The Earth is constantly enveloped by solar winds, a rarefied flow of hot plasma gas of free electrons and positive ions, emitted by the Sun. The magnetosphere is full of trapped plasma as the solar wind passes the Earth.
The flow pattern of magnetospheric plasma is from the magnetotail toward the Earth, around the Earth and back into the solar wind through the magnetopause on the day-side. In addition to moving perpendicular to the Earth’s magnetic field, some magnetospheric plasma travel down along the Earth’s magnetic field lines.
Many cultures have stories about the lights in the sky, whilst some innuit tribes believe in a souls pathway from Heaven and Earth, in Chinese mythology, zhúlóng, meaning Dragon, literally: “illuminating darkness” is the source of early dragon legends. An aurora (plural: aurorae or auroras) is a natural light display in the sky particularly in the high latitude (Arctic and Antarctic) regions, caused by the collision of energetic charged particles with atoms in the high altitude atmosphere (thermosphere). The charged particles originate in the magnetosphere and solar wind and, on Earth, are directed by the Earth’s magnetic field into the atmosphere
Magnetospheric electrons which are accelerated downward by field-aligned electrons are responsible for the bright aurora features. The un-accelerated electrons and ions are responsible for the dim glow of the diffuse aurora.
