Images fro Yohkoh, a joint Japanese-American-British satellite, are giving scientists new insights into the most violent events on the sun. The satellite's two telescopes can take image in both low- resolution and high-energy X-rays, and can reveal detail down to just a few thousand kilometres across. And Yohkoh can take an almost continuous series of images giving scientists a blow-by-blow account of the events. Data from Yohkoh suggests that the behaviour of loops in the solar corona may be responsible for solar flares. But the additional information has, if anything, only complicated our understanding - it would appear that somee of the events break the laws of physics!
