Probably everyone in life has ever heard or even seen such a phenomenon as a solar eclipse. And did
you ask yourself the question, where does it come from, what are the reasons for its occurrence, in
general, what is this phenomenon of nature?
From ancient times, solar and lunar eclipses, like other rare astronomical phenomena, such as the
appearance of comets, were perceived as negative events. People were very afraid of eclipses, since
they occur rarely and are unusual and frightening phenomena of nature. In many cultures, eclipses were
seen as harbingers of misfortunes and catastrophes (especially in the case of lunar eclipses, apparently
because of the red color of the shaded Moon associated with the blood). In mythology, eclipses were
associated with the struggle of higher forces, one of which wants to break the established order in the
world ("extinguish" or "eat" the Sun, "kill" or "pour blood" on the Moon), and the other – to preserve it.
The beliefs of some peoples demanded complete silence and inaction during eclipses, others, on the
contrary, active witchcraft to help "the bright forces".
Saros (the cycle, whose length is 6585.3 days, or 18 years, 11 days and just under 8 hours) was known to
astronomers of ancient Egypt and Babylon. Thanks to Saros, ancient astronomers accurately predicted
eclipses, without having a clear idea of ??the celestial mechanics, nor computing devices. Indeed, in order
to predict the date and time of the eclipse, it is sufficient to have a list of the last occuring eclipses and
add to the date and time of each of them an integer number of Sarosses. The prediction of lunar eclipses
in general is not difficult. With solar eclipses everything is somewhat more complicated, since it is
necessary to take into account that when the eclipse is repeated through Saros its strip will pass in
another place, and be able to calculate this place. To facilitate the calculation of solar eclipses, ancient
scientists used the triple Saros – period equal to 19755,
The predictions of the Saros eclipses give acceptable accuracy within plus or minus 300 years, at more
remote times, failures begin, caused by the accumulation of errors.
We all know the only living planet is Earth which like any other planet revolves around the Sun. And like
any other planet, it also has its own satellite which is the Moon. The relationship between the Sun, Earth
and Moon yields into the two phenomenons of nature, Solar eclipse and Lunar eclipse. Before we
proceed any further, you should understand that what is eclipse? An eclipse is the shadowing of any
celestial body due to any other celestial body. It is a temporary obscuration which occurs due to
constant movement of astronomical bodies.
Let’s talk about Lunar Eclipse. Lunar eclipse occurs when the moon enters the cone of the shadow cast
by the earth. The diameter of the Earth's shadow spot at a distance of 363,000 km (the minimum
distance of the Moon from the Earth) is about 2.5 times the diameter of the Moon, so the Moon can be
shaded entirely. And for the solar eclipse, during new moon, the moon casts its shadow on sun by
coming in between the Sun and the Earth.
When the shadow of the Earth falls on the moon, and it disappears from the horizon. The Earth rotates
around the Sun, and the Moon revolves around the Earth. Both these processes occur simultaneously. If
for a few minutes the Moon, the Earth and the Sun are on the same line, the eclipse begins. A total solar
eclipse is a very rare and dramatic event. During a total solar eclipse, one gets the impression that some
huge monster loses the Sun after the piece. When the Sun disappears, the sky becomes dark and the
stars are visible in the sky.
