What is a total lunar eclipse? Blood moon and its meaning explainedSean KeachTechnology and Science – latest news | The Sun

A BLOOD Moon will appear over the weekend – but what is it?

Here’s a guide to the stunning space phenomenon known as a total lunar eclipse.

What is a lunar eclipse and when is the next one?

The Earth is constantly rotating around the Sun, and the Moon is constantly rotating around the Earth.

Sometimes all three can align, placing the Earth directly between the Sun and the Moon in a straight line.

It means the Moon is in the darkest part of Earth’s shadow – the “umbra”.

And due to convenient sizing and distancing of all three objects, no sunlight can directly reach the Moon.

However, some sunlight is refracted by Earth’s atmosphere, making the Moon appear reddish – hence the name “Blood Moon”.

Lunar eclipses typically last just a few hours, and can be viewed from anywhere on the night side of Earth.

Because they’re typically quite dim, it’s also possible to view lunar eclipses without eye protection, which isn’t the case with a solar eclipse.



There are three different types of lunar eclipse:

Total lunar eclipse – This is where the Moon turns deep red, receiving only light that’s passed through Earth’s atmosphere.

Penumbral lunar eclipse – This is when the Sun, Moon and Earth fail to form a perfect straight line, so the Moon only travels through the outer part of Earth’s shadow. This means the Moon’s surface is partly darkened.Partial lunar eclipse – This is when part of the Moon travels through Earth’s full shadow, which results in part of the Moon being darkened.

The next total lunar eclipse is on May 16, 2022, but it will begin on Sunday, May 15 for Americans.

Can you see the May 16, 2022 lunar eclipse in the UK and US?

The total lunar eclipse will be visible in the UK and US.

In fact, it will appear over most of North America, South America, and parts of Europe and Africa.


Americans on the East Coast will have the best chance to view the eclipse, but the totality will be visible across much of the USA.

Nasa has created a visibility map that you can see at the bottom of this article.

What time is the May 16, 2022 lunar eclipse?

In the UK, the Moon will begin entering the Earth’s shadow at around 2.30am on May 16.

And the total eclipse will occur at about 4.30am.

It will finally come to an end at 7.50am – but the eclipse will have stopped being visible about two-and-a-half hours before then, as the Moon sets below the horizon at 5.10am.

For Americans, the Earth’s shadow will start to cover the Moon at 10.28pm Eastern Time on May 15.


Then the total eclipse will begin at 11.29pm the same day.

The peak of the eclipse will be at 12.11am on May 16.

And the totality will last until 12:53am.

Here are the best Blood Moons to look out for up until 2030, according to Nasa:

The 2025, 2026, 2028 and 2029 total lunar eclipses won’t qualify as super moons.
