The Fading Milky Way Light pollution is a growing environmental problem that threatens to erase the night sky before its time. Listen to this story via streaming audio , a downloadable file , or get help November 1, 2001: Cosmologists speculate that 10 years from now (a mind-boggling stretch) the stars in our relentlessly expanding Universe could run out of fuel and fade from view. The night sky, once the TV set of ancient peoples, will become dull and boring: a blank tableau with no stars or nebulae. Sounds like an astronomer's nightmare! Fortunately, the stars themselves won't go out for a very long time. But researchers say the night sky is already fading. A recent study revealed that perhaps two-thirds of the world's population can no longer look upwards at night and see the Milky Way a hazy swath of stars that on warm summer nights spans the sky from horizon to horizon.

Science@NASA home Cosmic Light Pollution A series of unmanned balloon flights will measure the subtle ultraviolet glow of the night sky and help unravel one of the most perplexing mysteries of astrophysics. July 10, 2000 A midnight balloon ride high above the farms and fields of the American West to view the gentle glow of the Earth at night may sound rather romantic. The ride from Palestine, Texas on July 6, 2000, however, was pure science, the first of a series of unmanned NASA scientific balloon flights that will measure the ultraviolet (UV) light illuminating the night sky and that may ultimately help solve the mystery of high-energy cosmic rays, which seem to travel through space further than physicists deem possible. The balloon carried an experiment called NIGHTGLOW , a collaboration between NASA's Goddard Space Flight Center (Greenbelt, MD.) and the University of Utah, Salt Lake City. NIGHTGLOW is designed to detect background radiation produced by a variety of sources, including moonlight and starlight, the interaction of oxygen and nitrogen molecules in the atmosphere, human-made lighting, and even the bioluminescence of squid and other animals.

83. The Astronomical Society Of Malta [Sub Groups] Explains how light pollution can and is been controlled in Malta. Lots of links. LPAG is a part of The Astronomical Society Of Malta. http://www.maltastro.org/lpag/

Introduction The LPAG has been recently formed within The Astronomical Society of Malta. Its aims are to create first of all an awareness about light pollution and its adverse effects on man and on local fauna and flora. This will be done by the publication of several leaflets about the subject, together with the publication of an update to the guidance for outdoor lighting booklet which the Society had issued back in 1995. Many outdoor lights waste energy by spilling much of their light where it is not needed, such as up into the sky. This waste results in high operating costs. L.P.A.G. has come up with a set of guidelines for the protections of our night skies. Click here to read the guidelines. Together with local Environmental Groups in Malta The LPAG is studying the effects of light pollution on the Flora and Fauna. Various studies show that light pollution threatens the natural environment. Click here to read some of the studies.

Light Pollution, Page 2 Villains and Heroes of Lights and Lighting Fixtures If we are to reduce the effects of light pollution, we must learn about the types, both good and bad, of fixtures used in outdoor lighting. Some of these are heroes: They save energy, direct light to where it is needed, and add to the ambiance of our nighttime environment. Others are villains that waste energy, spill light in all directions, produce glare, and ruin the beauty of the night. the Villains Globes and similar fixtures. These usually consist of a transparent or translucent "ball" or cylinder with a lamp bulb inside, sitting atop a pole. They look attractive in the daytime when they are not turned on. In fact, this type of fixture is often chosen for this very reason. These lights are villains because when turned on at night, they radiate not only in the direction where illumination is needed, but in all directions - more than half the light is directed upward to add to the sky glow and sideways to cause glare. Much of the rest is not doing any useful work in helping us see the things we need. Tripping the light (not-so) fantastic. View of Los Angeles, CA in 1908 (top) and 1988 (bottom).

The House of Commons science and technology committee have criticised the government for an "inconsistent approach" to the issue. In their latest report, the MPs also criticise local authorities for failing to tackle the issue of light pollution. "There are too many local planning authorities which have not taken the issue of light pollution seriously." The politicians highlight the impact of light on astronomy while drawing attention to the way such pollution affects people's enjoyment of star-filled skies. Clamp down Home Office evidence that suggests public lighting reduces crime is also questioned in the report. The MPs called on the government to address energy waste caused by over-powerful lighting and to clamp down on growing light pollution. Their recommendations include: Making obtrusive light a statutory nuisance and enabling action against neighbours who seriously light pollute.

