[Ed. – If you’re following this, the “blood moon,” or lunar eclipse, will be the fourth in a relatively rare blood-moon tetrad. The last two blood-moon tetrads occurred in 1967 and 1948.]
According to NASA, all three events have lined up just five times since 1900, the last in 1982. And it won’t happen again until 2033.
The full eclipse of the moon will last more than an hour and be visible, weather permitting, starting at 10:11 p.m [Eastern time – Ed.].
The phenomenon will unfold as the moon, Earth and sun line up, with Earth’s shadow totally obscuring the moon and casting an eerie red shadow on the lunar surface.
Light refracted off of Earth’s atmosphere appears on the moon in a dark-red hue, leading to the term blood moon.
The total eclipse coincides with the full moon nearest the fall equinox, which is known as the harvest moon.
On top of that, the moon will be at its closest approach to Earth for the year, meaning it’s also a supermoon. And the moon will appear 13% larger to the naked eye, according to NASA.
