If you’re a fan of stargazing, make sure you have Friday morning marked down in your diary.
A rare blood moon is set to grace the skies over the UK – and you don’t want to miss it.
The moon will appear to glow bright red as Earth’s shadow crosses the lunar surface, known as a lunar eclipse.
Best of all, you won’t need any special equipment whatsoever to see it for yourself.
While people in North and South America will get the best views of the eclipse, British space fans should still be able to catch a glimpse in the early morning.
The moon will start to enter Earth’s shadow at 03:57 GMT with totality lasting from 06:26 until 07:31 GMT.
Professor Don Pollacco, an astronomer from the University of Warwick, says: ‘While this eclipse is best seen from the other side of the Atlantic, observers on the western side of the UK will see the total phase start before morning twilight at about 4 am when the Moon is low in the western sky.’
Here’s how you can see the incredible lunar event.
This week, millions of Britons will be able to see an ominous event light up the sky as a rare blood moon rises. Pictured: A blood moon over Florence, Arizona, in 2022
The blood moon, or lunar eclipse, will start from 06:26 GMT and continue until 07:31 GMT. British stargazers should be able to catch a glimpse of the eclipse in the early morning
How to see the Blood Moon
A lunar eclipse, or blood moon, is a great way to get started with amateur astronomy since you don’t need any equipment or specialist knowledge to see it.
All you need to do is look for the moon at the right time to see the moment it passes into the Earth’s shadow.
Shannon Schmoll, director of Abrams Planetarium at Michigan State University, says: ‘As long as the sky is clear, you should be able to see it.’
In the UK, the moon will enter totality close to dawn as the moon is setting which could make observation a bit more difficult.
However, with the right timing, that could give you an even more impressive view.
Professor Pollacco says: ‘The best time to see the eclipse will be sometime after 5 am and before the sky gets too bright.
‘The full moon often looks larger when near the horizon, so this eclipse could look impressive.’
Those in the west of the UK will see the eclipse from about 4:00am and will be able to watch as the moon turns red in Earth’s shadow. However, the East of the country won’t be under the path of the eclipse so they will only see about 90 per cent coverage
Although the moon won’t actually be any larger, our brains experience something called the Moon Illusion which causes the moon to appear bigger when it is near the horizon.
Despite this optical illusion having been known for thousands of years, scientists still aren’t sure why or how it works.
Luckily for British skygazers, the lunar eclipse will occur when the moon is very low in the sky so it should appear even more impressive than usual.
To ensure you get a good view, find an area with a good view of the horizon to the west where the sun will be setting.
Since the moon will be bright and it will be close to dawn, getting away from light pollution isn’t much of a concern.
But, if you can, getting away from bright streetlights and letting your eyes adjust to the dim light conditions will help you see more details of the lunar surface.
Unfortunately, the weather conditions for viewing the blood moon will not be ideal for most of the UK.
A Met Office spokesperson told MailOnline: ‘The current forecast for the lunar eclipse shows some cloud breaks on Friday night in parts of the UK, particularly in some western areas. Detail will become clearer as the week goes on, so keep an eye on our website or app for updates closer to the time.’
The eclipse will be best viewed over the USA where all states will be able to see the full lenght of totality. In the UK, the moon will be much lower on the horizon and the eclipse will occur closer to dawn
The Met Office weather forecast currently predicts clouds over much of the UK during the eclipse but there is a possibility of clearer skies especially in the West
What is a lunar eclipse?
Just like a solar eclipse, a lunar eclipse occurs when the moon passes into the shadow or ‘umbra’ cast by the Earth.
Professor Pollacco says: ‘The moon, like all planets, gives out no light of its own, but instead shines by reflecting sunlight.
‘On the morning of Friday 14th March, the moon during its monthly orbit of the Earth will pass through the Earth’s shadow.’
As this happens you will first see the edge of the Earth’s shadow pushing across the lunar surface, making it appear to vanish from our perspective.
But as the Earth’s shadow completely covers the moon during totality the moon will start to glow bright red.
This is because the Earth does not completely block out the light heading to the moon.
Instead, a small amount of light travels around the Earth through the atmosphere, reaching the moon and being bounced back to Earth from the lunar surface for our eyes to detect.
A blood moon occurs when the moon passes into the shadow, or umbra, cast by the Earth. Light from the sun then refracts through the Earth’s atmosphere and bounces of the moon
Since red light passes through the atmosphere more easily, the light which bounces back off the moon looks red. This is why the moon changes colour during an eclipse. Pictured: A lunar eclipse of Richmond, Virginia in 2022
Professor Pollacco says: ‘As the sunlight travels through our atmosphere on its way to the Moon the redder wavelengths pass through relatively unhindered while the bluer wavelengths are scattered by dust suspended in the earth’s atmosphere.
‘The red light reaches the moon and is then reflected back to us. So the redness of the moon actually tells us about the conditions in our atmosphere.’
This same phenomenon is why the sky appears blue, since only the blue wavelength light is scattered to become visible.
However, Britain is just on the edge of the eclipse path so only the West of the UK will be able to see the full spectacle.
Professor Pollacco adds: ‘From the rest of the UK the eclipse will not be total – the Moon will be greater than 90% obscured – but should still be a striking spectacle.’
However, there is no need to worry since lunar eclipses happen fairly regularly – occurring anywhere between four and seven times per year according to NASA.
If you do happen to miss this week’s eclipse the next chance will be on September 7 when a total lunar eclipse will sweep across parts of Asia, Africa, Australia and Europe.
Meanwhile, the United States will need to wait until March 2026 for the next chance to catch a total lunar eclipse.
The phases of the moon
Like Earth, the Moon has a day side and a night side, which change as the Moon rotates.
The Sun always illuminates half of the Moon while the other half remains dark, but how much we are able to see of that illuminated half changes as the Moon travels through its orbit.
In the Northern Hemisphere, the phases of the moon are:
1. New Moon
This is the invisible phase of the Moon, with the illuminated side of the Moon facing the Sun and the night side facing Earth.
2. Waxing crescent
This silver sliver of a Moon occurs when the illuminated half of the Moon faces mostly away from Earth, with only a tiny portion visible to us from our planet.
3. First Quarter
The Moon is now a quarter of the way through its monthly journey and you see half of its illuminated side.
4. Waxing Gibbous
Now most of the Moon’s dayside has come into view, and the Moon appears brighter in the sky.
5. Full Moon
This is as close as we come to seeing the Sun’s illumination of the entire day side of the Moon.
6. Waning Gibbous
As the Moon begins its journey back toward the Sun, the opposite side of the Moon now reflects the Moon’s light.
7. Last Quarter
The Moon looks like it’s half illuminated from the perspective of Earth, but really you’re seeing half of the half of the Moon that’s illuminated by the Sun ― or a quarter.
8. Waning Crescent
The Moon is nearly back to the point in its orbit where its dayside directly faces the Sun, and all that we see from our perspective is a thin curve.
