A strong magnetic field can disrupt a star’s ability to produce the fountains of matter called coronal mass ejections.
The Sun’s surface occasionally erupts with a geyser of matter (pictured) called a coronal mass ejection, but many similar stars lack such features. Credit: Solar Dynamics Observatory/NASA/Science Photo Library
