A total lunar eclipse occurs when the Earth passes directly between the Moon and the Sun, blocking out both. It means that light must pass through the Earth's atmosphere on its way to the Moon, turning it red.
The event will begin around 3:00 a.m. Eastern time, peak in a total eclipse three hours later, and then end three hours later. It will be seen in East Asia, Australia, the Pacific, and North America.
Lunar eclipses happen about once every year and a half. However, because of the timing, there will be no more chances to see a longer blood moon until March 14, 2025.
