Interplanetary spacecraft capture a coronal mass ejection component hidden from Earth
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 ...
Stellar eruptions in the laboratory: First experimental evidence for their suppression in strong magnetic fields
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 ...
