Tour July’s Sky! | May 30th, 2012

This month, you can see a pair of planets before sunrise and another pair after sunset. In each case, one of them is situated near a bright star.

Before dawn, you can see dazzling Venus and not-as-bright Jupiter. Right next to Venus, but seemingly much dimmer, is the bright star Aldebaran. Throughout the month these three beacons rise higher in the predawn twilight and move farther apart.
