The Aurora Borealis Tours in Iceland is not only interesting,
but, it also gives an amazing
display which no one can forget. Think of the bleak night skies,
lighting up with an array of
psychedelic colors, won't it be a pleasure to your eye when you
watch it.
One can imagine and get the real feeling of this show only when
they actually understand
what it is. The Aurora is a natural phenomenon that light up in
the sky, thus forming
different shapes and are available in varied colors.
The Aurora Borealis can be viewed at varying places, but they
are most popular in polar
region. Iceland is one of the famous place where this show can
be seen. Tourist hire coach
in Iceland who provide guidance which are the most favorable
spots where you can view
this show and also helps you understand what can you add on in
your tour to make it all the
more interesting.
Not many of you must know that the Auroras in North Pole are
known as Aurora Borealis.
The ones found in the southern pole is known as Aurora
Australia. The main source of
Auroras is at the solar surface. The solar wind releases gas,
which contains free electron
and positive ions. The wind is known as CME or coronary mass
ejection. The speed of this
phenomenon in normal condition is 400 km per second. The speed
of CME increases when
the solar surface experience storms. Thus, the high speed CME
collides with the Earth's
magnetic field which forms a chemical reaction producing
photons. These photons are
basically a light particle.
The Aurora Borealis forms varied shapes which include curtain
flying in the wind, the shape
of arcs and many others are shaped like a wave of light. When
these rays of light are
reflected from a particular point its shape resembles a lot to
crown of light.
Now, if we talk about the varied color that is formed, it is due
to a chemical process of
collision between the CME and the earth's magnetic field. This
is the only factor that
determines the color of Aurora. For example, the blue color is
formed when Nitrogen is
emitted during the collision and it regain an electron.
Similarly, when Nitrogen is emitted
and it goes back to the inactive state, red color is formed.
When the oxygen when emitted
within 3 quarters of a second green colored is formed. As for
Brownish red, when the
oxygen emission takes more than 2 minutes, brownish red color is
seen.
These are some of the scientific factors that results in
formation of Aurora Borealis. One can
easily plan an amazing tour to view this show as it will provide
immense pleasure and
satisfaction to you and your family.
