[net.astro] StarDate: October 18 The Ocean in the Autumn Sky

There's an ocean in the autumn sky -- which we'll tell you about --
right after this.

October 18  The Ocean in the Autumn Sky

If you look toward the south this month, you'll see what looks like an
empty sky.  The southern sky in autumn has stars -- but they tend to be
faint, and so city lights wash them out.

True darkness and a star chart reveal that many constellations in this
region have something in common.  The southern autumn sky represents an
ocean, and many of the constellations are named for beings which live
under water.

In the south, you'll find Capricornus, the Sea Goat -- one of the
twelve zodiacal constellations.  The Sea Goat is supposed to have the
head of a goat and the tail of a fish!

You'll also see a regular fish in the south this month -- Pisces
Austrinus, the Southern Fish.  It's not to be confused with the other
constellation Pisces, the zodiacal constellation.  It so happens that
the other Pisces is located in this same celestial ocean -- in pretty
much this same region Both fish constellations are very faint, although
Pisces Austrinus has a single bright star, called Fomalhaut.

Moving on from the little fish, we come to a big fish -- the
constellation Cetus, the Whale.  The whale is supposed to be a monster
and figures in a legend about a princess who was almost devoured.  But
in a dark-enough sky, this constellation can be seen have a funny
lop-sided head that makes it look downright friendly.

So that's a sea goat, some fish and a whale, all located south this
month -- in the ocean in the autumn sky.
