The Pleiades -- and their dark association with Halloween -- right
after this.

October 31  The Pleiades at Halloween

This dark night -- with the moon on the wane and visible in our sky
only after midnight -- you might take time to pick out the little star
cluster known as the Pleiades.

This star cluster is one of the most noticed objects in the sky.  It's
compact and yet has a definite shape -- that of a tiny dipper.  The
Pleiades has been important to stargazers for thousands of years --
but, in ancient times, it was associated with a dark time of year.

The reason isn't hard to understand when you realize that the stars
mark the seasons on Earth by reappearing in our sky at the same time
each year.  The Pleiades can be found in the evening sky -- to be
overhead at midnight -- at a time when the days are growing shorter.
The sun rides lower in the sky -- the crops no longer grow.  It was
said that souls of the dead left Earth for the Underworld when the
Pleiades hung overhead at midnight.  The Egyptians, ancient Britons,
Mexicans, Chinese, Japanese and others all observed this fearful time
of year when the Pleiades reached its midnight culmination.  Our
celebration of Halloween stems from their ancient rituals.

Interestingly enough, people living in the southern hemisphere had a
different impression of the Pleiades star cluster.  For them, the
Pleiades overhead at midnight marked the coming of spring.  So for
them, the Pleiades were a sign of light, warmth and rebirth.

You can pick out the Pleiades just by looking.  Look overhead at
midnight for a tiny, hazy cluster -- shaped like a little dipper.
