42. ASP: Light Pollution light pollution. Such a loss might be acceptable if light pollution were the inevitableprice of progress, but it is not. Most sky glow is unnecessary. http://www.astrosociety.org/education/publications/tnl/44/lightpoll.html

No. 44 - Fall 1998 Light Pollution Villains of Lighting Heroes of Lighting Light Pollution and the U.S. National Science Education Standards Activity 1 ... Resources It is an unfortunate fact of today's life that most people are growing up unable to see the stars that our grandparents knew so well. The prime night sky exists only in pictures or at a planetarium. This is true not only in cities but also in suburbs and in rural areas where street lamps and other sources of "light pollution" have obscured our view of constellations, meteor showers, and even the planets. Indeed, many children and adults say after viewing the night sky for the first time in a really dark area away from a city that "it looks just like this in the planetarium." We have lost our view of the stars, and we have mucked up our nighttime environment as well. Such a loss might be acceptable if light pollution were the inevitable price of progress, but it is not. Most sky glow is unnecessary. The light that obscures our view of the night sky comes mainly from inefficient lighting sources that do little to increase nighttime safety, security, or utility. They produce only glare and clutter, costing more than one billion dollars annually in the U.S. alone. The Earth at night For astronomy and science, the impact has been even more dramatic. Astronomers require observations of extremely faint objects that can be made only with large telescopes at sites free of air pollution and urban sky glow. For example, scientists interested in how the universe was formed may study the light of galaxies and quasars at enormous distances from Earth. These images offer information about faraway corners of the universe, helping us understand how our own world was formed. Yet, after traveling countless lightyears, the light from these objects can be lost at the very end of its journey in the glare of our own sky.

PAWELSKI: Give me some examples of what you can do if you want to light things up at night in a way that you believe is appropriate. CRAWFORD: Never buy a light that looks like it's going to produce glare, for your front door or for your backyard. Shine the light where you need it and when you need it and without glare. So it's got to have a shield on it. If you can see the bulb, it's not a good light. For a streetlight, you want the light on the street not through somebody's bedroom window, not up into the sky. Put it where you need it, use the right amount, and shut it off if you don't need it. PAWELSKI: What's the issue with billboards?

LIGHT POLLUTION: WHEN THE NIGHT NEVER GETS DARK MAN-MADE LIGHT FLOODS THE NIGHT SKY, BLOTTING OUT THE MOON AND STARS, AND GLARING THROUGH THE BLINDS. Published: Thursday, January 4, 1996 Section: VIEWPOINT By DANIEL B. CATON, Special to The Observer           Imagine a National Park where we permitted the scenic views to be needlessly polluted with man-made refuse to the point where we could only barely see the most prominent features. Subtle valleys and glades are filled to the brim, with only the greatest peaks rising above a sea of litter. Suppose further that this trashing of the environment was not intentional, but allowed to advance even though the alternative is less costly and would save other natural resources.          This park is not official, but also not imaginary - it's very real. And, it's in your backyard. More exactly, it is above your yard: It is the night sky.

It turns out we need the darkness to make our immune systems work. Darkness for Health Scientists have now discovered that only when it's really dark can your body produce the hormone called melatonin. Melatonin fights diseases, including breast and prostate cancer.

Do you agree? DON DYBUS : I think the term "light pollution" is a misnomer because in the morning the sun comes up and burns it all off, and we're not really talking about any toxins. So it's an aesthetic thing for the general public. For the scientific community, it does have an impact because of the research that goes on here. Tucson put a moratorium on new billboards back in 1985. The billboard business hasn't added to any of the problem in 17 years. We have a self-imposed deadline, and typically turn our billboards off at 11 p.m. PAWELSKI: Why do you do that?

You Are Here: Welcome to the Irish Light Pollution Awareness Campaign website! ILPAC is the Irish Section of the International Dark Sky Association , and was formed at the 2003 Whirlpool Star Party in Birr, Co. Offaly, Ireland. We are promoting awareness of light pollution and working to reduce bad lighting throught the country which as you can see from the image below still has relativly dark skies compared to the rest of Europe. We have written several articles and submissions to various county councils and government bodies which are available in our Resources Section, but we need more help. We cannot possibly keep an eye on all planning developments in the country so we need people to help us at a local level by watching for any development plans that they think they can influence to use better lighting at an early stage, after all its your skies! ILPAC will keep a set of all documents that have been written here so as to make the job of writing to councils and developers as easy as possible for you. And if you have some questions about lighting procedures, or some jargon that is used in planning, let us know and we will find out the information for you and post it here. Albert White

Our Vanishing Night Earth at Night - NASA image (click on image to enlarge) Erosion of the Night Sky from Light Pollution "I remember camping as a kid when we could see so many stars you couldn't tell one constellation from the next, and the Milky Way was a river of light". "It was so dark you could hardly see your hand in front of your face, and I saw my shadow on the ground from Venus!" The lucky ones among us have probably made these claims, but sights such as this are becoming increasingly rare. Only a generation ago, many could still see the Milky Way from their backyards. Unfortunately, the overuse and poor quality of modern outdoor lighting is fast destroying a valuable natural resource - a dark nighttime sky. The light pollution that results from this misuse is, however, the easiest of pollution sources to fix.

Study details growing problem of light pollution BY JEFF FOUST SPACEFLIGHT NOW Posted: August 18, 2001 Italian and American scientists have quantified what most urban-dwelling observers have become painfully aware of: that the increasing use of artificial lights has wiped out clear views the night sky for hundreds of millions of people. The First World Atlas of Artificial Night Sky Brightness, to be published in a future issue of the Monthly Notices of the Royal Astronomical Society, provides the most detailed study to date of the effects of light pollution: artificial lights that drown out the natural light of the night sky. "Large numbers of people in many countries have had their vision of the night sky severely degraded," noted Pierantonio Cinzano of the University of Padua, who co-authored the study with Fabio Falchi of Padua and Chris Elvidge of the US National Oceanic and Atmospheric Administration. Moreover, Cinzano added, "our atlas refers to the situation in 1996-97. It is undoubtedly worse today." According to their study, two-thirds of the world population lives with some form of light pollution. The situation is worse in industrialized nations: 97 percent of people the United States and 96 percent of those living in the European Union live with skies that never get darker than nights with a half Moon under otherwise ideal conditions.
