  Study Finds Coronal Loop Flickers Could Predict Solar Flares Hours in Advance

  NASA's Solar Dynamics Observatory has revealed a potential breakthrough in predicting solar flares. Scientists observed brightness fluctuations in coronal loops—plasma structures in the Sun's atmosphere—that intensify hours before solar flares occur. This discovery, with a prediction accuracy of 60–80%, may provide 2–6 hours of advance warn...
