Light-pollution is the modern scourge of optical astronomy. An increasing number of observing sites are in danger of being rendered useless due to the glare of city lighting blotting out the night sky. Professional astronomical observatories are located far from cities, but amateur astronomers often do not have this luxury. This book considers the two available strategies open to Astronomers. The first involves campaigning against light pollution by lobbying Authorities and Standards Organisations, and the second involves using the correct instrumentation. The book contains an extensive detailed catalogue of deep-sky and other objects that - despite what one might believe - can be seen from variously light-polluted sites, for practical observers.
The first practical guide to alleviating an increasingly prevalent environmental concern.
Constituting the first holistic overview including practical remedies, this handbook provides the background needed by anyone grappling with the complex issue of outdoor lighting and its effects. It describes not only the problems that astronomers and other night sky observers face in reducing the problems of information loss due to light pollution, as well as the problems lighting technologists face in optimising outdoor lighting installations that cause little or no light pollution. The first part is directed to decision makers and managers of outdoor space and covers the areas of general interest, culminating in recommendations to reduce the impact of light pollution. The second part is directed primarily to scientists and engineers, as a support to the design and maintenance of outdoor lighting installations, with special reference to astronomical observations. Elaborating issues from the first part, these contributions include examples that refer to specific outdoor lighting projects and to more general policy and educational measures. Written for designers of lighting equipment and managers of astronomical observatories, but also aimed at the authorities and decision makers responsible for the organization and maintenance of the public space, it will serve a good purpose in graduate or postgraduate curricula for scientists, engineers, economists and law students. This handbook fills the gap that exists between astronomical textbooks, engineering texts and popular brochures about light pollution.
After decades "in the shadows", urban lighting is re-emerging as a matter of public debate. Long-standing truths are increasingly questioned as a confluence of developments affects lighting itself and the way it is viewed. Light has become an integral element of place-making and energy-saving initiatives alike. Rapidly evolving lighting technologies are opening up new possibilities, but also posing new challenges to planners, and awareness is growing that artificial illumination is not purely benign but can actually constitute a form of pollution. As a result, public policy frameworks, incentives and initiatives are undergoing a phase of innovation and change that will affect how cities are lit for years to come. The first comprehensive compilation of current scientific discussions on urban lighting and light pollution from a social science and humanities perspective, Urban Lighting, Light Pollution and Society contributes to an evolving international debate on an increasingly controversial topic. The contributions draw a rich panorama of the manifold discourses connected with artificial illumination in the past and present – from early attempts to promote new lighting technologies in the late 19th and early 20th centuries to current debates on restricting its excessive usage in public space and the protection of darkness. By bringing together a cross-section of current findings and debates on urban lighting and light pollution from a wide variety of disciplines, it reflects that artificial lighting is multifaceted in its qualities, utilisation and interpretation. Including case studies from the United States, Europe, and the UK, Urban Lighting, Light Pollution and Society is one of the first to take a serious assessment of light, pollution, and places and is a valuable resource for planners, policy makers and students in related subjects.
While certain ecological problems associated with artificial night lighting are widely known-for instance, the disorientation of sea turtle hatchlings by beachfront lighting-the vast range of influences on all types of animals and plants is only beginning to be recognized. From nest choice and breeding success of birds to behavioral and physiological changes in salamanders, many organisms are seriously affected by human alterations in natural patterns of light and dark. Ecological Consequences of Artificial Night Lighting is the first book to consider the environmental effects of the intentional illumination of the night. It brings together leading scientists from around the world to review the state of knowledge on the subject and to describe specific effects that have been observed across a full range of taxonomic groups, including mammals, birds, reptiles and amphibians, fishes, invertebrates, and plants. Ecological Consequences of Artificial Night Lighting provides a scientific basis to begin addressing the challenge of conserving the nighttime environment. It cogently demonstrates the vital importance of this until-now neglected topic and is an essential new work for conservation planners, researchers, and anyone concerned with human impacts on the natural world.
Light pollution (light smog, light pollution or light emissions) is a fundamental problem in metropolises with effects on flora, fauna and people. Accordingly, the first section of the book discusses the basics of light pollution and its effects on various organisms. The characteristics of light smog in the cities of Hanover, Warsaw, Boston, New York City and Toronto are then analysed and compared. But how can the problem be tackled? Existing measures for the prevention of light pollution are discussed and further novel approaches are shown by comparing the metropolises. The book is aimed primarily at practitioners in this field and helps to identify sources of emissions and identify suitable reduction measures. This book is a translation of the original German edition „Lichtverschmutzung in Metropolen“ by Emlyn Etienne Goronczy, published by Springer Fachmedien Wiesbaden GmbH in 2018. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.
A deeply panoramic tour of the night, from its brightest spots to the darkest skies we have left. A starry night is one of nature's most magical wonders. Yet in our artificially lit world, three-quarters of Americans' eyes never switch to night vision and most of us no longer experience true darkness. In The End of Night, Paul Bogard restores our awareness of the spectacularly primal, wildly dark night sky and how it has influenced the human experience across everything from science to art. From Las Vegas' Luxor Beam -- the brightest single spot on this planet -- to nights so starlit the sky looks like snow, Bogard blends personal narrative, natural history, science, and history to shed light on the importance of darkness -- what we've lost, what we still have, and what we might regain -- and the simple ways we can reduce the brightness of our nights tonight.
Assesses the current status, and future challenges and opportunities, of the ecological study, design and management of cities and towns.
This book takes a close look at our relationship with the sky, the stars, light and darkness. In particular, it examines how light pollution has interfered with the culture of astronomy and our ability to appreciate this essential facet of our natural world. The sky has always held significance for humanity, in both cultural and scientific terms. And yet we persistently pollute it with (sometimes unnecessary) light in our obsessive desire to chase away the darkness. This effectively switches off the stars, hampering our ability to enjoy one of the most inspiring sights nature has to offer to humankind. In addition, too much light is hazardous to both our health and that of the fauna and flora of this planet. This book also features a comprehensive look at the current controversy regarding efforts to expand internet access through the launch into low Earth orbits of thousands of new satellites, which will pollute the night with moving lights while filling to saturation the capability of the circumterrestrial space. This conflict does not mean that the interests of astronomy and those of space technology have to be at odds, and potential compromises are explored between the satellite initiative and the desire to maintain a dark, radio silent sky.
In a world marred by light pollution, this quest for true darkness is a clarion call to turn out the lights--so that all may see.
