Astronomy lovers in America, get ready for a treat! In the early morning of March 14, a total lunar eclipse will be visible across the US. This type of eclipse happens when Earth blocks the light from the sun that normally illuminates the moon, resulting in it appearing deep red, as if it were covered in blood.
On the night of March 13 and the early morning of the 14th, the darkest part of Earth’s shadow, called the umbra, will cover the moon during its fullest phase. Lunar eclipses when the moon is partially lit are relatively common—but those that coincide with a full moon are a relative rarity. On average, each region of Earth has the chance to view a total lunar eclipse only once every 2.5 years.
A second total lunar eclipse will happen this year on September 7 and will be visible in eastern parts of Africa, across much of Asia, and the western half of Australia.

The moon appears red during a lunar eclipse because of how the sun’s light interacts with Earth’s atmosphere. Visible sunlight appears white, but it is actually made up of a combination of lights of different colors, which can be refracted or scattered depending on how much of the atmosphere they have to travel through. It is for this reason that the sky appears blue when the sun is high in the sky but is often red at sunset, when the sun is low and its light is traveling longer distances through the atmosphere.
When sunlight hits Earth’s atmosphere during a lunar eclipse, light frequencies toward the blue end of the visible spectrum are scattered outward, away from Earth’s umbra, but those with longer wavelengths, toward the red part of the spectrum, are bent inward and cast onto the moon.
What Time Will the Lunar Eclipse Happen?
According to NASA, the eclipse will begin at 8:57 pm Pacific Time. In Mexico, the phenomenon will start at 10:57 pm CDT, in Argentina at 12:57 am (ART), and in Spain at 5:57 am (CET). The advance of Earth’s shadow across the moon will be slow. Observers will notice that the satellite will gradually lose illumination in the lead-up to the total eclipse, before turning blood red. The totality of the eclipse, or the time when the blood moon appears, is projected to happen at 11:26 pm PDT. The climax will last approximately one hour.
Here is a list of the times for the start of totality for other countries in the Americas:
- Mexico: 1:26 am
- Colombia: 1:26 am
- Chile: 3:26 am
- Argentina: 3:26 am
- Peru: 1:26 am
