Look to the eastern sky late Thursday, and a clear horizon will show you this unusual, grinning planet alignment.

Venus, Saturn and the moon will form a triple conjunction, appearing to look like a smiley face in a sky. Here's how and when to witness the rare event.

Venus and Saturn will be in just the correct spot in their revolution around the sun to match up with the waning crescent moon, making the smiley face appear. Everything is expected to line up Friday morning around 5:30 a.m.
