Natural Phenomenon : Aurora
Most people recognize aurora as one of the creation of Walt Disney princess, which is The Sleeping Beauty. But as you all may already know, aurora is also a name of a stunning natural light phenomenon which exists in the Northern and Southern Pole. So, first of all, what is aurora?
Aurora is a natural phenomenon which is known by a display of a natural-coloured (green, red, yellow or white) light in the sky. It is a light show which is caused when electrically-charged particles from the sun collide with particles from gases such as oxygen and nitrogen present in the earth's atmosphere.
In ancient Greece and the Romans, aurora borealis is derived from the Greek words "Aurora" meaning "sunrise" and "boreas" meaning "wind". The Greeks held that Aurora was the sister of Helios and Seline, the sun and moon respectively, and that she raced across the early morning sky in her multi-coloured chariot to alert her siblings to the dawning of a new day. The Romans also associated the Northern Lights with a ner day believing them to be Aurora, the goddess of dawn.
Aurora sometimes referred to as polar lights, divided into two types; northern lights (Aurora Borealis) and Southern Lights (Aurora Autralis). These natural lights display in the earth's sky, predominantly seen in the high-latitude regions (around the Arctic and Antarctic).
Auroras are the result of disturbances in the magnetosphere caused by solar wind. These disturbances are regularly strong enough to alter the trajectories of charged particles in both solar wind and magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/exosphere).
These are fun facts of aurora :

These are fun facts of aurora :
- They are visible from space
- Other planets have them
- The lights can move south
- Cold fire
- Camera see it better than your eyes
- You can't predict a show
