A total lunar eclipse will turn the moon red. Here's how to watch

The moon will glow a scarlet color during this year's first total lunar eclipse on Sunday

a stark contrast to its ordinarily milky white sheen.

A partial eclipse will begin at 10:27 p.m. ET Sunday, with the total lunar eclipse starting at 11:29 p.m. ET, according to EarthSky.

The total eclipse will end at 12:53 a.m. ET Monday, and the partial eclipse will end at 1:55 a.m. ET Monday,

A lunar eclipse occurs when the moon, Earth and sun fall into alignment

with the moon passing through Earth's shadow, according to NASA.

When the moon passes through the darkest part of the Earth's shadow, called the umbra

it's known as a total lunar eclipse, the space agency said.

When the sun's rays reach the Earth, much of the blue and green light is scattered

while the orange and red colors remain visible, which is why the moon turns a reddish hue and is often referred to as the "blood moon".

About two lunar eclipses occur each year, and the next will be a total lunar eclipse in November.
