Alfven waves drive stable electric fields that power auroras
Tokyo, Japan (SPX) Feb 08, 2026
The shimmering curtains of the aurora form when energetic electrons plunge into Earths upper atmosphere and collide with atoms and molecules, releasing light across the polar skies. For decades, scientists have known that these electrons are accelerated by intense electric fields above the auroral regions, but they lacked a clear explanation for how those fields are generated and sustained in ne
