Strange shapes and textures can be found in neighborhood of the Cone Nebula. The unusual shapes originate from fine interstellar dust reacting in complex ways with the energetic light and hot gas being expelled by the young stars. The brightest star on the right of the above picture is S Mon, while the region just below it has been nicknamed the Fox Fur Nebula for its color and structure.
Explanation: Strange shapes and textures can be found in neighborhood of the Cone Nebula . The unusual shapes  originate from fine interstellar dust  reacting in complex ways with the energetic light and hot gas being expelled by the young stars. The brightest star on the right of the above picture  is S Mon , while the region just below it has been nicknamed the Fox Fur Nebula  for its color and structure. The blue glow  directly surrounding reflection , where neighboring dust reflects light from the bright star. Thered glow  that encompasses the whole region results not only from dust reflection but also emission  from hydrogen  gas ionized  by starlight. S Mon  is part of a young open cluster of stars  named NGC 2264 , located about 2500 light years  away toward the constellation of the Unicorn (Monoceros ). The origin of the mysterious geometric Cone Nebula , visible on the far left, remains a mystery .
