Longest total lunar eclipse of this century will grace the night sky on 27th of this month.

The US space research institute NASA says the lunar eclipse will last for 1 hour and 43 minutes with total viability in Eastern Africa and Central Asia.

Residents in other parts of Africa and Asia as well those in Europe, Australia and South America will be able to see a partial lunar eclipse.

Skywatchers in North America will not be able to see the rare event and will have to wait until 2020 to experience a total lunar eclipse.

During a lunar eclipse, the moon appears to be red because it lines up perfectly with the Earth and sun such that the Earth’s shadow totally blocks the sun’s light.

Scientists say the reason this lunar eclipse is especially long is because the moon is passing almost directly through the central part of Earth's shadow.
