In the above still captured from the new NASA IMAGE aurora australis video a faint tail or arc is visible streaming from the surface of the Antarctic continent precisely where the south polar opening is located. The stream of charged particles emanate from this opening in the Earth's mantle until it hits the ionosphere where it then "ignites" into the familiar auroral display.
In this video still, precisely where the "tail" or arc in the first snapshot emanates from the surface of Antarctica, a hole or black zone is visible in the center of the aurora australis. This is the exact point where the aurora is pouring through the south polar opening in the Earth's crust.
When you watch the video of the aurora australis, allow it to load, then run the cursor back slowly to watch the video frame by frame and observe how it pours from the Earth's southern opening.
