A twist on the sun is throwing solar scientists for a loop.

For the first time, researchers have watched the sun’s magnetic field force plasma into a spring-shaped curl during a powerful solar eruption known as a coronal mass ejection, or CME. The new observations contradict previous research suggesting that the twisted plasma structures are precursors of CMEs, which can disable satellites and disrupt air travel when directed toward Earth. The new findings appear August 28 in Astrophysical Journal Letters.
