New solar telescope unveils the complex dynamics of sunspots' dark cores

Groundbreaking images of the Sun captured by scientists at NJIT's Big Bear Solar Observatory (BBSO) give a first-ever detailed view of the interior structure of umbrae - the dark patches in the center of sunspots - revealing dynamic magnetic fields responsible for the plumes of plasma that emerge as bright dots interrupting their darkness. Their research is being presented this week at the first Triennial Earth-Sun Summit meeting between the American Astronomical Society's Solar Physics Division...
