This picture stood out to me as it looked like a picture of fireworks in the night sky, however it was much softer colors and much smoother texture. This picture is of an aurora above Tromso, Norway. As the picture was taken over a length of time, the streaks seen inside of the aurora are actually satellites moving through the sky. Auroras are also known as Northern and Southern Polar Lights, the specific ones in this picture being Northern lights or the Aurora Borealis. These auroras are caused by collisions between charged particles and air molecules. They are often predicted based upon the time period of magnetic occurrences near the sun.
