On Sunday, September 27, much of the world will have a chance to witness a "supermoon lunar eclipse."
This super-rare event happens when a lunar eclipse occurs at the same time as a supermoon.
A supermoon is a full moon that occurs when the Moon is closest to Earth.
A luner eclipse happens when Earth gets inbetween the Sun and the Moon, blocking direct light. This gives the moon a reddish hue.
The last time both of these events happened at the same time was 1982, when Game of Thrones star Natalie Dormer may have looked a lot different:

According to NASA: "Earth’s shadow will begin to dim the supermoon slightly beginning at 8:11 p.m. EDT. A noticeable shadow will begin to fall on the moon at 9:07 p.m., and the total eclipse will start at 10:11 p.m."
The total eclipse will last one hour and 12 minutes, says NASA, and will be visible to North and South America, Europe, Africa, and parts of West Asia and the eastern Pacific.
