light+ When a large number of electrons come
from the magnetosphere to bombard the
atmosphere, the oxygen
and nitrogen can emit
enough light for the eye
to detect, giving us
beautiful auroral displays+ This ghostly light
originates at altitudes of
100 to more than 400
km+
The color of the aurora
depends on which gas
oxygen or nitrogen is
being excited by the
electrons, and on how
excited it becomes+
The color also depends
upon how fast the electrons are moving, or how
much energy they have at
the time of their collisions+
High energy electrons
cause oxygen to emit
green light (the most familiar color of the aurora),
while low energy electrons
cause a red light+ Nitrogen
generally gives off a blue
light+ The blending of these
colors can also lead to purples, pinks, and whites+

to recognize the scientific
phenomenon of aurora ,
the light of god that
showed the pathway to
thousands and thousands
of lost riders a safe journey
to their loved one; on the
darkest days of their lives+

electromagnetic environment has made it possible
