Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

    [2]The Sun is shown during a total solar eclipse. Accentuated is the
      expansive corona of the Sun, which is shown streaming out in all
    directions. Please see the explanation for more detailed information.

   Explanation: Only in the fleeting darkness of a total solar eclipse is
   the light of the solar corona easily visible. Normally overwhelmed by
   the bright solar disk, the [4]expansive corona, the [5]sun's outer
   atmosphere, is an alluring sight. But the subtle details and [6]extreme
   ranges in the corona's brightness, although discernible to the eye, are
   notoriously difficult to photograph. [7]Pictured here, however, using
   multiple images and digital processing, is a detailed image of the
   Sun's corona taken during the [8]April 20, 2023 total solar eclipse
   from [9]Exmouth, Australia. Clearly visible are [10]intricate layers
   and glowing caustics of an ever changing mixture of hot gas and
   [11]magnetic fields. Bright [12]looping prominences appear pink just
   around the Sun's [13]limb. A similar solar corona might be [14]visible
   through clear skies in a [15]narrow swath across the North America
   during the total solar eclipse that occurs [16]just six days from today
