Sunlight scattered around the edges of the planet’s atmosphere will fall on the Moon and give it a distinct red-orange glow.
NASA explained: “The air molecules from Earth’s atmosphere scatter out most of the blue light.
“The remaining light reflects onto the Moon’s surface with a red glow, making the Moon appear red in the night sky.”
What time is the Blood Moon this week?
The eclipse will begin early on Wednesday but, unfortunately, will not be visible from the UK.
You will be able to see the Supermoon from just about anywhere on the globe but according to NASA, “the lunar eclipse is harder to catch”.
The space agency said: “The total eclipse, or the time when the Moon is in deepest shadow, will last for about 15 minutes.
“If the Moon is up in your area while this happens, you are in for a treat.”
