2021年底，只有在地球的尽头才能看到日全食。为了捕捉这一不寻常的现象，飞机在南大洋云层密布的海面下飞行。这张特色图片显示了一张相对壮观的照片，其中亮点是太阳的外日冕，而月食的月球被视为中心的黑点。在图片的左边和底部可以看到飞机的机翼和发动机，而另一架正在观测日食的飞机则在最左边。天空中围绕在日食太阳周围的黑暗区域被称为影锥。天是黑的，因为你俯视着一条被月亮遮蔽的长长的空气走廊。仔细观察日食后的太阳，你会发现水星就在它的右边。你不必跑到地球的尽头去看下一次日全食。全食路径将于2024年4月8日穿越北美，距离今天只有一周多的时间。NASA报道：2024年4月8日的日全食

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. NASA Coverage: Total Solar Eclipse of 2024 April 8
