Astronomers peer inside stars, finding giant magnets

Astronomers have for the first time probed the magnetic fields in the mysterious inner regions of stars. Using a technique called asteroseismology, which uses sound waves generated by turbulence on the surface of stars to determine their inner properties, the scientists found that the fusion-powered cores of red giants, stars that are evolved versions of our sun, are strongly magnetized. The findings will help astronomers better understand the evolution of stars. —> Read More
