Check out what we are doing

Broadcasting of astronomical events for engaging newcomers and creating awareness of the light pollution problem.

European sky protection

Collecting citizen signatures from at least one quarter of the EU member states.

Lighting Quality Label

Quality label recognizing the sky protection compliance of companies, NGOs, villages or any kind of institution.

The beauty and the beast

Detect the beauties and the beasts of lampposts! With your help we will create a map of inefficient lighting systems.

Inefficient Inside Lighting

Identify inefficient outdoor commercial lighting! Inefficient use of commercial lighting results in a waste of energy.

Monitoring light pollution with low cost photometers designed by astronomers to study its evolution.

Cities at Night keeps track of World light pollution with images taken by astronauts onboard the ISS.

Empower Citizen Actions

Create the change you want to see.

Organizes Light Pollution Collective Awareness Activities.

Monitoring Light Pollution from any location by using mobile phones.

Present measured data of nightscape brightness back to the citizens.

Organize meetings to compare methods to measure sky brightness.

Find and characterize places where people could go to enjoy dark and starry skies.

Citizen-science campaign to raise LP awareness by gathering night sky brightness measures

With this kit young students can explore the concepts of quality lighting through six activities.

Raising awareness on the issue of LP, collecting quantitative data and promoting participatory processes.

Collect qualitative data from citizens using web and mobile apps aim to discover territorial controversies.


TESS photometer network to study night brightness around the Macaronesia area

Dark sky meter

Use your iphone to measure night sky brightness with this app.

Education on LP. Portugal and Galicia

Photometers to be installed in 15 late year primary schools and 15 secondary schools to study light pollution on “coastal regions” vs “inner land regions”
