The super blood wolf moon will finally appear tonight after a lot of anticipation.
After this dazzling appearance, the next one won't happen until January 31, 2037, and it will be the third and last of the 21st century.
The rare astronomical display is a combination of a supermoon, and a lunar eclipse, and will see the moon turn a stunning shade of red.
Best of all, the event will be visible with the naked eye, meaning there’s no need to splash out on expensive equipment, the Mirror reports.
Here’s everything you need to know, including how and when to see to see the super blood wolf moon from the UK.
When is the super blood wolf moon?
The super blood wolf moon will appear in the early hours of Monday January 21.
For viewers in the UK, the best time to see it will be at around 5:15am GMT.
Meanwhile, for those of you in the Americas and northern and western Europe, the best time to see the super blood wolf moon will be just after 02:30am.
Better get that strong coffee at the ready!
How to see the super blood wolf moon
Try to head to an area with little light pollution - for example, away from the city and into the countryside.
If you can, head out early to let your eyes get used to the darkness.
The forecast in London is around 2 degrees Celsius, so remember to bring layers!
What is a super blood wolf moon?
A super blood wolf moon combines two events - a supermoon and a total lunar eclipse.
During a total lunar eclipse, the moon glows red, which is how the event gets the ‘blood’ in its name.
A total lunar eclipse occurs when Earth passes between the sun and moon, casting a shadow across the moon.
A spokesperson for NASA explained: “A total lunar eclipse occurs when the moon and the sun are on exact opposite sides of Earth. Although the moon is in Earth's shadow, some sunlight reaches the moon.
“The sunlight passes through Earth's atmosphere, which causes Earth’s atmosphere to filter out most of the blue light. This makes the moon appear red to people on Earth.”
Meanwhile, a supermoon occurs when a full moon occurs at or near the perigee - its closes point to Earth.
NASA explained: “Full moons can occur at any point along the Moon’s elliptical path, but when a full moon occurs at or near the perigee, it looks slightly larger and brighter than a typical full moon. That’s what the term ‘supermoon’ refers to.”
