Ustaoset

Ustaoset is a small place along ‘Bergensbanen’, a railroad between Bergen and Oslo in the mountains of Norway. The station is 991 meters above sea level. Of course you can get there by car as well, taking RV7 across ‘Hardangervidda’. At Ustaoset there is a cluster of approx. 900 cabins, hotels and lodges. You will find great hiking possibilities in the summer, and in the winter you can enjoy cross country skiing. If you go 10 minutes by car, you find one of Norway’s most popular ski resorts, Geilo. During the winter, they have shuttle busses to trasport ski-tourists between Ustaoset and Geilo.

For some reason, when watching the image gallery with the Photo Carousel, the photos are not as sharp as when watched in full size.

Colours of the Sky

It is kind of a clichè – I know, pictures of the sunset. Still, I think most people find them beautiful.  But why does the sky turn orange?

Molecules and small particles in the atmosphere change the direction of light rays, causing them to scatter, which affects the colour of the light. The wavelength of the light, and the size and  amount of molecules the light has to pass through, determines the colour. The short wavelength colours blue and violet are scattered in the air much more than other colours, hence the sky appears blue. However, at sunset and sunrise, the sun is low on the horizon, and the light has to pass through more air, which also means more molecules to scatter the light. The result is that the blue and violet light is scattered out of your sight, while the other colours with longer wavelength brakes through the atmosphere and find their way to your eyes. This is why sunsets may appear yellow, orange and/or red.
