1South Africa to view longest eclipse in a century

The moon will turn a stunning blood red this Friday for the longest total lunar eclipse this century lasting almost two hours.

A Lunar Eclipse is a phenomena that occurs when Earth comes between Moon and the Sun, thus obscuring Moon in its shadow.

A total lunar eclipse typically occurs once or twice a year and the next will take place on the night of January 21, 2019. The good part is that for viewers in India, both partial and total eclipses will be visible in its entirety from all parts of the country.

The July 27 eclipse will last for 1 hour and 43 minutes, which is very close to the theoretical maximum of 1 hour and 47 minutes.

The eclipse won't be visible from North America, Noah Petro, a scientist for the NASA Goddard Space Flight Center, told ABC News.

If you were on the moon when the total eclipse occurs, you would see a red ring around the Earth. Remember a lunar eclipse is when the Earth's shadow blocks the sun's light from reflecting off the moon. This will persist until 2.43 am, after which the Moon will begin to move outside the Earth's shadow.

But why does the moon turn red? Putting to rest all apprehensions about the risks associated with viewing the eclipse with a naked eye, Duari said, "No special filters are required to protect our eyes like those used for watching solar eclipses".

He said: "As the eclipse continues, it will be at peak position at 9.50pm and end at 10.13pm making it 35 minutes long".

Stages and time of the lunar eclipse that will be visible in Singapore on July 28, 2018. July's blood moon will start Friday, and southern Asia, the Indian Ocean region, Africa and the Middle East will be able to get a glimpse of it.

So if you are Brittany or Normandy don't get your hopes up.

What time will you be able to see it?

The last time the Red Planet was bigger and brighter than this was in 2003, when the distance between Mars and the Earth closed to less than 56 million kilometres.

Although the longest eclipse, Dr Sarun said the red moon will be smaller than usual because it will be at the farthest point from the Earth this year - at 406,086 kilometre from the Earth.

When will we see the lunar eclipse? .
