On September 7-8, 2025, a total lunar eclipse will showcase a spectacular “blood moon” as Earth’s shadow envelops the lunar surface. This astronomical event presents an opportunity for observers across parts of Asia, western Australia, and eastern Europe to witness the moon transition into a deep red hue, a result of sunlight refracting through Earth’s atmosphere.
A total lunar eclipse occurs when the Earth passes directly between the sun and the moon, casting a shadow on the moon and leading to a captivating display. During this event, viewers can safely observe the eclipse with the naked eye, through binoculars, or a telescope. Unlike solar eclipses, there is no need for protective eyewear.
The eclipse will unfold in several distinct phases, starting with the penumbral phase at 11:28 a.m. EDT (1528 GMT) on September 7. In this stage, Earth’s outer shadow will subtly darken the upper left portion of the lunar disk. Sharp-eyed observers may notice this gradual shadow moving across the moon’s surface.
At 12:27 p.m. EDT (1627 GMT), the moon will drift into the umbral shadow, marked by a noticeable shift in darkness. During this partial phase, approximately 75% of the lunar surface will be obscured, adopting a reddish-brown color as sunlight refracts through Earth’s atmosphere.
The peak of the eclipse, known as totality, will occur at 1:30 p.m. EDT (1730 GMT). During this time, the moon will transform into a vivid blood moon, illuminated by the refracted light of sunsets and sunrises happening simultaneously across the planet. Totality will last approximately 82 minutes, with the maximum eclipse occurring at 2:11 p.m. EDT (1811 GMT). Observers may notice variations in brightness across the lunar disk, particularly around Mare Nubium, as different portions of the moon experience varying degrees of shadow.
As the eclipse progresses, Earth’s umbral shadow will begin to recede at 2:52 p.m. EDT (1852 GMT), revealing a crescent shape on the left edge of the moon. The partial eclipse phase will continue for over an hour, concluding at 4:55 p.m. EDT (2055 GMT) as the penumbral shadow retreats completely.
For those unable to view the eclipse in person, various free livestreams will be available, allowing global audiences to experience the event virtually. Following this total lunar eclipse, a partial solar eclipse is scheduled for September 21, 2025, visible from parts of southern Australia, several Pacific islands, and Antarctica.
This total lunar eclipse presents a unique opportunity for skywatchers to engage with a breathtaking celestial phenomenon. Whether viewed directly or through digital platforms, the blood moon is sure to captivate audiences around the world.
