The entire eclipse of the moon will be on the night of January 20th

Residents of America, a lot of Europe and West Africa, will be able to observe the complete eclipse of the Moon on January 20 or 21, depending on the location of the last of its kind until 2021.

For northern and southern America, the whole eclipse will appear at the beginning of the 20th or early morning, while for Europe and Africa it will be seen shortly before sunrise on the 21st. The next exit from the planet of the phenomenon will be little visible because it will be more day.

The whole month will be in the shadow of the Earth between 03:34 and 06:51 GMT. During the first hour, it will slowly "hook" to the left. Eclipse will take a total hour from 04h41 GMT, according to NASA timetables.

The total eclipse phase will be three quarters less than the time of the Great Eclipse in July 2018, which will continue to be the longest of the 21st century.

During a complete eclipse, the Earth's natural Earth will not be invisible, but it will be red. It is because the sun's rays do not reach you directly, and instead a small part of the red rays will pass through the atmosphere of the Earth and break through the Moon.

"It's the last chance to realize the complete eclipse of the Moon," said Bruce Betts, chief scientist of the planetary society, the American astronomical organization.

Until 2021

Another complete eclipse will be in May 2021. Earlier, another partial eclipse will take place.

The total lunar eclipse can appear twice or three times a year. They occur when the Earth is placed exactly between the Sun and the Moon.

It is necessary for the sky to be clear to observe it. Often the clouds save the show.

Astronomers will be able to compare small variations of the moon's red tone this time. "Everything depends on what's in the atmosphere," says Bruce Betts.

"As the sun changes colors from one day to the next, the eclipse varies with particles in the atmosphere or, for example, with a volcanic eruption."

No telescope is needed to satisfy the eclipse. To see the craters of the Moon, the planetologist remembers that just a simple telescope is enough.
