A lunar eclipse happens when the sun, Earth and moon all align so that the moon passes into the Earth's shadow. During a total lunar eclipse, like the one happening this March, the entire moon will fall within the darkest part of Earth's shadow.
Each lunar eclipse is visible from half of Earth.
March's full moon, known as the Worm Moon, will pass into Earth's shadow on the night of March 13, or early on March 14, depending on the time zone, according to NASA. This eclipse will be visible from Earth's Western Hemisphere.
The Old Farmer's Almanac details specific moonrise times for ZIP codes across the U.S. Local forecasts also include detailed information on how clear the night sky will be in various locations.
