Northern Lights in Iceland
The Northern Lights (or Aurora Borealis) are natural, colorful light displays, usually visible at night in the polar regions. The lights often appear as “curtains” of green that constantly evolve and change into all colors of the rainbow.
The sun ejects high-energy charged particles called ions that travel into space 300-1200 kilometers per second. This “solar wind” interacts with the Earth’s magnetic field in the upper atmosphere and glows in bright colors.
Sigurdur H Stefnisson has dozens of amazing photographs of the Northern Lights in Iceland. For this photo, Sigurdur says: “Iceland is within that belt where auroras are very common. Here Siggi captured this beautiful scene of the auroras in full swing, and the red color is caused by the solar particles hitting high altitude oxygen.”
