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 picture the part of the Orion Nebula known as M43 in great
   detail including many find streams of dust. Please see the explanation
                       for more detailed information.

   Explanation: Where do the dark streams of dust in the Orion Nebula
   originate? This part of the [4]Orion Molecular Cloud [5]Complex,
   [6]M43, is the often imaged but rarely mentioned neighbor of the more
   famous M42. [7]M42, seen in part to the upper right, includes many
   bright stars from the [8]Trapezium star [9]cluster. [10]M43 is itself a
   star forming region that displays intricately-laced streams of dark
   dust -- although it is really composed mostly of glowing [11]hydrogen
   gas. The entire [12]Orion field is located about 1600 [13]light years
   away. Opaque to [14]visible light, the picturesque dark [15]dust is
   [16]created in the outer atmosphere of massive [17]cool stars and
   expelled by strong [18]outer winds of [19]protons and [20]electrons.
