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.

The next total lunar eclipse will be on Sept. 7-8, 2025, visible in parts of Asia and Australia, with totality lasting 82 minutes.

The next lunar eclipse will be a total lunar eclipse overnight on March 13-14, 2025. It is the first total lunar eclipse since November 2022. The total lunar eclipse will be visible over North America, and most of South America. During a total lunar eclipse, the moon will appear to take on a red hue, giving rise to the " Blood Moon ".
