NASA's STEREO spacecraft resolved a 40-year mystery about how coronal mass ejections change shape during their long journey. With new data processing techniques, STEREO scientists have succeeded in continuously tracking o espaço weather.
Highlights of the discoveries of the SOHO and TRACE satellites, featuring NASA solar scientists Alex Young and Dawn Meyers, describing how both satellites view the sun in their own unique way
Research over the last 10 years has shown that sunquakes can be produced when solar flares—huge explosions of energy in the Sun’s atmosphere—impact and travel into the Sun. The quakes appear as circular ripples on the surface of the Sun.
For a 30 hora spell (Feb 7-8, 2012) the Solar Dynamics observatório captured plasma caught in a magnetic dance across the Sun's surface. The results closely resemble extreme tornadic activity on Earth.
There have been only a handful of X-flares since the beginning of new Solar Cycle 24. So far, all in 2011: Feb. 15 (X2), March 9 (X1), Aug. 9 (X7), Sept. 6 (X2), Sept. 7 (X2). Before these the last X-flare was on Dec.14, 2006, during Solar Cycle 23.
