Different parts across the globe will be witnessing longest total lunar eclipse of this century on 27th of this month. NASA has reported that it is likely to be the longest event from now till year 2123. Sources claim that during the total lunar eclipse, the Earth casts a reddish-orange shadow on the Moon’s surface. Hence, total lunar eclipse is termed as a “Blood Moon”.
According to astronomers, a total lunar eclipse takes place when Sun, Earth, and Moon are in a same line and are observed in perfect alignment with each other.
The U.S. space agency has declared that the total lunar eclipse will last for nearly 1 hour and 43 minutes. This eclipse is just four minutes shorter as compared to longest recorded eclipse on Earth, which was witnessed on July 16, 2000, and nearly lasted a little more than an hour and forty-six minutes. For the record, the total lunar eclipse that occurred on January 31, 2018, lasted for nearly 1 hour and 16 minutes.
The total lunar eclipse is projected to be visible across various parts of South America, Asia, Africa, and Middle East regions. However, the U.S. residents will be unable to view the lunar eclipse, but people populating most regions of Eastern Hemisphere will be able to witness it partially.
NASA has proclaimed that the next total lunar eclipse is likely to be observed in January next year and people of Europe and Americas can observe it.
Scientists have put forward myriad observations related to the total lunar eclipse. As per one such observation, during the total lunar eclipse, Earth totally blocks direct sunlight from reaching the surface of the Moon with the only light that is reflected from the surface of the Moon being refracted from Earth’s atmosphere. This results in sunlight appearing reddish in color on the totally eclipsed Moon’s surface.
