The Great American Eclipse

The Great American Eclipse was a total solar eclipse visible across the United States on August 21, 2017. During this event, the Moon moved precisely between the Sun and Earth, blocking the Sun’s light in a narrow path called the path of totality. Observers within this path experienced complete darkness for a few minutes, revealing the Sun's corona—the glowing outer atmosphere. Outside the path, viewers saw a partial eclipse. This rare alignment offered a unique opportunity to witness a dramatic change in daylight and provided important scientific insights into the Sun’s structure.
