Weeks after the world gazed at the moon blocking the sun in a rare partial solar eclipse that was visible from Earth, stargazers are in for another celestial dance. A Total Lunar Eclipse (TLE) will occur in the skies as Earth comes between the Sun and the Moon and its shadow covers the Moon.
It is a celestial phenomenon that happens right after a solar eclipse dazzles the skies. The total lunar eclipse happens at the full moon and is marked by a straight-line alignment of the Sun, Moon, and Earth. This phenomenon is known as syzygy, which in Greek means paired together.
What is Total Lunar Eclipse?
A lunar eclipse occurs when the Sun, Earth, and Moon align so that the Moon passes into Earth’s shadow. In a total lunar eclipse, the entire Moon falls within the darkest part of Earth’s shadow, called the umbra. Nearly 99.1% of the Moon’s disk will be within Earth’s umbra in this eclipse.
The Total Lunar Eclipse will give the Moon a blood-red appearance and so it is dubbed the Blood Moon. Nasa explains that since only sunlight reaching the Moon passes through Earth’s atmosphere, the dust or clouds give the eclipse a reddish appearance. As light travels in waves, different colors of light have different physical properties. It is the same phenomenon that makes our sky look blue.
The eclipse will cast a shadow on the Earth which is classified in three phases: Umbra, which is the darker, central part, the outer part known as Penumbra, and Antumbra, which is the partly shaded area beyond the umbra. The two prerequisites for a total lunar eclipse include a full moon and, at the same time, the moon should be a lunar node, so the Sun, the Moon, and the Earth are aligned perfectly together.
Why is this Total Lunar Eclipse unique?
The November 7 lunar eclipse will be unique since it will not happen again till 2025. The next Total Lunar Eclipse will only happen on September 7, 2025. The eclipse in 2025 will be visible in Europe, Asia, Australia, Africa, North America, East in South America, the Pacific, Atlantic, Indian Ocean, Arctic, and Antarctica.
Where will Total Lunar Eclipse be visible?
The eclipse will be visible in several parts of the world, including North/East Europe, Asia, Australia, North America, Much of South America, the Pacific, the Atlantic, the Indian Ocean, the Arctic, and Antarctica. While the eclipse will not be visible in India, some final fleeting moments could be seen in some parts of the country.
