Explanation:
It is the most famous star cluster on the sky.  The    
Pleiades can be seen    
without binoculars from even the depths of a    
light-polluted city.     
Also known as the Seven    
Sisters and    
M45,    
the Pleiades    
is one of the brightest and most    
easily visible   
open clusters on the sky.    
The Pleiades    
contains over 3000 stars, is about 400 light years away, and only 13 light   
years across.  Quite evident in the above photograph is the blue    
reflection nebula that surrounds the    
bright cluster stars.  Low mass, faint,    
brown dwarfs have    
recently been found in the Pleiades.
