The Aurorae


Scientific books say that an Aurora is produced when an ejection of solar mass collides with the North and South poles of the Earth’s magnetosphere, producing a diffuse but predominantly light projected in the Earth’s ionosphere.

In easy language we can say that the Sun spits particles continuously (some of them charged: protons and electrons) that are denomined Solar Wind, but sometimes there are significant eruptions that complement the wind. These eruptions have the main function of annoy: charged particles travelling at high speed (300-1000 km/s) bathing our expensive satellites… it can not be good for them. Actually it is the main problem they have; fortunatelly we and our beloved computers are under the comfortable atmosphere.

Back to the Aurorae, these particles traveling into the space feel a strong attraction towards the Earth, from the poles. When these particles come into the atmosphere some of them crash with some atoms and molecules (mainly oxigen and nitrogen), exciting them so fast that they emit a faint light before to came back their original state.

  1. In my opinion, this is a very interesting topic. You have given a very broad definition which you have explained very simple. People who don’t have a scientific background will be able to understand this without much help from a dictionary. So I compliment you on a nice choice of topic and a job well done.

  2. Interesting as well as attractive topic indeed! First paragraph with definition is good but I think the second paragraph needed to be more simplified. You could add some more information related to the interest of common people. Anyway you have tried your best.

    Your story line is ok, but the many language errors and the ensuing unclarity hamper flow.
