Astronomers peer inside stars, finding giant magnets
Pasadena CA (SPX) Oct 23, 2015
Astronomers have for the first time probed the magnetic fields in the mysterious inner regions of stars, finding they are strongly magnetized. Using a technique called asteroseismology, the scientists were able to calculate the magnetic field strengths in the fusion-powered hearts of dozens of red giants, stars that are evolved versions of our sun. "In the same way medical ultrasound uses sound waves to image the interior of the human body, asteroseismology uses sound waves generated by turbulence ... read more
