A Rare Lunar Spectacle This September
The Blood Moon 2025 is here, and with it comes a breathtaking lunar eclipse that skywatchers won’t soon forget. On Sept. 7, the full moon will transform into a striking shade of red, creating one of the year’s most anticipated celestial events. This moment of totality offers not just science but also awe, as millions of people across the globe turn their eyes skyward.
Why Does the Moon Turn Red?
The moon doesn’t produce its own light. Instead, it reflects sunlight. During a total lunar eclipse, Earth moves directly between the sun and the moon, casting its shadow across the lunar surface. While most sunlight is blocked, some rays sneak through Earth’s atmosphere. Those rays scatter and bend, filtering out blue light and leaving behind deep reds and oranges. The result is the glowing “blood moon.”
Other factors like dust, haze, or smoke in the sky can intensify the red effect. Sometimes, the term “blood moon” also describes certain full moons of autumn, when their color mirrors the seasonal foliage.
When and Where to Watch the Blood Moon
Mark your calendar for Sept. 7, 2025. The eclipse begins at 11:28 a.m. Eastern and lasts until 4:55 p.m. Eastern. Totality—the stage when the moon is fully immersed in Earth’s shadow—stretches for an impressive 82 minutes between 1:30 and 2:52 p.m. Eastern.
Viewers in Australia, India, Cairo, and South Africa will enjoy a clear view of totality. In fact, about 77% of the world’s population will see the full event, and 88% will glimpse at least part of it. Unfortunately, North America will miss this eclipse, but skywatchers there can look forward to March 2–3, 2026, when the next total lunar eclipse becomes visible.
The Science Behind a Lunar Eclipse
A total lunar eclipse happens when the sun, Earth, and moon align in a perfect straight line. Unlike solar eclipses, which require protective glasses, lunar eclipses are completely safe to watch with the naked eye. And while solar totality lasts only minutes, lunar totality can stretch up to nearly two hours, giving watchers more time to enjoy the view.
September’s Full Moon: The Corn Moon
This September’s full moon is also called the “Corn Moon.” The name comes from late summer and early fall, when corn harvesting takes place across the Northern Hemisphere. The moon reaches peak illumination on Sept. 7 at 2:09 p.m. Eastern, though it will appear full on both Sept. 6 and Sept. 7 evenings.
