The total lunar eclipse will last for a whopping one hour and 43 minutes starting at 20:21pm this evening.
The Moon will turn an eerie shade of red as it passes between the Earth and the sun blocking out sunlight.
Dr Helen Klus from the Royal Astronomical Society told BBC’s Today programme Mars Jupiter and Saturn will all be visible shortly after the rare ‘Blood Moon’.
The BBC host said he believed Mars and Jupiter would also be “on show tonight” shortly after the historical eclipse.
Ms Klus said: “Yes, and Saturn. It’s going to be really cool.
“Mars is going to look the best. It is going to look really bright and red because Mars is really close right now compared to what it usually is.
“It’s going to look a lot brighter and a lot redder. Mars is going to rise just under the Moon about half-an-hour later – so definitely keep an eye out for that.
“Saturn is going to be just to the south of the Moon and Jupiter will be just to the south of that and they will all be quite visible and bright as well.”
Stargazers hoping to catch a glimpse of the longest total lunar eclipse of the 21st Century should get a view from Europe, Asia, Africa, Australia and New Zealand.
Astrophysics professor Tim O’Brien said: “You need to have a clear south-eastern horizon as the moon comes up so we low-down in the south-east.
“As it rises, you’ll see it more and more clearly and then the eclipse finishes at about a quarter past 10pm.
“It’s just lit by the light that’s filtered through the Earth’s atmosphere which is why it looks this sort of dusty red.”
In the UK, the beginning of the eclipse will not be visible as it will be below the horizon, but the maximum eclipse through to the end of the eclipse will be visible from 9.21pm BST.
Nigeria, Congo, Angola and Morocco will be able to see the Blood Moon from 8.30pm local time.
Germany, Spain, France, Italy, Egypt, South Africa and Austria will all be able to witness the whole of the Blood Moon from 9.30pm local time.
Unfortunately Canada, Greenland and North and South America will not be able to witness the Blood Moon as it will not be in the right position.
The next total lunar eclipse will take place on January 21 2019.
