Stargazers in North and South America will be able to view a red-colored “blood moon” starting Thursday night in the first total lunar eclipse visible on the continents since 2022.
The celestial event, observable with the naked eye, will have more than an hour of totality and can additionally be seen in parts of western Europe and Africa, as well as New Zealand.
A lunar eclipse occurs when the Earth goes between the moon and the sun, casting the Earth’s shadow on the moon.
A rare total lunar eclipse involves the Earth’s umbra, the darkest part of the planet’s shadow, covering the moon.
According to NASA, this type of eclipse can also be called a “blood moon” due to the reddish-orange color the moon can become during totality.
