Unusual winter weather in the northern hemisphere has brought the strange sight of so-called light pillars over Finland.
During cold spells flat ice crystals flutter around in the atmosphere, and often turn to snow. The ice crystals reflect light from the ground, forming columns of light that appear vertical, mystical images that go up to heaven.
In bright sunlight similar clouds of ice crystals also form vertical light columns that some call sun-pillars
Are such phenomena from northern latitudes the source of an idea that the Norwegian artist Edvard Munch used in some of his paintings? His pillars are weird symbols of life and vitality, mysteriously intruding into his dark world.
