Light pollution has spread so much in the last few decades that it often compromises our view of the stars. It is becoming more and more difficult to find an observing site with clear, dark skies away from light and industrial pollution. However, with patience, some simple equipment, and by choosing the right targets to observe, amateur astronomers can still find observing from towns and cities a rewarding hobby. The result of thirty years of observing the night sky from within a city, Denis Berthier s practical guide will help amateur astronomers to enjoy their hobby without having to travel to distant sites, and without using complicated equipment or difficult techniques, enabling them to observe and photograph stars and planets as well as many other celestial objects.
Did you know that stars are seasonal? That Orion is one of the brightest constellations? That a single day on Venus is longer than an entire year on Venus? Space has captivated mankind since the beginning of time. Fifty years ago, Neil Armstrong became the first man to step on the moon and since then our knowledge of astronomy has continued to expand. With so many mysteries yet to be solved, science journalist Abigail Beall takes readers on an astonishing journey though the landscape of space. In The Art of Urban Astronomy, you will be guided through the seasons and learn about the brightest stars and constellations, the myths and legends of astronomy and how to identify star clusters and galaxies with just your eyes or a pair of binoculars. For urban dwellers wrapped up in the rush and bustle of the city, it can be calming and truly valuable to take the time simply to stop, look and reconnect with nature. Packed full of seasonal star charts, constellation charts and fascinating facts, this is the perfect guide for those who have looked up at the night sky and don't know where to begin. After reading this book, you'll never look up in the same way again.
Philip's The Urban Astronomy Guide provides the ideal introduction to the fascinating hobby of astronomy for the town dweller. These days, you don't have to live close to a city or town centre to suffer from the effects of light pollution. From your back garden or rooftop observing site, your night sky will be illuminated by light from the surrounding city or town. And while, like everyone else, you will have to contend with the vagaries of the weather, you will have the added problem of poor air quality. But despite these difficulties, there is still a host of celestial delights to be seen! In this book, author Robin Scagell shows that night-time lighting and the resultant brightening of the sky can be combated, and demonstrates how to make the best of poor conditions. Although the unaided eye may be able to pick out only a few hundred stars, binoculars or a small telescope will reveal many times that number. A little optical aid can also give you good views of every type of major astronomical object, including star clusters, nebulae and galaxies. For example, for those who want to develop their interest further, there are special filters that let through the light from distant nebulae while blocking out wavelengths infested by unwanted stray light from streetlights. And modern CCDs allow modest amateur telescopes to penetrate the urban sky glow and reveal sights that would have taxed the largest professional instruments only 30 years or so ago. Philip's The Urban Astronomy Guide will show you how to get the most out of almost any sky with whatever equipment you have, or even with none at all.
Offers amateur astronomers a guide to techniques and available technologies for observing the night sky from an urban location, discussing optimal weather conditions, ways to reduce the effects of light, different types of telescopes, and readily seen celestial bodies
The ideal introduction to astronomy in the city. These days, skywatchers do not have to live close to a city or town center to suffer from the effects of light pollution. According to the National Park Service, city lights as far as 200 miles away diminish views of night skies. So even in a remote field, the sky above may be part of the "sky glow" of the surrounding city or town. Weather might be an issue too, as it is for all skywatchers. Nevertheless, there are many celestial delights to be seen. Urban Astronomy shows that nighttime lighting and the resultant brightening of the sky can be combatted and demonstrates how to make the best of poor conditions. Although the unaided eye may be able to pick out only a few hundred stars, binoculars or a small telescope will reveal many times that number. A little optical aid can also give you good views of every type of major astronomical object, including star clusters, nebulae and galaxies. For example, there are special filters that let through the light from distant nebulae while blocking out wavelengths infested by unwanted stray light from streetlights. Modern CCDs allow modest amateur telescopes to penetrate the urban sky glow and reveal sights that would have taxed larger instruments 30 years ago. The book also covers: How weather and pollution affect observing Specific tips to combat urban streetlighting The best objects to observe from cities and towns Deep-sky objects visible from urban locations in both the northern and southern hemispheres The range of telescopes and accessories for light-polluted skies CCDs and the rebirth of astronomy from cities and towns How to find dark skies. The book's nine chapters cover the basics of successful urban viewing, its "enemies" -- weather and streetlights -- and explain how to choose viewing targets and arm yourself with the right "weapons and ammunition" to find them. The book also covers indoor astronomy. Urban Astronomy is an ideal guide to skywatching while combating light pollution. It will show you how to get the most out of almost any sky.
Fun, Outrageous Space Stories, Debunked! In this Internet age where science fiction masquerades as fact, even the most rational person might find themselves wondering: Could NASA have faked the moon landings? Are we sure the government isn’t using chemtrails to experiment on people? And did NASA really spend millions on “space pens”? Urban Legends from Space cuts through the fog of myth to bring the truth behind these questions, and 48 other celestial legends, out into the open. In examining the shaky claims behind these many misconceptions and taking us step-by-step through the concrete evidence that contradicts them, expert Bob King debunks each myth and exposes the scientific truth at its core. Along the way, King offers us the tools we need to become more discerning observers of the world around us and more responsible sharers of information overall.
A complete guide for the amateur astronomer living in an urban or suburban center… The Urban Astronomer If you think a trip to the country is necessary to observe celestial objects, take a second look. Viewing the sky from an urban location can be just as fun and educational — if you know how to go about it. The Urban Astronomer shows amateur and more advanced astronomers the best ways and times to observe celestial objects from a city or suburban environment. Complete with detailed illustrations, The Urban Astronomer: Shows readers how to overcome the special problems of viewing the sky from cities and suburbs, such as light pollution Describes in detail those objects most easily viewed from a city location Includes many sky activities that can be enjoyed by novice and experienced urban astronomers Provides helpful tips and checklists for preparing your own stargazing outing Covers objects for naked-eye observation as well as those that need binoculars or telescopes and describes the best equipment for the urban stargazer
This book covers the "why," "how," and "what" of astronomy under light-polluted skies. The prospective city-based observer is told why to observe from home (there are hundreds of spectacular objects to be seen from the average urban site), how to observe the city sky (telescopes, accessories, and moderns techniques), and what to observe. About half of the book is devoted to describing "tours" of the sky, with physical and observational descriptions, at-the-eyepiece drawings, and photographs.
The four decades between the two Universal Exhibitions of 1888 and 1929 were formative in the creation of modern Barcelona. Architecture and art blossomed in the work of Antoni Gaudi and many others. At the same time, social unrest tore the city apart. Topics such as art nouveau and anarchism have attracted the attention of numerous historians. Yet the crucial role of science, technology and medicine in the cultural makeup of the city has been largely ignored. The ten articles of this book recover the richness and complexity of the scientific culture of end of the century Barcelona. The authors explore a broad range of topics: zoological gardens, natural history museums, amusement parks, new medical specialities, the scientific practices of anarchists and spiritists, the medical geography of the urban underworld, early mass media, domestic electricity and astronomical observatories. They pay attention to the agenda of the bourgeois elites but also to hitherto neglected actors: users of electric technologies and radio amateurs, patients in clinics and dispensaries, collectors and visitors of museums, working class audiences of public talks and female mediums. Science, technology and medicine served to exert social control but also to voice social critique. Barcelona: An urban history of science and modernity (1888-1929) shows that the city around 1900 was both a creator and facilitator of knowledge but also a space substantially transformed by the appropriation of this knowledge by its unruly citizens.
