   Explanation: Celestial sights of the southern sky shine above a
   [5]cloudy planet Earth in this gorgeous night sky view. The scene was
   captured from an airliner's flight deck at 38,000 feet on a steady
   westbound ride to Lima, Peru. To produce [6]the sharp airborne
   astrophotograph, the best of a series of short exposures were selected
   and digitally stacked. The broad band of the [7]southern Milky Way
   begins at top left with the dark [8]Coalsack Nebula and Southern Cross.
   Its expanse of diffuse starlight encompasses the the Carina Nebula and
   large Gum Nebula toward the right. Canopus, alpha star of Carina and
   second brightest star in Earth's night is easy to spot below the Milky
   Way, as is the dwarf galaxy known as the [9]Large Magellanic Cloud. The
   Small Magellanic cloud just peeks above the cloudy horizon. Of course,
   the South Celestial Pole also lies [10]within the starry southern
   frame.
