Natural Phenomenon

Beautiful Aurora

        Aurora is a phenomenon that shows glow of burning at the layer of the ionosphere from a planet as a result of the interaction between the magnetic field of the planet with charged particles that being speared by the Sun or the solar wind. 

      The word "aurora" is derived from the name of the Roman goddess Aurora who traveled from east to west announcing the coming of the sun

    Aurora is the light that was created in the air caused by atoms and molecules collide with electrically charged particles, mostly electrons and protons that comes from the Sun. The particles were catapulted from the Sun at a speed of more than 500 miles/seconds and sucked by the magnetic field of the earth around the North Pole and the South Pole.

       An important part of the mechanism of the aurora is the solar wind. The solar wind is a stream of particles coming out of the Sun. The solar wind will move some amount of electricity in the atmosphere (the Van Allen Belt). The energy will accelerate particles into the upper atmosphere, and then it will crush with a variety of gas. So the result is the variety colors in the space. 

      There are a view type of Aurora based of it's shape.

1. Arc Aurora has a shape like the rainbow in the night sky.

1. Corona Aurora appear as a crown of diferging rays of light.

1. Diffuse Aurora is the rarest type. It has a featureless glow and difficult to spot with the naked eyes.

1. Drapery Aurora is the common type of Aurora, which ripples like a curtain.

     Aurora also can be differentiated by it's location. There are two types of Aurora based on it's location, Aurora Australis, which only can be seen in the South Pole and Aurora Borealis, which only can be seen in the North Pole.

     Aurora Australis also known as the southern light. This type of Aurora visible in high places, but when we see it from a distance, it seems like the aurora is on the line of the horizon. Aurora is typically green, but sometimes red or reddish as if the Sun were rising. That kind of Aurora can be seen from some places, especially in the southern parts of the Earth, like Antarctic, South America, Australia, New Zealand.

     The Aurora Borealis is a kind of aurora that is called the northern lights. The name itself comes from the word Borealis Boreas from Greek that means North wind. There is no different between Aurora Australis and Borealis, only it happend in different location. Aurora Borealis happen in the northern part of earth, north America (New Orleans, Alaska, and Canada, Iceland, northern Norway.

     The result caused by Aurora are hot plasma and variety of colors in the night sky. The hot plasma only happen to an Aurora called Aurora Theta because it’s plasma layer affected by a hot temperature.

    The colours of the Aurora depends on which atom is struck and the altitude of the meeting.

1.    Red aurora happens due to electron collisions with oxygen atom in 150 miles above earth.

2.    Green aurora happens due to electron collisions with nitrogen atom in 100 miles above earth.

3.    Purple aurora happens due to electron collisions with oxygen atom in 60 miles above earth.

4.    Blue aurora happens due to electron collisions with nitrogen atom in lower than 60 miles above earth.

There are some unique facts about Aurora

1.     Aurora not only happen on earth, but also in other planet’s solar system. 

2.     Aurora can move from the North to South 

3.     Aurora has a cold temperature, so it looks like cold fire in the nigt sky. 

4.     Auro ra will look even more beautiful if you are using sophisticated cameras
