Explanation:
Changes in the
alluring solar corona
are detailed in this
creative composite image
mapping the dynamic outer atmosphere of the Sun during two separate total solar eclipses.
Unwrapped from the complete circle of the eclipsed Sun's edge
to a rectangle and mirrored, the entire solar corona is shown
during the
2017 eclipse (bottom)
seen from Jackson Hole, Wyoming, and the
2023 eclipse from Exmouth, Western Australia.
While the 2017 eclipse was near a minimum in the
Sun's 11 year activity cycle,
the 2023 eclipse was closer to solar maximum.
The 2023 solar corona hints at the dramatically different character
of the active Sun,
with many streamers and pinkish prominences arising along the solar limb.
Of course, the solar corona is only easily visible to the eye
while standing in the shadow of the Moon.
