Witness the Spectacular Blood Moon Lunar Eclipse on Sept. 7-8
On September 7-8, 2025, observers across parts of Asia, western Australia, and eastern Europe will have the opportunity to witness a total lunar eclipse, resulting in a mesmerizing “blood moon.” This phenomenon occurs when Earth positions itself directly between the sun and the moon, casting a shadow that transforms the lunar surface into a vibrant red hue.
The eclipse will unfold in several distinct phases, each offering a unique view of this cosmic event. The initial phase begins at 11:28 a.m. EDT (1528 GMT) on September 7, as the moon enters Earth’s penumbral shadow. During this phase, the shading will be subtle and may first be noticeable as a faint darkening on the upper left portion of the lunar disk, approximately one hour after the penumbral phase commences.
As the eclipse progresses, the moon will drift into the umbral shadow at 12:27 p.m. EDT (1627 GMT). This part of the eclipse presents a sharper contrast, as Earth’s shadow begins to cover the lunar disk more dramatically. At this point, approximately 75% of the moon’s surface may take on a deep red-brown color, a result of longer, red wavelengths of sunlight bending through Earth’s atmosphere.
The climax of the eclipse, known as totality, will occur at 1:30 p.m. EDT (1730 GMT). During this striking phase, the entire lunar disk will be enveloped in Earth’s umbra, creating the blood moon effect. The color and brightness of the moon will vary based on atmospheric conditions, including the presence of dust. Totality is expected to last approximately 82 minutes, with the maximum eclipse occurring at 2:11 p.m. EDT (1811 GMT).
As the eclipse begins to conclude, the umbra will start to recede from the moon at 2:52 p.m. EDT (1852 GMT). Viewers will see a bright crescent reemerge on the left edge of the lunar disk, eventually illuminating the entire surface as the eclipse comes to a close at 4:55 p.m. EDT (2055 GMT).
Those unable to view the eclipse in person can still experience this astronomical event through free livestreams available online. The total lunar eclipse will be followed by a partial solar eclipse on September 21, 2025, visible from regions including southern Australia and various Pacific islands.
Observers are encouraged to safely enjoy the celestial spectacle with the naked eye, binoculars, or through a telescope, as there is no need for eclipse glasses typically required for solar events. The upcoming blood moon lunar eclipse offers a fascinating opportunity to witness the interplay between celestial bodies, making it a highlight for astronomy enthusiasts and casual observers alike.
