There's going to be a lunar eclipse this weekend, the first visible from the UK for three years.
These events - which happen twice every three years - allow stargazers to see a 'Blood Moon' which is when the moon turns red.
A total lunar eclipse is when the moon passes through the shadow of the earth, with the last one occurring in January 2019.
The Royal Observatory say that the there is a red colour because “it is illuminated by light that has passed through the Earth’s atmosphere and has been bent back towards the Moon by refraction”.
For this to happen, the moon, sun and earth have to be lined up perfectly, and the moon has to be directly in the earth's shadow, which is why they only happen every so often.
Those wanting to see the Blood Moon will want to know when it is taking place and how to watch it - so here is some key information.
When to watch
The Royal Observatory says the best time to watch the eclipse in the UK will be between 4.29am and 5.06am on Monday the 16th of may.
This is when the moon will be in earth's full shadow and will appear to be red for a short while.
Where to watch
The eclipse will be visible across the UK as well as other European countries, North and South America, and parts of Africa.
While there is the possibility you could see it from anywhere in the UK, keep an eye on the forecast as there may be certain parts of the country where the eclipse will be blocked by clouds.
What if it's cloudy?
If it is cloudy you will not be able to see the lunar eclipse in person, but you may still be able to watch the event live.
NASA plan to livestream the eclipse which will take place at 2.30am on their feed. The stream is scheduled to start on 15 May 2022.
Will you stay up to watch the blood moon? let us know in the comments.
