An unusual conjunction in the sky will dazzle astronomy enthusiasts on Friday: The total lunar eclipse the longest of the 21st century will dye our red satellite March almost at its closest point to Earth, will shine in all its splendor. In much of the world, the spectacle can be observed with the naked eye, without the need for protection, as happens with eclipses of the Sun.
"All they have to do is go out …"] Royal Astronomical Society of London. The eclipse, which corresponds to the moment when the Moon is submerged in the shadow of the Earth, can be seen totally or partially in half of the world: Africa, Europe, Asia and Australia. But it is to the east and south of Africa Middle East and India that the show will be best appreciated.
Track the phenomenon as a whole and from within, among others, the Institute of Astrophysics of the Canaries (Spanish archipelago in the Atlantic) will carry out a broadcast live from Namibia via the sky-live.tv channel in collaboration with the European project STARS4ALL and the HESS High Energy Observatory. In addition you will be able to see the video of the transmission in this note.
"Unusual and interesting"
"We have an unusual and interesting conjunction of phenomena. The Mon must be dyed red, a little coppery, and Mars said "red planet", will be at his side, very bright, with a slightly orange hue ", explains Pascal Descamps astronomer of Observatory Paris-PSL . For a lunar eclipse to take place, an almost perfect alignment is needed between the Sun, the Earth and the Moon . So, when our planet is between the star and the satellite, it casts its shadow on the moon that darkens it.
The Full Moon gradually enters the shadows then in the shade to be totally dark before gradually leaving this area. The complete phenomenon will begin at 17H14 GMT (12:14 in Peru) and will end at 23H28 (06:28 pm) . However, the show in heaven will not begin until 1824 GMT (13:24 Peru) when the Moon will begin to give the impression of being erased from the sky.
The most interesting of the eclipse, when the Moon is completely in the shadow cone projected by the Earth, it will start at 19:30 GMT (14:30) and will end at 21:13 GMT (16:13 ) . This phase, called the "totality" phase, will last close to one hour and three quarters (103 minutes) which will be the longest eclipse of the 21st century.
"Serious Problem"
This is the second total lunar eclipse of 2018 . The first took place on January 31st. Deprived of the rays of the sun, the Moon will darken and take on a brick tint : the atmosphere of the Earth deviates the red rays of light from the Sun towards the cone of shadow, They reflect like this on the surface of our natural satellite.
It is possible that the glow of the Moon is obscured because "it will pbad to the center of the shadow of the Earth where there is less refracted light, "warns Olivier Sanguy, of the City of Space Toulouse, in the south of France.The other protagonist of the night will be the planet Mars which will be 57.6 million kilometers from Earth.We will have to wait until 2035 to see the "red planet" so close to us.
At first glance, you may see a bright dot in the l & # 39; space but with a telescope, it will be possible to appreciate the details. The observation of the sky will also refute a rumor broadcast by social networks that Mars would seem as big as the Moon this Friday. "If that was true, we would have a serious problem given the gravitational force between Earth, Mars and the Moon ", joked NASA on his website. EFE and AFP )
