In episode 1, we focus on the nature of the night. How and why is it getting dark? What is darkness and where is it particularly dark? In some places the night is like an ocean of lights: for example in the country, where you have a clear view of the sky and the stars without artificial light. Not to mention northern lights, which can be observed particularly well in the winter months. If the night is so "colourful", where does our fear of it come from?
