This week two of the brightest planets join forces, and sky-watchers celebrate the change of seasons with a bright full moon.

Saturn and Venus.  Starting on Monday, September 16 after sunset, Venus and Saturn will be having a close encounter that will last most of the week.  Low in the southwest sky, the second planet from the Sun will be the first visible—as the brightest star-like object in the entire heavens.
