The IAU100 Global Project Dark Skies for All aims to raise awareness for the preservation of quiet and dark skies and to claim the right for future generations to continue to access our true night skies. The project has now opened the registration for becoming one of its ambassadors for the IAU100 to protect dark skies.


The IAU100 Dark Skies Ambassadors is a program that invites keen enthusiasts worldwide to be dark sky advocates and to spread the word of the concern of light pollution. Dark Skies Ambassadors help organise and disseminate events through their networks, while encouraging others to participate. This program also stimulates a peer-supporting environment and provides visibility of events. There are three levels of participation for individuals or organizations (based on previous experience) who are interested in promoting dark sky protection. We encourage individuals and organisations to sign up as ambassadors and to organize activities. For example, ambassadors can organize actions around the UNESCO International Day of Light on 16 May 2019, an international initiative celebrating the vital role of light and related technologies in science, culture and art, education and sustainable development.


We are also inviting educators and dark skies advocates to contribute and share their dark skies resources with the resources portal. Please also note that the deadline for the application to receive the “Turn on the Night” Dark Skies kit is 1 March 2019. The application can be found here.
