                   Red Sprite Lightning over the Czech Republic

      Explanation: What are those red filaments in the sky? They are a rarely   
      seen form of lightning confirmed only about 35 years ago: red sprites.   
      Research has shown that following a powerful positive cloud-to-ground   
      lightning strike, red sprites may start as 100-meter balls of ionized   
      air that shoot down from about 80-km high at 10 percent the speed of   
      light. They are quickly followed by a group of upward streaking ionized   
      balls. The featured image was taken late last month from the Jeseniky   
      Mountains in northern Moravia in the Czech Republic. The distance to   
      the red sprites is about 200 kilometers. Red sprites take only a   
      fraction of a second to occur and are best seen when powerful   
      thunderstorms are visible from the side.
