“Féérie d’une nuit” is an event organised by an association since 2003 in order to discover the universe. Every year, Signal de Bougy is turned into a Big observatory and the star party gathers many astronaut lovers.
In short, you will be able to attend conferences (in French), launch a water rocket, get inside a space shuttle simulator, observe the sky (day and night) with scientific tools, attend constellations workshops in 3D, etc.

Every activity is free of charge and even if the weather is not good, the event still takes place.

Saturday August 20th from 2pm to 2am
Parc Pré vert, 1172 Aubonne
Free entrance
