Explanation:
The 1970s  
are sometimes ignored by astronomers,  
  
like this beautiful grouping of reflection nebulae  
in Orion - NGC 1977, NGC 1975, and NGC 1973 -   
usually overlooked in favor of the substantial glow from the  
nearby stellar nursery better known as the  
Orion Nebula.  
  
Found along Orion's sword just north  
of the bright Orion Nebula complex, these reflection nebulae are  
also associated with  
Orion's giant molecular cloud about  
1,500 light-years away, but  
are dominated by the characteristic blue color of interstellar  
dust reflecting  
light from hot young stars.  
  
In this sharp color image a portion of the Orion Nebula appears  
along the bottom border with the cluster  
of reflection nebulae  
at picture center.  
  
NGC 1977 stretches across the field just below center,  
separated from NGC 1973 (above right) and NGC 1975 (above left)  
by dark regions laced with faint red emission from  
hydrogen atoms.  
  
Taken together, the dark regions suggest to many the  
shape of a running man.
