CERN supported the “La nuit est belle” initiative, which took place during the night of 26-27 September. With more than 149 municipalities taking part on both sides of the French-Swiss border, the Organization decided to switch off a large proportion of its own lights.

The initiative aimed to raise awareness among local residents in the Greater Geneva area about the harmful effects of light pollution, energy saving and the protection of nocturnal biodiversity. Despite the cloudy intervals, many stars were still visible and the conditions for star-gazing were ideal.
