[net.astro] StarDate: October 24 New Moon

Today is the only day this month that you can't see the moon.  We'll
tell you why -- right after this.

October 24  New Moon

The moon moves in orbit around the Earth in nearly -- but not quite --
the plane of Earth's orbit around the sun.  That's why we don't have a
solar eclipse once each month, even though the moon gets in between the
Earth and sun that often.  When the moon passes between the Earth and
sun, it generally passes just above or below the sun from our
vantagepoint.

That's the case today -- the day of new moon for the month of October.
Today's new moon is between the Earth and sun -- not directly in
between -- but as close as it'll come this month.  Because it's hidden
in the sun's glare today, the moon won't be visible anywhere in the
sky.  But you may have seen the waning crescent moon Tuesday morning
before dawn -- and you may see the waxing crescent in the west after
sunset on Thursday.

To see the moon Thursday evening, look right after sunset toward a
western horizon free of trees, buildings and clouds.  The moon will
have just emerged from being between the Earth and sun -- from our
vantagepoint, it'll still be near the sun in the sky -- just below a
very bright object, the planet Venus.  If you do see the moon in the
west Thursday evening, or even if you don't, be sure to look again
Friday evening.  Then the moon will have moved higher in the west --
and it'll be right next to Venus.
