/skī’glō’/
noun
brightness of the night sky in a built-up area as a result of light pollution.

After a grueling three-year journey of over 150,000 miles traveled and 3,000,000 pictures taken, renowned timelapse filmmakers Harun Mehmedinovic and Gavin Heffernan are proud to introduce SKYGLOW; a hardcover photo book and timelapse video series exploring North America’s remaining magnificent night skies and the grave threat of light pollution to our fragile environment. SKYGLOW explores the history and mythology of celestial observation, the proliferation of electrical outdoor lighting that spurred the rise of the phenomena known as "skyglow,” and the Dark Sky Movement that's fighting to reclaim the night skies. Featured by rock legends The Rolling Stones and Pink Floyd's Roger Waters, BBC Earth, National Geographic, Time, National Park Service, and over 1000 media outlets, SKYGLOW images and videos have been seen by over 200 million people. 

Just how Carl Sagan and Stephen Hawking brought deeper understanding of the cosmos, Heffernan and Mehmedinovic are raising awareness about the damage caused by ever increasing light pollution. Their magical timelapse photography just might do the trick.
— Ken Kaplan, INTEL IQ

SKYGLOW, a 192 page full color 12x9 Hardcover Astrophotography book and Timelapse Blu-Ray, tackles the most light polluted cities and pristine Dark-Sky preserves of North America. A blend of images, stories, essays, anecdotal captions and astro-timelapse videos, SKYGLOW explores the history and importance of celestial observation on humans, the proliferation of electrical outdoor lighting spurring the rise of the phenomena known as Light Pollution, and the Dark-Sky Movement which is fighting back to reclaim the pristine night skies the Earth had enjoyed for billions of years. Produced in collaboration with International Dark-Sky Association, and available in Regular and Limited Edition signed by the authors.

ARTIFICIAL DAY


ARTIFICIAL DAY

 

Our fantastic civilization has fallen out of touch with many aspects of nature, and with none more completely than with night. Primitive folk, gathered at a cave mouth round a fire, do not fear night; they fear, rather, the energies and creatures to whom night gives power; we of the age of the machines, having delivered ourselves of nocturnal enemies, now have a dislike of night itself. With lights and ever more lights, we drive the holiness and beauty of night back to the forests and the sea; the little villages, the crossroads. Are modern folk, perhaps, afraid of night? Do they fear that vast serenity, the mystery of infinite space, the austerity of stars? Having made themselves at home in a civilization obsessed with power, which explains its whole world in terms of energy, do they fear at night for their dull acquiescence and the pattern of their beliefs? Be the answer what it will, today’s civilization is full of people who have not the slightest notion of the character or the poetry of night, who have never even seen night. Yet to live thus, to know only artificial night, is as absurd as to know only artificial day.
― Henry Beston, The Outermost House, 1928

LIGHT POLLUTION

Light Pollution, also known as Skyglow, may not appear to be the most urgent problem facing the planet, but it may be the most indicative of humanity's growing separation from nature. Light pollution impacts health of humans and animals, especially nocturnal wildlife, and disrupts ecosystems. It also leads to waste of large percentages of energy and the disruption of astronomical research, among a long list of impacts. Light pollution runs counter to necessity for a green, sustainable future.

However, this problem is one an average citizen can do something about, as Verlyn Klinkenborg states in his article on Light Pollution"Of all the pollution we face, light pollution is perhaps the most easily remedied. Simple changes in lighting design and installation yield immediate changes in the amount of light spilled into the atmosphere and, often, immediate energy savings."

Los Angeles, California is one of the most light polluted cities in the world.

Los Angeles, California is one of the most light polluted cities in the world.

IMPACT ON ANIMALS & PLANT LIFE

Fireflies, which used to cover most of lower North America during the months of May through July, are one of the animal species devastated by light pollution. Relying on complete darkness to perform their mating rituals, fireflies have retreated into the last remaining dark areas of their habitat, decreasing their overall population by as much as 90 percent, according to some estimates.

Birds that migrate or hunt at night navigate by moonlight and starlight. Artificial light can cause them to wander off course, migrate too early or too late, and miss Ideal climate conditions for nesting, foraging, and other behaviors. Every year, millions of birds die colliding with needlessly illuminated structures.

