Explanation:
In the vast Orion Molecular Cloud complex,    
several bright blue nebulas are particularly apparent.     
   
Pictured here are two of the most prominent    
reflection nebulas -    
dust clouds lit by the    
reflecting light of bright embedded    
stars.    
   
The more famous nebula is    
M78,    
in the image center, cataloged over 200 years ago.    
   
To its left is the lesser known    
NGC 2071.     
   
Astronomers continue to    
study these    
reflection nebulas to    
better understand how interior stars form.    
   
The Orion complex    
lies about 1500 light-years distant, contains the    
Orion and    
Horsehead nebulas,    
and covers much of the    
constellation of Orion.
