now for some final thoughts on the
Northern
Lights who would have guessed long ago
what causes the
Aurora countless Atomic and subatomic
particles released by the sun in
resonance with its 11-year cycle stream
among the planets at speeds up to a
million miles an hour these charged
particles see and respond to Earth's
magnetic field the positive and negative
charges split North and South they then
gather and pulse in ways still
mysterious as they collide with
molecules of Earth's upper
atmosphere the collisions render the air
a glow creating one of the most colorful
and striking sights of the Arctic night
as the sky fills with dancing curtains
of light no doubt about it the Aurora is
complex to understand it requires a
branch of advanced physics called
Magneto hydrodynamics a field that's
been known to make strong men weep
meanwhile a Aurora has been and
continues to serve as a fertile source
of art mythology and Legend among Arctic
peoples and their visitors as it leaves
viewers in silent awe of its majesty and
Beauty it's a curious thing about the
universe behind the most stunning
phenomena to behold lie some of the most
challenging problems in
astrophysics from the colorful
turbulence within planetary atmospheres
to stars in the throws of death to the
Majestic patterns of spiral galaxies to
the large scale structure of the
universe itself what distinguishes the
Aurora among them is that you don't need
a telescope to see it just your eyes and
a ticket to the
Arctic and that's the cosmic
perspective
