Stargazers across a swathe of the world marvelled at a dramatic red “Blood Moon” during a rare total lunar eclipse in the early hours of Friday morning.

The celestial spectacle was visible in the Americas and Pacific and Atlantic oceans, as well as in the westernmost parts of Europe and Africa.

The phenomenon happens when the Sun, Earth and Moon line up, causing our planet to cast a giant shadow across its satellite.

But as the Earth’s shadow crept across the Moon, it did not entirely blot out its white glow — instead the Moon glowed a reddish colour.

This is because the only sunlight that reaches the Moon is “bent and scattered” as it goes through Earth’s atmosphere, said Daniel Brown, an astronomer at Britain’s Nottingham Trent University.

It is similar to how the light can become pink or red during sunrises or sunsets on Earth, he added.

The more clouds and dust there are in Earth’s atmosphere, the redder the Moon appears.

Brown called the lunar eclipse, which will last around six hours, “an amazing way to see the solar system in action.”

The period when the Moon is completely in Earth’s shadow — called the totality — lasts just over an hour.

This event has been dubbed the “Blood Worm Moon,” after one of the names given to March full moons by some Native Americans.

‘Inspire us’

In North America, the moon started to look like a bite was being taken out of it from 1:09 a.m. Eastern Time (0509 GMT), with the totality from 2:26 a.m. to 3:31 a.m., according to NASA.

In France, the totality is from 7:26 am to 8:31 a.m. local time (0626-0731 GMT), according to the French Institute of Celestial Mechanics and Ephemeris Calculation.

Only the most western parts of Europe, such as France’s Brittany region, will get any chance to see the totality before the Moon sets.

People in New Zealand have the opposite problem, with the eclipse only partially visible as the Moon rose.

Brown dislikes the term “Blood Moon”, saying it has a negative connotation and “originates from a misinformed theory of the end of the world.”

But not all societies took a negative view of these celestial shows.

Some people in Africa traditionally viewed a lunar eclipse as a conflict between the Sun and Moon that could be resolved by people “demonstrating on Earth how we work together” and laying old feuds aside, Brown said.

He called it “an amazing story that should inspire us all.”

Solar eclipse soon

It is the first total lunar eclipse since 2022, but there will be another one this September.

Thursday’s event is a “Micromoon”, meaning the Moon is the farthest away it gets from Earth, making it appear about seven percent smaller than normal, according to the website Earthsky.

This is the opposite of a “Supermoon”, as was seen during 2022’s lunar eclipse.

Some stargazers will be in for another treat later this month — a partial solar eclipse, which is when the Moon blocks out the Sun’s light on Earth.
