Solar eclipse phenomenon

The solar eclipse is an astronomical phenomenon that occurs if the Earth, the moon, and the sun are located roughly one line, where the moon is in the middle of them, and here the sun is either partially or completely obscured. At the time when the moon is born, that is, at the beginning and end of the lunar months. Some may wonder how this small moon could cover the giant sun at the time of the total eclipse. The secret lies in the miraculous arithmetic relationship between the difference between the size of the sun and the size of the moon and their distance from the earth. Since the disk of the sun is 400 times larger than the disk of the moon. At a time when the sun is 400 times farther than the moon.

Every time the moon revolves around the earth, it passes between the sun and between it, preventing the sun's rays from reaching the earth, but most of the time the sun and the moon do not meet at the same level.

Types of solar eclipses

Annular solar eclipse

In an annular solar eclipse, the moon is at a point far from the earth, because the path of the moon around the earth is oval, so the disk of the moon is too small to obscure the entire disk of the sun, so the disk of the sun is diffracted from the middle in the areas that lie in the extension of the shadow mixture.

Partial solar eclipse

In the case of a partial solar eclipse, it occurs in areas where the semi-shadow of the moon falls on the surface of the earth, and in this case, part of the sun's disk is deflected. There is another very rare type of solar eclipse, called the (hybrid eclipse). This type of eclipse occurs if a complete one is seen at one point, and annular at another point, then it is considered a hybrid eclipse.

A solar eclipse lasts about 6 minutes 54 seconds. But what would happen if we looked at sunlight directly during an eclipse phenomenon?. Looking at the sun when this phenomenon occurs is harmful to the eye and may damage the eyes within minutes, as the sun emits very harmful rays such as ultraviolet and infrared rays. Therefore, it is necessary to wear specially designed glasses.

 

In August of 1999 AD, the eclipse rose over Europe to cross the Black Sea, and the shadow passed its lowest speed across the earth at the speed of the Com Corrid plane, which reached a speed of 2000 kilometers per hour, but it can double the speed three times.

In 1998, he was seen across the southern Caribbean when the Earth, the Moon, and the Sun came together. Some of the enthusiasts came from around the world to an island called (the island of Curaçao) to witness a complete solar eclipse. They have strengthened cameras, binoculars, and other devices with special filters, which are the only ways currently to observe the sun safely.

In 2019, the Earth witnessed a solar eclipse that lasted 3 minutes and 40 seconds in a phenomenon known as the (Ring of Fire). This was the third and last eclipse of this year. It is expected that the residents of Saudi Arabia, Qatar, the Emirates, and Oman will be able to see the eclipse, in addition to areas in southern India and Indonesia. And Singapore and Malaysia, and the best place to see this phenomenon, according to what experts announced would be from eastern Saudi Arabia. Many people on social media paid great attention to the topic of the eclipse, so the hashtag activated # in the name of the phenomenon, as it was among what people in Saudi Arabia searched most on Google.

Several things were discovered from the occurrence of a solar eclipse, including, helium gas. It happened on August 18, 1868, when astronomer (Jules Jensen) studied the light spectrum of the sun during a total eclipse and noticed the presence of a light yellow spectrum, and he initially thought It is the element sodium, but the astronomer (Norman Lockyer) noticed the presence of yellow in the light spectrum of the sun two months after the total eclipse in that year, and astronomer Norman Lockyer and chemist Edward Frank Land called it (Helios) after the name of the sun in the Greek language.

The solar eclipse was one of three tests to prove the theory of relativity of Albert Einstein after Einstein published his theory of relativity in 1915 and proposed three tests, if one of them fails, his famous theory of relativity will collapse, one of these tests was based on monitoring the deflection of light by the gravitational attraction of masses and after accurate calculations made by Einstein predicted With a total solar eclipse in 1919, this was an opportunity to study the stars behind the sun and compare them, and indeed, the proven locations of these stars to prove the validity of his theory of relativity.

Did you know that a total eclipse will cause the electrons of the atoms of the ionosphere to be removed from the atmosphere when a total eclipse occurs, the atoms of the upper layer of the atmosphere and the features of the ionosphere or the ionosphere extract their electrons, causing the expansion and contraction of the ionosphere, and NASA has funded eleven earth stations to observe the eclipse and three One of them is to observe the ionosphere, to hoard the opportunity of a total eclipse, and to study the relationship of the ionosphere, but the sun, and the extent of its influence on the radio signals and their reflection back to Earth through the expansion and contraction of the ionosphere.

A total eclipse only occurs in the same city every 375 years, according to astronomers ’calculations. The phenomenon of total eclipses does not pass in the same city or region, which makes it a unique phenomenon. If one of us witnesses it, it will be the only time in our life, and this thing does not apply to total eclipse chasers around the world.
