A rare total lunar eclipse will appear in the night sky tomorrow (Tuesday, November 8).
Stargazers in four continents will have a chance to see the moon adopt a reddish hue as it moves into the Earth's shadow.
It's the last time the phenomenon - often known as a 'Blood Moon' - will be visible from Earth for almost two and a half years, with the next one not scheduled to appear until March 14, 2025, according to NASA.
Unfortunately, the rare sighting won't be visible all over the world. Only those in North and Central America, Asia, Australia the Pacific Islands, and parts of South America will have a chance to see the moon change color.
For a total lunar eclipse to occur, the moon, Earth, and Sun have to align perfectly, with the Earth in the middle and the moon in its shadow.
When this happens, the Earth's atmosphere scatters light from the sun which means that the face of the moon appears red rather than its usual milky white hue.
Before the moon turns red, there will be a period during which it dims and darkens. It will then enter the darkest part of the Earth's shadow - the umbra - and assume a reddish tone for a period of time known as totality.
In the United States, the phenomenon will begin early tomorrow morning when the moon will begin to enter the outer part of the Earth's shadow at 3:02AM Easter Daylight Time.
The partial eclipse will progress over the next few hours. During this period, the part of the moon that has already moved into the umbra will appear very dark. According to NASA, this will leave the impression that a bite has been taken out of the moon.
Then, around 5:17AM, totality will begin and the moon will appear red. This fascinating celestial show will last until around 6:42AM, when the moon will begin to move back out of the umbra.
Only those in Hawaii and Alaska will have the chance to see the total eclipse in its entirety. In other locations, the moon will not have risen or will already have set before the eclipse has started, or before it is completely over.
That said, those hoping to catch a glimpse of the blood moon won't have to worry about damaging their eyes. Unlike with solar eclipses, lunar eclipses are safe to view with the naked eye; NASA even encourages people to use binoculars and telescopes to get a better view of the phenomenon.
"Binoculars or a telescope will enhance the view and the red color. A dark environment away from bright lights makes for the best viewing conditions," the space agency's website reads.
