The phenomenon, the longest of the 21st century, will be visible, partially or totally, only in Africa, Europe, Asia and Australia . And in Latin America, Brazil, Uruguay and Argentina.
The longest total solar eclipse of the 21st century will tinge the Earth's red satellite Friday, while Mars, which will be almost at its closest point "It's a rare and interesting coincidence of phenomena," told AFP Pascal Descamps, astronomer at the Institute of Celestial Mechanics and Ephemeris Calculus (IMCCE) of the Paris Observatory
. "The moon will have a reddish, slightly coppery tone, and Mars, nicknamed "the red planet", will be at his side very brightly, with a slightly orange tone, "he explains.
The astronomical spectacle can be observed at the naked eye no danger But binoculars, lenses and telescopes will make it even more enjoyable.
The eclipse will be visible only partially or totally in half the world: we can see it from Africa, from Europe , from Asia and Australia See also: This will be the longest total eclipse of e 21st century moon
The best placed to enjoy the show will be the inhabitants of Africa, the Middle East and India. 19659006] In Latin America, it will be visible at dusk Friday on the east coast of the continent, Brazil, Uruguay and Argentina, although the austral winter may complicate the observation of the phenomenon.
For an eclipse of the Moon to occur that there must be an almost perfect alignment of the Sun, the Earth and the Moon. When our planet is located between the star and the moon, it casts its shadow on our natural satellite.
Malta Fenzmer and Niclas Mortzek, PhD students at the Institute of Astrophysics at the University of Goettingen, are preparing a telescope with a 50 cm mirror for this Friday's eclipse.

On Friday, the moon, which will be in full moon, will gradually enter the dark, then in the shade, where it will enter fully and then come out gradually.
The complete phenomenon (including the penumbra phase) will begin at 17:14 GMT and will end at 23:28 GMT
The show will actually start at 1824 GMT, when it will appear that the Moon has a shadowing.
The most captivating moment of the eclipse is that when the Moon is completely in the shadow cone projected by the Earth, it will start at 19:30 GMT and will end at 21:13 GMT
This "total" phase will last 1 hour and 43 minutes (103 minutes), making it the longest lunar eclipse of the 21st century.

"
– "Miniluna" –
"It is a replica of the eclipse of July 16, 2000, which lasted 1 hour and 46 minutes, becoming the longest lunar eclipse of the 20th century [que terminó el 31 de diciembre del 2000] ", underlines Pascal Descamps
This will be the second total solar eclipse of 2018, after that of January 31st. On this occasion it was a "supermoon", because the satellite looked to be particularly big.
On Friday, on the other hand, will be a "miniluna" because it will be almost at the farthest point of the Earth and it will give the sensation of having a smaller size. Also for this it will take longer to cross the cone of the shadow.
Deprived of sun's rays, the moon will darken and become red. This color is explained by the fact that the Earth's atmosphere diverts the red rays from the sun into the shadow cone, and that the moon can reflect them.
Depending on atmospheric conditions and, especially, pollution, the moon can acquire a very dark reddish gray, or dye a more intense red if there are no particles in the atmosphere .
The other protagonist of the night will be the planet Mars, which will be only 57.6 million kilometers from Earth. (The minimum distance will be reached on July 31.)
Fifteen years ago, the appearance of its diameter is not so great. And we will have to wait until 2035 to see the red planet so close
At the naked eye, you will only see a bright spot, but with lenses or a telescope it will be possible to observe it in detail.
