| 12/08/03 | EXTENSIVE DESTRUCTION POWERS SOLAR EXPLOSIONS - Large-scale destruction of magnetic fields in the sun's atmosphere likely powers enormous solar explosions, according to a new observation from NASA's Ramaty High Energy Solar Spectroscopic Imager (RHESSI) spacecraft.

| 07/21/03 | The Sun's big, bright, explosive flares are the attention grabbers, but tiny, more numerous microflares may have nearly as much influence on the solar atmosphere, according to new data from the University of California, Berkeley's RHESSI satellite.

| 05/28/03 | In December of 2002, RHESSI caught a serendipitous glimpse of a gamma ray burst, while observing the Sun. Gamma Ray bursts are thought to be the most energetic explosions in the Universe resulting from an extremely violent supernova death of a star. RHESSI's unique observation of the gamma ray burst has reveled some surprising new results in the study of these mysterious explosions.
