do not miss the longest of the century on July 27!

Two weeks after the partial eclipse of The Sun is the closest star to the Earth, from which it is distant about 150 million kilometers. The Sun is located at 8.5 kparsecs from the center of the Milky Way. In the classification of stars, the sun is a star of type G2.

This 27th of July will therefore be the second total lunar eclipse of the year, which will also be the longest of this XXI ^e century (the longest in the XX ^e century lasted 105.7 and 106.4 min, respectively in July 1982 and 2000).

In all and for all, from the beginning to the end, that is to say to say the moment when our natural satellite will enter the penumbra (19459009) until the moment when it will leave, nearly 6 h 14 min will have elapsed .. Naturally, the eclipse will not be visible everywhere in the world It will be invisible in America North and Central America and in much of the Pacific. However, if you are in the other half of the world, the event can be observed either in part or in its entirety. And the best place to enjoy it will be … Reunion Island. So, if you have the chance to live there or go there on this date, you can follow the event from start to finish, all through the night. At the height of the eclipse, in the middle of the night, the Moon will be near the zenith, at the highest point in the sky. But no "moonshot" to be feared, the pale star will be more discreet than usual, extinguished by the shadow of the Earth.

Visibility of the lunar eclipse in France

In France metropolitan, we will be especially entitled to the second part of the eclipse. When the Full Moon rises, we will discover it blushing. The totality begins at 19:30 UT. So of course, depending on where you are, our satellite will not come out at the same time from the east, southeast. For example, in the offices of Futura, in Saint-Raphael in the Var, the sun will sink under the horizon at 9 pm, Paris time. Almost at the same time, on the opposite side, the Moon will rise above the horizon. But of course, depending on whether the horizon around you is flat or planted with hills, mountains, rows of trees or buildings, the Moon will emerge a little later … (note in passing that There are apps for smartphones with augmented reality that help you choose the best place to observe and / or photograph the sunrises, sunsets of Here is a list of celestial objects that can be called stars (no … "data-image =" https://www.cdn.v5.futura-sciences.com/buildsv6/images/midioriginal/6/c/c/6cc6562b02_127395_astre-c-esa-hubble-nasa.jpg "data-url =" / sciences / definitions / etoile-astre-851 / "data-more =" Read more "> stars etc .: Sun Seeker, Photographer's Ephemeris, Photopills …).

If you live in the Montpellier area or in the Cévennes park for example, the Sun will bow a little later and the Moon will not leave the tip of its nose (red) before 9:15 pm. In Bordeaux, the Moon will only show itself at p In Brittany, it will be necessary to wait 9:45 pm. For the observers located in the west of France, Normandy and also the Hauts-de-France, the totality will have already begun at the rising of the Moon. But the show will continue until 23:28 UTC, when the Moon leaves the dim light of the Earth. See the hours of visibility for your city here

A very dark lunar eclipse

Although our satellite sinks into the shadows of the Earth, it will not become as invisible but darker. The palette of colors projected on the star, usually pale, will vary according to the layers of the atmosphere crossed by the rays of the Sun. The light that will pierce the lower layers will be more refracted. And according to the population of The formation of the clouds
The quantity … "data-image =" https://fr.cdn.v5.futura-sciences.com/buildsv6/images/midioriginal/b/7/e /b7e2382b95_59611_mer-nuages-seblino-camptocamporg-cc-30.jpg "data-url =" / planet / definitions / climatology-cloud-14525 / "data-more =" Read more "> clouds on the limb at that time and also the abundance of dust, etc., the colors will be varied.For this eclipse of July 27, 2018, the Moon will be singularly darker because it will be located almost at the point of its farthest orbit Earth's highest peak (more than 404,300 km) and will be close to the center of the shadow, the apparent size of the Full Moon will be almost at its lowest (0.49 °). [19659003] In metropolitan France, therefore dazzling Full Moon point during this first half of night.The conditions will be conducive to divert the eyes from time to time of the Moon in order to observe the silver-light arc of the Milky Way (it crosses the sky from north to south), and to try to catch shooting stars. Because yes, at this date, we can already see several. Perseid rain will have started for 10 days. The strongest activity of the meteoritic swarm will be, meanwhile, the night of August 12 to 13.

Finally, remember that many planets are also visible to the naked eye in July and even an asteroid (as well as a nova and perhaps a comet soon). Among them, Mars, red point become in recent days more brilliant than Jupiter. On July 27, the day of its opposition, the Moon will pass only 6 ° next.

What to remember

• July 27 will be the longest total eclipse of the Moon of the XXI e century.
• The totality will last almost 103 minutes.
• The eclipse will be visible in metropolitan France but the best place to see it in its totality is Reunion.

The total lunar eclipse the night of March 3 to 4, 2007

Article Jean Etienne published March 2, 2007

If the clouds do not play intruders, we will live during the night of March 3 to 4 next an astronomical event popular with amateurs: a total eclipse of Moon. The first visible in France since October 28, 2004. Feel free to send us your photos to [email protected] we will publish!

The show will begin at 20h 16mn 29sec UT, as the Moon enters the darkness. But at this moment the darkening of our satellite will still be very timid, and it is from 21h 30mn 04sec TU that the Moon will plunge into the cone of shadow that the Earth carries with it, to the opposite of the Sun

note: every hour of this article is expressed in UT (Universal Time), add one hour to get the French time.

At this precise moment, the shadow of the Earth will begin to nibble the edge of the Full Moon. Quickly, you will see it gain ground by gradually revealing its roundness that of your own planet which is emerging in Chinese shadow more than 400,000 kilometers away. It is during similar moments that one understands how much Astronomy could impress the Ancients …

From 22h 43mn 49sec the shadow will completely swallow the lunar disk. But the show will only be reinforced, because the moon will then be painted an orange-red dress that intrigued many astronomers of past times. This hue is simply caused by the Earth's atmosphere, which plays the role of a Season of the lens

But this one will be invisible in Europe.

Eclipse of Moon

The eclipse of Moon occurs obliga at the precise moment of the Full Moon, since the three stars (Sun-Earth-Moon) are aligned. Note, however, that each Full Moon is not accompanied by an eclipse, since the orbit in astronomy
In astronomy, the orbit designates the closed trajectory followed by a celestial body around another celestial body so periodic, under the influence of the … "data-image =" https://fr.cdn.v5.futura-sciences.com/buildsv6/images/midioriginal/9/2/e/92eefd02ac_49145_iss-terre-soleil -nasa-s-marshall-space-flickr-flight-center-cc-nc-20.jpg "data-more =" / sciences / definitions / universe-orbit-873 / "data-more =" Read more "> orbits are not exactly in the same plane.In practice, these conditions are met in March and November, when the Moon goes through what is called the "node" of the orbit. 19659004] There are three types of lunar eclipses:

• The eclipses by the penumbra, when the Moon passes only in the penumbra cone of the Earth.These eclipses are very little spectacular and are hardly visible s

• Partial eclipses when the Moon partially passes into the earth's cone of the earth

• Total eclipses, when the Moon passes entirely into the shadow cone of the Earth the Earth.

On March 3, 2007, we will experience an eclipse of the third category mentioned, the most spectacular. However, the off-center position within the earth's cone of shadow will likely cause a fairly large difference in brightness from the north to the south of the lunar screen, the progression of which will be interesting to observe.

observe the phenomenon, a good pair of eyes are enough … and any shield is useless, the Sun being by definition lying for the terrestrial hemisphere corresponding to the area of ​​visibility. Fans will bring a pair of binoculars or a low magnification telescope (30 or 40 x), and prefer to observe from a clear place, far from any pollution, both atmospheric and luminous.
