Colorful Aurora over Icelandic Waterfall
NASA
- An April 2025 photograph captured a vibrant aurora display over Iceland's Skógafoss waterfall using a single 5-second exposure.
- Auroras occur when solar wind particles are trapped by the Earth's magnetosphere and collide with atmospheric gases near polar regions.
- Color variations, including red, green, blue, and pink, depend on the specific gas species and altitude of the particle collisions.
Viewing Conditions
- Successful aurora observation requires a combination of high solar activity, dark skies, and clear weather.
- High-latitude locations are typically required for visibility.
- Northern lights are generally more accessible than southern lights due to the greater availability of landmass near the Antarctic Circle compared to the North.
