It was May 28, 585 BC. C. The place was a battlefield in Asia Minor. Banks and fears were in conflict. Suddenly the sun darkens. Amazed by the spectacle, the fighters immediately ended their Six Year War.
What caused the seemingly strange darkness? It was due to a solar eclipse.
Our 1976 solar eclipse
Although many people were afraid centuries ago when a solar eclipse darkened the sun, millions of people expected a total solar eclipse on October 23, 1976. Helhetsvägen, a strip of about 160 kilometers from large. , started near Lake Victoria in Central Africa, crossed the Indian Ocean and found land in the far south-eastern part of Australia. It passed through the state of Victoria, including the capital Melbourne, where the population witnessed a total solar eclipse for the first time in more than 140 years. After crossing the south coast of New South Wales, the show went deep into the Pacific.
Many professional and amateur astronomers were among those who witnessed this celestial event on Saturday October 23, 1976 around 4:30 p.m. The entire phase of the show lasted about three minutes. It is estimated that two million people in Victoria watched the solar eclipse on television.
On the way to the solar eclipse, Jehovah's Witnesses used three locations for Christian communities. Because the solar eclipse occurred during the afternoon rallies, only a few rallies saw it in person. Like most people in Australia, later that day she saw it on TV with interest.
You may have seen a total solar eclipse. If so, do you know what is causing this show? You might feel like there is a danger that you will examine it right away. It is true? Do these eclipses also have advantages?
A great show
Simply put, a solar eclipse occurs when the moon moves to a position directly between the sun and the earth. If the sun is not completely hidden from the moon, the solar eclipse will be partial. A total solar eclipse occurs when the sun is completely hidden from the moon. A partial solar eclipse can occur up to five times a year in different places on earth. But a total solar eclipse rarely occurs anywhere on earth.
The moon casts two shadows during the total solar eclipse. One, called umber, is the full shadow and is shaped like a sharp cone. The point or apex is on the surface of the earth and the base of the cone is the circumference of the moon. The smaller or half of the shadow, called penumbra, goes in the opposite direction. Its little end faces the moon. The penumbra spreads out much more on each side than the umbrella. In this area, observers see a partial solar eclipse, as the moon only overlaps the sun to varying degrees.
What makes a total solar eclipse so fascinating? Well, very little happens for the first hour and a half as the moon's shadow slowly moves across the face of the sun, which gradually takes on the shape of a crescent moon. However, when the crescent moon becomes very thin, dawn begins to start. Suddenly the sun disappears! The celestial sky "disappears", the temperature drops, darkness drops, stars appear, and the total solar eclipse begins. Once again, the moon has turned off the sun!
After that, the corona, the sun's outer gas layer, can be seen as a beautiful white halo that is about twice the size of the sun and surrounds the dark disk of the moon. Truly an unforgettable spectacle! For a few seconds, at the start and end of the overall phase, there appears to be a series of small beads around the sun. This phenomenon is caused by the light shining in the valleys of the moon. The bright spots are called Baily Beads and are named after the English astronomer Francis Baily, who recorded his appearance during a solar eclipse in 1836. When the daytime sky is clear, the general appearance of the landscape diminishes with the full moon. It is not quite dark.
At about the same time, when the moon covers the bright side of the sun or the photosphere, it only flashes for a few seconds and like an arc around the black moon, pink chromosphere, or the color of the sun. This is known as the "ray spectrum" and is based on a rare envelope of light gas that sits directly on the bright surface of the sun. This is known as the "ray spectrum" and is caused by a dilute envelope of glowing gas immediately above the bright surface of the sun. At the end of the entire operation, a second flash occurs. Just before and after the totality, when a thin crescent of the sun is seen, bands of light and shadow appear on the floors and walls of the buildings. They swing like waves and move perpendicular to their length.
Suddenly the sun reappears in the form of a thin crescent! Daylight returns at dawn. The sun's crescent moon gradually grows until one and a half hours later the moon leaves the solar disk. Daylight returns.
Multiple answers
The solar eclipse is so impressive that some primitive people think it is a weakness or even a disease and the death of the sun. Some Eskimos and Aleutians believed that during this event the sun and moon moved out of their normal positions to better see things on earth. In Tahiti, solar eclipses have been explained as a mating of the sun and moon that are believed to form stars.
In the realm of reality, this temporary eclipse of the sun disturbs birds and animals. During the twilight of the solar eclipse, the bees stop buzzing, the birds stop chirping, the chickens become still and the cattle perch in the fields as if it were sunset. "Go to bed" a "night" of about three minutes.
Safe display of a solar eclipse
A few weeks before the solar eclipse on October 23, 1976 in southeastern Australia, the media repeatedly warned people not to watch the show directly. All Path of Eclipse residents were encouraged to stay home and watch television, rather than risk permanent eye damage when watching or photographing Eclipse themselves. Special committees have been set up to inform all concerned about the dangers of witnessing this heavenly event.
The risk of eye damage decreases with time (the minutes the sun is completely dark). But for half an hour before or after an irreparable eye injury, it would happen if a person observed the solar eclipse directly or photographed it without a special protective lens.
Knowledge acquired through solar eclipses
Many interesting facts have been learned from solar eclipses. Think, for example, of the sun's crown or crown. During a total solar eclipse, it looks like an icy haze of light rays from the now dark solar disk. A very beautiful sight against the backdrop of an intense blue sky! By measuring the polarization of particles in the inner and outer regions of the corona, scientists can determine where the solar atmosphere ends and where the particles begin, which are refracted by light from space.
Pink shocks or giant flames from light bulbs that stretched thousands of miles from the sun provided additional information. These flaming lumps impress with the beneficial role of the sun, like a blazing fire that emits its radiant heat in the cold room around it. During the study of these torches, helium, a previously unknown chemical element, was first discovered in 1868.
The exact orientation of the sun, moon and earth at the total solar eclipse also allows accurate measurements of the earth's surface in the general area covered by a solar eclipse. A review of the approved measures is then carried out. However, the use of this information is jeopardized due to the rarity and diversity of sites for total solar eclipses.
The longest total solar eclipse in modern times occurred on June 20, 1955 in the Philippines. It lasted 7 minutes and 7.7 seconds.
