After the Sun ejected a violent mass of fast-moving plasma into space on October 9, 2021, ESA waited for the storm to strike. A few days later, the coronal mass ejection (CME) arrived at Earth, crashing into our planet’s magnetosphere, and lighting up the sky.
CMEs explode from the Sun, rush through the Solar System and while doing so speed up the solar wind – a stream of charged particles continuously released …
