Northern Lights
It’s no wonder that ancient theories about the phenomenon known as the Aurora Borealis varied from the wrath of invisible gods to fires sparked by the waving of a mythical foxes tail, the latter explanation accounting for the Finnish word for the Aurora, fox’s fires or ‘revontulet’. The magical displays of shifting coloured light are strange and beautiful enough to transcend their scientific explanation, which says that the Northern Lights are caused by matter, or solar wind, from solar storms colliding with the Earth’s atmosphere. The occurrence of flares on the surface of the sun makes it possible to predict the liveliness of the Northern Lights in areas in which they are common such as northern Finland, where they may be visible on clear nights up to 200 times a year. The Aurora is also visible in the south, including Helsinki, in areas of low light pollution as many as 20 times a year.
