The Incarnation of the Moon? We are waiting for the longest of this century – Space – Science and Technology

After a three-year break, we will be able to see the complete eclipse of the moon on Friday, July 27th.

The complete phase lasts almost 104 minutes. It took three years
"Only" 73 minutes

An extraordinary eclipse length is given by the moon that runs through
near the middle of the shadow (so-called umbra) of the Earth. In good weather, it will be

the eclipse will go relatively close to the horizon. This is good
an opportunity for interesting photographers and hunters. Zatmenie
will end on Saturday, July 28 about 20 minutes after midnight. Another complete
the lunar eclipse will be the morning of Monday, January 21, 2019, and its full
the phase will last 102 minutes

The shadow of the Earth falls on the surface of the Moon

The eclipse of the Moon is an astronomical phenomenon in which the shadow of the earth falls
the surface of the Moon. It happens in time around fulfillment, when the moon is during its

geometric shadow but shadow influenced by the atmosphere of the Earth

If the Earth was without atmosphere, the shadow of the Earth would be restrained,
homogeneous and would not be seen in it. There are no eclipses
however, the darkening of the monthly disc is over; its center is reddish and circled
Grey. The properties of each shadow depend on these parts of the earth
the atmospheres through which the respective sun rays have passed. It's a change

moreover, the closer they are to the surface of the earth

A ring of light that runs through the atmosphere grows so much that
can light up the entire lunar disc slightly in the shadow of the earth. In the interior
a part of the shadow is another attenuation due to the diffusion of the light on the molecules
air (we thank him for the blue color of the day sky) and also disperse on
dust and cloud cover. This is how the violet and blue rays are the weakest
with regard to the red and the orange, who then in the sunlight
prevail. The course of the density (and therefore the refractive index) of the upper atmospheres has

From observations of eclipses in the past, the relationship between magnitude

The French artist and astronomer Lucien Rudaux, living between 1874 and 1940
1947. At that time, the astronaut would see the eclipse of the Sun with the edge of darkness
the disk of the Earth would be lined with a reddish ring of morning and evening harnesses, which
would surround the white pearl crown of the sun. The astronaut would be around the moon
the landscape with its reddish color resembled the surface of Mars

A less striking phenomenon is the flattening of the Earth's shadow. Really observed
the flattening of the earth's shadow is much larger than the Earth itself. It is possible
explain by flattening the atmosphere that is caused by the rotation of the Earth and the Earth
higher density (and therefore lower thickness) of the cold polar atmosphere.
From the precise astronomical observation of the moon moon,
flattening of the atmosphere is up to four times greater than the flattening of the earth

The circular shape of the Earth's shadow on the moon led to old Greeks
astronomers to conclude that the Earth is a ball. Attraction experience

other improvised position
