Winter stars and light pollution

Référence de la vidéo 11939508
Composite clip showing how light pollution obscures the winter stars of the Northern Hemisphere. As the camera tilts up, it is revealed how light pollution obscures the view of the stars. The clip is a composite of three images: the horizon view was taken from the Roque de los Muchachos observatory on La Palma, Canary Islands, with a 600 second exposure, the middle view was taken in the country with a 180s exposure, and the zenith view was taken from a city with a ten second exposure. The dramatic effect of light pollution is clearly seen: even close to the horizon, from the mountains the night sky is very dark and countless stars are seen. In the city sky, the lights hide many of the stars, and even at the zenith very few are visible through the reflected glow. Even Capella, the sixth brightest star in the sky, is barely seen at centre. Images taken from Germany, looking south.
