In all and po for all, from the beginning to the end, that is to say from the moment when our natural satellite will enter the penumbra until the moment when it will leave, nearly 6 h 14 min will have elapsed . Naturally, the eclipse will not be visible anywhere in the world. It will be invisible in 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.

Where to observe the eclipse of the Moon in France?

En Metropolitan France, we will have the right to the second part of the eclipse. When the Full Moon comes up, we will find 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.

The Martians will not come to attack us.

At the same time, remember that a lunar eclipse demonstrates that the Earth is round. The shadow of our planet projected on our satellite is well and truly round. That proves easily that the Earth is not flat as the "platists" are convinced of it.

What to remember

• The 27th of July will be the longest total eclipse of the Moon of 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 eclipse of the Moon the night of March 3 to 4, 2007

Article Jean Etienne published on March 2, 2007

If the clouds do not play intruders, we will live during the night of 3 to March 4, an astronomical event popular with fans: a total eclipse 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 TU, 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, because the orbits are not exactly in the same plane. In practice, these conditions are met in March and November, when the Moon pbades through what is called the "node" of the orbit.

There are three types of eclipses of the Moon:

• Eclipses by the penumbra, when the Moon pbades only in the penumbra cone of the Earth. These eclipses are not very spectacular and are barely visible.

• Partial eclipses, when the Moon pbades partially in the earth's cone of the earth.

• The total eclipses, when the Moon pbades entirely in the Shadow cone of the Earth

On March 3, 2007, we will experience an eclipse of the third category cited, 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.
