Spectacular Northern Light Display Illuminates Finnish Sky
Green, purple, pink and yellow lights danced across the sky in striking aurora displays over northern Finland early on Friday.
The Northern Lights are a result of collisions between electrically charged particles from the sun that enter the Earth’s atmosphere. A strong geomagnetic storm was behind this week’s particularly stunning show.
Known as aurora borealis, or the Northern Lights, in the northern hemisphere, they go by aurora australis, or the Southern Lights, in the southern hemisphere.
