The breathtaking Vestrahorn mountain on Iceland's Stokksnes peninsula is the perfect stage for the Northern Lights, one of nature’s most magical phenomena. Here, the mountain's rugged profile is mirrored by a frozen, glassy surface, creating a double view of the aurora that sweeps across the sky.

The colors in the Northern Lights—green, pink, red, and sometimes even purple—are produced as solar particles collide with Earth's atmosphere. When these particles interact with oxygen at lower altitudes, a green glow appears, while rarer red hues result from higher-altitude oxygen interactions. Nitrogen, meanwhile, can give off blue and purple colors at various altitudes.

The Northern Lights are more commonly seen in the polar regions because the Earth's magnetic field funnel the solar particles towards the polar regions. The intensity of the Northern Lights is affected by the amount of solar activity, so they can be more or less visible at different times.
