The longest total lunar eclipse of the 21st century will make our satellite blush on Friday, while the planet Mars, almost as close to Earth as possible, will be full of brilliance: a conjunction of phenomena that should delight amateur astronomers.
The show can be seen with the naked eye, without any danger contrary to solar eclipses. Binoculars, glbades and telescopes will allow you to enjoy even more. The eclipse, which corresponds to the moment when the Moon plunges into the shadow of the Earth, will be visible, partially or totally, in one half of the world. It can be observed from Africa, Europe, Asia, Australia. But it is East and South Africa, the Middle East and India that will be the best to enjoy the show. Europe will see the end of the eclipse
This Friday, the lunar eclipse, the longest of the century, will be observable from Europe, Asia, Africa and South America. In France, if the sky is clear, it promises a beautiful show of March aligned with the moon. ???????????? #Eclipse Of Moon #EclipseLunar pic.twitter.com/pSz051b4Ia

"The Moon should take on a reddish hue, a little coppery and Mars, nicknamed the red planet, will be next, very bright, with a slightly orange tint, "said Pascal Descamps, astronomer at the Observatory of Paris-PSL.
For a lunar eclipse to occur there must be an almost perfect alignment of the Sun, the Earth and the Moon. Our planet, lying between our star and the Moon, then projects its shadow on its natural satellite. The moon, full, will gradually return to the shadows, then in the shadows to be totally in the shade, before gradually emerging.
The complete phenomenon will begin at 19:14 and end at 1:28. The show will begin at 8:24 pm, the Moon giving the impression of being nibbled by the shadow. The most interesting moment of the eclipse, when the Moon will be completely in the shadow cone projected by the Earth, will start at 21:30 French time and will end at 23:13. This phase of "totality" will last 1 hour 43 minutes (103 minutes), making it the longest lunar eclipse of the 21st century.
"Sacred Trouble"
It s' is the second total lunar eclipse of 2018, the first one taking place on January 31 (it was not visible in Europe). Deprived of the rays of the Sun, the Moon will darken and take on a brick tint because the Earth's atmosphere deflects the red rays of sunlight into the shadow cone. The Moon can then send them back.
It is possible that the brightness of the moon is attenuated because "it will go through the center of the shadow of the Earth, where there is the least refracted light", warns Olivier Sanguy, of the Cité de l'Espace in Toulouse. The other heroine of the night will be Mars, which will be only 57.6 million kilometers from Earth. It will be necessary to wait until 2035 to see the red planet again so closely.
With the naked eye, we will see a brilliant point but with a telescope or a telescope, it will be possible to observe it in the details. The evening will give the opportunity to twist a rumor relayed on social networks that Mars would appear as big as the Moon this Friday. "If it were true, we would be in a lot of trouble, given the gravitational force," NASA quipped on its website.
Animations will take place everywhere in the countries concerned by the eclipse. In France, the French Association of Astronomy (AFA) organizes animations in 150 places. The Paris City Hall invites fans to visit the forecourt of the Sacred Heart to look at the sky. The Cité de l'Espace in Toulouse awaits a thousand people. In Madrid, the mayor proposes to watch the eclipse in the vast park of Pradolongo, against the backdrop of electronic music. (afp / nxp)
