The aurora borealis, a natural phenomenon, is caused by solar winds entering Earth's magnetic field. The pink, green, blue and violet lights that appear in Earth's northern hemisphere are always present, but best seen after sunspot activity, according to Space.com.
On March 17, photographer Göran Strand from Östersund, Sweden, captured the aurora borealis produced by the huge solar flare on the sun that sent massive solar winds our way. The 2,464 images he took over four hours was condensed into the stunning time-lapse video above.
