Spurting Plasma



A stream of plasma burst out from the sun, but since it lacked enough force to break away, most of it fell back into the sun (May 27, 2014). The video, seen in a combination of two wavelengths of extreme ultraviolet light, covers a little over two hours. This eruption was minor and such events occur almost every day on the sun and suggest the kind of dynamic activity being driven by powerful magnetic forces near the sun's surface. › View 'Spurting Plasma' video Image credit: NASA/Solar Dynamics Observatory via NASA http://ift.tt/1vu9bYg
