Lunar Eclipse 2021 LIVE: Beaver ‘blood’ full moon will be longest eclipse in 580 years

According to some Christians, the Bible predicts that a series blood moons has already heralded the end of the world in 2014-15.

John Hagee, a Texas megachurch pastor in Texas, was among several evangelical leaders to assign eschatological significance to a sequence of four lunar eclipses within 18 months, known to astronomers as a tetrad, that all coincided with Jewish holidays.

Mr Hagee linked that event to passages in the Old Testament’s Book of Joel and the New Testament’s Book of Acts, which promise that “the sun shall be turned into darkness, and the moon into blood”.

“I believe that the heavens are God’s billboard; that he has been sending signals to Planet Earth but we just have not been picking them up,” said Mr Hagee in a sermon.

However, tetrads are not particularly rare, with eight scheduled to occur between 2015 and 2100. Nor is it unusual for lunar eclipses to fall on a Jewish festival, since the Jewish calendar is a lunar calendar and Passover is always a full moon.

According to Earth and Sky magazine, these two things have combined eight times since the start of the Gregorian calendar in 0 AD. The 20th century saw two tetrads falling on Jewish festivals, in 1949-50 and 1967-68.

Throughout history, humans have come up with stories to explain why blood moons happen, with many attributing malice to the event.

The Inca supposedly believed that a celestial jaguar was attacking and trying to eat the moon, so they would shake spears and make noise at it to drive it away. Or so at least claimed the Spanish colonists – not exactly an unjaundiced source.

In ancient Mesopotamia, the blood moon was thought to represent a cosmic attack on the king. Like a modern-day dictator using lookalikes to dodge assassination, they would put a surrogate king in place ahead of time while the real king pretended to be an ordinary citizen.

Others have a kinder view. One myth among the Batammaliba people of Togo and Benin says that lunar eclipses are a time of conflict between the sun and the moon, and that humans must encourage the pair to resolve their differences by settling our own disputes on Earth.

Another story told by the Luiseño tribe of Native Americans, from what is now California, is that the moon is sick and humans must sing chants and prayers to help it get well.

Here is the full schedule for the eclipse for key time zones where it will be visible, according to former Nasa astrophysicist and eclipse photographer Fred Espenak.

First will come the opening of the eclipse, during which the Earth’s shadow slowly falls over the moon. That will begin at:

• UK (UTC-0): 7.18am
• Eastern US (UTC-5): 2.18am
• US west coast (UTC-8): 11.18pm
• New Zealand (UTC+13): 8.18pm
• Eastern Australia (UTC+11): 6.18pm
• West Australia and China (UTC+8): 3:18pm

Then there will be a moment where the eclipse is at its fullest:

• UK: 9.02am to 9.03am
• Eastern US: 4.02am to 4.03am
• US west coast: 1.02am to 1.03am
• New Zealand: 10.02 pm to 10.03pm
• Eastern Australia: 8.02pm to 8.03pm
• West Australia and China: 5.02pm to 5.03pm

Finally the eclipse will wane and the shadow will pass, ending at:

• UK: 10.47am
• Eastern US: 5.47am
• US west coast: 2.47am
• New Zealand: 11.47pm
• Eastern Australia: 9.47pm
• West Australia and China: 6.47pm

An effect known as Rayleigh Scattering means the Moon will appear red during the lunar eclipse.

It’s all to do with the way the light as to pass through the Earth’s atmosphere before it reaches the Moon on the other side of the Sun, similar to the way the sky changes colour during the sunrise and sunset. It has earned November’s full moon the double moniker of Beaver and Blood.

For almost three and a half hours on 18 and 19 November, sky-watchers in North America, South America, East Asia and Australasia will see the moon turn red.

So what actually is a blood moon? And what makes it red? All your questions answered…

The lunar eclipse will be visible across large parts of the Earth, with those in North and South America best placed to view it.

This excellent eclipse map from TimeAndDate shows how it will pass from Western Europe and Africa, right across the Americas, before finishing up in East Asia and Australasia. As you can see, the UK is only just in the eclipse path, and it won’t be there for long before the Sun swallows it up.

Tonight’s lunar eclipse will actually begin early tomorrow morning, starting at 7.18am GMT on 19 November, and will last for more than six hours.

The actual peak of the eclipse, which starts at 9.02am, will last for 3 hours and 28 minutes.

With the sunrise in the UK taking place at 7,26am on Friday, the lunar eclipse will not be visible for long. In the US, however, it will be visible for its entirety, weather permitting.
