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 Jökulsárlón, 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.
