Stars4all Foundation

The STARS4ALL foundation is a general-interest foundation, as a mechanism to provide sustainability to the main results obtained in the context of the H2020 EU project STARS4ALL, especially in relation to the production and maintenance of the TESS photometer network and the provision of open data from such network to researchers and civil society organisations. Furthermore, the STARS4ALL foundation organizes and participates often in outreach events to encourage the protection of night skies and provide information about light pollution and its negative effects.

Create a better place to live

Artificial light at night is associated with the sense of security, wealth and modernity. Hence, light pollution is widely spreading after the onset of darkness.

STARS4ALL is a European project raising awareness about the negative effects of artificial light on human wellbeing, biodiversity, visibility of stars, safety and energy waste.


Putting light back in the spotlight


Light-pollution and its consequences are still poorly understood. When clear information is gathered, changes can happen.