IMPACT ON HUMANS

Artificial light emanating from house lights, electronics, and other sources suppresses melatonin, an antioxidant that induces sleep, boosts the immune system, lowers cholesterol, and helps the functioning of the thyroid, pancreas, adrenal glands, and various other parts of the body. The full impact of nocturnal light on the health of human beings is not yet known as many studies are still to be conducted. Research to date suggests that artificial light’s disruption of circadian rhythm is one of the causes of obesity, depression, insomnia, diabetes, and breast cancer.

Even fish, such as salmon, are susceptible to having their mating processes disturbed by artificial light pollution. Sea turtles often mistake city lights for moonlight shimmering in the ocean.

Trees have been shown to bloom too early due to artificial light. Later-budding trees such as ash trees are most affected by light pollution, which in turn impacts all the animal life that depends on those trees’ natural bloom cycle.

And these luminaries radiate their light over much of the electromagnetic spectrum and scatter much farther through the atmosphere, even when shielded. 

Cities need to install filters that can remove the LEDs’ blue wavelengths, as well as shields that better aim the lights down. Those fixes are costly. But there are some potential positives to LEDs that aren’t yet widely utilized.

The latest bulbs are tunable, which means streetlights might someday make use of warmer, more natural amber colors. Indoor lights and electronic displays can change their hues throughout the day, keeping you more attentive when you need to be, but dialing back the blue as the sun sets.

L.E.D. REVOLUTION

LEDs (light-emitting diodes) compound the light pollution problem. Most city-dwellers are familiar with the traditional yellow hues of low- and high-pressure sodium-vapor streetlamps, which shine in a narrow range. But broad-spectrum LEDs are the future. The brighter and more efficient streetlights can save cities millions of dollars on their power bills, so municipalities big and small are starting to convert.

The most common bulbs are blue with a special coating that makes them appear white to human eyes. This also causes these LEDs to peak in the short wavelengths astronomers commonly use to observe the night sky.

BORTLE SCALE

The Bortle Scale is a nine-level numeric measure of the night sky’s brightness in a particular location. It quantifies the astronomical visibility of celestial objects and the interference caused by light pollution. John E. Bortle created the scale and published it in the February 2001 edition of Sky & Telescope magazine to help amateur astronomers evaluate and compare the darkness of observing sites. The scale ranges from Class 1, the darkest skies available on Earth, to Class 9, daylight-like inner city skies.

With the estimated light pollution growth of 6% a year, all of developed world may lose its dark skies by the end of the 21st century.

DAWN OF LIGHT


DAWN OF LIGHT
Before the time of artificial light, the world only knew of lightning bolts flashing in thunderstorms, waxing and waning moons, random fires in the forest. For billions of years prior to the arrival of humans, life on earth came to be in perfect harmony with daylight and darkness, each equally important to its existence. Early humans readily observed the darkest of night skies, where the collective light of billions of stars in our Milky Way was so intense it would cast shadows on new moon nights. Night skies inspired many questions about our place in the universe, giving birth to both religion and science, two ways to offer answers to what the Sioux called The Great Mystery. While one part of the human psyche drew inspiration from the night sky, the other always lamented the absence of the sun.

Hawai'i volcanoes give us a glimpse into how the earliest days of the Earth may have looked with pristine night skies over endless volcanic activity 

The first presence of natural light pollution on Earth proved to be essential to its creation. Endless volcanic activity--a mixture of lava, ash, and gas that escapes from a magma chamber deep below the surface--has been shaping the planet from the very beginning. This phenomenon continues in Hawai’i, Earth’s most volcanically active spot, where new land is created on a daily basis.

For billions of years, lightning was the brightest light in the night sky. Each flash lasted only a millisecond, providing brief but blinding illuminations, as seen here at the Grand Canyon, where thunderbolts often strike near the edges of the rim in spectacular fashion.

Two other rare, but nonetheless present forms of natural light pollution, were meteors burning in the earth’s atmosphere, as well as Aurora Borealis (Northern Lights).

The night skies prior to artificial light pollution were so pristine, during the darkest nights, in the new moon portion of the lunar cycle, when there was minimal or non-existent reflection of sunlight into the night sky atmosphere, the Milky Way would get so bright it would cast shadows and illuminate the landscape.

