The total eclipse of Luna the longest of the 21st century will blush the satellite of the Earth Friday, while March which will be almost At its closest point to the blue planet, it will be particularly brilliant.
"It is an unusual and interesting coincidence of phenomena," he told AFP Pascal Descamps, astronomer of the Institute of Celestial Mechanics and Ephemeris Calculus (IMCCE ) of the Paris Observatory
"The Moon will have a reddish hue, slightly coppery, and March nicknamed" the red planet ", will be at his side very bright, with a slight orange tone The astronomical spectacle can be observed with the naked eye, without danger, but the binoculars, the lenses and the telescopes will make it even more enjoyable.
The eclipse will be visible only partially or totally in half of the world: we can see it from Africa, Europe, Asia and Australia.The best placed to take advantage of the show will be the inhabitants of Africa, the Middle East and India.
For that a lunar eclipse occur, there must be an almost perfect alignment of the Sun, the Earth and Luna . When our planet is between the star and the moon, it casts its shadow on our natural satellite.
On Friday, the Luna which will be in full moon, will gradually enter the gloom, then in the shadow, in which it will enter completely and will 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 6:24 pm GMT, when it will appear that the Moon has a sting of shadows.
The most captivating moment of eclipses that is to say, when the Moon will be completely in the shadow cone projected by the Earth will begin 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 lunar eclipse longer than 21st century.
"My niluna"
"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] ", notes 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 grand.
On Friday, on the other hand, will be a "miniluna" because it will be almost in the farthest point of the Earth and it will give the feeling of having a plus size small. Also, for this you will need more time to cross the cone in the shade.
Deprived of the sun's rays, the moon will darken and become red. This color is explained by the fact that the Earth's atmosphere deflects the sun's red rays into the shadow cone, and Luna can reflect them.
Depending on atmospheric conditions and, especially, pollution, the moon can acquire a very dark reddish gray, or a more intense red if there are no particles in the atmosphere.
The other protagonist of the night will be the planet March which it will be only 57.6 million kilometers from Earth (the minimum distance will be reached on July 31. )
The appearance of its diameter has not been as great for 15 years. And we will have to wait until 2035 to see so close to the red planet
At the naked eye we will only see a bright spot, but with lenses or a telescope it will be possible to observe it in detail
