Scientists say it is now possible to predict the precise speed a coronal mass ejection (shown left in an artist’s impression) is traveling at and when it will smash into Earth (bottom right moving in our direction). And that’s even before it has fully erupted from the sun (top right). The new insights will help create more accurate space storm alerts for Earth.