For humans, unlike other animal life, night became a fertile source of both fascination and dread of the unknown. Night sky, the source of endless unsolved mysteries, became the inspiration for some of the oldest known stories and myths.

Devils Tower, Wyoming

Devils Tower, Wyoming

For many centuries, indigenous tribes such as the Blackfeet could witness pure dark skies each night from their homes, developing rich mythologies that stemmed from their observations of the heavens. Stories told and songs performed around campfires gave forms to the sights above.

One day, seven little girls were playing away from their village. Suddenly, large black bears chased after them. Knowing they couldn’t escape, the girls jumped on a low rock and began to pray: Rock take pity on us, please save us! The rock began to grow upwards, pushing the girls higher and higher. The bears jumped to reach the girls, but only scratched the rock, broke their claws, and fell on the ground. The rock rose higher and higher, all the way to the sky, and the girls became the constellation Pleiades, The Seven Sisters.

Bodie, California, is a ghost town frozen in time, giving us a glimpse of Gold Rush night skies.               

The gold and silver mines of California were the last stops on the long journey west. The Gold Rush created the permanent entrenchment of white settlers
in the American West, and new technologies that made it easier to travel to and live in those harsh, mountainous climates began to arise.

Electricity, followed by electric light, arrived in California in the late-1880s, along with steam engine train technologies, and soon thereafter the growth of the oil industry and automobiles.

Just a few hundred years after Native American archaeoastronomy sites covered the land, Manifest Destiny had led to the near-destruction of many Native American cultures. All that remains now are Americana throwbacks
to ancient European archaeoastronomy sites such as Carhenge in Nebraska.

 

The age of dark skies, with us from the very beginning of humanity, has come to an abrupt end.

DARK-SKY MOVEMENT


DARK-SKY MOVEMENT
From the very earliest days of electric street lighting, astronomers were the first humans to notice the effects of skyglow. Observational astronomy, disrupted by artificial light, began to move farther and farther away from cities, chasing ever-receding pristine night skies. When it became clear that simply distancing themselves from expanding cities would not stop the inevitable destruction of all dark skies, both professional and amateur astronomers began to fight back.

Flagstaff, Arizona, First International Dark-Sky City

Flagstaff, Arizona, First International Dark-Sky City

 In 1958, the small mountain town of Flagstaff, Arizona, became the first municipality in history to enact a light pollution control ordinance. Flagstaff is home to the Lowell Observatory, where Pluto was discovered, the early Martian surface research was conducted, and the first evidence of Dark Matter was registered. Flagstaff’s Northern Arizona University Astronomic Research Observatory was first to conduct an infrared observation of the sky from Earth’s surface.

Flagstaff’s light control ordinance prohibited “the use of commercial searchlights within the city limits.” Punishments for violating the ordinance included “imprisonment in the city jail not to exceed 90 days.”

Protection of the night sky continued for decades as Flagstaff grew in population. Coconino County, where Flagstaff is located, enacted a lighting code in 1973, covering the second-largest county in the United States. In 1981, the county took it a step further, banning all billboards and the accompanying lighting.

Finally, in recognition of its pioneering role in protecting the night sky, Flagstaff was designated the World’s First International Dark-Sky Community by the International Dark-Sky Association in 2001.

Since then, over a dozen other cities enacted a light pollution ordinance, including Sedona, Arizona and Borrego Springs, California.

Today, the National Park Service protects some of the most pristine dark sky areas in the country. The National Park Service Natural Sounds and Night Skies Division measures light pollution in parks around the country and develops strategies to curb the impacts of skyglow.

However, despite National Park efforts to preserve nature for the enjoyment of the people, the use of artificial light both within and outside the boundaries of the National Parks threatens the quality of night skies.

Joshua Tree is one of such parks affected by the light from neighboring Los Angeles and Palm Springs, while being stuck between Los Angeles area and Las Vegas keeps the even the remotest parts of the Mojave National Preserve from maintaining clear night skies.

Meanwhile, much of New Mexico’s White Sands National Monument suffers from light pollution coming from nearby cities Alamogordo and Las Cruces.

