 As
magical as they appear, the northern lights are a subject of science.
The aurora borealis (as science knows them) begins 149 kilometers
from the sun’s surface as energetic particles are carried
on solar winds. After a trip to earth at speeds of up to 1,000 kilometers
per second, the particles that are not deflected by the earth’s
magnetosphere are trapped in the magnetic field. These particles
rush to the Polar Regions where access to the atmosphere is easier.
When they come into contact with earth’s oxygen and nitrogen
atoms, they become excited electrons that release light as they
settle down once again.
The northern lights are a gift to those who live in Canada’s
north and Alaska. This heavenly light show in the sky can vary from
light to intense greens, with blends of red and purple. This spectacle
of lights is an unforgettable show with different shapes that form
bands, arcs and shields in the sky. Some are stationary, some move
slowly, others fly by quickly in the sky. When the conditions are
just right, you can hear them crackle. The best part is you don’t
need a ticket to see this performance. All you have to do is get
away from the city lights and get north.
While the northern lights can be seen year round in Canada, they
are best viewed in fall and winter when the nights are longer. The
aurora borealis appear frequently at the more northern latitudes
of Canada; however they regularly appear north of the ~53rd parallel
as well.
The best time of day for viewing is between 10 p.m. and 2 a.m.
