A total lunar eclipse, often called a "Blood Moon," is a celestial event that is currently happening on September 7-8, 2025. It occurs when the Earth passes directly between the Sun and the Moon, casting its shadow on the lunar surface. The Moon doesn't disappear entirely during a total lunar eclipse; instead, it takes on a reddish or coppery hue. This "blood moon" effect is caused by a phenomenon called Rayleigh scattering, the same process that makes sunsets appear red. As sunlight travels through Earth's atmosphere, blue light is scattered away, while the longer-wavelength red and orange light passes through and is refracted onto the Moon's surface.
The lunar eclipse on September 7-8, 2025, is a significant event for several reasons:
Global Visibility: A large portion of the world's population, around 85%, has the opportunity to see at least part of the eclipse. It is most visible in its entirety across Asia, Western Australia, and parts of Europe and Africa. Viewers in North and South America will not be able to see the eclipse.
Long Duration: The total phase of this eclipse is expected to last for about 82 minutes, which is one of the longest total lunar eclipses in recent years. This provides an extended opportunity for observation and photography.
Safety: Unlike a solar eclipse, a lunar eclipse is completely safe to view with the naked eye. No special equipment or protective filters are necessary. You can also use binoculars or a telescope to get a closer look at the moon's surf
