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.

Pathway to the stars. 

I run past this spot on Seaview frequently, and I’ve always wanted to capture the Milky Way from here. Timing it with a clear night with minimal wind, no fog, no rain, and no moon was the challenge. This morning at 3am was the magical moment when it all lined up. Some things are worth getting up for. 

Happy Mother’s Day!

This is the view from a beach just out of my hometown. Thankfully we have a lot of beautiful places to spend your time with friends or family. The fact that we're close to Athens has been a very helpful parameter for the village, although this isn't the best part if you're a stargazer and you want to capture the night sky. In this image, I've captured the light pollution, caused by the city lights of Athens (56 km straight away) and the near cities, reflected on these high clouds. Light pollution is as harmful to humans' as to animals' health.

There are few things in life as calming to the soul as reconnecting with Mother Nature. Sometimes when I get into those familiar destructive thought patterns, a long walk in the woods or settling in behind the camera lens works wonders. It is then that (borrowing the words of Sir Paul), Mother Nature comes to me, whispering words of wisdom, “Let it be.”

This is sunset last night from Seaview Bridge.

Werde Citizen Scientist und untersuche ganz ohne Hilfsmittel die Lichtverschmutzung an deinem Nachthimmel!

Satelliten messen die globale Lichtverschmutzung, doch das können sie nicht alleine. Einschlägige Programme wurden eingestellt, kurzwelliges blaues Licht - welches vermehrt bei LED zum Einsatz kommt - erreicht die Satelliten nicht... An dieser Stelle sind wir gefragt! Das Citizen Science Programm "Globe at Night" sammelt seit 14 Jahren Beobachtungsdaten von Citizen Scientists, also von Menschen wie du und ich. 

200.000 Daten aus über 180 Ländern wurden so bereits gesammelt und bilden einen unverzichtbaren Teil in Erhebung von und Forschung zu Lichtverschmutzung.

Jedes Monat rund um den Neumond sind wir alle eingeladen rauszugehen und nach einem bestimmten Sternbild Ausschau zu halten. Welches es ist und wann wir beobachten können, erfahren wir auf der Homepage von Globe at Night (Link ⬇️)

Hast du das Sternbild gefunden, kannst du per App oder Webversion deine Beobachtungsdaten eintragen. Also unter welchen Bedingungen du beobachten und wie gut du das gesuchte Sternbild erkennen konntest.

⚠️Gleich Lust bekommen?⚠️
Im Mai wird das Sternbild des Bärenhüters, Bootes beobachtet (Bild ⬆️, Quelle Freeware Stellarium). In Mitteleuropa steht dieser  aktuell um 22 Uhr im Osten. Sein hellster Stern, Arktur, ist leicht zu finden. Orientieren kannst du dich auch am großen Wagen/großen Bären, der momentan hochkant am Himmel steht und mit seiner Deichsel/seinem Schwanz direkt auf den Bärenhüter zeigt.

Eine kurze Anleitung und den Link zur Eingabemaske für deine Beobachtungen findest du hier: https://www.globeatnight.org/6-steps.php

Solltet ihr dabei sein, lasst mich doch gerne hier eure Erfahrung wissen. Also, clear skies uns allen!🌠

“As with any journey, it doesn’t matter where you’re going. It’s who you have beside you.” —Anonymous

For tbt, a look at this couple kayaking out to the sunset over Tuxis Island. The sun was caught momentarily in the tops of the tree branches, and I imagined the pair racing out to rescue it. Life is a journey. Every day. Make the most of it. And Happy Thursday!
