This rare alignment will delight stargazers. On Thursday, April 24, and Friday, April 25, Venus, Saturn, and the crescent moon will align to look like a smiley face. The rare alignment will be the most visible a few hours before sunrise.

Venus and Saturn will align with a crescent moon to create the illusion of a smiley face in the sky on the morning of April 24 and April 25. NASA and EarthSky say that the two planets, along with the moon, will appear low on the horizon in the east.

The crescent moon will be the centerpiece of April's final astronomical event as it bunches up with Venus, Saturn and Mercury in the eastern sky on Friday morning.
