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.

“If the stars should appear one night in a thousand years, how would men believe and adore; and preserve for many generations the remembrance of the city of God which had been shown! But every night come out these envoys of beauty, and light the universe with their admonishing smile.” – Ralph Waldo Emerson

I PIANETI AL TRAMONTO

Se in queste sere poco dopo il tramonto avete visto dei punti luminosi, stavate osservando sicuramente un pianeta! In particolare, in queste sere, in direzione Sud-Ovest, si possono osservare Giove, Saturno e un timido Mercurio, in procinto di tramontare. Questo fenomeno viene chiamato "Congiunzione". 

In astronomia una congiunzione si verifica quando due oggetti del sistema solare hanno la stessa ascensione retta o la stessa longitudine eclittica osservata dalla Terra. 
In questo caso Saturno e Mercurio si trovano alla stessa longitudine eclittica, mentre Luna e Giove fanno da contorno alla congiunzione.

Delighted to capture the Andromeda Galaxy along with the Double Cluster in Perseus and some Milky Way dust lanes.
Also caught the Triangulum Galaxy below Andromeda.
Five Galaxies in one photo, plus two star clusters 😁
Have a good day and clear skies.

Milky Way image I shot in 2020, thought I'd put some practice in whilst waiting on the first quarter moon phase to start. Might do a live moon streaming if things go right.

Interested in ✨ dark skies? Apply to be a Night Skies Assistant at carlsbadcavernsnps through the mosaicsinscience_nps Diversity Internship Program and keep an eye on our page for more exciting opportunities for youth and young adults!

The stunning 🔭 night sky of Carlsbad Caverns National Park draws visitors from around the world. But this resource is threatened by unshielded lights on rapidly expanding nearby oil and gas development. 

🧐 This internship will measure current sky brightness levels, document the growth of point source lights in the Permian Basin, create materials to help educate the public about the importance of the night sky, support the park’s International Dark Sky Park (IDSP) application, and help both the park and neighboring agencies make informed management decision about visual resource protection.

Apply by January 23rd ➡️ https://www.mosaicsinscience.org/job/night-skies-assistant/

Os dejo por aquí la foto de esta luna nueva en el CAAT. Se trata de una nebulosa oscura conocida como "The Helping Hand" o LDN 1355, ubicada en la constelación de Cassiopea. Esta hecha con tubo Ritchey Chertien 10" y son unas 17 horas de integración . Espero que os guste.
