The second and last lunar eclipse 2021 is taking place in Taurus on November 19. The lunar eclipse is a part of Astronomical Events. This lunar eclipse will be partially visible in the eastern part of India. According to astronomers, this is the longest partial lunar eclipse in 1000 years. Earlier on February 18, 1440, there was a partial lunar eclipse of such a long duration. According to Indian time, on October 19, the lunar eclipse 2021 India will start from 11:32 in the morning and end at 6.23 in the evening. Due to its partial sighting in India, its effects will not be valid. Let us now see what is a lunar eclipse scientifically and why does it happen?
Lunar Eclipse 2021 India
What Is Lunar Eclipse?
An eclipse occurs when the Moon, the Earth, and the Sun are in one line. When the Earth comes between the Sun and the Moon, the Moon, which receives light from the Sun, becomes obstructed and dark. When the Moon is not visible, it is called a lunar eclipse. A lunar eclipse occurs only on the full Moon. A lunar eclipse, whether complete or partial, occurs only when the Moon is full. There is no lunar eclipse on every full Moon, and similarly, there is no solar eclipse on every new Moon. Rahu and Ketu are behind this. Rahu-Ketu completes one cycle around the Earth in about 18.6 years, and their motion is in the opposite direction of the Sun and the Moon. On every full Moon and new Moon, the Moon does not align with the Sun and the Earth.
Reason for eclipse
An eclipse occurs when Rahu-Ketu and Sun are in almost the same direction from the Earth. If we consider that the axis of the Moon’s orbit around the Earth was always in the same direction, then eclipses would have occurred in particular months every year. It is also not because Rahu Ketu has revolved around the Earth for 18.6 years. Therefore, we can say that it is not necessary to have a new moon full moon for an eclipse, but Rahu and Ketu should also be in the direction of the Sun.
The people of our country knew about the eclipse from thousands of years ago. They had accurate information about the future eclipse. People used to bathe in the rivers during the eclipse. In the olden days, people were also worried about living. This belief persists in our society even today. Some say that there is going to be an eclipse today, do not leave the house. Some say that Rahu Ketu demons have eaten the Moon or the Sun, but wise people do not do this, and they are not worried about the eclipse. It would be appropriate to tell such people that whenever an eclipse occurs, the world’s scientists are anxious to see it.
Experiment
To understand the lunar eclipse properly, we can try an experiment. We know that a lunar eclipse (2021) occurs from the shadow of the Earth. The Moon revolves around the Earth at a speed of 321.68 km/h. The Moon sometimes comes in between the Sun and the Earth while orbiting. To know this, we keep a ball on a stool; we will consider it as Earth. Put a lamp on another stool whose light falls on the ball, and we will consider the lamp as the Sun. Another small ball is hung from a rope on the left side of the bigger ball. Now we see that the name of the light does not fall on the smaller ball because the bigger ball blocks the light coming from the lamp. Thus, when the Earth comes between the Moon and the Sun, a lunar eclipse occurs.
Eclipses are sometimes complete and sometimes part. The Full Moon Has Worshipped In India. A full moon eclipse occurs only when the Earth’s shadow completely covers the Moon. If only a part of the Moon is visible, then there is a partial lunar eclipse. Similarly, if the Moon completely covers the Sun, then there will be a total eclipse. If the Moon covers some part of the Sun, then a partial solar eclipse occurs. Lunar eclipse 2021 India is a partial eclipse.
