Explanation:
The clouds surrounding the star system Rho Ophiucus compose one of the closest star  
forming regions.   
  
Rho Ophiucus itself is a   
binary star system visible in the   
light-colored region on the image right.  
  
The star system, located only 400   
light years away, is distinguished by its   
colorful surroundings,   
which include a red   
emission nebula and numerous   
light and dark brown dust lanes.  
  
Near the upper right of the Rho Ophiucus   
molecular cloud system is the yellow star   
Antares, while a distant but coincidently-superposed   
globular cluster of stars,   
M4, is visible between Antares and the red   
emission nebula.  
  
Near the image bottom lies IC 4592, the   
Blue Horsehead nebula.    
  
The blue glow that surrounds the Blue Horsehead's eye -- and other stars around the  
image -- is a reflection nebula composed of fine dust.  
  
On the   
above image left is a geometrically angled reflection nebula   
cataloged as   
Sharpless  
1.    
  
Here, the bright star near the dust vortex creates the light of surrounding   
reflection nebula.  
  
Although most of   
these features  
are visible through a small telescope pointed toward the constellations of   
Ophiucus,   
Scorpius, and   
Sagittarius, the only way to see the intricate details of the dust swirls, as  
featured above, is to use a   
long exposure camera.
