If you are visiting Alaska, you just might get treated to the most beautiful light show on earth. The Northern Lights, also called aurora borealis, are a spectacular phenomenon caused by the sun’s activity during solar storms. Shimmering, glowing curtains of light seem to dance in the night sky. These can appear as green, red, pink, blue, or violet, even orange, depending on the gases involved. Hopefully you will get to enjoy this display of living color!
