What is a total lunar eclipse?
Lunar eclipses happen during full moons, NASA tells us. They occur when Earth lines up exactly between the Sun and the Moon, its shadow falls on the Moon, making it look darker and sometimes giving it a dramatic red glow for a few hours.
During a total lunar eclipse, as the Moon moves into the central part of Earth’s shadow, known as the umbra, some sunlight still reaches its surface after passing through Earth’s atmosphere. Shorter wavelengths like blue and violet will scatter (i.e., light being redirected as it passes through the atmosphere), while longer wavelengths (red and orange colors) make it through. That's why the Moon appears red in color during a total lunar eclipse, according to NASA.
At any one time, a lunar eclipse can be seen from about half of the planet. This eclipse will be happening during the daytime in North and South America, so it won't be visible to that side of the world.
When is the next full moon?
