The longest lunar eclipse of the 21st century has begun to dye our red satellite this Friday, while Mars, almost at its closest point to the Earth, will shine in all its splendor.
The double show will be observed with the naked eye, without the need for protection as happens with eclipses of the Sun, except for clouds.
"All they have to do is … leave," encouraged the fans at the Royal Astronomical Society of London
The eclipse, which corresponds to the moment when the moon submerges 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 in Eastern and Southern Africa, the Middle East and India that the show will be best appreciated.
Visible on the east coast of Latin America
In Latin America the eclipse will be visible in twilight dusk Friday on the east coast of the continent, at Brazil, Uruguay and Argentina, although the austral winter may complicate the observation of the phenomenon.
In this link you can see the real time development of the eclipse, the exact locations and calendar to see the eclipse between Friday and Saturday.
"Unusual and interesting"
"We have an unusual and interesting conjunction of phenomena, the Moon should be dyed red, a little coppery, and Mars, known as" the red planet ", he will be at his side, very bright, with a slightly orange hue ", explains Pascal Descamps, astronomer at the Paris-PSL Observatory
For a lunar eclipse to take place, an alignment is necessary. So perfect 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 will gradually go into darkness and then into the shadows to be completely in the dark before leaving
The complete phenomenon began at 17:14 GMT (12:14 in Ecuador) and will end at 23:28 GMT (1965 in Ecuador)
The most interesting moment of the eclipse, when the Luna is completely in the shadow cone projected by the Earth, will begin at 19:30 GMT (14:30 in Ecuador) and will end at 21:13 GMT (16:13 in Ecuador).
This phase, called the "whole phase", will last for about 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 sun's rays, Luna will not only darken, but will take on a brick tint: the atmosphere of the Earth deviates the red rays of light from the Sun into the shadow cone, which reflect on the surface of our natural satellite.
It is possible that the brightness of the Moon is attenuated because "it will pbad through the center of the Earth's shadow, where the light is less refracted", warns Olivier Sanguy of the City of L '. Toulouse area in the south of France. 19659002] 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 can see a bright spot in the space but with a telescope it will be possible to appreciate the details.
The observation of the sky "If it were true, we would have a serious problem considering the gravitational force between the Earth, Mars and the Moon," he joked about the fact that Mars would be as big as Moon on Friday. NASA on his website. (I)
