Auroras Over Both Earth Poles
Explanation:
Auroras in the north and south can be nearly
mirror images of each other.
Such mirroring had been suspected for centuries but
dramatically confirmed only last month by detailed images from
NASA's orbiting
Polar spacecraft.
Pictured above, a time-lapse movie shows
simultaneous changes in
aurora borealis, at the top, and
aurora australis, at the bottom.
A cloud of electrons and ions moving out from the Sun on
October 22 created the
auroras.
The
solar explosion that released the
particles occurred about three days earlier.
