   Explanation: Yesterday there was a total solar eclipse visible only at
   the end of the Earth. To capture the [7]unusual phenomenon, airplanes
   took flight below the clouded seascape of [8]Southern Ocean. The
   [9]featured image shows one relatively spectacular capture where the
   bright spot is the outer [10]corona of the Sun and the [11]eclipsing
   Moon is seen as the dark spot in the center. A wing and engine of the
   [12]airplane are visible across the left and bottom of the image, while
   [13]another airplane observing the eclipse is visible on the far left.
   The dark area of the sky surrounding the [14]eclipsed Sun is called a
   [15]shadow cone. It is dark because you are looking down a [16]long
   corridor of air shadowed by the Moon. A [17]careful inspection of the
   eclipsed Sun will reveal the [18]planet Mercury just to the right. The
   [19]next total solar eclipse [20]shadow will cross parts of
   [21]Australia and [22]Indonesia in April of 2023, while [23]the one
   after that will cross [24]North America in [25]April of 2024.
