Did you know that the difference between aurora borealis and aurora australis is given by the hemisphere in which it occurs. Aurora (atmospheric phenomenon), is alight that occurs at high altitudes, usually above 60 ° latitudes, but it has also been seen in other areas. As occurs in the northern or southern hemisphere, it is called the aurora borealis and aurora australis. A polar aurora occurs when a solar mass ejection collides with the north and south poles of the Earth’s magnetosphere, producing a diffuse but predominantly projected light onto the Earth’s ionosphere, consisting of proton particles that spread color. Note that, without an adequate magnetosphere, these light morphs produce large particle megatons do make a huge damage and they increase the temperature. Thus, through the filter that we can visualize the magnetosphere is mostly in Alaska (A. borealis).
