| 1 | A coronal mass ejection can cause problems on Earth. | |
| 2 | Coronal mass ejections have affected power stations in the past. | |
| 3 | The event's simultaneous launch of particles into space is called a coronal mass ejection (CME). | |
| 4 | Both flares and coronal mass ejections can create space weather if aimed at Earth. | |
| 5 | And the number of massive stars ejected this way matches up well with actual observations of OB runaways. |
