In a lunar eclipse, the Earth's shadow — called the umbra — blocks the sun's light from hitting the full moon, resulting in a dimmer moon with a distinct red and orange cast. It's also called a blood moon.

On March 13-14, 2025, a total lunar eclipse will be visible across Earth's night side. Although the point of greatest eclipse will be in the Pacific Ocean, North America and South America will get the best views. Some areas of Europe will get a slight view of the moonset, and East Asia will glimpse the spectacle at moonrise.

NASA has explained what a lunar eclipse is, where and how to watch it, what stages to expect, and the scientific reason behind the Moon's reddish color.
