THE NORTHERN LIGHTS
THE LONGEST LIST OF THE LONGEST STUFF AT THE LONGEST DOMAIN NAME AT LONG LAST
The Northern Lights
are a beautiful spectacle that takes place in the northern part of
Alaska. The natural light show, that is considered one of the
natural Seven Wonders of the World, is so brilliant that it can be
seen from many different parts of the world. Although it may seem as
though these lights are magical, there are actually scientific
reasons for why this beauty transforms the night sky into something
These lights, also called Aurora
Borealis, are caused by the locations of the sun that are hotter
than other parts of the sun. These ‘hot spots’ as they are known,
produce solar wind and that wind travels through the Earth’s
atmosphere. The molecules in the wind gain speed and get hotter and
they start to glow. Depending on how hot the hot spots are, they
produce more wind and the lights become more active.
The Northern Lights are comprised of
many different colours including green, red, blue, and yellow. The
different colours are created when different types of gases hit
different heights in the atmosphere. Along with the many different
colours, they can also have many different brightness levels. On
Earth, brightness is measured on a scale where the Milky Way is the
brightest and the full moon is the dimmest. The Northern Lights
range all over this scale.
There are also different types of light
within the Northern Lights. The first is called Quity Arces. This
type of light gives the appearance of curtains or bands of light.
The light can also appear as shafts or bundles of light and that
type is called Raide Arces. The third type is appropriately called
Diffuse Patches due to their thin and scattered appearance. The
lights also range greatly in thickness, with some of them being over
100 meters thick. Some are also hundreds of kilometers tall and over
one thousand kilometers in length.
Although the scientific reason is known
today as the cause for the lights, there used to be many myths about
them as they continued to be one of the last mysteries of the
natural world. It was once believed in Norway that dead warriors
were fighting and this caused the lights in the sky. The Vikings
believed them to be messengers from the female god Odin and that she
would mark those that were to be killed in battle. Those in Lapps
and Finland believed that the lights were messengers sent by God.
Of course the Northern Lights can still
be seen today. Because they are only visible in some parts of the
world, Alaska gets many visitors every year, each one hoping to
catch a glimpse of the mystical lights.
