'Blood moon' to appear for 21st century's longest lunar eclipse on Friday

'Blood moon' to appear for 21st century's longest lunar eclipse on Friday

National forecaster Meteo France forecasts clear skies in the east, with patchy light cloud over much of the rest of the country allowing eclipse watchers to get a good view of the celestial event, in which the moon will turn blood red.

Every time there is an eclipse, the moon passes through the Earth's shadow, but it doesn't always pass through the same part of the shadow. And it's considered a "micro moon", though that isn't an official astronomical designation.

The next total lunar eclipse will take place on Jan 21, 2019, but it won't be visible from Singapore as it will happen during daytime.

"In early days experiencing a total lunar eclipse would have felt like the end of the world".

A total eclipse of the Moon will occur on Friday 27 July 2018.

It's also expected that Mars will be shining its brightest in 15 years.

During the Mars opposition, Mars will be about five times brighter than usual!

According to QCH experts lunar eclipses can be seen with naked eye unlike solar eclipses, which need to be looked at using eclipse glass or filters. It should also be at least partially visible from Europe, Australia, South America and most of eastern Asia, although the total eclipse phase will not last as long.

Head media and corporate communications of the Agency, Dr. Felix Ale, told The Guardian: "The Eclipse in Nigeria will start around 6:44pm as partial eclipse and developed into a total eclipse around 7:30pm". Eclipse in various phases begins at 10.45 PM on 27th July 2018 and ends at 4.59 AM on 28th July 2018.

On July 27, the world will witness the lunar event of the century as the sun, moon and earth prepare to align in a ideal line for an hour and 43 minutes. This lunar eclipse will be a dark one.

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

"Hence the appellation of "Blood Moon".

Lunar eclipses can only occur during a full moon when the sun fully illuminates the surface.

And finally - the Moon is near apogee (the most distant point in its orbit) around the July full moon, Edberg said. Earth's Umbra (a shadow's dark core) is responsible for a total lunar eclipse.

Not all of Australia will be able to see it however, as those over on the east coast will not see the Moon progress out of its shadow.

"Sometimes, the moon passes through the lighter part of Earth's shadow, causing a penumbral eclipse and total eclipse occur when the Earth completely block Sun rays from reaching the moon", he said.
