July last Friday is the longest eclipse of the moon this century

Historical sources indicate that in the 4th century BC Aristotle, an eminent Greek thinker, experienced a great deal of interest in celestial mechanics. After observing the eclipses of the moon, the famous scientist finally realized that the Earth is round – after all, a circular and non-oblong shadow of our planet falls on a circle of light fullness!

Today, we know the structure of the universe better than the ancient astronomers. The essence of Aristotle was, in principle, right: this phenomenon occurs when the Sun, our planet and the Moon form a line. And during any complete eclipse, we can not see the eclipse due to the fact that the plane of the moon's orbit does not match the Earth – it leans slightly on its way to the sky, the moon usually falls on or under the shade.

It is true that three variants of eclipses stand out: a situation in which the moon forms a cosmic body in the form of a half-shadow of the Earth, called a hemispherical eclipse; if the shadow is obstructed only by the Moon, we observe a partial eclipse; the shadow of our planet "melts" completely the moon, there is a complete eclipse

Partial eclipse of the moon. between them, of course, is the latter, since our cosmic neighbor continually crosses all the phases – hemispherical, partial and finally complete, and the moon is hunting in the shadow, the phase repeats itself in the reverse order.

When will be the lunar eclipse

The phase Eclipse of the celestial moon of the world will begin at 17 hours. 15 minutes (20 hours 15 minutes in Lithuania), and the partial eclipse will go to 18 hours. 24 minutes (21h 24h Lithuanian time)

We will not see the beginning of the phenomenon, because in Vilnius the moon will be around 21 hours. 20 minutes, but we will already be able to observe a partial eclipse – a full dark-skinned disc should be examined on the southeast side of the horizon.

The beginning of the complete eclipse is 22 hours. 30 minutes, maximum – 23 hours 22 minutes, and the end is 0 hours. 13 minutes

At this time we will see the moon in the southern part of the parenthesis at the highest point of her celestial journey. The partial eclipse will end in 1 hour. 15 minutes, and a pennant the neighbor of our planet will finally freeze for 2 hours. 29 min, ie 23 hours 29 minutes "The eclipse of the moon is not a very rare phenomenon, it is special because it will be the longest of the century – our satellite will travel almost to the center of the Earth's shadow, "says the astronomer, the Lithuanian Ethnocosmological Museum. speaker Dr. Vidas Dobrovolskas. – It is difficult to predict the brightness and color of the moon during a complete eclipse, but it is possible that the disk is flooded with redness and that the shadow of the Earth is the thickest. from the transparency of the earth's atmosphere – the cleaner it is, the less solid it contains, the more sunlight penetrates through it and illuminates the moon when it is in the shadow of the Earth. Therefore, during the eclipse, the color of fullness varies from bright red, if the atmosphere is clear, to dark gray if it is contaminated.

There have been no intense volcanic eruptions on our planet recently, studies show that the amount of dust and aerosols in the 39; atmosphere is weak and therefore very clean, "says a scientist

We recall that unlike the solar eclipse, there is no need for eye protection to observe the eclipse of the moon – you can look at the naked eye, and the binocular or telescope, of course, enhances the impression.Although the light of the city to admire the phenomenon is in principle not an obstacle, it is nevertheless recommended to choose the darkest and open area of ​​the highway.

We wish you a clear sky! And if the weather conditions are not favorable to the observation, you can see the live broadcast of the eclipse on the Internet here
