Like its northern sibling, the aurora australis is strongest in an oval centered on the south magnetic pole. This is because they are the result of collisions between energetic electrons (sometimes also protons) and atoms and molecules in the upper atmosphere … and the electrons get their high ...
We know more about the Aurora Borealis, than ever, but we are still learning what causes it, and we now know the light show can interfere with technology.
The Aurora Borealis (“Northern Lights”) or their southern counterpart the Aurora Australis are spectacularly colorful night-time displays, located above the Earth’s magnetic poles in the northern and southern hemispheres.
