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.
