On November 19, 2021 the Moon will cross through Earth's shadow over the course of there and a half hours creating a near total lunar eclipse. At the moment of maximum eclipse, at around 9:03 UTC (4:03 EST/1:03 PST), 99.1% of the Moon's disk will be within the Earth's umbra. It will be visible in all of North America, as well as large parts of South America, Polynesia, eastern Australia, and northeastern Asia.
Lunar eclipses occur when the sun, Earth, and moon line up and the Earth’s shadow is cast on the moon’s disk. During totality or near totality as in this eclipse, the moon passes through the dark shadow cone of the Earth, known as the umbra and blushes a shade of orange-red. This stunning coloration occur as sunlight travels through Earth’s own dust filled air, resulting in the Moon glowing reddish – the same reason we see the sun turn red during sunsets. The Moon's color can vary significantly from one eclipse to the next and its exact color can vary from one eclipse to the next depending on the amount of particles in our planet’s atmosphere.
