Present measured data of nightscape brightness back to the citizens.

Organize meetings to compare methods to measure sky brightness.

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

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

TESS photometer network to study night brightness around the Macaronesia area.

Virtual representation of Cities lighting using Sim city and Cities Skylines + low-cost probe (balloon) to take pictures of cities at night.

Thanks to the aliance with Kananga we are setting up in Southern Africa 6 fixed TESS-W stations and quantifying the sky darkness of remote locations with a portable TESS-W unit.

Efectos de la contaminación lumínica en niños

This study aims to measure the impact of light pollution on the performance of different brain functions in children.

Research on the evaluation of sleep and circadian health, especially in relation to the abuse of the body’s exposure to artificial light.

Through the Globe at Night APP, citizens can help raise awareness of the adverse effects of light pollution and measure the extent of these effects in five simple steps.

Citizens will understand the extent of the effects of light pollution on their lives and the environment through two disciplines that are very attractive to the general public: Astrophotography and smartphones.

Initiative to assess the level of light pollution in different areas of Italy and to raise awareness of the problem of light pollution.


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.

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”.

Europa iluminada

A platform that provides information on nightlight in relation to ecology, chronobiology, health, sleep patterns and society, as well as current research on light pollution.

Cielo estrellado

Citizens will understand the extent of the effects of light pollution on their lives and the environment through two disciplines that are very attractive to the general public: Astrophotography and smartphones.

This initiative aims to raise public awareness about light pollution through education. The aim is to train primary school teachers through collaboration with university professors.


Find the most crazy images of inefficient outdoor lighting! Inefficient use of lighting results in a waste of energy and is a threat for the environment. Help us identify the sites where light is installed in ridiculous ways (only in german).

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


Development of citizen data science experiences based on workshops to receive training on collection, analysis and visualization of light pollution data.

Study of facades luminance with architectural students. Best lighting in facades guide.


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

Study and characterization of nocturnal sky as seen from parks and natural scenarios such as Apuseni.

Locate, visit and place photometers in the darkest places in Europe (Scandinavia, Scotland, Ukraine and Russia).

The INTERREG project “Light Pollution – Common Process” deals with the problem of light pollution and the conservation of the “dark sky”.

Miradores estelares

The project seeks to get citizens to look at the sky again and to awaken their interest in astronomy.

Although the tourist attraction to the Mediterranean coast has made light pollution a serious environmental problem, there are still dark places where you can observe skies free of light pollution.


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

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

Create the change you want to see.

Here you can find guidelines for best practice and statements how to fight light pollution.

The project consists of promoting an autonomous legislative initiative in Madrid to improve night-time lighting.
