   Explanation: Taken with a camera fixed to a tripod, many short
   exposures were aligned with the stars to unveil this beautiful, dark
   night sky. [7]Captured near the rural village of Albany`a at the
   northeastern corner of Spain, the three stars of Orion's belt stretch
   across top center in the starry frame. [8]Alnitak, the easternmost
   (left) of the belt stars is seen next to the more diffuse glow of the
   [9]Flame Nebula and the dark notch of the famous [10]Horsehead. Easily
   visible to the naked-eye [11]The Great Nebula of Orion is below the
   belt stars. A mere 1,500 light-years distant, it is the closest large
   stellar nursery to our fair planet. Best seen in photographs, the broad
   and faint arc of [12]Barnard's Loop seems to [13]embrace Orion's
   brighter stars and nebulae though. In the northern spring the familiar
   [14]northern winter constellation is setting. Near the western horizon
   toward lower right Orion's [15]apparently bright blue supergiant Rigel
   just touches the branches of a pine tree.
