IN PHOTOS: ‘Blood moon’ dazzles skygazers in century’s longest eclipse

PARIS, France – The longest “blood moon” eclipse this century was underway on Friday, July 27, (Saturday, July 28 in Philippine time) coinciding with Mars’ closest approach in 15 years to treat skygazers across the globe to a thrilling celestial spectacle.

As Earth’s constant companion slowly sailed across the skies, crowds gathered around the world to catch a glimpse of the rare phenomenon.

Beside Lake Magadi, 100 kilometers (60 miles) southwest of the Kenyan capital Nairobi, young members of the Maasai community watched the eclipse through a high-powered telescope provided by a local couple.

“Until today I thought Mars, Jupiter and the other planets were in the imagination of scientists,” Purity Sailepo, 16, told Agence France-Presse (AFP).

“But now I’ve seen it I can believe it and I want to be an astronomer to tell other people.”

Unlike with a solar eclipse, viewers do not need protective eye gear to observe the rare display. 

For about half the world, the moon will be partly or fully in Earth’s shadow from 1714 to 2328 GMT (1:14 am to 7:28 am Philippine time) – 6 hours and 14 minutes in all.

The period of complete eclipse – known as “totality”, when the moon appears darkest – lasted from 1930 to 2113 GMT (3:30 am to 5:13 am Philippine time).

At the same time, Mars hovered near the moon in the night sky, easily visible to the naked eye.

Amateur astronomers in the southern hemisphere are best-placed to witness the rare sight, especially in southern Africa, Australia, South Asia and Madagascar, though it will also be partly visible in Europe and South America.

More than 2,000 people including many children armed with binoculars gathered in the Tunisian capital of Tunis.

“I hope this eclipse will bring us happiness and peace,” said Karima, 46, without taking her eyes off the sky.

However, bad weather thwarted the cosmic display in several parts of the world. 

Widespread monsoon rainstorms and thick clouds hid the moon across much of India and its neighbors, which should have had a prime view.

Similarly, eager observers who had assembled on cliffs and beaches in the English county of Dorset were left in the dark due to an overcast sky.

“It’s disappointing,” Tish Adams, 67, told AFP. “I took a few photos but there was nothing but a streak of pink in the sky.”

Celestial bodies align

Mars appeared unusually large and bright, a mere 57.7 million kilometers (35.9 million miles) from Earth on its elliptical orbit around the sun.

“We have a rare and interesting conjunction of phenomena,” Pascal Descamps, an astronomer with the Paris Observatory, told AFP.

“We should have a coppery red tint on the moon with Mars the ‘Red Planet’ just next to it, very bright and with a slight orange hue itself.”

A total lunar eclipse happens when Earth takes position in a straight line between the moon and sun, blotting out the direct sunlight that normally makes our satellite glow whitish-yellow.

The moon travels to a similar position every month, but the tilt of its orbit means it normally passes above or below the Earth’s shadow – so most months we have a full moon without an eclipse.

When the 3 celestial bodies are perfectly lined up, however, the Earth’s atmosphere scatters blue light from the sun while refracting or bending red light onto the moon, usually giving it a rosy blush.

This is what gives the phenomenon the name “blood moon”, though Mark Bailey of the Armagh Observatory in Northern Ireland said the color can vary greatly.

It depends partly on “how cloudy or transparent those parts of the Earth’s atmosphere are which enable sunlight to reach the moon”, he told AFP.

“During a very dark eclipse the moon may be almost invisible.”

The long duration of this eclipse is partly due to the fact that the moon will make a near-central passage through Earth’s umbra – the darkest, most central part of the shadow.

‘Eerie and beautiful’

The moon will also be at the farthest point on its orbit from Earth, making its movement across the sky slower from our perspective, thus spending longer in the dark.

NASA, meanwhile, called out social media hoaxers claiming that Mars would appear as big as the moon during the eclipse.

“If that were true, we’d be in big trouble given the gravitational pulls on Earth, Mars, and our moon!” the NASA website stated.

Mars will more likely appear as a very bright star.

“In the middle of a lunar eclipse it can look as if a red planet has taken up residence near the Earth – they are both eerie and beautiful,” said Robert Massey of the Royal Astronomical Society in London. – Rappler.com
