Physics behind unusual behavior of stars' super flares discovered

Our sun actively produces solar flares that can impact Earth, with the strongest flares having the capacity to cause blackouts and disrupt communications—potentially on a global scale. While solar flares can be powerful, they are insignificant compared to the thousands of "super flares" observed by NASA's Kepler and TESS missions. "Super flares" are produced by stars that are 100–10,000 times brighter than those on the sun.