In Yellowstone National Park, as in other sanctuaries, the prevalence of light around building structures makes it impossible to achieve perfect dark skies in all areas of the park. 

Even in the more detached parks, such as Death Valley, car lights add to artificial light intruding on the quality of darkness, while a combination of cars and light pollution from surrounding towns significantly impacts night sky quality over every single stretch of the 469-mile Blue Ridge Parkway.

In Shenandoah National Park, only the occasional passing clouds block enough light from the surrounding cities to offer visitors a decent view of the heavens. With an estimated light pollution growth at 6 percent a year, National Parks, along with all of the developed world, may lose their dark skies by the end of the 21st Century.

Harun Mehmedinovic

Harun took up photography as a hobby during his road trips across America. Years later, his portrait project Bloodhoney* became one of the most successful Kickstarter photography campaigns of all time. 

He is a regular contributor to BBC Earth, and has contributed photographs and videos to Vogue Italia, National Geographic, Astronomy Magazine, BBC Travel, Discovery Science, and Blindfold Magazine. Harun’s photography work has been featured by various media outlets, including Time, Wired, NPR, Los Angeles Times, LA Weekly, Vice, and Washington Post. It has also been the subject of a TEDx Talk. His videos have been featured at various events, most notably by The Rolling Stones on their ZIP CODE tour and the upcoming 2016/2017 tour; Pink Floyd’s Roger Waters’ 2016 Tour and Desert Trip Indio Concert; Trance duo Cosmic Gate’s am2pm music video; and National Park Service’s “100 Years” centennial video; among others.

Harun’s photograph of the cloud-inverted Grand Canyon was listed among the 2015 best travel photos of the year by National Geographic, and in 2016, he was on the BBC Earth Instagram team that won a Webby Award for “Best Photography and Graphics.”

Prior to his venture into photography, Harun’s film In the Name of the Son premiered at Telluride Film Festival and won over thirty international awards, including Shanghai, Savannah, and Cleveland film festivals. It was the first live action short film to receive an exclusive screening for the members of United States Congress on Capitol Hill.

Recently, Harun began work as a cinematographer on Ice on Fire, a Leonardo DiCaprio-produced documentary for HBO.

Founded in 1988, the International Dark-Sky Association (IDA) is dedicated to protecting the nighttime environment and our heritage of dark skies through quality outdoor lighting. Light pollution is an environmental threat that harms our planet and robs us of the opportunity to experience the wonder of a natural night sky. Since its founding, IDA has taken the lead in identifying and publicizing the adverse impacts of artificial lighting on wildlife, the climate and health.

Outdoor lighting in the U.S. alone uses some 120 terawatt hours of energy per year. IDA estimates that at least 30 percent of light generated is wasted due to poor design, releasing 21 million tons of CO2 into the air every year.
IDA advances light pollution abatement by working with manufacturers, planners, legislators and citizens to provide and implement lighting that is energy efficient, cost effective and dark-sky friendly.

IDA’s conservation program, International Dark Sky Places, was created in 2001 to recognize excellent stewardship of the night sky. Designations are based on implementation of stringent lighting management plans, outreach programs to educate the public about night sky protection, and provide access to the night environment provided through stargazing parties and events. Since 2001, IDA has certified more than 70 such places in 15 countries across six continents.

The good news is that light pollution, unlike many other forms of pollution, is reversible and each one of us can make a significant difference! However, being aware that light pollution is a problem is not enough; spe-cific actions can be taken to limit incorrect, excessive, or unnecessary use of light. You can start by minimiz-ing the light emitted into the night sky from your own home and community by following a few simple steps: 

  • Use fully shielded, dark-sky-friendly fixtures. That means lights that shine down, not up into the sky.
  • Install timers, motion sensors and dimmer switch-es, and turn off lights when not in use.
  • Use long-wavelength lights with a red or yellow tint to minimize negative health effects and reduce impact on the night sky.
  • Keep your blinds closed.
  • Use right amount of light

Educate your family and friends on matters related to light pollution. Many people are unaware about the negative impacts of artificial light at night to human health, wildlife and the environment. By being an ambassador and explaining the issues to others you will help bring awareness to this growing problem and inspire more people to take the necessary steps to protect our natural night sky.  For more information, please visit: www.darksky.org
