"Why do the Stars Change With the Seasons? and; Two Cosmic Signs that Fall is Here"

Scheduled air date: 2003 Oct 13-19

As the Earth revolves around the Sun throughout its year, its night side faces a different portion of the celestial "sphere."

During Autumn, the constellation of Pegasus, the asterism known as "The Great Square" and the Pleiades star cluster—also known as the Seven Sisters—are predominant in the evening sky.  Mars is still visible as a bright copper-orange "star" in the south after dark.
(Shown about two hours after sunset during the second half of October for mid-Northern latitudes.  The inset shows a binocular view of the star cluster.)
