Red planet and ‘blood moon’ pair up to dazzle skygazers

The longest “blood moon” eclipse this century will coincide with Mars’ closest strategy in 15 years to supply skygazers an exciting astronomical double invoice on Friday, astronomers say.

For about half the world, the moon will likely be partly or absolutely in Earth’s shadow from 1714 to 2328 GMT — six hours and 14 minutes in all.

The interval of full eclipse — referred to as “totality”, when the moon seems darkest — will final from 1930 to 2113 GMT.

“Totality will last for 103 minutes, making it the longest eclipse of the 21st century!” mentioned the Royal Astronomical Society in London.

At the identical time, Mars will hover close to the moon within the night time sky, simply seen with the bare eye.

Our neighbouring planet will seem unusually massive and vibrant, a mere 57.7 million kilometres (35.9 million miles) from Earth on its elliptical orbit across the solar.

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

Amateur astronomers within the southern hemisphere will likely be best-placed to benefit from the spectacle, particularly these in southern Africa, Australia, India and Madagascar, although it can even be partly seen in Europe and South America.

– Celestial our bodies align –

A complete lunar eclipse occurs when Earth takes place in a straight line between the moon and solar, blotting out the direct daylight that usually makes our satellite tv for pc glow whitish-yellow.

The moon travels to an analogous place each month, however the tilt of its orbit means it usually passes above or under the Earth’s shadow — so most months now we have a full moon with out an eclipse.

When the three celestial our bodies are completely lined up, nevertheless, the Earth’s ambiance scatters blue gentle from the solar whereas refracting or bending crimson gentle onto the moon, normally giving it a rosy blush.

This is what offers the phenomenon the title “blood moon”, although Mark Bailey of the Armagh Observatory in Northern Ireland mentioned the color can fluctuate vastly.

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

“During a really darkish eclipse the moon could also be virtually invisible.

“Less dark eclipses may show the moon as dark grey or brown… as rust-coloured, brick-red, or, if very bright, copper-red or orange.”

The lengthy length of this eclipse is partly due to the truth that the moon will make a near-central passage by way of Earth’s umbra — the darkest, most central a part of the shadow.

– ‘Eerie and lovely’ –

Our fixed companion can even be on the farthest level on its orbit from Earth, making its motion throughout the sky slower from our perspective, thus spending longer in the dead of night.

NASA, in the meantime, has known as out social media hoaxers claiming that Mars will seem as huge because the moon throughout the eclipse.

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

Mars will extra possible seem as a really vibrant star, and viewers will want no protecting eye gear.

“All you have to do is dress warmly and go outside!” the Royal Astronomical Society advises.

“If you want a close-up view of the moon as it turns red, a pair of binoculars is helpful.”

“All eclipses are spectacular,” the society’s Robert Massey added.

“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 and I’ll certainly be looking out for it!”
