Die dunkle Seite des Lichts

In the planetarium, we can clearly admire the beautiful starry sky, the "night" is deep black - just like in the great outdoors, far away from cities and disturbing light sources. The naturally dark starry sky was also a source of inspiration for our ancestors for thousands of years. Isn't it strange that today we have to travel to remote areas to see it in all its glory?

Artificial light sources have made the night sky very bright, especially in cities - the stars are barely visible, the Milky Way usually not at all. However, this light pollution not only obscures the view of the stars, but can also irritate and negatively affect plants, animals and people.

The many artificial light sources that radiate upwards and are reflected and dispersed in the atmospheric layers can even be seen from space.

In "The Dark Side of Light", you can find out why and how we humans disturb our environment through light pollution, what effects it has on us and on nature as a whole, and what each of us can do about it.
