tähtikuvaa

Tähtikuvaa is a Finnish term that refers to a type of exceptional scenery in the northern parts of the country. The phenomenon occurs when the sun is low on the horizon, and the light passes through the Earth's atmosphere, causing the surrounding landscape to be illuminated in a striking manner.

The resulting vistas are characterized by a range of colors, with shades of pink, orange, and red dominating the scene. The colors are produced by the scattering of shorter wavelengths of light, such as blue and violet, by the atmosphere, allowing longer wavelengths, like red and orange, to reach the observer's eyes.

Tähtikuvaa is a Finnish expression, literally translating to "star-like view." The term is often used to describe the breathtaking scenery that can be observed in rugged wilderness areas and national parks, such as Lapland and Oulangan Tuomiopietä.

The phenomenon is at its most spectacular during the summer solstice, when the sun remains above the horizon for 24 hours. This extended period of daylight allows for the optimal viewing conditions of tähtikuvaa. The scenery also takes on a mesmerizing quality as the colors of the landscape seem to shift and change in response to the position of the low-lying sun.

Tähtikuvaa is a manifestation of the natural world's ability to create beauty and wonder through simple, yet potent, natural processes. By understanding the scientific principles behind the phenomenon, it becomes clear that the unique setting of the Finnish wilderness contributes to the creation of these captivating vistas.
