Not only is the “ great American eclipse ” the astronomical spectacle of the year, it can also serve as a scientific measuring instrument. Current solar telescopes create artificial eclipses by placing black circles in front of the solar disk, which allows people to study the outermost layer of the sun, such as the chromosphere. “Dozens of years ago,” explains Casas, “the only way to make these kinds of observations was during eclipses, when the Moon covered most the star’s light.” These phenomena are quite common and it allows for an accurate measurement of the Sun’s diameter. “As we know the diameter of the Moon very well and it has no atmosphere, we can use a total eclipse to calculate the exact diameter of the Sun,” adds Casas. The sun is a very stable star, so its dimensions barely change. The next total eclipse in Spain will be on August 12, 2026.
