Turn your eyes to the east in the early morning hours of Sept. 16 to see the moon conspire with Jupiter and the bright stars of the Gemini constellation to create a lopsided rectangular formation in the late summer sky.
Jupiter will rise above the eastern horizon roughly an hour-and-a-half after midnight on Sept. 16, with the slender crescent moon shining roughly five degrees above it and the twinkling forms of the bright stars Castor and Pollux close to its left. Remember, 10 degrees is approximately the same width as your clenched fist when held out against the night sky!
