More than 7 Billion Individuals Around the Globe Anticipated to Experience Total Lunar Eclipse in September
On September 7, 2025, a captivating moon with a red hue will embark on its journey across the night sky. This astronomical phenomenon marks our second total lunar eclipse of the year, chiefly observable in certain regions of Asia, Australia, the Pacific, and the far eastern areas of Africa until September 8, 2025. In total, approximately 4.9 billion people will witness the entire duration of the eclipse, while 7.1 billion individuals—or roughly 87% of the global populace—will catch at least part of the eclipse’s early stages.
Total lunar eclipses of this nature happen when the Earth is situated directly between the sun and the moon in a linear alignment. This setup enables sunlight to shine on the moon, albeit after it has traversed the Earth. As the sunlight moves through our atmosphere, it gets scattered, filtering out the shorter, blue wavelengths and allowing the longer, red wavelengths to predominate. During the height of the eclipse, the moon is enveloped in a striking reddish tint, which has led to its “blood moon” designation.
Regrettably, this particular eclipse will not be viewable in North, Central, and South America. This is due to these areas having already seen the blood moon earlier this year, around March 13-14. Fortunately, lunar eclipses adhere to a well-defined pattern known as the “Saros cycle,” governing the “periodicity and recurrence” of eclipses, repeating every 18 years, 11 days, and 8 hours, as per NASA. Stargazers will have to be patient until March 3, 2026, for the next blood moon, with its totality visible across the United States, except for the East Coast. The full eclipse will be observable in Hawaii, Alaska, and the western parts of both the U.S. and Canada.
Next August, a subsequent partial eclipse will take place in the Americas, while a total solar eclipse will be seen in Greenland, Iceland, Spain, Russia, and a small section of Portugal.

The upcoming total lunar eclipse, or “blood moon,” will transpire between September 7–8, 2025, and will be fully or at least partially visible to around 7.1 billion people.
