A total lunar eclipse will take place on September 7-8, 2025, providing a breathtaking spectacle for stargazers around the world. During this event, Earth’s shadow will completely cover the moon, creating what is commonly referred to as a “blood moon.” This celestial phenomenon occurs when Earth aligns perfectly between the moon and the sun, blocking light and casting a reddish hue on the lunar surface.
The phenomenon of a total lunar eclipse is relatively rare. Although the moon goes through its full phases monthly, the specific alignment needed for a total eclipse does not happen every time. About three times a year, however, this alignment occurs, allowing observers to enjoy the sight of the eclipsed moon. As the date approaches, enthusiasts are encouraged to secure their viewing spots, ensuring unobstructed views for both photography and naked-eye observation.
Viewing Details and Timing
The total lunar eclipse will reach its peak at 1:30 p.m. ET (1730 GMT), with totality lasting an impressive 82 minutes. The eclipse will commence globally at 11:28 a.m. (1528 GMT), and each phase will occur simultaneously for all observers on Earth. However, visibility will depend on whether the moon is above the horizon in various locations.
Approximately 5.8 billion people, or about 76% of the global population, located in regions such as Australia, Asia, Africa, and eastern Europe will have the opportunity to witness the eclipse from start to finish. Conversely, observers in the Americas will not be able to see the moon during this event, as it will remain below the horizon throughout the eclipse.
What to Expect During the Eclipse
As the eclipse progresses, viewers will notice the moon taking on a deep red color during totality. This effect is caused by a phenomenon known as Rayleigh scattering, where shorter blue wavelengths of light are scattered by particles in Earth’s atmosphere, while longer red wavelengths pass through. This interaction paints the moon in a striking crimson hue, earning its nickname, the “blood moon.”
For those concerned about cloud cover or the moon’s visibility, Space.com will host a livestream of the event, providing views of the different phases of the eclipse along with updates from observers in the field.
Unlike solar eclipses, where specialized eyewear is essential, viewing a total lunar eclipse poses no risk to eyesight. Observers can comfortably use telescopes, binoculars, or simply watch with the naked eye.
Photography enthusiasts looking to capture this remarkable event can refer to guides on lunar eclipse photography to enhance their experience. Those who wish to share their images can submit photos and comments to Space.com for a chance to be featured.
As the anticipation builds for this extraordinary event, the total lunar eclipse on September 7-8, 2025 promises to be a memorable occasion for astronomy lovers worldwide.
