Discover the Night

International
Dark Sky Week 2022

Discover the Night
April 22–30

It may seem harmless, but light pollution has far-reaching consequences that are harmful to all living things. Effective outdoor lighting reduces light pollution, leading to a better quality of life for all. The dark sky movement is working to bring better lighting to communities around the world so that all life can thrive.

Join us this International Dark Sky Week to learn more about the movement, and discover the night where you live.

Cityscape to the Milky Way

A lot of the outdoor lighting used at night is inefficient, overly bright, poorly targeted, improperly shielded, and in many cases, completely unnecessary. This light and the electricity used to create it are being wasted because it spills into the sky rather than being focused on the objects and areas that people need illuminated.

Harmful effects on wildlife

Light pollution harms mammals, birds, amphibians, insects, and reptiles. It can decrease reproduction, disrupt migration, increase predation, and more.

Bad, better, best

Use outdoor lighting responsibly by only using it where it’s needed, when it’s needed, in the amount required, and no more. Make sure to use the lowest light level required, limit the amount of shorter wavelength (blue-violet) light, utilize controls (such as timers or motion sensors), and use shielding to target the light, so it does not spill beyond where it is needed.

Effective outdoor lighting

A wide variety of dark-sky-friendly lighting fixtures are vailable from manufacturers.

What is Light Pollution?

Any artificial light that is not needed is a pollutant that has serious and harmful consequences.

Light pollution can:

  • disrupt wildlife
  • impact human health
  • waste money and energy
  • contribute to climate change
  • block our view of the universe

Light pollution is increasing at 2x rate of population growth and 83% of the global population lives under a light-polluted sky.

About Us

IDA protects the night from light pollution

Artificial light at night has revolutionized the way we live and work outdoors, but it has come at a price. When used indiscriminately, outdoor lighting can disrupt wildlife, impact human health, waste money, and energy, contribute to climate change, and block our view of the universe. 

The International Dark-Sky Association promotes win-win solutions that allow people to appreciate dark, star-filled skies while enjoying the benefits of responsible outdoor lighting.

Our Vision

The night sky, filled with stars, is celebrated and protected around the world as a shared heritage benefiting all living things.

T'is the season... of grey skies, sleet, cold and dark. But of course also some natural and architectural beauty. Here's a view of Larvik harbor with its cranes and mounuments, plus the #ColorLine terminal. From this point you can sail across to Hirtshals in northern Denmark in just under four hours. The ship sailing between these two points is named Colorline_Superspeed for a reason.

Was ich einmal sehe, kann ich nicht mehr nicht sehen.

Jede/r von uns kann einen wichtigen Beitrag zur Reduktion von Lichtverschmutzung leisten. Was es dazu braucht? Bewusstsein und Wissen. Meine Beiträge wollen dieses Wissen und Bewusstsein vermitteln. Nie mit erhobenem Zeigefinger, denn das ist nicht meine Wahrheit. Dafür von Zeit zu Zeit mit Bildern der Nacht, die ihre Schönheit zeigen, das, was es zu erhalten und was es zu verlieren gibt.

🌟🌟🌟

What one sees once can no longer not be seen. 
Each of us can make an important contribution to reducing light pollution. What does it take? Awareness and knowledge. My contributions want to convey this knowledge and awareness. Never with a raised finger, because that is not my truth. Instead, from time to time with pictures of the night that show their beauty, what needs to be preserved and what could be lost.

On this last day of 🌀 #NativeAmericanHeritageMonth, learn about aztecruinsnm in New Mexico ➡️ https://www.nps.gov/azru/index.htm. Gazing into the night sky above an archeoastronomy site is a special experience. It connects past and present, allowing a view into the past which connects culture to cosmos.

Pueblo people describe this site as part of their migration journey. Today, you can follow their ancient passageways to a distant time. Explore a 900-year old ancestral Pueblo Great House of over 400 masonry rooms. Look up and see original timbers holding up the roof. Search for the fingerprints of ancient workers in the mortar. Listen for an echo of ritual drums in the reconstructed Great Kiva.

Some tips for stargazing in general:

🌟 Make a red flashlight. Use red paper or cellophane to cover a white flashlight. This will help you navigate at night without compromising your night vision!
🌟 Attend your local astronomy club's next public "star party." There you can find amateur astronomers sharing views through their telescopes.
🌟 Camp under the stars. What better way to experience the great outdoors than camping in a national park under a star-filled sky?
🌟 Find national parks that offer night sky programs, from telescope astronomy events to full moon walks with rangers

Last night we stayed in a tiny house in southern Utah. The sky is super dark in the area, so taking star photos is way easier. Hope to make it back soon!
