Discover the Night

International
Dark Sky Week 2021

Discover the Night
April 5–12

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.

“The universe is full of magical things patiently waiting for our wits to grow sharper.” —Eden Phillpotts

Taking advantage of the clear skies and low humidity recently. Here is the Milky Way rising over the red shack on Grass Island last night. Jupiter and Saturn are also visible just about the shack’s roof. 

For this shot, I used a Samyang 14mm lens to capture the shack and the breadth of the Milky Way arch. As anyone who has used an ultra wide angle lens knows, it adds a significant amount of distortion to the image. Closer objects are distorted much more than distant objects. This image require quite a bit of post processing to get the shack and the Milky Way looking correct, as each was distorted differently by the lens.

Schönheit der Nacht 

Dieses Foto entstand letztes Monat im Rahmen meiner Forschungsarbeit zum Thema Lichtverschmutzung. Es stand dabei tatsächlich mal nicht das Fotografieren der Schönheit des Nachthimmels im Vordergrund. Darum auch kein entsprechend geplantes Setting, kein spezifisch ausgerichtetes Equipment, und "nur" ganz einfache Fotos. Und doch ist am Rande ein solch schönes Bild entstanden, weil sich die Schönheit der Nacht immer durchsetzen wird, wenn wir sie denn lassen!

Beauty of the night 

This photo was taken last month as part of my research on light pollution. That night, the focus was not on photographing the beauty of the night sky. There was no appropriately planned setting, no specifically geared equipment, just a few "simple fotos". And yet such a beautiful picture "created itself", because the beauty of the night will always prevail if we let it!

Sunset over a field of smiling sunflowers. I came here just a week ago, and the flowers had not bloomed yet. What a difference one week makes! I was hoping the clouds from earlier in the day would stick around for an interesting sunset but they decided to bugger off. Oh well, at least I have a full field of smiling sunflowers.

A walk to Galactic Point. 

Finally, a clear and crisp night with minimal haze. The Milky Way was on fine display last night, as seen from Webster Point. To sit on this sea wall with feet dangling, while waves splash your toes and the Milky Way arcs overhead in breathtaking beauty, is one of the simple joys of living on the coast. To quote Calvin (from Calvin and Hobbes), “If people sat outside and looked at the stars each night, I bet they’d live a lot differently.”

“Twilight drops her curtain down, and anchors it on a star.”

Lately I’ve been thinking about the people who come into my life. They say everyone you meet is meant to teach you something about yourself. I suppose sometimes it’s meant to push you out of your comfort zone, expand your boundaries, and find growth you didn’t know was possible. And other times, perhaps it’s to help you understand where your own boundaries are, test your resilience, and how well you are anchored to your own center to weather out the storm that just crossed your path.

Eine andere Art sich zu vergegenwärtigen: wir alle sind aus Sternenstaub 😉

... und zum Beispiel unsere Zähne aus Kalcium, Phosphor und Sauerstoff, die in der Hitze von lange vergangenen Supernovae entstanden sind! (M. Westmoquette, Mindful Thoughts for Stargazers - Buchtipp!!)

🌌 Diese Verbindung zum Universum können wir sichtbar erleben, jedes Mal wenn wir in den Nachthimmel und seine Tiefen blicken - und uns diese nicht mit künstlichem Licht bei Nacht versperren!

____________________________

Another way to say; we are all made of stardust 😉

 ... and e.g. our teeth made of calcium, phosphor and oxygen, formed in the heat of past supernovae! (M. Westmoquette, Mindful thoughts for stargazers - highly recommended!!) 

We can experience this connection to the universe each time we look into the night sky and its depths - and not obstruct this with artificial light at night!
