Lunar eclipse is one of the most interesting astronomical phenomena. At that time, we will admire the unique and rare views of the Moon, especially the super blood moon eclipse. Here, let’s find out more information about this extremely interesting lunar eclipse.
What is a lunar eclipse? Causes of lunar eclipse
A lunar eclipse is an astronomical phenomenon related to the positions of the Moon, Sun, and Earth . When they do, they will line up or roughly align with each other, with the Earth in the middle.
A lunar eclipse occurs when the Moon, Earth, and Sun are aligned
The Moon will enter the Earth’s shadow pyramid and be completely or partially obscured by the Earth from the Sun’s light.
As we all know, the Moon does not naturally glow, it always reflects the light of the Sun. When the light of the Sun reaching the Moon is blocked by the Earth, the Moon will gradually darken and create a lunar eclipse.

When will the 2022 lunar eclipse happen?
From now until the end of 2022 , the world will still witness the last lunar eclipse of the year on November 8, 2022. This total lunar eclipse will likely be visible in locations such as parts of Asia, Australia, North America, parts of North and Eastern Europe, the North Pole and most of South America.

In Vietnam, this astronomical event will also be seen with the naked eye if the sky is clear and cloudy without the need for supporting tools.
Classification of lunar eclipses
Total lunar eclipse
This is a phenomenon that occurs when the Moon enters the dark side of the Earth , also known as the blood moon phenomenon . The light from the Moon will be dimmed and only visible red or dark orange because the Earth’s atmosphere has blocked all short-wavelength rays from the Sun, only red and orange wavelengths. down to the Moon
Total lunar eclipse
Partial lunar eclipse
A partial lunar eclipse occurs when the Moon, Earth, and Sun are almost in a straight line. The light of the Moon will be dimmed and lost due to being obscured. The Earth’s shadow will be red or black, blocking the light from the Sun to the Moon . It usually occurs before or after a total lunar eclipse.
Partial lunar eclipse
Midnight lunar eclipse
This is what happens when the Moon enters the Earth’s umbra . At this time , the light of the Moon will dim and gradually darken . This phenomenon is difficult to see with the naked eye and requires tools to assist.

What effect does a lunar eclipse have on the Earth?
The Earth is always under the gravitational pull of the Moon and the Sun. Normally, because they are often deflected from each other, the gravitational forces from the Moon and the Sun do not often act on the Earth at the same time. But when a lunar eclipse occurs, the gravitational force on Earth will be maximum due to the total force acting at the same time .
This will cause the tides on Earth to be stronger and higher than usual . They can cause some geological oscillations.
Lunar eclipse makes the tides stronger and higher
As for humans, according to experts, this phenomenon will cause melatonin and hormones in the body related to sleep and wake cycles to decrease . Therefore on these days, people will find it more difficult to sleep . However, this phenomenon does not affect too much health. There are also statistics that say lunar eclipses increase the fertility rate of women, but this is not confirmed.

How to see lunar eclipse
You can fully see the total and partial lunar eclipse with the naked eye if the location you are tracking is in the visible area and the sky is clear. However, to see more clearly, you can use binoculars or a telescope.
As for the penumbral lunar eclipse , you cannot observe it with the naked eye, so you need the support of astronomical devices.

Frequently asked questions about lunar eclipses
How are lunar eclipses and solar eclipses different?
It can be said that lunar eclipse and solar eclipse are two astronomical phenomena that occur when the Moon, Sun and Earth are aligned with each other . However, a solar eclipse occurs when the Moon is between the Sun and the Earth, making the Earth unable to receive light from the Sun during the day because it is blocked by the Moon.
Lunar eclipse and solar eclipse
Meanwhile, a lunar eclipse occurs because the Earth is between the Moon and the Sun. The Moon does not receive light from the Sun because it is obscured by the Earth. Lunar eclipses occur less during the year, only about 1-2 times , but are easy to see in a wide range. Solar eclipses can appear 2-5 times a year but can only be seen at a very narrow point.

Does the lunar eclipse happen during the day or at night?
A lunar eclipse can only occur at night , only then can the Moon be seen dark and dim because the Earth blocks the light from the Sun.
Lunar eclipse takes place at night
When does the longest lunar eclipse of the 21st century take place?
The longest lunar eclipse of the 21st century is a partial lunar eclipse that will take place on November 19, 2021 , lasting for more than 3 hours . In Vietnam, the lunar eclipse peaks at 16:03 and can be observed from 17:01 when the moon rises.

When does a super blood moon eclipse happen?
A super blood moon eclipse is a combination of two supermoons and blood moons when occurring at the same time during a lunar eclipse. “Blood Moon” refers to the total lunar eclipse. At this time the moon will be red or dark orange like blood.
Lunar eclipse super blood moon
Meanwhile, supermoon refers to the phenomenon when the Moon will pass through the perigee (the point closest to Earth), then we will see it larger than normal. Super blood moon phenomenon is a rare phenomenon that is not easy to see because the probability of these two phenomena occurring is very low.

Why do lunar eclipses often occur on the full moon day?
Lunar eclipses usually occur on full moon days, because only at this time the Moon, Sun and Earth can be in a row . And then the Earth has the ability to block the light from the Sun reaching the Moon.
