It’s been discovered that electrons descend from space on Alfvén waves to create the aurora borealis

Physicists have definitive evidence that the aurora borealis is the result of electrons ‘surfing’ across the cosmos on powerful party waves. Scientists have known for a while that aurorae occur when energised particles from the Sun soar across space and crash into Earth’s magnetosphere. Those energised particles ride our planet’s magnetic field lines into the upper atmosphere, where they collide with oxygen and nitrogen molecules, releasing dazzlingly coloured light in the process. But there’s still a big lingering question about the aurora process: How do those solar particles pick up enough speed and energy to crash into Earth’s atmosphere with such force?
