We live in a world of constant wakefulness. Production, consumption, and communication never cease — not even at night. With the invention of electric light, capitalism emerged. Cities, households, and natural environments are continuously illuminated, causing the pure, dark night sky to gradually fade.

This Glossary of the night is a plea for imagination, dreaming, and the sensuality that the night reveals to us. It calls for an appreciation of darkness and raises awareness of light pollution. Based on interviews with scientists and conversations with members of the Observatory, the book combines factual information with poetic reflections on the night. A special fluorescent print appears to glow from the pages, emphasizing the play of light and darkness.
