Sky Highlights

March begins with Venus and Jupiter, the brightest objects in the night sky other than the Moon, forming a dazzling pair in the west at nightfall, but they quickly separate, with Jupiter disappearing in the sunset by month’s end. Venus, on the other hand, climbs higher, sliding near the shoulder of the bull, represented by the Pleiades star cluster, a third of the way through April. The Moon teams up with Venus and the bull’s orange eye, the star Aldebaran, later on.
