Prepare for the Spectacular Blood Moon Total Lunar Eclipse
Stargazers worldwide are gearing up for a stunning celestial event as a total lunar eclipse, commonly referred to as a “blood moon,” is set to occur on September 7-8, 2025. During this phenomenon, Earth’s shadow will completely cover the moon, casting it in a striking red hue. This rare alignment of the Earth, moon, and sun will provide a breathtaking sight for millions.
A total lunar eclipse occurs when Earth passes directly between the moon and the sun, blocking sunlight and casting its shadow on the lunar surface. Although the moon’s tilted orbit means total lunar eclipses do not happen every month, approximately three times a year, the necessary alignment takes place, allowing for these spectacular events.
As the eclipse approaches, enthusiasts are encouraged to identify their ideal viewing locations. This preparation offers photographers a chance to capture stunning images of the eclipsed moon against iconic landmarks. Observers can also ensure that their views are unobstructed by buildings or other structures.
During the totality phase of the eclipse, which will last for approximately 82 minutes, the moon will take on a deep red color known as a “blood moon.” This effect results from Rayleigh scattering, where shorter blue wavelengths of light are scattered by particles in Earth’s atmosphere, allowing the longer red wavelengths to pass through unfettered. As a result, the moon becomes saturated with red light, creating a mesmerizing visual spectacle.
For those concerned about cloud cover or the moon being below the horizon during the eclipse, Space.com will provide a livestream of the event, complete with updates and views of different phases as they unfold. This will allow viewers to follow along, even if they cannot see the moon directly.
The total lunar eclipse will begin globally at 11:28 a.m. (1528 GMT) on September 7, with totality occurring at 1:30 p.m. ET (1730 GMT). Each phase of the eclipse will occur simultaneously for all observers, although visibility will depend on the moon’s position in the sky.
An estimated 5.8 billion people, or roughly 76% of the global population, situated across regions in Australia, Asia, Africa, and eastern Europe, will have the opportunity to witness the entire eclipse from start to finish. In contrast, viewers in countries such as the United Kingdom, Spain, and Brazil will see only partial phases. Unfortunately, observers in the Americas will miss the event entirely, as the moon will be below the horizon throughout the eclipse.
Unlike solar eclipses, which require protective eyewear to observe safely, viewing a total lunar eclipse poses no risk to eyesight. Observers can enjoy the event using telescopes, binoculars, or simply with the naked eye.
For those looking to capture the moment, guides on photographing lunar eclipses are available, offering tips for using a DSLR camera and recommendations for the best equipment for astrophotography in 2025.
As the date approaches, enthusiasts are encouraged to share their photos and experiences of the total lunar eclipse with Space.com by sending images, comments, and location details to [email protected]. This is an opportunity to connect with a global community of stargazers and share in the wonder of this extraordinary astronomical event.
