The middle of the night in Galena, Alaska, was icy clear, 30 below, and windy. Getting out of the tent was almost unbearable. We'd given the dogs a massive run earlier in the day in hopes that they would lay still through a long exposure to capture the night sky. Luckily, they were tired and rested under a spectacular display of color pulsing across the horizon.
The Aurora Borealis are the result of charged particles released from the sun’s atmosphere. When these charged particles enter earth’s upper atmosphere—called the thermosphere—they collide with various gases, which define the different colors of each aurora.
Science aside, for anyone lucky enough to see the Aurora Borealis, it is an amazing and humbling experience.
