Alaska Aurora Borealis
The aurora borealis, also known as the northern lights, decorate Alaska’s dark winter nights with splendid arrays of color. Purple, violet, and green are the most commonly observed colors. These colors fall into the mid-range of the color wavelength spectrum, most easily seen by the human eye. Other colors, like dark red, exist on the far end of the spectrum and are more difficult to see. The twisting, dancing, and swirling shapes flood the sky during periods of strong solar activity, delighting the lucky ones who stay up late to watch the night show.
