Super blood moon in 2025 promises 82 minutes of unforgettable lunar eclipse

On the night of September 7th to 8th, 2025, a total lunar eclipse, known as a super blood moon, promises an 82-minute display of totality, the longest of the year. The phenomenon, which dyes the Moon red, will be visible in regions such as Europe, Africa, eastern Australia and New Zealand, but not in Brazil, where the Moon will be below the horizon. Astronomers and enthusiasts will be able to follow the event via live broadcasts on platforms such as YouTube, offered by institutions such as NASA and ESA.

The eclipse will begin at 12:28 pm and end at 5:55 pm Brasília time, with the peak between 2:30 pm and 3:52 pm. A supermoon occurs when the full Moon is at perigee, appearing up to 14% larger and brighter. The reddish color appears due to the dispersion of sunlight in the Earth’s atmosphere, creating a unique visual effect.

• Eclipse phases: Penumbral, partial and total.
• Recommended platforms: NASA, ESA, Time and Date.
• Total duration: About five and a half hours.

What makes the event special

The 2025 super blood moon stands out for its duration of 82 minutes of totality, the longest of the year. The Moon will be 2.7 days from perigee, which makes it appear larger in the sky. During totality, the Earth’s shadow will completely cover the Moon, intensifying the red hue. Atmospheric conditions, such as dust, can make the coloring even more vibrant.

How to follow in Brazil

Although Brazil does not have direct visibility, live broadcasts will allow the public to follow the eclipse. Platforms such as YouTube and astronomy websites will offer images captured by telescopes. The National Observatory and other Brazilian institutes plan lives with comments from experts. For a good experience, it is recommended to start viewing at 1:15 pm, Brasília time. A stable connection and a peaceful environment are ideal for enjoying scientific narrations.

The science of the phenomenon

The red tone of the super blood moon occurs due to Rayleigh scattering, when sunlight passes through the Earth’s atmosphere, filtering blue tones and highlighting red tones. The intensity of the color varies depending on the dust or clouds in the atmosphere. By 2025, 36% of the lunar diameter will be in the umbra, intensifying the effect. The precise alignment between Sun, Earth and Moon creates a unique visual spectacle. Photographers and astronomers eagerly await to capture the event.

Lunar eclipse steps

The 2025 eclipse will have six phases, starting with penumbral dimming, followed by partial, when the umbra covers part of the Moon. Totality, with the Moon completely red, lasts 82 minutes. After peaking, the Moon gradually returns to normal brightness, over a five and a half hour process.
