Explanation:
Follow the handle of   
the Big Dipper    
away from the dipper's bowl, until   
you get to the handle's last bright star.   
   
Then, just slide your telescope a little south and west and   
you might find this   
stunning pair of interacting galaxies,   
the 51st entry   
in Charles   
Messier's famous   
catalog.   
   
Perhaps the original   
spiral nebula, the large galaxy with   
well defined spiral structure is also cataloged as   
NGC 5194.   
   
Its spiral arms and dust lanes   
clearly sweep in front of its companion galaxy (left),   
NGC 5195.   
   
The pair are   
about 31 million light-years distant and   
officially lie within the angular boundaries of the small constellation   
Canes Venatici.   
   
Though M51   
looks faint and fuzzy to the human eye,   
the above long-exposure, deep-field image    
taken earlier this year shows much of the    
faint complexity that actually surrounds the smaller galaxy.   
   
Thousands of the faint dots in background of the featured image are actually    
galaxies far across the universe.
