The name ‘Aurora’ comes from the Latin word for sunrise or the
Roman goddess of dawn. An aurora is a natural light display in the sky,
usually of greenish color but sometimes red or blue. This natural phenomenon
usually occurs in areas known as the ‘auroral zone’ near the poles of the
Arctic in the north and Antarctic in the south.
The effect is known as the aurora borealis (or the Northern Lights) in Northern
hemisphere latitudes. In Southern hemisphere latitudes the effect is known as
the aurora australis (or the Southern Lights).
Aurora is caused by the collision of energetically charged particles with
atoms in the high altitude thermosphere within our atmosphere. Auroras are
associated with the solar winds that flow past Earth. These winds flow out
from the Sun and contain plasma particles (ionized gas) which gets pulled into
the Earth’s magnetic pole fields, as they accelerate towards the Earth,
collision occur between these ion particles and nitrogen and oxygen atoms in
our atmosphere, releasing energy in the from of amazing aurora lights.
Auroras also occur on other planets in our solar system including
Jupiter, Saturn, Uranus, Neptune and Mars. Similar to Earth’s aurora, the
lights have been seen close to other planets magnetic poles. The aurora often
appear as “curtains” of folding light constantly changing shape. Old folktales
have suggested that the aurora can create brief and faint noises such as
claps, static, or crackles heard on rare occasions by those on the ground.
Recent scientific research has shown that this could in fact be true with
clapping sounds recorded during an aurora display.
