ELINFORMADOR.COM.VE.- The longest total solar eclipse of the 21st century will dye the Earth's red satellite Friday, while Mars, which will be almost at its closest point to the blue planet " It is an unusual and interesting coincidence of phenomena, "said Pascal Descamps, an astronomer at the Institute of Celestial Mechanics and Ephemeris Calculus (IMCCE) of AFP. Observatory of Paris
. it will have a reddish tone, a little coppery, and Mars, nicknamed "the red planet", will be at his side very bright, with a slightly orange tone, "he explains
The astronomical spectacle can be observed at Naked eye, without danger. But binoculars, lenses and telescopes will make it even more enjoyable.
The eclipse will be visible only partially or totally in the middle of the world: it can be seen from Africa, Europe, Asia and Australia
of the exhibition will be the inhabitants of Africa, the Middle East and India.
In Latin America, it will be visible at dusk Friday on the east coast of the continent, Brazil, Uruguay and Argentina. phenomenon
For an eclipse of the Moon to occur, 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.
On Friday, the moon, which will be in full moon, will gradually enter the dark, then in the dark, in the night. It will enter completely 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 Luna has a shadow stitch
The most captivating moment of the eclipse, that is to say when the Moon will be completely in the shadow cone projected by the Earth, 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" –
"This is a replica of the Eclipse of July 16, 2000, which lasted 1 hour and 46 minutes, becoming the longest lunar eclipse of the twentieth century [que terminó el 31 de diciembre del 2000] ", explains Pascal Descamps.
This will be the second total solar eclipse of 2018, after the one that took place on 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 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 sunlight, 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, above all, pollution, the moon you can acquire a very dark reddish gray, or dye a more intense red if there are no particles in it. 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.)
There At fifteen, 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 first glance, you will see only a bright spot, but with lenses or a telescope, it will be possible to observe it in detail
