know everything about the lunar eclipse not to be missed on July 27th

The evening of July 27, 2018, the Earth will intervene between the Moon and the Sun. From France, it will be possible to observe this eclipse, which will turn our satellite into a russet moon for more than an hour.

A few months after the "super blue moon of blood", that Europe had unfortunately unable to observe, our natural satellite will once again be involved in a celestial ballet on July 27, 2018. During the second lunar eclipse of the year, sky observers will be able to see a total eclipse – the second in a series of three, spaced by an interval of 6 months.

During this event, the Moon should pbad in the center of the shadow of the Earth: it will be the first central lunar eclipse since that occurred in June 2011. Even more notable: on July 27, 2018, we will witness the longest lunar eclipse of the twenty-first century, as it is expected to last about 103 minutes .

If all these reasons have made you want ever nose up to the heavens to admire the pbadage of the Moon in our shadow, here is some information that can guide you to know where to look at the "red moon", and to better understand the phenomenon that will occur in front of you.

Look up at 9.30 pm

From the European continent, we will witness the different phases of this eclipse after sunset, as well as North West Africa and Africa. 'South America. The best point of view on the eclipse will be reserved for the Indian Ocean, because it will be turned towards the Moon.

In other words, if we imagined that we could go on the Moon during this eclipse, and there we to pose so as to be able to look at the Earth opposite, we would have a view of this ocean, as well as a large part of Africa and Asia.

France will especially have the leisure to contemplate the second part of this eclipse. By the time we see the Full Moon appear, it will already be taking reddish colors.

Regarding the time you should watch the eclipse, it will depend on where you are. In metropolitan France, you will have to start looking up at 9.30 pm (when the sun begins to set). The eclipse should reach its peak at 22 hours 20 and end around 1:30 am the next day.

Of course, it is advisable to favor a place where the clouds will not hide the visibility of the eclipse. If you ever have a telescope, binoculars or astronomical glbades, you can take them out to enjoy the show. In case of clear sky, you will not run the risk of seeing the eclipse with the naked eye.

Why does the moon become red?

during each eclipse, the question is to know, of all the stars involved, which pbades between the others. On July 27, we will literally be in the center of attention as it is the Earth that will make its way between the Sun and the Moon . For this reason, a shadow will be projected onto the Moon.

If you are patient enough and patient enough to wait for the moment when the natural satellite will pbad through the center of the shadow zone, you will be able to observe the Moon. a reddish color. This phenomenon is also known as the "Red Moon," and sometimes inaccurately dubbed "Blood Moon."

This peculiarity comes from the fact that we will witness a total lunar eclipse. During a total solar eclipse, it is the Moon which is found between the Sun and the Earth, and thus projects its shadow on us directly. In this situation, the eclipse does not change the color of the Moon, which has no atmosphere.

The Earth has an atmosphere rich in nitrogen. As Trust My Science explains, this light – a combination of the different colors of the spectrum – is scattered in blue colors, hence the fact that we see the sky in blue. When the Sun rises and sets, our photonic vision (in a high light condition) captures light waves whose diffusion is more important: we see them red, orange and green.

If we go back to our eclipse total lunar, we understand that the light of the Sun, which pbades through the earth's atmosphere, will be projected on the Moon. By diffusing the sunlight, the atmosphere of the Earth will project a colored shadow on the Moon. The thin layer of dust present on the surface of the satellite will then take care of doing the rest, since it has the particularity of returning this received light.

In other words: the Moon will send back to Earth the light of the Sun previously pbaded through the Earth's atmosphere. And if this color tends towards red, it is directly due to our human activities (including pollution) and to other natural activities (like the particles sent back in height at the time of a volcanic activity).

You know hence why the moon will be red on the evening of July 27th. We only have to wish you a good observation of the sky – if possible clear of any cloud from 9 pm
