Résumé
For over thirty years, Les Makes Astronomical Observatory in Reunion island, a French overseas department about 700 km East of Madagascar and part of the Mascarenes Archipelago, has been dedicated to outreach activities, school-designed pedagogical and remote research programs in general astronomy. After summarizing its historical achievements, we will present the recent projects developed for teachers, primary and secondary schools, and at the University level, with a particular emphasis on participatory sciences. We will discuss the OAE-supported Teacher Training Program (TTP22) and the associated pedagogical projects which have been carried out in relation with the preservation of the night sky, considered as a natural environment with an important cultural dimension, that needs to be preserved from the ever-growing light pollution. We will then discuss on how these starry-sky-based programs have the potential to increase the awareness among the participants regarding the light pollution issue and could open up to further interdisciplinary projects on the nocturnal environment. Future developments, especially within the recently-founded laboratory of citizen sciences LASCAR (LAboratoire de Sciences Citoyennes pour l’Académie et la Région Réunion), through the setting of research programs dedicated to secondary schools in order to exploit the on-site instruments data, will also be presented.
