A total lunar eclipse will happen on July 27, triggering what is known as a Blood Moon as it happens.
A Blood Moon is when the Moon takes on a reddish tinge during the eclipse, due to the way light is filtered.
Known as Rayleigh scattering, indirect sunlight reaching the Moon during the total eclipse is filtered, leaving the violet colour spectrum out of the light.
This leaves reddish toned light to reach the Moon’s surface, giving it its sinister red glow.
The second blood Moon of the year, a once in a lifetime lunar event occurred on January 31, meaning a Super Blue Blood Moon was seen by stargazers.
A Supermoon is seen when a new full Moon appears during its closest distance from the Earth, making the Moon seem larger than usual.
A Blue Moon is when two full Moons have appeared within the same calendar month, and these events all coincided for one amazing lunar phenomenon.
Unfortunately, those in the UK did not witness the Super Blue Blood Moon in January, due to the positioning warranting Western Europe, Africa and Central and Southern America unable to see the Moon.
This Blood Moon will be the longest eclipse of the century, as the Moon will remain in shadow for 103 minutes.
Taking six hours and 14 minutes from start to finish, the Moon will be passing through the Earth’s shadow at its furthest point from Earth, which is why the eclipse will last for so long.
How to watch the Blood Moon
Luckily for stargazers in the UK, July 27’s Blood Moon will be visible in the sky during its total eclipse.
Celestial expert Bruce McClure said the Eastern Hemisphere will have the best view of the lunar event.
“This lunar eclipse is primarily visible from the world’s Eastern Hemisphere – Europe, Africa, Asia, Australia and New Zealand.
“South America, at least in part, can watch the final stages of the eclipse just after sunset July 27, whereas New Zealand will catch the beginning stages of the eclipse before sunrise July 28.
“North America, most of the Arctic and much of the Pacific Ocean will miss out entirely.
“The greatest eclipse takes place at or around midnight for Madagascar and the Middle East.”
In the UK the Moon will not be visible at the beginning of its eclipse, however, the maximum eclipse will be visible at 9.21pm (BST).
Here are all the timings and directions for the Blood Moon in BST:
8.50pm – Moonrise (Southeast horizon)
9.21pm – Maximum eclipse (very low in the southeast): the Moon will be closest to the centre of the Earth’s shadow.
10.13pm – Total eclipse ends (Low in the southeast): the Moon will begin to leave the shadow of the Earth and will be in partial shadow.
11.19pm – Partial eclipse ends (Low in the southeast): The Moon has left the shadow and no longer appears red.
12.28am – The eclipse ends (Fairly high in the south): The Moon will have left the Earth’s shadow completely and will appear darker than usual.
