On the evening of May 29, 2025, skywatchers across the United States and much of the Northern Hemisphere will be treated to a rare and whimsical celestial alignment: a “smiley face” formed by the twin stars Castor and Pollux in the constellation Gemini and a slender crescent Moon.

About 45 minutes after sunset, look toward the western horizon. The bright stars Castor and Pollux—representing the eyes—will be visible about 5 degrees above a thin, waxing crescent Moon, which takes the shape of a lopsided grin. Together, these celestial objects create the illusion of a cheerful face gazing back at you from the heavens145.

The “smiley face” will remain visible for several hours, with the Moon and stars gradually setting as the night progresses. The alignment is best viewed from a location with a clear western view, away from city lights. Binoculars are not required but can enhance the experience, especially for those hoping to spot fainter stars or enjoy the Moon’s delicate crescent in detail.

This delightful event is a reminder of the beauty and playfulness of the night sky, offering a perfect opportunity for families, photographers, and stargazers to enjoy a memorable moment under the stars14.
