During a coronal mass ejection (CME), the sun hurls billions of tons of magnetized plasma into space. These eruptions are among the most powerful events in the solar system, and when they are aimed toward Earth, they can ...
An international team of astrophysicists and plasma physicists has provided the first experimental evidence that strong magnetic fields surrounding active stars can completely suppress coronal mass ejections. This offers ...
