2 days ago, the total lunar eclipse will be the most complete for three consecutive years. The total phase of the eclipse has begun as the entire Moon is covered by the Earth’s shadow. This overall stage will end at 5.12 pm. while the partial stage of the eclipse will continue until 18.19.

About the Lunar Eclipse: The Moon revolves around the Earth in an orbit. In a similar period, the Earth revolves around the Sun. Sometimes the Earth also comes between the Sun and the Moon. When this happens, the Earth blocks the sunlight normally indicated by the Moon. It is the sunlight that makes the moon shine. Instead of light hitting the surface of the Moon, the Earth’s shadow sinks into the Moon. This is a lunar eclipse. A lunar eclipse can only occur when the moon is full.
The lunar eclipse can be seen from Earth at night. There are three types of lunar eclipses:
Total lunar eclipse.
Partial lunar eclipse
Daily lunar eclipse

A lunar eclipse begins when the Earth comes between the Sun and the Moon, partially or completely blocking sunlight from reaching the Moon. This casts a shadow on the Moon’s surface, which we see from Earth.

During a total solar eclipse, some sunlight will still reach the Moon. This light will also act through the Earth’s environment, where the blue light will be scattered along all paths due to a phenomenon called Rayleigh scattering. It also allows red light to pass through and be reflected off the Moon, causing it to appear red during an eclipse.

Under the Ministry of Earth Sciences, the entire eclipse stage will proceed during moonrise in myriad eastern parts of the nation, which include Kolkata and Guwahati. But for different cities like Delhi, Mumbai, Chennai and Bangalore, the whole would have stopped till the moonrise. The eclipse is currently not noticeable in India as it is still a day away, but you can watch it on the live stream below adequately.

The total lunar eclipse has now begun as the Moon is completely enveloped by the shadow cast by the Earth. As you can see, the Moon now looks pinker because the light pointing at it right now is sunlight that has passed through Earth’s climate.

The totality of a lunar eclipse, when Earth’s shadow completely encloses the Moon, will begin within minutes. Currently, as can be seen in the image below, it appears that part of the Moon is completely cloudy, but this is because the sharp reflection from the uncovered part washes out the covered part. According to NASA scientist Noah Pedro, this happens when we see the eclipse with our eyes because of the way our brain processes light.

But when a total lunar eclipse begins, the entire moon will be illuminated with a faint, reddening light. This is because some light from the Sun will still reach the Moon after Earth’s climate is activated. As this light penetrates the atmosphere, only then will the blue wavelengths be scattered all the way, allowing the reddening wavelengths of light to pass through.

Why don’t lunar eclipses happen all the time?

The Moon takes one full orbit around the Earth each month, rounding the Sun’s path during a new Moon and opposite the Sun’s path during a full moon. But if that’s the case, why don’t lunar eclipses happen twice every month?

This is because the Moon orbits the Earth in a circle that is slightly tilted, perturbing the Earth’s orbit around the Sun. But this inclination remains constant in comparison with the stars, meaning which changes in comparison with the Sun. This means that the Moon is in a direct position to cross Earth’s shadow about twice a year, resulting in a lunar eclipse.

How to see the eclipse

You don’t need any special equipment to see a lunar eclipse, but having binoculars or a telescope can give you a better impression of the Moon and its reddish shadow during the eclipse. Likewise, the best viewing conditions can be created in darker areas away from city lights. In the map below, you can see the parts of the globe from which distinct stages of the eclipse will be perceived. Colored patterns mark the edge of the perception nation for different stages.
