LAHORE – (DNA) – The lunar eclipse will last for one hour and 43 minutes with total viability in Eastern Africa and Central Asia on July 27.

According to the US space research institute NASA, 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 , reported a private tv news channel on Sunday.

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 that the moon is passing almost directly through the central part of Earth’s shadow.
