shortly after 3:00 AM (GMT-3) The last lunar eclipse of this year began, Caused by one of the most fascinating natural phenomena in astronomy Its total duration is estimated to be at least six hours.,

celestial event This is a privilege that can only be viewed live from the Americas, the Pacific Ocean, and the eastern tip of Asia.

it is expected that About three hours after its onset, the planetary alignment reaches its maximum point., causes the so-called “blood moon”.

This celestial phenomenon is one of the most captivating for fans of the night sky. by coincidence With a full moon, our satellite is very close to the Sun in the sky passing through the southern part of the earth’s shadow starring Almost total lunar eclipse.

This is India‘s longest partial lunar eclipse 580 years, With a duration of just over 6 hours, and your way through the darkest part of Earth’s shadow will last about 3 hours, 28 minutes and 23 seconds, as reported by NASA.

It is expected that its most intense Earth’s shadow covers 97.4% of the Moon, experts are needed It will be like a total eclipse. In between, it will enter its maximum phase and in this example The surface of the Moon will be painted, to our sight, red, which is known as “full moon”, an event that This has already happened in May of this year.

At 6.02 UTC (tomorrow 3.02 Argentinian time), a partial shadow of the Earth will begin to fall in the upper left of the Moon, but a slight darkening of the Moon will not be observed until Earth’s full shadow begins to fall on the Moon’s top at 7.18 UTC (4.18 Argentine Time).

round earth shadow arc Will extend beyond the Moon until the peak of the eclipse at 9.02 UTC, when more than 97% of the Moon is in complete shadow And only a small stripe to the left of the Moon will shine in Earth’s partial shadow, NASA reports.

After the peak of the eclipse, Earth’s full shadow will gradually move from the Moon to the lower right, emerging completely from full shadow at 10:47 UTC, After this, it will be difficult to notice the Moon’s brightness when leaving Earth’s partial shadow, especially since morning twilight will begin at 10.54 UTC. The Moon will be completely out of Earth’s partial shadow at 12:03 UTC.

what is lunar eclipse

NS The Moon orbits the Earth approximately once every 29 and a half days. as it revolves around the planet Its changing position with respect to the Sun causes our natural satellite to go through several phases.

These steps are known as New moon, crescent, first quarter, crescent gibbous, full moon, diminishing gibbous, last quarter, old crescent and then the so-called new moon.

a lunar eclipse It occurs when the Sun, Earth and satellites align in the sky, in our eyes. Then, The moon crosses the shadow of our planet, Which is divided into two parts, the central, called the garbha, and the outer, known as the penumbra. Moon Full comes out in the evening and is visible throughout the night. Ultimately it sets just as the sun rises. It is not a unique feature in any other phase. According to NASA, This is because the Moon is exactly opposite the Sun in the sky when the Moon is full.

An eclipse can occur only at a full moon, and only if it passes through some part of the Earth’s shadow, whether it is a shadow or an outer, as well as a threshold or inner shadow. In this context, there are There are three basic types of lunar eclipses: one of luna penumbral that pierces the outer shadow, partial mole that pierces the inner shadow, and total moon which crosses the threshold and is a vibrant red colour.

Why does the moon turn blood red?

As the Moon moves fully toward the umbra, something interesting happens: The Moon begins to turn an orange-reddish hue. The reason for this incident? Earth’s atmosphere. As sunlight passes through it, the tiny molecules that make up our atmosphere scatter blue light, by what does sky blue look like, It leaves behind most of the red light that is bent or refracted towards the Earth’s shadow. We can see red light during an eclipse when it falls on the Moon in Earth’s shadow. This same effect gives sunrise and sunset a reddish-orange hue.

A variety of factors affect the appearance of the Moon during a total lunar eclipse. Clouds, dust, ash, photochemical droplets and organic matter in the atmosphere can change the amount of light refracted toward the womb. Also, the lunar eclipse of 2021 will take place along with the full moon. This means that it is further in the shadow of the womb and therefore may appear darker. The potential for variation provides a great opportunity for students to observe and evaluate a lunar eclipse on the basis of its brightness.

How and where can the longest partial lunar eclipse of the century and the end of the year be seen?
The lunar eclipse of 2021 will coincide with the full moon. This means that it is further in the shadow of the womb and therefore may appear darker.

Why is this eclipse so long?

This is a long eclipse for two main reasons: 1) the Moon’s orbital motion and 2) the nearly entirety of the eclipse.

First, the Moon’s orbit around the Earth is not a perfect circle and is out of center within the Earth’s orbit, so sometimes the Moon is closer to Earth and sometimes more distant. This change in distance affects the orbital speed of the Moon. Closer to Earth, the Moon moves faster, while farther away, it moves slower. Right now, the Moon is near its farthest point in its orbit around Earth and is therefore moving slowly through Earth’s shadow.

Second, since this eclipse is almost complete, The Moon spends more time in Earth’s umbra than a “more partial” eclipse.

To observe the incident, No special equipment, binoculars or glasses are needed. It is recommended to be able to appreciate it better Avoid light pollution in cities and look for obvious pollution. For those who can’t see it, Griffith Observatory in Los Angeles will feature time-lapse video of the eclipse, weather permitting, on your youtube page,
