Crescent Moon Aligns with Mars and Regulus This Weekend: Viewing Guide

On the evening of June 28, 2025, stargazers across the United States will have the opportunity to witness a spectacular celestial alignment featuring the crescent moon, the planet Mars, and the bright star Regulus. This astronomical event will occur shortly after sunset, approximately 20 degrees above the western horizon, providing a stunning view for those eager to observe the night sky.

The crescent moon will take center stage as it aligns with Mars and Regulus, becoming visible shortly after sunset. Astronomical experts suggest that the alignment will be best viewed within the first hour of dusk, as the trio of celestial bodies will swiftly descend below the horizon about three hours later. According to Dr. Emily Carter, an astronomer at the California Institute of Technology, “This alignment provides an exceptional opportunity for amateur astronomers and casual observers alike to connect with the cosmos.”

Following the June 28 event, the moon will continue its celestial dance, moving to the lower right of Mars on June 29, where it will appear to sweep beneath the Red Planet. The close proximity of the moon to Mars—within one degree—will create an engaging visual for those observing from the ground.

Significantly, a rare phenomenon known as an 'occultation' will occur during this period. In certain regions, including parts of Peru, Ecuador, Colombia, and Clipperton Island, viewers will see the moon pass directly in front of Mars, blocking it from view. Dr. Sarah Johnson, a professor of astronomy at Harvard University, emphasized the uniqueness of this event, stating, “Lunar occultations of planets are relatively rare and provide a fascinating insight into the dynamics of our solar system.” This occultation will take place around 6:57 p.m. EDT (22:57 GMT) on June 29, 2025.

To best capture the alignment and occultation, enthusiasts are advised to use quality telescopes and cameras. The Celestron NexStar 4SE telescope has been recommended as an ideal tool for beginners wishing to enhance their stargazing experience. Additionally, various guides are available for those interested in astrophotography, allowing readers to document this celestial event.

The significance of this alignment extends beyond mere aesthetics. Such events often inspire curiosity and interest in astronomy among the public, fostering a deeper appreciation for space science. Moreover, they provide valuable opportunities for educational outreach and community engagement.

As the alignment approaches, stargazers are encouraged to prepare for an evening of celestial wonder. With clear skies and an unobstructed view of the western horizon, many will surely find themselves enchanted by the beauty of the cosmos. Observing the moon, Mars, and Regulus in close proximity serves as a reminder of our place in the universe and the dynamic nature of our solar system. Future astronomical events will continue to captivate audiences, inviting all to explore the mysteries of the night sky.
