Mexico, (Notimex) .- The total lunar eclipse of tomorrow, July 27, will be the longest of the 21st century with a duration of 103 minutes in its entirety phase, and it It is important to know the reasons for this peculiarity if all these phenomena occur in the same way.
In this type of event, the Earth interposes between the Moon which must be in its "full" phase and the Sun, so that the natural satellite fades a little. just as the shadow of the "blue planet" covers it.
This Friday we will see a blush in the moon, because the sun's rays pass through the Earth's atmosphere, says the head of the Astronomy and Science Zone Luis Enrique Erro, Wilder Chicana Nuncebay
"What we actually see in the color of the moon has to do with some of the pollution of the Earth's atmosphere," he said. Notimex, the astronomer He explained that the duration of an eclipse depends essentially on the relationship between the distances and the alignment of the three participants: Earth, Sun and Moon.
According to the date, he says, the Moon will be at the greatest distance from the Earth, and that in turn will be from the Sun. This makes the Earth's shadow, which is the one that really hits the moon, is vast and, being so large, the time that the moon has to move
This type of event is possible because any large object projects two types of shadows, the threshold and the gloominess; the first is solid, while the second is slender and broad.
"There are really two shadow cones that throw the Earth on the Moon, when the Moon begins to enter the cone the outermost, that is to say the penumbra, it makes the first contact, here begins the penumbra phase of the eclipse, "says Nuncebay Chicana
.Fill to the area of gloom and begins to touch the phase of the shadow, the party the darker, it is here where a reddish color is projected on the satellite, a stage that is known as partial.
"When the whole moon is introduced in the shade, we say that we are in the totality. So, the bigger the main shadow, the longer the total eclipse will last, "he said.
So, from the beginning of the eclipse to its end, It will take about six hours and as a reference, the physicist said that the Canary Islands phenomenon will begin at 18:18 and will end at midnight
This type of phenomenon also serves the scientific community to make observations and investigations with which they can get information on the atmosphere, the degree of contamination, and even on the ozone layer.
Because the total eclipse of the Moon can be observed in Mexico, the planetarium Luis Enrique Erro of the National Polytechnic Institute (IPN) plans to project a simulation of the eclipse for the general public as if seen from the Canary Islands, at the end of each of his short films that are exposed in its dome.
