Explanation: In late 2021 there was a total solar eclipse visible only at the end of the Earth. To capture the unusual phenomenon, airplanes took flight below the clouded seascape of Southern Ocean. The featured image shows one relatively spectacular capture where the bright spot is the outer corona of the Sun and the eclipsing Moon is seen as the dark spot in the center. A wing and engine of the airplane are visible across the left and bottom of the image, while another airplane observing the eclipse is visible on the far left. The dark area of the sky surrounding the eclipsed Sun is called a shadow cone. It is dark because you are looking down a long corridor of air shadowed by the Moon. A careful inspection of the eclipsed Sun will reveal the planet Mercury just to the right. You won’t have to travel to the end of the Earth to see the next total solar eclipse. The total eclipse path will cross North America on 2024 April 8, just over one week from today.

说明: 2021年底发生了只有南极才得见的日全食。而为了捕捉这个特殊的景观，数架飞机特地飞在南极海域的云层下方。于拍下的许多影像里，上面这张主题影像呈现其中较精采的一幅。在这幅影像里，中心附近的亮区是太阳的外层日冕，其中心的暗区则是造成此次食象的月亮。此外，在影像的左下角，可见到拍摄者所搭乘飞机的机翼和引擎，而另一架前来观赏日食的飞机，则出现在左缘附近。全食日周围的暗区，称为影锥，而它之所以很黝黑，则是因为你我的视线恰好望入月亮所投射出的长长本影锥。如仔细检视全食日附近的区域，不难找到出现在它右侧的水星。不过，要看下次的日全食不用去世界的尽头。在一个多星期后的2024年4月8日，日全食的全食带将划过北美洲。
