisers in high school and even college tried to dissuade Roman from pursuing astronomy. She worked hard to eventually become NASA's first Chief of Astronomy and, ultimately, the Mother of Hubble. Learn how Roman's passion for astronomy and her tireless work on the Hubble Space Telescope project helped scientists capture breathtaking images of deep space. |

| sky and telescope magazine free download: Einstein's Shadow Seth Fletcher, 2018-10-09 Einstein’s Shadow follows a team of elite scientists on their historic mission to take the first picture of a black hole, putting Einstein’s theory of relativity to its ultimate test and helping to answer our deepest questions about space, time, the origins of the universe, and the nature of reality Photographing a black hole sounds impossible, a contradiction in terms. But Shep Doeleman and a global coalition of scientists are on the cusp of doing just that. With exclusive access to the team, journalist Seth Fletcher spent five years following Shep and an extraordinary cast of characters as they assembled the Event Horizon Telescope, a worldwide network of radio telescopes created to study black holes. He witnessed the team’s struggles, setbacks, and breakthroughs, and, along the way, Fletcher explored the latest thinking on the most profound questions about black holes: Do they represent a limit to our ability to understand reality? Or will they reveal the clues that lead to the long-sought theory of everything? Fletcher transforms astrophysics into something exciting, accessible, and immediate, taking us on an incredible adventure to better understand the complexity of our galaxy, the boundaries of human perception and knowledge, and how the messy endeavor of science really works. Weaving a compelling narrative account of human ingenuity with excursions into cutting-edge science, Einstein’s Shadow is a tale of great minds on a mission to change the way we understand our universe—and our place in it. |

| sky and telescope magazine free download: Choosing and Using a Refracting Telescope Neil English, 2010-09-28 Choosing and Using a Refracting Telescope has been written for the many amateur astronomers who already own, or are intending to purchase, a refracting telescope – perhaps to complement their existing arsenal of larger reflecting telescopes – or for the specialist who requires a particular refractor for serious astronomical applications or nature studies. Four hundred year ago, during the winter of 1609, a relatively unknown Italian scientist, Galileo Galilei designed a spyglass with two crude lenses and turned it skyward. Since then, refractors have retained their dominance over all types of reflector in studies of the Moon, planets and double stars because of the precision of their optics and lack of a central obstruction in the optical path, which causes diffraction effects in all commercially-made reflectors. Most mature amateur astronomers got started with a 60mm refractor, or something similar. Thirty years ago, there was little choice available to the hobbyist, but in the last decade long focus crown-flint achromats have moved aside for some exquisitely crafted apochromatic designs offered by leading commercial manufacturers. There has been a huge increase in the popularity of these telescopes in the last few years, led by a significant increase in the number of companies (particularly, William Optics, Orion USA, StellarVue, SkyWatcher and AstroTech) who are now heavily marketing refractors in the amateur astronomical magazines. In Choosing and Using a Refracting Telescope, well-known observer and astronomy writer Neil English celebrates the remarkable history and evolution of the refracting telescope and looks in detail at the instruments, their development and their use. A major feature of this book is the way it compares not only different classes of refractor, but also telescopes of each class that are sold by various commercial manufacturers. The author is perhaps uniquely placed to do this, having used and tested literally hundreds of different refracting telescopes over three decades. Because it includes many diverse subjects such as imaging with consumer-level digital cameras, imaging with webcams, and imaging with astronomical CCD cameras – that are not covered together in equal depth in any other single volume – Choosing and Using a Refracting Telescope could become the ‘refractor bible’ for amateur astronomers at all levels, especially those who are interested in imaging astronomical objects of every class. |

Searching more for a learned appreciation of nature and our exact place within the cosmos than academic scientific knowledge, science and travel writer Jamie Carter takes the reader on a 12 month tour of the night sky's incredible annual rhythms that say so much about Earth. During the journey he learns about the celestial mechanics at work in the skies above that are – to the beginner – almost beyond belief. As well as the vital constellations and clusters, and the weird and wonderful nebulas, he searches out “dark sky destinations” across the globe that help increase knowledge and give a new perspective on familiar night sky sights. On the journey he witnesses a solar eclipse and grapples with star-charts, binoculars, smartphone apps, telescopes, spots satellites and attempts basic astro-photography. By year's end, the reader will be able to glance at the night sky from anywhere on the planet and tell what direction he or she is facing, what time it is, where all the planets are and even where the Galactic Center Point is. |

| sky and telescope magazine free download: Grab 'n' Go Astronomy Neil English, 2014-05-14 Like everyone else, most amateur astronomers live busy lives. After a long day or work or looking after young children, the last thing you want as an observer is to have to lug out a large telescope and spend an hour getting it ready before it can be used. Maybe you are going on vacation somewhere in the countryside where there are sure to be dark skies, but you don’t necessarily want astronomy to dominate the trip. Or suppose you are not quite committed to owning a large telescope, but curious enough to see what a smaller, portable setup can accomplish. These are times when a small “grab ’n’ go” telescope, or even a pair of binoculars, is the ideal instrument. And this book can guide you in choosing and best utilizing that equipment. What makes a telescope fall into the “grab ’n’ go” category? That’s easy – speed of setting up, ease of use, and above all, portability. In Part I of this book, we survey the various types of equipment, including accessories and mounts, that are available, and what it is best for what kind of viewing. Part II is about using your grab ’n’ go telescope to visit a wealth and wide variety of objects. There are chapters on solar, lunar and planetary observing, as well as descriptions of many deep sky objects, including double and variable stars, planetary, emission and reflection nebulae, open and globular clusters and distant galaxies. This ambitious text is dedicated to those who love to or – because of their limited time – must observe the sky at a moment’s notice, whether from the comfort of a backyard or while on business or vacation far from home. Everything you need to know is here. So get started!. |

A new index makes finding targets easier than ever before, while the selection of viewing targets has been revised from the first edition. Most of all, this book is all about how to enjoy astronomy. The author's enthusiasm and sense of wonder shine through every page as he invites you along on a tour of some of the most beautiful and fascinating sites in the deep sky, with the improved object list making sure your choice of a faint cluster, hazy nebula or distant galaxy will all be equally rewarding. |
