On Friday, 21 May, CERN took part in the general switch-off of public lighting for the event La nuit est belle!

La nuit est belle! aims to raise public awareness about the impact of light pollution caused by artificial lighting. This second edition was dedicated to the protection of nocturnal biodiversity.

Despite the cancellation of some of the activities due to the rain, 178 municipalities in Greater Geneva actively participated in the event by not turning on their streetlights. Shops, companies and private individuals also joined the movement, as well as more than 100 municipalities beyond Greater Geneva.
