Beneath the celestial vault of Nancray, the museum will be offering its visitors an unusual experience. At sunset, on the upper part of the site, the Association Astronomique de Franche-Comté (Franche-Comté Astronomical Association) will be setting up a dozen telescopes and offering curious visitors the chance to observe the stars.
It's an opportunity to meet and listen to these enthusiasts, and to learn a little more about the cosmos. Those who wish will be invited to spend the night in a tent or under the stars in the museum grounds, where breakfast will be served early in the morning.
