The video shows a series of images depicting a solar eclipse. The eclipse begins with the sun partially obscured by the moon, casting a bright light on the moon's surface. As the video progresses, the moon moves across the sun, gradually covering it completely, resulting in a total eclipse. The sun's corona, the outer atmosphere, is visible around the moon's silhouette, creating a halo effect. The video ends with the sun fully obscured by the moon, leaving only a thin crescent of light visible.
