Longest lunar eclipse of the century happening in July

Longest lunar eclipse of the century happening in July

Whenever the sun, earth and moon come in a ideal straight line, as the sun's rays falls on the earth, its shadow falls onto a patch of space, and only when, moon enters that patch of shadow can we see a lunar eclipse.

According to the Dubai Astronomy Group, the eclipse will last for about one hour and 43 minutes, the longest in the century, and will also feature a "blood moon". That means anyone who is on the side of the earth that is experiencing nighttime will be able to see the lunar eclipse whereas a solar eclipse can only be seen by the people who are where the moon's shadow falls. So, rather than darkened skies, viewers will be treated to a ruddy red visage that's often dubbed a "blood moon" (though the most finicky reserve this term for a series of four consecutive lunar eclipses).

The U.S. will miss out again with this upcoming celestial phenomenon, as it will be visible in one of the other five continents.

The phenomenon will also be visible in some parts of South America, large parts of Africa, Middle East and Central Asia.

For those outside the lunar eclipse's line of sight, the Virtual Telescope Project will be livestreaming the moon's descent into darkness beginning at 2:30 p.m. EDT. During those dates, it will be at its brightest in the sky and will even be visible to the naked eye.

A solar eclipse or Surya Grahan which is on July 13, 2018, comes nearly after 5 months after a partial solar eclipse was visible earlier in February.

In India, the partial eclipse will begin on July 13 at 07:18 am and the last location to see the partial eclipse would be at 08:13 am.

"The greatest eclipse, when moon will look the darkest, will be at around 01:52 am and the totality will continue at 02:43 am after this period the moon will remain partially eclipsed till 03:49 am of July 28", Duari said in a media release. This additionally makes it the longest time when an eclipse will be partially observable between the years 2011 and 2020.

If the entire Moon passes through the umbral shadow, then a total eclipse of the moon occurs. A blue moon is second full moon amid a calendar month. "Special filters are required to protect our eyes like those used for watching solar eclipses".

But on July 27 late night, the Full Moon would be near its apogee, the farthest point from the Earth in its orbit around the Earth, and it would be the smallest full moon of the year.

An eclipse of the moon takes place only at full moon.

The next time a lunar eclipse is visible in North America is January 21, 2019.
