Kolkata: The longest total lunar eclipse of this century would be visible from all parts of India on July 27th. The celestial body would also be tinged with a reddish hue, a phenomenon popularly called "blood moon". Debiprosad Duari told the PTI news agency: "The viewers in India are lucky because the eclipse, partial and total, will be fully visible from all parts of the planet. the country. "
The eclipse would also be visible in parts of South America, much of Africa, the Middle East, and Central Asia," he said.
The total lunar eclipse would last one hour and 43 minutes while the partial eclipses, which would precede and follow the total eclipse, would last more than an hour, he said.
The partial lunar eclipse would begin at 23:54 Indian local time on July 27 and the total eclipse would begin at 1 am on July 28, said Duari.
The scientist has says that at 1.52 in the morning on July 28, the moon would look the darkest and that it would continue until 2:43.
"After this period, the moon will remain partially overshadowed until 3:49 am on July 28th. It will be a golden opportunity for celestial enthusiasts in India because the eclipse will be visible almost all night, "he said.
During the total lunar eclipse of July 27, the moon must cross the central part of the Earth's shadow.
But on the 27th of July late at night, the Full Moon would be near its apogee, the farthest point of the Earth in its orbit around the Earth, and it would be the smallest full moon of the year.
"This smaller and slower full moon takes longer to traverse the Earth 's shadow than a full moon. which is closer to Earth and moving faster into orbit.Why a full moon at or near the lunar climax adds up duration of a total lunar eclipse, "Duari said.
The full moon would plunge deep into the shadow of the Earth in the night of July 27 to 28 when the distance from the Moon to the Earth just before the eclipse would be about 406,223 kilometers , he said.
During a total lunar eclipse, the disc of the moon can take a very colorful appearance from bright orange to blood red and more rarely from dark brown to very dark gray, depending on which part of the shadow from the Earth that he would cross.
That was the reason why a moon totally overshadowed, sometimes, was called Blood Moon.
Explaining the celestial phenomenon, Duari says that a lunar eclipse only occurs at the full moon.
"Whenever the Sun, the Earth and the Moon arrive in a perfect straight line, when the rays of the Sun fall on the Earth, the Earth's shadow falls on a space, and only when the Moon enters in this area of darkness we see a lunar eclipse. "Describing 2018, as a year of lunar eclipses, Duari said that the last total lunar eclipse took place earlier this year January 31.
"It was widely known as the Super Blue Blood Moon because it was a so-called supermoon, when a moon appears extra wide and bright being the most close to the Earth in its elliptical orbit. the calendar month, "he said.
" The next total lunar eclipse of January 21, 2019 will only last an hour and two minutes because it will pbad north of the center of the city. " 39, shadow, "added Duari.
To observe lunar eclipses at the naked eye, Duari said," No special filters are required to protect our eyes, like those used to observe the solar eclipses: one does not need a telescope to observe the eclipse, but a good pair of binoculars will improve experience. "
