This mysterious winter landscape, which looks as if three suns are embracing the horizon, was captured while exploring the mountainous area near Abisko National Park in Sweden on Feb. 3. The two bright points shining on either side of the Earth’s sun are known as parhelia, mock suns, or sun dogs.
Parhelia occurs when hexagonal ice crystals suspended in hazy air reflect and refract sunlight. This bright parhelia, commonly seen in winter and high latitude areas, sits on the 22-degree ice halo surrounding the sun.
