      An image of Earth from space shows an unusual multi-colored jet in the   
         middle of the frame. Please see the explanation for more detailed   
                                   information.   
      
                     Up from the Earth: Gigantic Jet Lightning

      Explanation: What's that rising up from the Earth? When circling the   
      Earth on the International Space Station early in July, astronaut   
      Nicole Ayers saw an unusual type of lightning rising up from the Earth:   
      a gigantic jet. The powerful jet appears near the center of the   
      featured image in red, white, and blue. Giant jet lightning has only   
      been known about for the past 25 years. The atmospheric jets are   
      associated with thunderstorms and extend upwards towards Earth's   
      ionosphere. The lower part of the frame shows the Earth at night, with   
      Earth's thin atmosphere tinted green from airglow. City lights are   
      visible, sometimes resolved, but usually creating diffuse white glows   
      in intervening clouds. The top of the frame reveals distant stars in   
      the dark night sky. The nature of gigantic jets and their possible   
      association with other types of Transient Luminous Events (TLEs) such   
      as blue jets and red sprites remain active topics of research.
