New analysis method predicts disruptive solar flares

Solar flares--violent explosions on the surface of the sun--can send blasts of radiation hurtling toward Earth. While the planet's magnetic field protects humans on the surface, powerful solar flares can disable satellites, power grids and radio communications. But scientists aren't sure exactly what triggers solar flares, which makes it difficult to predict when one will occur. One theory suggests these massive explosions can be set off by small disturbances in the sun's magnetic field. Now, re...
