"Supermoon of blood": What you need to know about the rare and "triple" phenomenon that will take place this week

On the night of next January 20th, a complete eclipse of the Moon will take place, which "paints" our natural red satellite, giving way to the so-called "supercup of blood."

This is a combination of three astronomical events simultaneously: full lunar eclipse, "moon of blood" and "supermon". This is a rare phenomenon this happens when our planet falls between the Sun and the Moon, and the satellite is in the darkest dark area on Earth.

According to Walter Freeman, a physicist at the University of Syracuse (USA), this phenomenon will last about three hours. "First, a normal full moon will be observed at about 22:35 (on the east coast of the US). At this point, the Earth's shadow will begin to pass before the Moon, preventing almost all sunlight reaching it, the viewers will see that the moon it seems he is gradually "swallowed" bottom to left. This process will end at 23:40, when the Earth's shadow will cover the entire lunar surface. This is the beginning of a complete blurring. "Then the moon will again be lit again by the Sun, and at 1:45 January 21, it will be fully visible again.

How often does this type of eclipse happen?

Freeman says that on average there is "a little less" the total lunar eclipse per year. – Eclipse of the moon this can happen only during the full moonwhen the satellite is on the opposite side of the earth (…) But the orbit of the Moon is tilted slightly compared to the Earth, so when the moon is full, the shadow of our planet passes a little above and below it, so we do not have a lunar eclipse every month, – he added.

What is the difference between the total lunar eclipse and the "blood of the month"?

During the general lunar eclipse, the Moon does not do this will be "totally invisible", "The time of sunlight is refracted by the atmosphere of the Earth and reaches the moon, bending the edges of the Earth, this small amount of red light illuminates the moon is enough for us, but instead of being bright and white, He will be very dull and red, more or less 10,000 times thinner than usual, for what is called a "moon of blood", – explained the physicist at the University of Syracuse.

"Since the Moon does not shine on its own, but only reflects sunlight, any lunar eclipse occurs when the Earth is between the Sun and the Moon," he continued.

What steps should be taken to observe the total lunar eclipse?

According to Freeman, do not take any precautions when observing the lunar eclipse, because the moon is not bright enough to negatively affect the eyes, as in the case of a solar eclipse. The "Moon of Blood" is one of the few opportunities that we must see Moon and stars in the sky at the same time, because the Moon is usually too bright. "

When will the next full lunar eclipse happen?

This astronomical event will repeat on May 26, 2021. But Walter Freeman said that in the United States, the following general lunar eclipse can be observed on November 8, 2022.
