Thursday of the world “Auroras” (borealis and australis )

I think everyone of us have heard about this beautiful lights called “Aurora” but only a few of us have seen one in real life, Today I wanted to share a little about this lights. (Which to be honest I just realized there were 2 kind of them Borealis and australis (northern and southern))

Well, the Aurora is a light caused by the collision from particles and atoms causing a magnetic effect which causes the lights that we know, The Aurora is a common phenomena, but is divided in 2 ways the diffuse and the discrete ones.

A diffuse one is invisible to naked eye, but the Discrete can glow in the night sky, because their glow is too weak for being seen in the sunlit sky.

This light appears in the geomagnetic poles (we call them south and north pole xD)  and depends from the site the way that we call them… Borealis in the north and Australis in the south. Basically they are the same the only that changes is the place where they are.

looking them closely they are so beauty, they usually gain a green color, (sepia for color blind people xD Check the article) but sometimes turn blue or red as we can see, also their shapes can change or keep static… if you have time to see one of them enjoy !!
