A celestial event will unfold on January 13, 2025, when the full moon will obscure Mars for nearly four hours. This phenomenon, known as a lunar occultation, will coincide with Mars reaching opposition, where it aligns directly opposite the Sun as viewed from Earth. During this period, Mars will appear at its brightest and closest to Earth in 2025. Skywatchers across the United States, parts of Canada, Mexico, and regions of Western Africa will have the opportunity to witness this rare occurrence.

Event Details and Viewing Recommendations

According to reports, Mars will vanish behind the moon's edge at approximately 8:44 p.m. EST and reappear around 12:52 a.m. EST the following day. The event will be visible in most parts of the mainland United States, some areas of Canada, Mexico and Western Africa, though the exact timing may vary depending on your location. Those interested in observing are encouraged to choose spots with minimal light pollution and allow time for their eyes to adjust to the dark.

Optimal Equipment for Observing

The Red Planet, described by astronomers as glowing with a golden tint, can be seen with the naked eye during the event. For a closer and more detailed view, high-powered binoculars or telescopes are recommended. These tools may reveal Mars' red hues, its northern polar ice cap, and geological features like Valles Marineris, the solar system's largest canyon. This canyon spans approximately 3,000 kilometres in length and reaches depths three times greater than the Grand Canyon.

Significance and Future Occurrences

This is reported to be the only lunar occultation of Mars observable from the United States this year. Following this, a similar event will take place in February, visible from parts of Scandinavia, Russia, and Asia. After 2025, the next easily viewable occultation for U.S.-based observers will not occur until 2042. The rare alignment makes this event particularly significant for astronomy enthusiasts and casual stargazers alike.
