| Description: | An evocative picture of the Dwingeloo church spire against the dying light of the nearest star. Because of the long distance that the light from the setting Sun has travelled through the atmosphere, two things look different: The Sun appears oval because of refraction, and it appears red because its blue light is scattered much more effectively than its red light. The scattered light is what makes the sky look blue in the daytime.
The unusual shape of the church spire is a reminder of the fact that the Ottoman invasion of Europe was finally stopped before the walls of Dwingeloo, exactly 450 years ago. |
