Late summer offers the Teapot of Sagittarius and the nearby arc of the Scorpion's Tail in the evening, the Perseid meteor shower, and a spectacular pairing of Venus and Jupiter before dawn.August will be a busy skywatching month in the evening sky. Two bright planets, Mars and Saturn, are low in the west at dusk. They’re joined by the star Spica. Look for a line of three obvious “stars,” all about the same brightness. The one on the left is Saturn, on the right is Spica, and Mars is in between.
