Rjukan is a small Norwegian town of roughly 3,300 residents nestled in a valley in northern Norway. Because of its unique geographic location, the town is cloaked in darkness for five months every year.
But not for much longer! A new project is installing mirrors on a mountaintop that overlooks the city and will shine a artificial sunlight into the town. Exposure to sunlight helps ward off depression and sadness, so the town of Rjukan just might be a little more cheerful this winter.
