Explanation:
On some nights, the sky is the best show in town.
On this night,
the sky was not only the best show in town,
but a composite image of the sky
won an international competition for landscape astrophotography.
The featured winning image was taken in 2011 over
JÆkulsÀrlÑn, the largest
glacial lake in
Iceland.
The photographer combined six exposures to capture not only two green
auroral rings, but their reflections off the serene lake.
Visible in the
distant background sky is the band of our
Milky Way Galaxy
and the
Andromeda galaxy.
A powerful
coronal mass ejection from the Sun
caused auroras to be seen as far south as
Wisconsin, USA.
As the Sun progresses away from its
current low in surface activity toward a
solar maximum
a few years away, many more
spectacular
images
of
aurora are expected.
