Astronomy Picture Of The Day: Aurora Over Norway, 2010 September 20.
We've all seen pictures of the Aurora Borealis from the Alaskan ground. Auroras are photographed often due to there beauty. This specific picture taken above Tromso Noway is unlike anything I personally have ever seen. The sky it stretches is absolutely incredible. It's superbly bright. Even the landscape below is beautiful. It's interesting how the subscript points out the auroras never block light behind them (for example stars, planets, or even airplanes). Thus everything behind this aurora is still visible which makes for an even more beautiful sight. Auroras are caused by collisions between charged particles from the magnetosphere and air molecules from Earth's atmosphere. They are even visible from space. The combination of its beauty and its scientific prerequisites makes the aurora one of the coolest, most interesting things in the sky in my opinion.
P.S. LOOK AT ALL OF THOSE STARS.
