Plan for April 25, 2025, when astronomers throughout the world will see a remarkable celestial event: a crescent moon, Venus, and Saturn will align to create what astronomers refer to as a “cosmic smile” in the predawn skies.

This planetary alignment is a unique opportunity that anybody with clear access to the eastern horizon may see, unlike many sky events that require specialized equipment or ideal conditions. Even while there are occasional astronomical alignments of several planets and our moon, configurations that create identifiable patterns, such as faces, are still rare and fascinating to viewers.

What’s Making Sky Grin? Planets and Moon Align

When three heavenly bodies appear to be near to one another from Earth, this is known as a triple conjunction. Venus will shine brightly as one “eye” above at this specific alignment, while Saturn will form another “eye” slightly below. Below them both, a slender crescent moon forms a triangle pattern resembling a happy face.

“Venus is higher above the eastern horizon with Saturn lower, and a thin, crescent Moon a bit lower and a little farther north,” NASA Solar System Ambassador Brenda Culbertson told local Kansas TV station KSNT. “The thin, crescent Moon looks like a smile. To some people, the triangle of bright objects may appear as a smiley face.”

From Earth, Venus appears as a bright white point about 25 times brighter than Saturn during conjunction, making it the brightest planet in our solar system. Saturn’s golden color makes it easily visible even if it is less bright. Despite their true sizes, planets do not expand like discs to the naked eye, thus both will seem as brilliant points.

Your Guide to Catching the Smiley Face in the Sky

On Friday, April 25, 2025, viewing opportunities start at approximately 5:30 a.m. local time. Regardless of where they are in the world, observers should get ready for early morning viewing because this cosmic grin shows during predawn hours.

You can only view it about an hour before sunrise due to the reduced visibility. For the best contrast, arrive earlier while the sky is darker. Observers benefit from patience; give their eyes a few minutes to adjust to the darkness for better planet visibility.

If the weather cooperates, this event is accessible from anywhere in the world due to its global visibility. Buildings that block low-horizon vistas can cause problems in metropolitan areas. Conversely, rural or high-altitude areas provide benefits for unhindered visibility.

For observers with apparent horizons, Mercury may make a supplementary appearance. Mercury is difficult to identify and appears much lower than it does in primary formation; if it is spotted, it should be viewed as an extra prize rather than the main object of observation.

For Optimal Viewing

Strategic planning is essential for success, beginning with the right site selection. The best places to see the eastern horizons are those where there are no buildings, hills, mountains, or trees to hinder the view. East-facing beaches, high places, and broad fields offer better vantage angles.

“Anyone wanting to try for a glimpse of the conjunction should find a clear eastern horizon from which to observe,” Culbertson said.

Light pollution significantly affects the quality of stargazing. Excessive artificial lighting in urban areas obscures fainter objects. Wherever feasible, viewers should look for spots away from city lights; parks, rural areas, and places with a designated black sky significantly boost visibility. Online maps of light pollution make it easier to choose the best local viewing locations with the least amount of light interference.

The weather has a significant impact on viewing success. Even light clouds can block off planets and crescents, so clear skies are still crucial. The day before the event, check the weather prediction and prepare a backup viewing place in case it becomes necessary. Higher elevations often stay above the low-level moisture; however, in some areas, morning dew or fog frequently forms during the predawn hours.

Specific regional recommendations for North American viewers include:

• Eastern Seaboard: Beaches that face the ocean provide the impression of eastern horizons.
• Midwest: Wide-open rural regions distant from urban areas
• Mountain states: Slopes in the lower east that overlook the plains
• West Coast: Highlands overlooking valleys to the east
