"Tonight is a night of celestial coincidences. The autumnal equinox -- the beginning of fall -- comes at 11:09 p.m. ET, and for the first time in 19 years, it comes on the same night as a full moon, the one known as the Harvest Moon.
And for good measure, if you are blessed with clear skies tonight, you will see an unusually bright star right near the moon. It's actually not a star at all; it's the planet Jupiter, at "opposition," coming closer to the earth than at any time since 1963."