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.

This "light pollution" wastes energy and provides no benefit to society. Light Pollution is misused or misdirected light: Sky Glow .............is light wastefully escaping into the night sky and causing a glow over urban/suburban areas Glare ....................is light shining dangerously out into peoples eyes as they walk or drive by. Light Trespass .....is unwanted light shining onto a neighbors property or into their house. Light Pollution wastes billions of dollars annually in the United States wastes incredible amounts of valuable natural resources pollutes the air we breath through needless generation of electricity (most of which comes from fossil fuels) harms nocturnal wildlife harms humankind, being linked to some serious ailments destroys the views of the heavens that man has enjoyed since the beginning of time.

Contact Us Front Page Light Pollution Taking Toll on Wildlife, Eco-Groups Say Sharon Guynup National Geographic Today April 17, 2003 Birds At Risk Artificial lighting seems to be taking the largest toll on bird populations. Nocturnal birds use the moon and stars for navigation during their bi-annual migrations. "When they fly through a brightly-lit area, they become disoriented," said Michael Mesure, executive director of the Fatal Light Awareness Program (FLAP), a Toronto-based environmental organization. The birds often crash into brilliantly-lit broadcast towers or buildings, or circle them until they drop from exhaustion. "Over 450 bird species that migrate at night across North America are susceptible to collisions with night-lit towers, including threatened or endangered species like the cerulean warbler and Henslow's sparrow," Mesure said. Sometimes whole flocks collide with over-lit structures. According to Mesure, over two consecutive nights in 1954, 50,000 birds died at Warner Robins Air Force Base, Georgia, when they followed lights straight into the ground. And in 1981, over 10,000 birds slammed into floodlit smokestacks at the Hydrox Generating Plant near Kingston, Ontario.

Our members are active observers in Oregon and Southern Washington. IDA Newsletters Why are engineers, medical professionals, and amateur astronomers, concerned about the effects of Light Pollution? Some studies show: the effects of not sleeping in total darkness can degrade the immune system of animals and humans. Poor lighting and wasted energy is misuse of electricity and money. Misdirected light, 'Light Trespass' is a nuisance and architecturally unappealing. Studies show that various uses of lighting may actually increase crime, just exactly the opposite of what people try to achieve. The light pollution from inferior lighting design on highways creates a hazard to driving known as 'Road Glare.' The light polluted night sky is a priceless educational resource lost to poor lighting management. RCA has a slide show created by the International Dark Sky Association which is available by request. These slides show different lighting techniques and their effect on the night sky.

Tourtellot National Geographic Traveler Updated March 19, 2004 At 3 a.m. my wife felt the call, pulled on some clothes, stepped outside, and stopped cold. "Come here!" she whispered. I did. She simply pointed up. "Blazing with stars" doesn't capture it. Stars upon stars upon stars, a million far-flung suns, in a night so silent it seemed you could almost hear the sky. Most of us rarely see such stars. They hide shrouded not only by cloud and haze but by the reflected glare of excessive lighting, even when we travel to countryside destinations. Hotels, motels, restaurants, and shopping centers have seen fit to bathe themselves in wattage far beyond the need for safety or utility. Having discovered that bright lights draw us like moths, service stations compete to bruise the night with stadium-strength floods. So it's reassuring to hear of a few moves to reclaim the sky that our great grandparents knew. In Las Vegas, New Mexico (not Nevada!), the Plaza Hotel has shielded all its outdoor lighting. (Notably, hotels that refuse to mute their external lighting are also refusing to lower their own utility bills and, thereby, our room rates.) Yellowstone National Park is starting to replace the upward-leaking lights around Old Faithful and other major sites. And in June 2003, in that tourism mega-center, Orlando, Florida, the county board imposed light-pollution regulations on new commercial facilities.
