Auroras Dancing in Unison
On the subject of Auroras, this photo from the POLAR satellite (superimposed on the Earth) shows that the Northern and Southern Lights, Aurora Borealis and Aurora Australis occur simultaneously! They are part of a huge electric circuit powered by Earth's internal dynamo. Positive and negative, dancing in unison like Ying and Yang. How beautiful, wonderful and little-understood this planet is.
Saturn's little moon Enceladus contains an internal heat source. Radiation turns water molecules into ionised gas spiralling around the moon's centre. A magnetic field is generated with the "positive" pole in the South and the "negative" pole in the North. Charged particles spiral around magnetic field lines to form twin jets, the classic sign of a singularity. The Northern jet is composed of electrons which are absorbed by Enceladus' interior. The Southern jet is composed of heavier ions which penetrate these layers to create a "hot spot" at the South Pole.
The way to succeed in science is to ask questions that haven't been asked. We know that the Antarctic contains huge submerged lakes warmed by Earth's internal heat. Is cold Antarctica really a "hot spot"? Further research will tell!
