Friday, July 27 the sky will return with a show: starting at 21.30 in fact we can admire the total eclipse of the longest Moon of the century.
One hour and 43 minutes in which the moon will be obscured by the Earth and will assume a red color.
The total lunar eclipse occurs in the presence of an alignment of the Sun, Earth and Moon; the Moon will also appear very small (as opposed to what happens with the so-called Superluna) because it will be at its maximum distance from the Earth.
Already at about 19.30 the Moon will begin to be partially obscured by the Earth, entering a phase of penumbra, while from 21.30 the eclipse will be total.
How can this be observed?
“Contrary to what usually happens with solar eclipse, the total eclipse of the Moon can be seen with the naked eye without any danger to the eyes,” reassured Professor Paolo Vinciguerra, director of Humanitas Ophthalmology Center and lecturer at Humanitas University.
“No special filters are needed to observe the total lunar eclipse because the reflected light of the Earth’s satellite contains no dangerous components for our eyes (ultraviolet, infrared and radio waves), as is the case with light emitted by the Sun,” continued the professor.
We must therefore only hope that the sky is clear to be able to better admire the total lunar eclipse and perhaps have good binoculars to observe the lunar craters as they reappear.
