=__**What is an aurora?**__ =

An aurora is a natural light display in the sky. All auroras are unique. Some look like torrnados and clouds. Some look like windy rivers in the sky. They are very colourful and all the colours blend together. Auroras can be green, aqua, purple, red or pink. You can find auroras at the very top and bottom of the earth, near the North and South Poles.

=__**What causes an aurora?**__ =

Aurora is caused when the sun sends out particles into space called "solar wind". When the solar wind hits the earth, it mixes with the magnetic field. Aurora occurs in the North Pole and South Pole because this is where the magnetic field is weaker, so more of the solar wind gets through and interacts with the atmosphere and produces these waves of different colour. And that is how auroras are created.

= __Why is it named aurora?__ =

Auroras is named after the Roman goddness of dawn. They called it aurora beacause when it is dawn it is all red and pink and people say that it looks like dawn and the latin word for dawn is Aurora. Sometimes people call them the aurora borealis, the northern light or the sourthern light.

=__What do people think it is?__ =

Sami people that lives in Sweden, Norway and Finland think that the aurora is a tail of a fox. Roman Emperor Tiberius saw the aurora and thought it was a fire. He sent fire engines to a city but it was actually the aurora. Northern Swedish people thought that the aurora was something to be respected by. The children was told to behave and if they missed behaved it will be really bad.
