The longest lunar eclipse of the 21st century is coming on Friday

The partial eclipse of the Moon will begin at 23h 54m IST on July 27.

Social media is already flooded with excited Europeans exclaiming at the wondrous sight as the glow get brighter and redder ever night, as only red and yellow light can pass through the Earth's atmosphere.

The best regions for witnessing the spectacle in Europe are in southern Italy, the Balkans and in Eastern Europe, where the entire and partial phases of the eclipse will be visible, and only parts of the penumbral phase will be missed.

So where can you see the total lunar eclipse?

If you were standing on the moon at the time of the eclipse, the Earth would look like a black disk outlined in glowing red.

"They will move through reasonably quickly but if that coincides with the peak moment of the eclipse, they could obscure the moon".

But the eclipse that will stretch from South America to New Zealand on Friday will last nearly four hours, coming in at three hours and 55 minutes.

Although it is expected to last 103 minutes, those in the United Kingdom and Ireland will not be able to see the start of the lunar eclipse as the moon will still be below the horizon.

Lunar eclipses occur as the moon passes through Earth's shadow. The penumbra is the partial outer shadow, and the umbra is the full, dark shadow.

Why is it called Blood Moon? But there's nothing scary about it. The effect of the atmosphere is to bend the light from each celestial object by about half a degree, which also happens to be their apparent diameters in the sky. Blue light is scattered, leaving only red.

According to National Geographic, an Inca myth told the story of a jaguar that attacked and ate the moon (giving it its red colour). So it's anyone's guess just how red this eclipse will be.

Christie said the combination of all these events was interesting, but nonetheless all predictable under the laws of astronomy.

The period of complete eclipse - known as "totality", when the moon appears darkest - will last from 1930 to 2113 GMT.

But there are a couple of extra-special happenings that night. Opposition occurs when Earth is positioned with the Sun lined up directly behind it, and an outlying planet, such as Mars, Saturn, or Jupiter, lined up on the opposite side.

And finally - the Moon is near apogee (the most distant point in its orbit) around the July full moon, Edberg said. Astronomers often talk about these events, characterized by two celestial bodies appearing very close together in the sky.
