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
expansive corona, the
sun's outer atmosphere,
is an alluring sight.
But the subtle details and
extreme ranges in the corona's brightness, although discernible
to the eye, are notoriously difficult to photograph.
Pictured here,
however, using over 120 images and meticulous digital processing,
is a detailed wide-angle image of the Sun's corona taken during the
Great American Eclipse in 2017 August.
Clearly visible are
intricate layers and glowing caustics of an ever
changing mixture of hot gas and
magnetic fields.
Hundreds of stars as faint as 11th
magnitude are visible behind the Moon and Sun, with
Mars appearing in red on the far right.
The
next total eclipse of the Sun will occur on July 2 and
be visible during sunset from a thin swath across
Chile and
Argentina.
