Spiral Aurora over Icelandic Divide
Explanation: Admire the beauty but fear the beast. The beauty is the
aurora overhead, here taking the form of a great green
spiral, seen between picturesque clouds with the bright Moon to the side and stars in the background. The beast is the wave of charged particles that creates the
aurora but might, one day, impair civilization. In 1859, following
notable auroras seen all across the globe, a pulse of charged particles from a
coronal mass ejection (CME) associated with a
solar flare impacted Earth's
magnetosphere so forcefully that it created the
Carrington Event. This assault from the Sun compressed the
Earth's magnetic field so violently that it created
high currents and
sparks along
telegraph wires, shocking many
telegraph operators. Were a
Carrington-class event to impact the Earth today, speculation holds that
damage might occur to global power grids and electronics on a scale never yet experienced. The featured aurora was imaged in 2016 over
Thingvallavatn Lake in
Iceland, a lake that partly fills a fault that
divides Earth's large Eurasian and North American
tectonic plates.
