Explanation: Yesterday 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. The next total solar eclipse shadow will cross parts of Australia and Indonesia in April of 2023, while the one after that will cross North America in April of 2024.

说明: 昨天发生了只有在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。在拍下的诸多影像里，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。全食日周围的暗区，称为影锥；它之所以很黝黑，是因为你我的视线恰好望入月亮所投射出的长长暗影锥。如你仔细检视全食日附近的区域，不难发现出现在它右侧的水星。下次的日全食将发生于2023年的4月，全食区包括澳洲和印尼的部分区域。而下下次的日全食则在2024年4月，全食带会通过北美洲。
