An exposure time of close to two hours has captured intense activity at Cosmiques refuge (3,613 m) in the Mont Blanc massif. The high altitude pure sky offers a beautiful tapestry of stars that enfold the Polar star, a sign of the rotational movement of the Earth. At this early time of night, 18 planes, 7 satellites and 5 meteors feature in the picture. Climber groups departed from Aiguille du Midi descend to the edge of the Cosmiques, illuminated by the refuge spotlight. On the terrace, observers are busy with telescopes and cameras in this beautiful starry night.
