Scientists have found a way to spot active regions of the sun, below the solar surface, a full day or two before they erupt as sunspots on our nearest star, researchers said.
Sunspots, which are temporary dark splotches on the sunwith strong and concentrated magnetic fields, remain largely a mystery, but a team of astronomers has developed a new technique to detect these dynamic regions deep within the sun before they become visible on the surface. This new method, which measures acoustic waves beneath the sun's surface, could help scientists create better and more accurate ways to forecast space weather and potentially dangerous solar storms.
