Northern Lights illuminate the skies of Alaska

Eyewitness footage captured on Tuesday (April 20), showed the stunning natural phenomenon illuminating Fairbanks, a city known for its optimal Northern Lights viewing due to its location in the so-called "Aurora Oval".

Any Witteman, who filmed the spectacle, said residents usually see the light displays on average three or four nights a week between August and April.

The Aurora Borealis can be seen above Earth's northernmost and southernmost regions. The auroral displays are associated with the solar wind - electrically charged particles continuously spewing outward from the sun. Earth's magnetic field lines reach far out into space as they store energy from the solar wind.
