On Thursday, the lenses of space agencies in a number of countries around the world captured the moments of an annular solar eclipse in a phenomenon known as the “Ring of Fire” eclipse. The eclipse appeared in a number of countries on the Asian continent, including the Kingdom of Saudi Arabia, Qatar, the Emirates, India, Singapore, the Philippines, Sri Lanka, and some parts of Australia and Africa. An annular eclipse is distinguished from a total eclipse by the moon's distance from the sun, which allows the sun's luminous corona to appear like a "ring of fire," hence its name. Although lovers of natural phenomena may enjoy seeing the “ring of fire,” it may be harmful to the naked eye. The American space agency NASA has warned against looking directly at the sun during the eclipse. NASA stated that “it is the most beautiful annular solar eclipse, but it is also the most dangerous” to the eye, and called for the use of lenses and sunglasses designed to view the eclipse, which protect the eye from rays that may harm the retina without the person feeling pain. The scientific explanation for the appearance of the “Ring of Fire” is related to the distance separating the Moon from the Earth. When the Moon is farther from the Earth during certain periods of the year, it appears three percent smaller than the size of the Sun. During the meeting of the sun, the Earth, and the moon in the middle of them in one line in orbit, the sun disappears behind the moon, becoming a black dot, and only its glowing halo appears. An annular solar eclipse occurred in 2017 and was visible throughout the United States, but this year's eclipse covers only small areas across the continents that it will pass through. Astronomers had previously expected the occurrence of this eclipse, which is considered the first of its kind this year and the last. The year 2019 witnessed the occurrence of a partial eclipse in January in northeastern Asia and the North Pacific Ocean, and a total eclipse in July in the South Pacific Ocean, Chile and Argentina.
