Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

      [2]The edge of the Earth is seen from space at night. The curving
   horizon is tinted green but a red and blue jet rises from left. Please
             see the explanation for more detailed information.

   Explanation: What's that on the horizon? When circling the Earth on the
   [9]International Space Station early [10]last month, astronaut
   [11]Matthew Dominick saw an unusual type of lightning just beyond the
   Earth's edge: a gigantic jet. The powerful jet appears on the left of
   the [12]featured image in red and blue. [13]Giant jet lightning has
   only been known about for the past 23 years. The atmospheric jets are
   associated with thunderstorms and extend upwards towards [14]Earth's
   ionosphere. The lower part of [15]the frame shows the [16]Earth at
   night, with Earth's thin atmosphere tinted green from airglow. [17]City
   lights are visible, sometimes resolved, but usually creating diffuse
   white glows in intervening clouds. The top of [18]the frame reveals
   distant stars in the dark night sky. The nature of [19]gigantic jets
   and their possible association with other types of [20]Transient
   Luminous Events (TLEs) such as [21]blue jets and [22]red sprites
   remains an [23]active topic of research.
