Although magnetic field lines are invisible, we know they exist on the Sun by looking at features called " coronal loops" and " prominences" rising up into the solar atmosphere.

尽管磁力线看不见，我们却知道其存在于太阳上，通过观察被称为“冕环”和“日珥”的特殊现象，“冕环”和“日珥”会一路上升到太阳的大气层。

The material flowing through a coronal loop carries enough energy to power Earth for thousands of years, and when those loops break, they can whip billions of tons of charged particles out into space.

流过日冕环的物质携带的能量足以为地球提供数千年的能量，当这些环破裂时， 它们可以将数十亿吨带电粒子鞭打到太空中。
