     [2]The featured image shows the famous Horsehead nebula in Orion, a
   dark dust figure superposed on glowing gas. Please see the explanation
                       for more detailed information.

   Explanation: The famous Horsehead Nebula in Orion is not alone. A deep
   exposure shows that the [4]dark familiar shaped indentation, visible
   just right of center, is part of a [5]vast complex of absorbing [6]dust
   and [7]glowing gas. The featured [8]spectacular picture details an
   intricate [9]tapestry of gaseous wisps and dust-laden [10]filaments
   that were created and sculpted over eons by [11]stellar winds and
   ancient [12]supernovas. The [13]Flame Nebula is visible in orange just
   to the Horsehead's left. To highlight the dust and gas, most of the
   [14]stars have been [15]digitally removed, although a notable exception
   is [16]Alnitak, just above the Flame Nebula, which is the rightmost
   star in [17]Orion's famous belt of three aligned stars. The
   [18]Horsehead Nebula lies 1,500 [19]light years distant towards the
   [20]constellation of Orion.
