Dark and Quiet Skies

An IAU Global Outreach Project



The Dark and Quiet Skies project raises awareness about the need to preserve dark and quiet skies. Through the project, people can learn about the importance of dark skies for human culture, heritage, and health as well as the use of dark and quiet skies for astronomy research.


The IAU Office for Astronomy Outreach (IAU OAO) conducts this project in collaboration with the IAU Commission B7 and various partners.



Join us on 31 May 2022 at 14:00 UTC for the One Sky, One Home: A Seminar for the Protection of Dark and Quiet Skies. This online event will bring together astronomers, outreach professionals, artists, curators, and practitioners to share their connection to the dark sky, its importance to the world’s cultures and to our global ecosystem. We invite the broader astronomy community and all citizens of Earth to engage the problem head-on and discover solutions together. Register via Eventbrite.

Celebrate the Dark Skies Contest

Imagine you've stumbled into an open clearing. It's well past sunset, and the Moon is new - what do you see when you look up at the sky? Are there city lights? Stars? Can you spot any planets? The Milky Way? What do these views mean to you?


Using any medium you'd like, create a piece of art that describes what dark skies mean to you and your community. Submit your artwork for a chance to win one of three BRESSER NANO AR-70/700 AZ Telescopes, courtesy of Sterren Schitteren Voor Iedereen (Stars Shine For Everyone - SSVI) and Bresser, and more: you will be invited to present your art during the One Sky, One Home: A Seminar for the Protection of Dark and Quiet Skies, on 31 May 2022.
