Longest Lunar Eclipse of 21st century due this month

Longest Lunar Eclipse of 21st century due this month

Hold your horoscope readings close to your chest and have your telescopes at the ready-later this month, we're set to witness the longest lunar eclipse of this century.

Two events will take place on July 27th, a total lunar eclipse when the Moon will be illuminated in red, an effect caused by the Sun's rays as they pass through the Earth's atmosphere and reflects off of it. On July 27, a lunar eclipse will be fully visible for 1 hour and 43 minutes. Those in South America, Europe, Africa, Asia and Australia can catch the view. Following this, the eclipse will fall below the horizon.

This was the reason a totally eclipsed Moon, at times, was called as Blood Moon. Solar eclipses are typically only seen by a small selection of the earth's population because the shadow cast by the moon is comparatively smaller than that cast by the earth.

The total lunar eclipse comes months after the world got a glimpse of a total lunar eclipse in January.

"Viewers in India are lucky since the eclipse, both partial and the total will be entirely visible from all parts of the country", he was quoted as saying. But when a full moon is wedged directly between the sun and the Earth in a total lunar eclipse, the moon falls directly into the Earth's shadow. The totality, or when the earth's shadow covers the moon and creates complete darkness, will last one hour and 43 minutes.

Lunar Eclipse: During this event, the full Moon will pass through the Earth's shadow (or umbra) lasting around 6 hours and 14 minutes from beginning to end. According to NASA, on top of the reddish tint given to the moon from the eclipse, the moon was also very close to earth's orbit, making it appear larger and brighter. A blue moon is second full moon amid a calendar month.

How to observe: Dubai Astronomy Group CEO Hasan Ahmad Al Hariri informed that lunar eclipses are visible from anywhere on Earth where it is nighttime.

"No special filters are required to protect your eyes like those used for 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.

Explaining the celestial phenomenon, Duari said a lunar eclipse takes place only at full moon.

Those with the best views will be able to see the lunar eclipse at key moments - when earth's shadow begins to cover the moon, when the moon turns red, and when the shadow begins to recede, all of which will happen over a period of four hours.
